What is Clavion?
Clavion (ISCL — Independent Secure Crypto Layer) is a local runtime that lets AI agents sign Ethereum transactions without ever touching private keys. It sits between your agent framework and the blockchain, enforcing policy checks, risk scoring, and human approval before any funds move.Why Clavion exists
AI agents need to perform crypto operations: token transfers, DEX swaps, spending approvals. Existing approaches all fail:- Agent holds keys directly — one prompt injection drains the wallet
- Hardware wallet — requires physical interaction, incompatible with autonomous workflows
- Custodial API — counterparty risk, not self-custody
- TEE / secure enclave — hardware-dependent, doesn’t solve policy or approval
