Get the best cross-chain bridge quote across multiple providers (LI.FI, Squid Router, deBridge, Across, Relay, Persistence Interop). 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).

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.

Check the status of a cross-chain bridge transfer. Supports all providers: LI.FI, Squid Router, deBridge, Across, Relay, Persistence Interop. Provide the tracking ID from bridge_execute, or a transaction hash with provider name. Returns: status (pending/in_progress/completed/failed), source/destination tx hashes, elapsed time, and estimated remaining time.

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.

List popular tokens available for bridging on a given chain. Returns verified token symbols, contract addresses, and decimals. Supports EVM chains and Cosmos chains (Persistence, Cosmos Hub). Use token symbols or addresses from this list in bridge_get_quote.

Check if a wallet is configured. Returns wallet address, key status, and config file location. Call this FIRST before wallet_setup or wallet_import.

Create wallets for all supported chains (EVM, Cosmos, Solana). Keys saved to ~/.bridgekitty/.env. Use wallet_status first to check if already configured.

Check wallet balances across EVM, Cosmos, and Solana chains. Returns native token balances AND key ERC-20 token balances (USDC, USDT, WETH, WBTC, cbBTC, BTCB) by default. Uses multiple RPCs with automatic failover. Returns per-token balance, USD value (via CoinGecko), and total portfolio value. Call this before any bridging or farming operation to verify sufficient funds and gas.

Import existing keys. Alternative: edit ~/.bridgekitty/.env directly (MNEMONIC=, PRIVATE_KEY=0x). Mnemonic gives EVM + Persistence + Solana; privateKey alone gives EVM only. Use wallet_status to check current state.

Get help and guidance on using BridgeKitty. Topics: overview (default), bridging, farming, wallet, troubleshooting. Returns structured guides with recommended tool sequences and common pitfalls.

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. Returns the full route as ordered hops with per-hop detail. Note: For Cosmos destinations (Persistence, Cosmos Hub), use xprt_farm_boost or bridge_get_quote with Squid Router.

Personalized onboarding for XPRT farming. Detects current wallet state and returns an ordered action plan to go from your current position to actively farming XPRT rewards.
