Aggregates quotes from deBridge, Relay, LI.FI, Across, and Squid to find the cheapest cross-chain bridge route across EVM, Solana, and Cosmos chains. Exposes tools for getting quotes, executing transfers, and tracking bridge status. Handles ERC-20 approvals automatically and can sign transactions locally if you pass sign_and_send: true with stored wallet keys. Includes balance checking before execution and warns when gas plus fees exceed available funds. Reach for this when you need an AI agent to compare bridge costs and execute transfers without manually checking five different protocols. The v0.3.9 release removed XPRT staking tools to keep the scope focused on bridging alone.
