Build the unsigned transaction for a quote
build_transaction
Turn a quoteId from get_quote into the UNSIGNED transaction the user's own wallet must sign: EVM {chainId, to, data, value in wei, optional ERC-20 approval to send first} or Solana {serializedTx base64}. Includes plain-language signing steps. The LayerHop MCP server holds no private keys and never signs or broadcasts transactions. Only use this when the user has their own signer and explicitly wants raw transaction data, after they confirmed the quote; otherwise give them the swap link.

Create a deposit address
create_deposit_address
Create an address the user sends tokens to; every deposit is swapped/bridged and delivered as toToken on toChain to recipient. No wallet connection or signing needed. Non-custodial: the address belongs to the liquidity provider (Relay), LayerHop never holds funds. Tell the user: send ONLY srcToken on srcChain to the address (other tokens or chains may be lost for good), at least $1 worth; refundTo must be the user's own address on srcChain, never an exchange (CEX) deposit address. Needs a LayerHop API key; test keys (lh_test_) give a fake sandbox address that must never receive real funds. The LayerHop MCP server holds no private keys and never signs or broadcasts transactions.
