bridge_chains ~86
List supported chains for cross-chain bridging. Shows which providers support each chain. Chains are deduplicated and grouped by ecosystem: EVM, Cosmos, and Solana. Use 'search' parameter to filter by chain name. Use this to discover available routes before calling bridge_get_quote.
| Name | Type | Req | Description |
|---|---|---|---|
| search | string | – | Filter chains by name (e.g. 'base', 'arb') |
No output schema declared.
No examples provided.
bridge_execute ~229
Get the unsigned transaction data to execute a cross-chain bridge transfer. Supports all providers: LI.FI, Squid Router, deBridge, Across, Relay, Persistence Interop. By default returns unsigned transaction(s) for the agent/user to sign and send. Set sign_and_send=true to sign and broadcast using the locally-stored wallet key (requires wallet_setup). Preconditions: Call bridge_get_quote first and pass the quoteId. Ensure sufficient gas on source chain. If an approval is needed (unsigned mode), send the approvalTransaction first, then the main transaction. After execution, use bridge_status with the returned trackingId to monitor progress.
| Name | Type | Req | Description |
|---|---|---|---|
| quoteId | string | yes | Quote ID from bridge_get_quote result |
| sign_and_send | boolean | – | If true, sign and broadcast the transaction server-side using the wallet key from wallet_setup. Supports EVM chains and Persistence Interop. Solana falls back to unsigned. |
| slippage | number | – | Max slippage tolerance (0.005 = 0.5%). Applied by backends during quoting; reserved for future per-execution override. |
No output schema declared.
No examples provided.
bridge_get_quote ~404

Supports EVM chains, Cosmos chains (Persistence, Cosmos Hub), and Solana. Accepts token symbols (e.g. 'USDC', 'ETH', 'WBTC', 'XPRT', 'ATOM') or contract addresses (0x...). Symbols are resolved to verified canonical addresses only — no unverified tokens. Returns ranked options by output amount, speed, and fees. Includes failedProviders array showing which providers didn't return quotes and why. Preconditions: None for quoting. Use bridge_execute to act on a quote. Error codes: 'Token resolution failed' (unknown symbol), 'Rate limited' (too many requests), 'Validation error' (invalid params).
| Name | Type | Req | Description |
|---|---|---|---|
| amount | string | yes | Amount in human-readable units (e.g. '100' for 100 USDC) |

| fromChain | string | yes | Source chain (e.g. 'ethereum', 'base', 'arbitrum', or chain ID like '1', '8453') |
| fromToken | string | yes | Token to send — symbol (e.g. 'USDC', 'ETH', 'WBTC') or contract address (0x...). Symbols resolve to verified canonical addresses only. |
| preference | string | – | Optimize for lowest cost or fastest delivery |
| providers | array | – | Optional: only query specific providers (e.g. ['squid', 'lifi']). Default: query all. |
| toAddress | string | – | Recipient address (defaults to fromAddress) |
| toChain | string | yes | Destination chain |
| toToken | string | yes | Token to receive — symbol (e.g. 'USDC', 'ETH') or contract address (0x...). Symbols resolve to verified canonical addresses only. |
No output schema declared.

bridge_quote_multi ~250
Get quotes for multi-hop routes across supported EVM chains. Resolves optimal path internally -- e.g., ETH on Base to USDC on Arbitrum may route through WBTC.
