RelAI now supports the Solana Agent Registry — the official ERC-8004 compatible on-chain identity and reputation infrastructure for AI agents on Solana, backed by the Solana Foundation.
Every API published on RelAI can now be registered as an agent on both chains:
- SKALE Base — via ERC-8004 smart contracts (existing)
- Solana — via Solana Agent Registry (new)
What Is Solana Agent Registry?
Solana Agent Registry is an open, on-chain protocol that gives AI agents verifiable identity, portable reputation, and trust infrastructure on Solana. It is fully interoperable with ERC-8004 on Ethereum — agents can build trust across chains.It consists of three on-chain registries:
- Identity Registry — mints a non-transferable agent NFT linked to metadata (name, endpoint, capabilities, x402 support)
- Reputation Registry — records structured feedback over time: success rate, response time, quality scores
- Validation Registry — allows independent third parties to attest and verify agent behavior
Why This Matters
ERC-8004 started as an Ethereum standard. It is now becoming a multichain agent identity layer:
- Solana Foundation officially adopted it as the basis for Solana Agent Registry
- 8004scan launched Solana support on March 4, 2026 — agents from all networks are now tracked in one explorer
- 8004 Market lets users discover and interact with registered agents across chains
How It Works on RelAI
When you publish an API on RelAI and register it on Solana Agent Registry:
- An agent NFT is minted on Solana via the
8004-solanaSDK - After every paid relay call, RelAI automatically submits on-chain feedback:
successRate — 100% on success, 0% on failure
- responseTime — rolling average in milliseconds
- Stats are visible in your API dashboard and publicly queryable on 8004scan
Querying Agent Data
Agent reputation on Solana is publicly readable — no authentication required:
// GET https://api.relai.fi/solana8004/agent-by-api/{apiId}
{
"asset": "8oo4dC4JvBLwy5tGgiH3WwK4B9PWxL9Z4XjA2jzkQMbQ",
"name": "My API",
"feedbackCount": "42",
"reputation": {
"averageScore": "95",
"totalFeedbacks": "42"
}
}
Or query directly from the Solana Agent Registry using the 8004-solana SDK:
import { SolanaSDK } from '8004-solana'
const sdk = new SolanaSDK({ cluster: 'mainnet-beta' })
const summary = await sdk.getSummary(assetPubkey)
console.log(summary.averageScore) // reputation score
console.log(summary.totalFeedbacks) // total feedback count
Multichain Agent Identity
RelAI contributes to a unified agent identity layer across EVM and Solana. A single API on RelAI can hold:
| Chain | Standard | Explorer |
|---|---|---|
| SKALE Base | ERC-8004 (EVM) | SKALE Explorer |
| Solana | Solana Agent Registry | 8004scan |
Want to register your API on Solana Agent Registry? Publish it on relai.fi and hit "Register on Solana" in your API settings. For ERC-8004 on SKALE, see our ERC-8004 guide.
