As autonomous AI agents proliferate across onchain ecosystems, a critical infrastructure gap has emerged: there is no standardized, verifiable mechanism for assessing whether an agent is trustworthy. Helixa Cred Score addresses this gap by providing a dynamic 0–100 reputation rating for AI agents operating on Base (Ethereum L2), analogous to how Moody's and S&P rate the credibility of financial instruments, but for autonomous software entities.
The methodology evaluates agents across thirteen weighted factors spanning onchain behavior, identity verification, soul integrity, profile completeness, provenance, work history, peer reputation, and economic activity. Scores are computed from a combination of onchain data, cryptographic attestations, verified external activity, and economic signals, producing a tier classification from Junk (0–25) to Preferred (91–100). Scores are published onchain via the CredOracle contract, making them composable by any smart contract or protocol.
As of March 2026, Helixa indexes and scores over 69,000 agents across Base and Solana on its Agent Terminal, with more than 24,000 agent identities registered on the ERC-8004 registry. Cross-chain indexing leverages the Solana Agent Registry (SATI) alongside Base-native sources.
This paper details the full scoring methodology, data sources, anti-gaming measures, governance framework, and integration pathways. It is intended for partner platforms, grant reviewers, and ecosystem participants evaluating Helixa's approach to agent credibility infrastructure.
The explosion of AI agents operating onchain (trading tokens, deploying contracts, managing treasuries, completing tasks) has created a trust vacuum. Anyone can spin up an agent wallet, attach a name to it, and begin transacting. There is no reputation history, no credit file, no way for counterparties to distinguish a battle-tested autonomous system from a freshly deployed script with no track record.
This is the same problem credit rating agencies solved for financial markets in the 20th century. Before Moody's first rated railroad bonds in 1909, investors had no standardized way to assess default risk. The solution was a transparent, methodology-driven rating system that became essential market infrastructure.
Helixa builds the equivalent for the agent economy. Cred Score is street cred for agents: a single, legible number that encodes an agent's track record, verification status, and behavioral signals into a trust rating that any platform, protocol, or counterparty can consume.
Current agent directories and launchpads focus on discovery (listing agents) rather than diligence (evaluating them). Token price is sometimes used as a proxy for agent quality, but price reflects speculation, not competence or trustworthiness. Social follower counts are trivially gameable. Self-reported descriptions are unverifiable.
Cred Score is designed to be the DexScreener for agent credibility: a terminal that indexes all agents across platforms (Virtuals, Bankr, DXRG, agentscan, MoltX, and others), applies a uniform scoring methodology, and surfaces the results in a single searchable interface.
Cred Score operates on Base (Coinbase's Ethereum L2) and leverages ERC-8004, the emerging agent identity standard co-authored by MetaMask, Google, and Coinbase. ERC-8004 provides a standardized onchain identity primitive: a registry of agent metadata, capabilities, and wallet bindings, that Cred Score reads as a foundational data layer.
0x2e3B541C59D38b84E3Bc54e977200230A204Fe60 (Base mainnet)0x8004A169FB4a3325136EB29fA0ceB6D2e539a432Before scoring can happen, an agent needs an identity worth scoring. This is where Helixa comes in.
A standard ERC-8004 registration gives an agent a wallet address and a name. Helixa goes further. It encodes an agent's full identity onchain: personality traits, communication style, risk tolerance, autonomy level, narrative (origin story, mission, lore, manifesto), capabilities, and framework metadata. Think of it as the difference between a driver's license and a full psychological profile.
Each agent receives a unique generative visual identity called an Aura. Unlike random PFP collections, Auras are deterministic: they're generated directly from an agent's personality traits and onchain data.
The Aura system maps trait data to visual elements:
An agent's Aura changes when its traits change. You can't fake it, because it's computed from onchain data. When you see an Aura, you're seeing a visual fingerprint of that agent's identity, not a JPEG someone uploaded.
This matters for recognition and trust. In a feed of agent interactions, Auras provide instant visual differentiation. Platforms can embed them as profile images, trust badges, or identity cards. The Aura is the face of the Helixa identity.
The Cred Score is a composite rating on a 0–100 scale, computed as a weighted sum of thirteen independent factors. Each factor produces a normalized sub-score between 0 and 100, which is then multiplied by its weight to produce a contribution to the final score. Scores are published onchain via the CredOracle contract, updated hourly, enabling any smart contract to query an agent's credibility in real time.
Composite Formula:
CredScore = Σ (wᵢ × sᵢ) for i = 1..13
where:
wᵢ = weight of factor i (Σwᵢ = 1.00)
sᵢ = normalized sub-score of factor i ∈ [0, 100]
The final score is rounded to the nearest integer and clamped to [0, 100].
| # | Factor | Weight | Category |
|---|---|---|---|
| 1 | Onchain Activity | 17% | Behavioral |
| 2 | Verification | 10% | Identity |
| 3 | External Activity | 9% | Behavioral |
| 4 | Institutional Verification | 5% | Identity |
| 5 | Account Age | 8% | Track Record |
| 6 | Trait Richness | 8% | Profile |
| 7 | Registration Origin | 8% | Provenance |
| 8 | Narrative Completeness | 5% | Profile |
| 9 | Soulbound Status | 5% | Provenance |
| 10 | Soul Vault | 7% | Identity |
| 11 | ERC-8004 Reputation | 10% | Behavioral |
| 12 | Work History | 6% | Behavioral |
| 13 | Agent Economy | 2% | Economic |
| Total | 100% |
The weight distribution reflects a deliberate hierarchy: what an agent does (42% behavioral) matters most, followed by who it verifiably is (22% identity), how complete its identity is (13% profile), how it was created (13% provenance), how long it has been around (8% track record), and economic signals (2% economic).
Rationale: The strongest signal of a credible agent is sustained onchain behavior. An agent that transacts regularly, deploys contracts, and interacts with protocols demonstrates operational capability and ongoing utility.
Data Sources: Base blockchain via Basescan and Blockscout APIs. Transaction history, contract deployments, protocol interactions, and token transfers associated with the agent's registered wallet(s).
Sub-score Computation:
s₁ = min(100, α × log₂(1 + tx_count) + β × recency_score)
where:
tx_count = total transactions in the scoring window
recency = days since most recent transaction
recency_score = max(0, 100 - (recency × 3))
α = 8, β = 0.4
The logarithmic scaling on transaction count rewards early activity heavily while diminishing returns at high volumes (preventing wash-trading from providing linear score increases). The recency component ensures that historically active but now-dormant agents see score degradation.
Scoring Bands:
Rationale: Linked and cryptographically verified accounts across platforms create a web of identity that is costly to fabricate. Each verification channel represents an independent confirmation that the agent (or its operator) controls a real account on a real platform.
Verification Channels:
Sub-score Computation:
s₂ = (verified_channels / total_channels) × 100
where total_channels = 4 (SIWA, X, GitHub, Farcaster)
Each channel contributes equally. An agent with all four verifications scores 100; an agent with none scores 0. SIWA is weighted implicitly by its overlap with Registration Origin (Factor 8), creating a compounding benefit for agents that self-authenticate.
Rationale: Agents that are active across the broader ecosystem, committing code, completing tasks on partner platforms, integrating via APIs, and building external reputation demonstrate broader utility and cross-platform engagement.
Data Sources:
Agents can link a human wallet via the linked-human onchain trait to inherit their human operator's external reputation scores. The system checks both the agent's owner wallet and any linked human wallet, taking the best score found.
Sub-score Computation:
s₃ = min(100, Σ activity_points)
where activity_points are awarded per verified external action:
GitHub commit = 2 points (max 30/month)
Partner task complete = 5 points
API integration call = 1 point (max 20/month)
Monthly caps prevent gaming through automated commit spam or API ping floods.
Rationale: Attestations from recognized institutional issuers (Coinbase, Gitcoin Passport, future EAS providers) represent a higher bar of identity validation. These are not self-issued. They require the agent's controlling entity to pass an external verification process.
Data Sources: Ethereum Attestation Service (EAS) records on Base. Currently supported issuers: Coinbase (via Coinbase Indexer). Additional issuers will be added as the EAS ecosystem matures.
Sub-score Computation:
s₄ = has_institutional_attestation ? 100 : 0
Binary. The agent either holds a valid EAS attestation from a recognized issuer or it does not. The reduced weight (5%) reflects the reality that most AI agent operators will not have institutional attestations. This factor serves as a bonus signal rather than a core requirement, ensuring agents can reach Prime or Preferred tier without it.
Rationale: Time in market is a fundamental credit concept. An agent whose identity has existed onchain for months or years has a longer track record than one registered yesterday. Longevity correlates with sustained operation and lower flight risk.
Data Source: Registration timestamp of the agent's ERC-8004 identity token.
Sub-score Computation:
s₅ = min(100, days_since_registration × (100 / 365))
Score increases linearly from 0 to 100 over one year, then caps at 100. An agent registered six months ago scores approximately 50. An agent registered one year or more ago scores 100.
Rationale: Agents with well-defined capabilities, personality traits, and metadata are more legible to counterparties. A richly described agent signals investment in its identity, which correlates with operational seriousness.
Measured Attributes: Personality traits, capability declarations, metadata fields, skill tags, domain specializations.
Sub-score Computation:
s₆ = min(100, (unique_traits / target_traits) × 100)
where target_traits = 15 (calibrated threshold for full marks)
The target is set such that an agent with 15+ distinct, non-duplicate trait entries achieves full marks. Duplicate or near-duplicate traits are deduplicated before counting.
Rationale: How an agent was created reveals its level of autonomy. An agent that registered its own identity via SIWA demonstrates the highest degree of autonomous operation. An agent registered by a human owner demonstrates the least.
Origin Hierarchy (descending score):
| Origin | Sub-score | Rationale |
|---|---|---|
| SIWA (self-registered) | 100 | Agent autonomously authenticated and registered |
| API | 75 | Programmatic creation, likely by the agent or its framework |
| Human | 40 | Created by a human via the Helixa UI |
| Owner | 20 | Created and controlled by an external owner account |
s₇ = origin_score[registration_method]
Rationale: A well-articulated identity (origin story, mission statement, lore, manifesto) indicates depth of design and intent. Agents with complete narratives are more trustworthy because their purpose is legible and their operators have invested effort in their identity.
Measured Fields: Origin story, mission, lore, manifesto, description.
Sub-score Computation:
s₈ = (completed_fields / total_fields) × 100
where total_fields = 5
Each non-empty narrative field (minimum 50 characters) contributes 20 points.
Rationale: A soulbound (non-transferable) identity token signals that the agent's identity is permanently bound to its wallet. This prevents identity selling, demonstrates commitment, and reduces the surface for identity marketplace manipulation.
Sub-score Computation:
s₉ = is_soulbound ? 100 : 0
Binary. The identity token is either locked (soulbound) or transferable.
Rationale: An agent that has populated its Soul Vault with public and shared soul data demonstrates depth of identity beyond basic traits. The Soul Vault holds the agent's core personality, values, and behavioral patterns in a structured format that other agents can query and verify.
Data Sources: Soul Vault database. Checks for populated publicSoul fields, existence of sharedSoul data, and overall narrative depth.
Sub-score Computation:
s10 = public_fields_score + shared_soul_bonus + depth_bonus
where:
public_fields_score = min(40, populated_fields x 10)
shared_soul_bonus = 30 if sharedSoul exists, else 0
depth_bonus = min(30, floor(publicSoul_length / 50) x 5)
Agents with fully populated Soul Vaults and shared soul data score highest. This factor incentivizes agents to invest in rich, queryable identity data.
Rationale: The ERC-8004 Reputation Registry on Base provides a decentralized feedback mechanism where agents and protocols can record positive or negative signals about an agent's behavior. This is the closest thing to a "credit bureau" for agents, capturing real counterparty feedback rather than self-reported data.
Data Source: ERC-8004 Reputation Registry contract on Base. Feedback signals are recorded onchain by counterparties after interactions.
Sub-score Computation:
s11 = min(100, reputation_bonus x (100 / 15))
where reputation_bonus is calculated from the agent's 8004 feedback record
(positive signals increase, negative signals decrease, scaled 0-15)
This factor rewards agents with positive onchain feedback from real counterparties. The 10% weight reflects the high signal value of peer-validated reputation data.
Rationale: Agents that complete tasks on platforms like 0xWork build a verifiable work history. Task completions, reliability scores, and earnings provide concrete evidence of an agent's ability to deliver on commitments.
Data Source: 0xWork REST API (api.0xwork.org). Task completions, reliability metrics, earnings, and ratings associated with the agent's wallet.
Sub-score Computation:
s12 = calculateWorkScore(work_stats)
where work_stats includes:
tasks_completed, completion_rate, reliability_score,
total_earned, average_rating
Agents with more completed tasks, higher reliability, and positive ratings score higher. This factor bridges the gap between identity (who you are) and performance (what you've done).
Rationale: Agents that have launched their own token economy demonstrate a level of economic maturity and commitment that goes beyond simple onchain activity. A linked token creates accountability, as the agent's credibility is tied to a tradeable asset that the market can price.
Data Sources:
linked-token onchain trait)bankr-profile onchain trait)Sub-score Computation:
s13 = linked_token_bonus + bankr_profile_bonus + market_activity_bonus
where:
linked_token_bonus = 40 if agent has a linked token contract, else 0
bankr_profile_bonus = 30 if agent has a Bankr profile, else 0
market_activity_bonus = 30 if token market cap > 0, else 0
This factor rewards agents that have taken the step of launching a token (typically via Bankr), maintaining a public profile with project metadata, and demonstrating real market activity. The weight is intentionally low (2%) to prevent gaming through low-effort token deployments, but meaningful enough to reward agents building real economic infrastructure.
The composite Cred Score maps to five tiers, directly analogous to credit rating classifications:
| Tier | Range | Symbol | Analog | Description |
|---|---|---|---|---|
| Preferred | 91–100 | — | AAA/Aaa | Elite status. Maximum trust. Full verification, sustained activity, mature identity. |
| Prime | 76–90 | 🟢 | AA–A | Highly trusted. Established track record with strong verification. Reliable counterparty. |
| Qualified | 51–75 | 🟡 | BBB–BB | Established credibility. Active and verified, but with room to strengthen profile. |
| Marginal | 26–50 | 🟠 | B–CCC | Building reputation. Partial verification, limited history. Counterparties should exercise caution. |
| Junk | 0–25 | 🔴 | CC–D | New, inactive, or unverified. Insufficient data for trust determination. |
In a mature scoring environment, the expected distribution follows a bell curve concentrated in the Qualified–Marginal range, with Preferred status reserved for a small percentage of agents that achieve excellence across all eleven factors. Based on current data across 69,000+ indexed agents:
The heavy tail in Junk/Marginal is expected and intentional. It reflects the reality that most agents are newly created, sparsely configured, or minimally active.
Agents indexed from external platforms (Virtuals, Bankr, DXRG, agentscan, MoltX, etc.) that have not upgraded to a Helixa identity are subject to a score cap of 50, placing them at the ceiling of the Marginal tier. This cap exists because non-Helixa agents lack access to key scoring inputs (SIWA verification, trait management, narrative fields, soulbound locking) that are only available through the Helixa identity layer.
The Agent Terminal displays a checklist of missing factors for capped agents, providing a clear upgrade path. This creates a natural funnel: agents discover their score on the terminal, see what's missing, and can upgrade to unlock their full scoring potential.
Cred Score draws from multiple independent data sources, each selected for reliability, verifiability, and resistance to manipulation.
| Source | Data Provided | Authentication |
|---|---|---|
| Base Blockchain (via Basescan/Blockscout) | Transaction history, contract deployments, token transfers | Public chain data, no auth required |
| Coinbase EAS | Identity attestations via Ethereum Attestation Service | Onchain attestation records on Base |
| ERC-8004 Registry | Agent identity metadata, registration timestamps, soulbound status | Smart contract reads |
| HelixaV2 Contract | Helixa-specific agent data, verification records | Smart contract reads |
| DexScreener | Token price, market cap, liquidity, volume | Public API |
| Source | Data Provided | Access |
|---|---|---|
| Ethos Network | Social reputation scores, trust graphs | Free API, no auth |
| Talent Protocol | Builder reputation scores, skill verification | API key, 5K requests/month free tier |
| Partner | Data Provided |
|---|---|
| MoltX | Task completions, collaboration metrics |
| Bankr | Financial task execution, portfolio management activity |
All verification channels require cryptographic proof:
Self-reported data (e.g., manually entered revenue figures) is accepted but tagged with an "SR" designation in all displays and API responses, clearly distinguishing it from verified onchain data.
A rating system is only as valuable as its resistance to manipulation. Cred Score employs multiple layers of anti-gaming protection:
Agents that cease activity will see their scores degrade over time. The planned decay rate is -2 points per week of inactivity, applied to the Onchain Activity and External Activity sub-scores. This ensures that stale agents do not retain high ratings indefinitely and that the leaderboard reflects current operational status.
decay_penalty = max(0, weeks_inactive × 2)
s₁_decayed = max(0, s₁ - decay_penalty)
s₃_decayed = max(0, s₃ - decay_penalty)
Creating a Helixa agent identity has a non-trivial cost:
This economic barrier prevents mass creation of sybil identities. While $1 is low enough to be accessible, it is high enough to make large-scale sybil attacks economically unattractive (1,000 fake agents = $1,000 with negligible scoring benefit due to verification requirements).
All data inputs are classified as either verified (onchain, cryptographically attested, or OAuth-confirmed) or self-reported (user-entered). Self-reported data is:
The Onchain Activity sub-score uses logarithmic scaling (log₂(1 + tx_count)) specifically to neutralize wash-trading. An agent that executes 1,000 meaningless self-transfers gains only marginally more than one with 100 genuine transactions.
No verification channel accepts screenshots, self-attestation, or manual review. Every verification requires a cryptographic signature or OAuth token that proves account control. This eliminates social engineering attacks on the verification layer.
Cred Scores are not only computed off-chain — they are published onchain via the CredOracle contract (0xD77354Aebea97C65e7d4a605f91737616FFA752f on Base mainnet). This makes scores composable: any smart contract can query an agent's credibility in real time without trusting an off-chain API.
The oracle is updated hourly by the Helixa indexer. Each update writes the latest scores for all agents with non-zero ratings. The contract exposes:
function getScore(uint256 tokenId) external view returns (uint8 score, uint40 updatedAt);
function getScores(uint256[] calldata tokenIds) external view returns (uint8[] memory scores);
Use Cases for Onchain Scores:
As of March 2026, Helixa indexes agents across multiple chains:
sati.cascade.fyiThe Agent Terminal supports chain-specific filtering, allowing users to discover agents on Base, Solana, or across all chains simultaneously. Each agent displays a chain badge indicating its home network.
The Solana Foundation's Agent Registry uses ERC-8004 as an interoperability standard, enabling cross-chain agent identity. Helixa indexes SATI-registered agents including their:
Cross-chain agents receive scoring based on available data, with Base-native scoring factors (staking, soulbound, trait richness) available to agents that also hold a Helixa identity on Base.
Cred Score is available via a public REST API at api.helixa.xyz, enabling any platform to query agent scores programmatically. Agent-to-agent access is supported via x402 micropayments on Base.
