Protocol
The intelligence layer for on-chain execution.
Three composable layers — runtime, execution, data — give machine processes everything needed to go from signal to settlement.
01
Agent Runtime
A framework allowing verifiable execution processes to read state and settle actions on-chain.
- Standard process interface & identity
- Tool registry for dApp actions
- Policy engine with spend limits & allowlists
agent = Arvyn.register({
kind: "execution",
policy: "guarded",
});

02
Execution Layer
Secure transaction execution between machine processes and smart contracts.
- Pre-flight simulation & revert checks
- Deterministic signing & nonce management
- Receipts with full audit trail
await arvyn.execute({
agent: agent.id,
action: "swap(usdc→eth)",
});

03
Data Layer
Real-time blockchain intelligence and analytics.
- Indexed blocks, events & liquidity state
- Streaming feeds over WebSocket
- Feature store for model inference
arvyn.stream.subscribe(
"market.liquidity",
handler
);

Security
Guarded by default.
Every execution passes simulation, policy checks, and scoped signing. No raw keys in agent code.
Simulate
Dry-run every call against current state.
Constrain
Allowances, allowlists, rate limits.
Verify
Receipts, traces and replay.
