Client Library

​

v1.6.0

​

Enhancements

• CCTP v2 Support: Added support for CCTP v2 transfers and the CCTP relayed flow (v1.6.0–v1.6.4).
• Transaction Status Fix: cctp_transfer_v2 entries in transaction status responses are now handled correctly. Previously they fell through the transfer-type checks, leaving the event without a type, chain IDs, or explorer links, and reporting a failed status while the transfer was still pending.
• Removed Lombard Ledger mainnet and testnet chain configuration.

​

v1.5.1 – v1.5.18

​

Enhancements

• getRouteWithGasOnReceive helper: Added a higher-level helper that builds the main and gas routes for Gas on Receive (complements executeMultipleRoutes).
• Cosmos MEVM support.
• Affiliate fees: Fixed passing affiliates to the widget/client library via setClientOptions.
• Explorer links: Added timeout-tx explorer links for timed-out IBC transfers, and fixed Axelar explorer links.
• Cleanup: Removed the legacy gas-station logic.

​

v1.5.0

​

Major Features

• Gas on Receive Support: Added executeMultipleRoutes function that enables simultaneous execution of multiple routes. This powers the gas on receive feature, allowing users to automatically receive native gas tokens on destination chains during cross-chain swaps. The function accepts multiple routes (e.g., main swap + gas fee route) and executes them in a shared transaction for Cosmos chains. Learn more about Gas on Receive.

​

v1.1.9

​

Enhancements

• Batch Transaction Signing: Added batchSignTxs parameter to executeRoute. When enabled (default: true), all transactions in a multi-transaction route are signed upfront before broadcasting, reducing the number of user prompts and improving the overall user experience.

​

v1.1.0

​

Enhancements

• Transaction Timestamps: The ChainTransaction type now includes an on_chain_ts field, providing a timestamp for when the transaction was confirmed on-chain. This can be useful for tracking and display purposes.
• Exported JSON Types: Relevant JSON types used by the client are now exported, improving the developer experience for those working directly with these underlying types.

​

v1.0.0

​

Key Changes:

• Improved Tree-Shaking: The client library has been refactored to export separate functions instead of a single class. This allows for better tree-shaking, reducing the impact on your application’s bundle size.
• Consistent Naming Conventions: All properties and variables now strictly follow camelCase (and PascalCase for enums). This change facilitates the auto-generation of interfaces based on the OpenAPI spec (swagger.yml) and simplifies the conversion between camelCase and snake_case for API consumption.

​

v0.10.3

• The executeRoute method now accepts beforeMsg and afterMsg parameter to allow for the execution of custom Cosmos messages before/after the route is executed. This is useful for executing custom messages that are not part of the route definition.

// An example of how to use the `beforeMsg` parameter with a MsgSend
const msg = JSON.stringify({
  fromAddress: 'cosmos1...',  // Replace with sender address
  toAddress: 'cosmos1...',    // Replace with recipient address
  amount: [{
    denom: 'uatom',           // Replace with the actual denom, e.g., 'uatom' for ATOM
    amount: '1000000'         // Replace with the actual amount (in smallest unit, e.g., micro-ATOM)
  }]
});

await skip.executeRoute({
  route,
  userAddresses,
  beforeMsg: { msg, msgTypeURL: '/cosmos.bank.v1beta1.MsgSend' }
});

​

v0.9.3

• Update client to include solana support via public RPC and show warning when public infrastructure is not overriden.

​

v0.9.0

• Add /balance methods query API endpoint. See the documentation and the API reference for more details.
