Transfers a cross-chain message.

Transfers tokens/assets between multiple blockchain networks using Hyperlane's cross-chain infrastructure.

FUNCTIONALITY: • Moves tokens from one blockchain to another (e.g., USDC from Ethereum to Polygon) • Supports sequential transfers across multiple chains in a single operation • Handles various token types including native tokens, ERC20 tokens, and synthetic tokens

PREREQUISITES: • A warp route must exist for the specified token symbol and chain combination • If no warp route exists, deploy one first using the deploy-warp-route tool • Sufficient token balance on the origin chain • Sufficient gas tokens on all involved chains for transaction fees

PARAMETERS: • symbol: The token identifier (e.g., "USDC", "ETH", "WBTC") • chains: Array of blockchain names in transfer order (e.g., ["ethereum", "polygon", "arbitrum"]) • amount: Token amount in wei or smallest token units (e.g., "1000000" for 1 USDC with 6 decimals) • recipient: Destination wallet address (defaults to sender if not specified)

OUTPUT: • Returns transaction hashes and message IDs for each cross-chain transfer • Each transfer between adjacent chains generates one transaction • Use message IDs to track delivery status across chains

EXAMPLE USE CASES: • Bridge USDC from Ethereum to Polygon • Multi-hop transfer: ETH from Ethereum → Arbitrum → Base • Cross-chain token arbitrage or yield farming

Deploys a warp route.

Deploys a new chain to the Hyperlane network.

Runs a validator for a specific chain.
