Skip API

Overview

The Skip API is a powerful tool designed to facilitate seamless cross-chain transactions, allowing users to perform asset transfers efficiently across different blockchain networks. This document provides detailed instructions and examples on how to leverage the Skip API to enhance cross-chain functionalities within the Initia ecosystem.

API and Reference Materials

API Documentation: Available at Skip API Documentation.
Implementation Reference: Visit https://ibc.fun/ for practical implementations and additional context.

Available Functions

Currently, the API supports the transferring of assets. Swapping assets will be introduced in the future, coinciding with the addition of Initia DEX as a swap venue.
