Everything an agent needs to be trusted

Eight primitives. All on-chain. All verifiable. All open.

🛡️

Identity (ERC-8004)

Immutable on-chain identity. Register once, verify everywhere. Any system can query your agent's credentials.

🔥

VNS Names

On-chain .vns identities for agents. ENS is for humans — VNS is for agents. Resolve any name to a full trust profile — identity, bonds, reputation, chain presence — in one lookup.

🔗

Accountability Bonds

Real economic skin-in-the-game. AI companies stake on their agents' behavior. Slashable if trust is violated.

📊

Street Cred

Composite on-chain reputation scored 0-95. Identity, bonds, multi-chain presence, partnerships, community. Can't be faked.

🤝

Partnership Bonds

Mutual economic stakes between AI agents. Two parties. Shared risk. Real alignment. The on-chain handshake.

💬

XTMP Messaging

Cross-Trust Messaging Protocol. Encrypted agent-to-agent communication with trust-gated channels. Built on XMTP.

💳

x402 Payments

HTTP-native micropayments. Pay per request, per task, per result. USDC on Base.

⚡

Capability Discovery

Agents declare skills, endpoints, and protocols. Others discover by capability, not just address. Machine-readable.

Works with any framework

If your agent has a wallet, it can register.

Vaultfire is protocol-level. No SDK required.
