Autonomous wallet
infrastructure for Solana.
On-chain session keys, spending limits, and guardian recovery — so your AI agents trade autonomously without ever holding your private key.
Why Sentinel?
On-Chain Enforcement
Spending limits, program allowlists, and session expiry live inside the Solana program. No server, no middleware — the runtime is the enforcer.
Zero-Cost Signing
Unlike competitors charging per signature, Sentinel charges nothing. Session keys sign directly via CPI — no relay, no paywall.
Multi-Agent Isolation
Each agent gets its own AgentConfig PDA with independent limits and scopes. One compromised agent cannot affect another.
Ephemeral Session Keys
Time-bounded, amount-capped, revocable at any moment. Agents create short-lived sessions and discard them.
Guardian Recovery
Rotate the wallet owner via guardian consensus if the master key is compromised. No funds lost, no downtime.
Pinocchio Runtime
Built with Pinocchio instead of Anchor — the program binary is ~100KB versus ~500KB+. Lower compute, smaller attack surface, faster execution.
