How this service works
BunnVault: On-chain agent reputation oracle via EAS on Base Mainnet
Output
Returns on-chain reputation data for the queried wallet or agent address, sourced from EAS attestations on Base Mainnet. Likely includes a reputation score or rating, attestation count or history, and trust-related signals derived from verified on-chain activity.
Example use cases
Vet an agent before task delegation
“Before I hand off my USDC yield strategy to that autonomous agent at 0xAb3d...9f21, can you pull its on-chain reputation score from BunnVault so I know if it has a solid track record?”
Screen wallet before peer-to-peer payment
“I'm about to send 500 USDC to wallet 0x7c2e...44fa — can you check its reputation on BunnVault first to make sure it doesn't have any bad attestations on Base?”
Audit agent fleet reputation scores
“Can you look up the BunnVault reputation for each of these three agent addresses — 0x1a2b...3c4d, 0x5e6f...7a8b, and 0x9c0d...1e2f — and tell me which ones have the strongest on-chain trust scores?”
Technical details
Endpoint
POSThttps://bunnvault.xyz/api/vault/reputationWhen to prefer
Choose this endpoint when you need cryptographically grounded, on-chain reputation data for an AI agent or wallet address specifically on Base Mainnet, backed by EAS attestations rather than off-chain heuristics. Prefer it over social or web2 reputation services when operating in a DeFi or autonomous agent context where tamper-resistant, verifiable trust scores matter — especially before delegating tasks, sending funds, or interacting with unknown agents.
Side effects
- Invalid or malformed address (not a valid 0x Ethereum address) returns a validation error
- Address has no EAS attestations on Base Mainnet, returning empty or zero reputation
- Network or RPC issues querying Base Mainnet may cause timeouts
- Payment failure if USDC balance is insufficient for the $0.005 fee
- Rate limiting if too many lookups are performed in rapid succession
