How Execution Works

Syenite never holds private keys. swap.quote returns an unsigned transactionRequest with optimal route calldata. The agent or user signs and submits from their own wallet. For cross-chain bridges, use swap.status to track delivery.

Supported Chains

Swap/Bridge: Ethereum, Arbitrum, Base, Optimism, Polygon, BNB Chain, Avalanche, zkSync, Linea, Scroll, and 20+ more.

Lending data: Ethereum, Arbitrum, Base, BNB Chain.

Protocols: Aave v3, Morpho Blue, Spark, Compound V3, Fluid, Venus.

Access

Open access — no API key required. Rate limited to 30 req/min per IP.
