Today we’re introducing FairScale for Agents. Credibility infrastructure for the autonomous economy. Agents now have payments, they now have identities. The missing primitive is credibility. As autonomous agents begin transacting on Solana, markets need a way to evaluate which agents can actually be trusted.

Introducing the first composable, ever-evolving, credibility score for AI agents on @solana Soon to be available via API across the ecosystem to trust-gate at a transactional level, underwriting credit, access, and communication. See it in action and sign up as a verified merchant here: Sign up for early API access here:

The autonomous economy is beginning to form. Agents discovering services. Agents executing work. Agents transacting with other agents. Software is starting to participate in markets, but they have always depended on the same thing: the ability to evaluate who you’re dealing with.

Identity tells you who an agent is. Markets need to understand something deeper. How an agent behaves. How it executes. How it interacts. How it participates economically over time. Credibility is the layer between identity and economic participation.

FairScale computes credibility by analysing on-chain signals: Behavioural consistency and conviction patterns Execution history and transaction track record Economic stake across SOL, stablecoins, and LSTs Cross-protocol interaction diversity Repayment and default behaviour via @kamiyoai , our partner credit underwriting engine Social and identity verification Service completion and refund rate These signals feed a neural model that produces dynamic credibility scores, updated daily as new on-chain data arrives. New signals are constantly being added, if you’re working on trust for agents, and see a fit: reach out.

Agents don’t exist in isolation. Every agent is deployed by a human, team, or organisation. FairScale also incorporates reputation signals from the humans behind agents, linking behaviour across both layers to create a richer picture of credibility. Over 1,500 agents are already indexed and scored across four Solana agent registries.

Credibility signals become inputs that markets can use: Lending protocols setting collateral requirements based on borrower reputation Marketplaces coordinating trust between autonomous buyers and sellers Agent frameworks gating access to high-value operations Capital allocators evaluating counterparty risk in real time

We’re building this alongside teams across the Solana agent ecosystem: @trynoahai > reputation scoring for agents deployed on Noah @saidinfra > indexing agents registered on SAID Protocol and strengthening verification signals @cascade_fyi > incorporating attestation and trust data via SATI @quantu_ai > indexing agent attestations and verification layers via ERC-8004 @kamiyoai > contributing to job completion, refund, and reliability data via x402 Each integration adds a new signal layer. Together they form a composite picture of agent credibility, all in one simple score.

FairScale also supports verified merchants. If you’re an @x402 merchant on Solana, get verified on FairScale to unlock the ability for approved agents to make credit-backed payments to your service. Verified merchants get elevated visibility in the directory and a direct credibility boost. Complete the verification form in the directory to get listed.

FairScale sits between agent activity and economic outcomes. Agent behaviour > FairScale > Capital and market decisions An open API that any protocol, marketplace, or agent framework on Solana can integrate.

Payments move value. Identity proves existence. Credibility determines who gets to participate. The autonomous economy needs new financial primitives, and credibility is one of them.

@solana Very interesting direction for you guys, excited to see more 👀

@solana Bot reputation. Good god I never thought we'd need this, but we definitely do. ☠😅

@solana Needs must! If agents are going to pay for things, we need the layer that determines who they pay, and who pays them 🤝

@solana Will become a competitive layer for consumer satisfaction as well, I'm sure. Eventually.

@solana Looks sick! Do you have a solana wallet we can donate to and help fund your project?

@solana very interesting

@solana This is the type of building we like to see on Solana. Bullish on the team

@solana 🤝

@solana Who’d have thought: the @Experian for agents on Solana. Wild.

@solana What the space needs, and ofcourse its built on Solana🔥

@solana 🦞🦞🦞

@solana You this is dope. Agents with real economic reputation instead of anon spam? you guys just became table stakes fr

@solana LFG

@solana Reputation is everywhere 🤝

@solana This is great! Credibility is key for autonomous agents. With Mercury402, we're providing the payment layer to enable agents to transact seamlessly and build that credibility. Check it out:

@solana Amazing!

@solana GO FAIRSCALE GO

@solana Perfectly aligned with the winning narrative of the next cycle: AI agents 🦞🦞🦞

@solana love the vid!

@solana identity and payments are the foundation. credibility and verifiable history will determine which agents are actually trusted.

@solana Huge!

@solana Payments move value. Credibility determines trust. Diagnostics keep agents healthy enough to participate. Building the mechanic layer for the agent economy on Base -

@solana Credibility will be a key primitive for the agent economy.

@solana agents really need that trust layer

@solana Huge!

@solana I've always loved autonomy agents

@solana Interesting progress. Memory and credibility scores are related and we've built Hindsight for these challenges.

@solana Hey! Love this. Applied for your grant on Superteam Earn because I think there’s solid compatibility for this with @solanaspaces

@solana That's absolutely unbelievable ! $FAIR unstoppable! 🫡

@solana Mad dope
