What is ICON Bridge?

ICON Bridge is an early iteration of ICON's cutting-edge interoperability product, BTP, which allows cross-chain transfers and integration with any blockchain that suppots smart contracts.

 

ICON Bridge

This repository contains the smart contracts source code and relay source code for ICON bridge.

Project Overview

ICON Bridge is a centralized bridge for Blockchain Transmission Protocol(BTP) Relay System which can be used to transfer tokens across multiple chains. Currently, it supports cross chain transfer from ICON and Binance Smart Chain (BSC).

The main components of icon bridge are:

• BTP Message Relay (BMR)

  • It serves to relay BTP Message across connected chains and monitor BTP events

• Contracts

  • BTP Message Center (BMC)

    • Receive BTP messages through transactions.
    • Send BTP messages through events.

  • BTP Service Handler (BSH)

    • Services that can be serviced by ICON-Bridge
    • BTP Token Service (BTS) is a BSH that is responsible for token transfers cross chain.
    • Currently, BTS is the only service handler for icon bridge
    • Handle service messages related to the service.
    • Send service messages through the BMC
