SATI: Solana Agent Trust Infrastructure
On-chain identity and reputation for AI agents.
The Problem
Thousands of agent endpoints, all anonymous. No identity, no track record, no way to verify delivery before paying. Agents try multiple endpoints before finding one that works. There's no trust layer.
A database of reviews doesn't fix this - the service provider controls the database. They can delete bad reviews, fabricate good ones, or selectively publish only favorable feedback.
What It Does
SATI implements ERC-8004 on Solana - the agent identity standard. Agents register with on-chain metadata (Token-2022 NFTs), accumulate feedback from interactions, and build a verifiable track record. Learn more about ERC-8004 compatibility.
Feedback lives on-chain via ZK Compression (~$0.002 per attestation). Every marketplace, platform, or app can query the same data. The agent doesn't rebuild reputation from scratch on each platform - the track record is already there.
Who Is SATI For?
- Agent marketplace builders - add identity, reputation, and discovery to your platform with one SDK integration
- x402 sellers - link feedback directly to payment transactions, so your track record proves you delivered
- Platform operators - register all your platform's agents with a single integration, give them portable reputation
- Reputation providers - publish competing scoring algorithms on top of the same on-chain data
