LayerHop tools (15, 3 write)

write = sends, deletes, buys or posts
  • build_transactionFree

    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_deposit_addresswrite actionFree

    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.

  • disable_deposit_addressFree

    Disable a deposit address: LayerHop stops tracking it (no more orders or webhooks for it). The provider may still process funds sent to it later, so the user must stop using it. Cannot be undone. Confirm with the user first. Needs a LayerHop API key.

  • get_deposit_addressFree

    Get one deposit address with its 20 most recent deposits (orders, quoteId starting with dep_): amount deposited and delivered, status (submitted, pending, filled, refunded, failed) and tx hashes. 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. Read-only.

  • get_order_statuswrite actionFree

    Check the status of a swap or bridge after the source transaction was sent: pending, filled (funds delivered), refunded, failed, or unknown (some same-chain providers; check the tx on an explorer). Read-only.

  • get_quoteFree

    Get the best price to swap or bridge tokens, within one chain or across chains (EVM <-> Solana). Asks every liquidity provider and returns the best quote plus alternatives with human-readable amounts, minimum received after slippage, fees (LayerHop fee, partner fee, provider fee, gas) and ETA. Returns a quoteId (valid until expiresAt) and a layerhop.com swapLink a human can open to review and sign. Read-only: The LayerHop MCP server holds no private keys and never signs or broadcasts transactions. Always show the user the fees and output and get confirmation before proceeding.

  • get_swap_linkwrite actionFree

    Create a https://layerhop.com/swap link prefilled with the swap, which the user opens to review the live quote and fees and sign in their own wallet. This is the default, safest way to execute a swap. The LayerHop MCP server holds no private keys and never signs or broadcasts transactions. The amount is in human units.

  • list_chainsFree

    List every blockchain LayerHop can swap from or to: slug, numeric chain id, name, VM type (evm or svm = Solana) and native coin. Read-only.

  • list_deposit_addressesFree

    List the deposit addresses of the API key's account and mode (live or test), newest first: address, route, status, deposit count. Needs a LayerHop API key. Read-only.

  • list_ordersFree

    List LayerHop orders (swaps built or submitted through LayerHop) where the address is the sender or recipient, newest first, with status. Public data (addresses only). Read-only.

  • list_tokensFree

    List LayerHop's built-in tokens on one chain (symbol, contract address or mint, decimals). Symbols can be used directly in get_quote; other tokens can be quoted by address. Read-only.

  • refresh_deposit_addressFree

    Ask LayerHop to check a deposit address for new deposits right away (instead of waiting for the next scheduled check). Call it when the user says they sent funds, then call get_deposit_address after ~15-30 s. Needs a LayerHop API key.

  • report_submittedFree

    Tell LayerHop that the user's wallet broadcast the transaction for a quoteId, so the order is tracked (status, webhooks). Call this once after broadcasting, with the EVM tx hash (0x + 64 hex) or Solana signature. Idempotent. Does not sign or send anything.

  • simulate_depositFree

    TEST MODE ONLY (lh_test_ key and a test deposit address): record a fake deposit so the integration can be tested end to end; it becomes a test order that settles with webhooks. The amount decides the outcome: base units ending in 4001 -> refunded, 4002 -> failed, anything else -> filled. Moves no real funds. Fails with a live key.

  • simulate_transactionFree

    Build the transaction for a quoteId and dry-run it on-chain (EVM eth_call + gas estimate from the sender; Solana simulateTransaction) without sending anything or recording an order. Reports whether it would succeed, gas / compute units, whether an ERC-20 approval is still needed, and the error if it would fail. Read-only: The LayerHop MCP server holds no private keys and never signs or broadcasts transactions.

LayerHop JavaScript SDKs

TypeScript/JavaScript packages for LayerHop: best-price cross-chain and same-chain swaps across EVM chains and Solana through one non-custodial API. Nothing here holds keys or signs; you get quotes and unsigned transactions that your users' wallets sign.

Docs:

Packages

packages/shared is an internal, private package (chain registry, tokens, error codes, types). It is inlined into each published package at build time, so you never install it.

Quickstarts

SDK (npm install @layerhop/sdk)

import { LayerHop } from "@layerhop/sdk";

const lh = new LayerHop({ integrator: "myapp" });
const { best } = await lh.quote({
  srcChain: "base", srcToken: "USDC", amount: "100000000", // 100 USDC, base units
  dstChain: "solana", dstToken: "SOL",
  sender: "0xYourEvmAddress", recipient: "YourSolanaAddress",
});
const tx = await lh.buildTx(best.quoteId); // unsigned; sign with your wallet

Checkout: pay with any token (@layerhop/sdk 0.2+)

const session = await lh.checkout.create({
  amount: "49000000", settleChain: "base", settleToken: "USDC", // 49 USDC on Base
  recipient: "0xYourPayoutAddress", successUrl: "https://shop.example.com/thanks",
});
// Send the customer to session.url; fulfil on the checkout.session.completed webhook.
