ThunderCore Bridge

Intro

The ThunderCore bridge allows user to transfer assets between two chains in the ThunderCore ecosystem. ThunderCore bridge is a customized version of POA network bridge.

Chain and Network Definitions

A bridge is created between 2 networks, referred to as a Native (or Home) Network and a Foreign Network.
  • Home: A network with fast and inexpensive operations. All bridge operations to collect validator confirmations are performed on this side of the bridge, always refers to ThunderCore.
  • Foreign: Can be one of Etheruem/BSC/HECO
  • ERC20: Refers to an ERC20 token created during the bridge process. In the ERC20-ERC20 bridge, ERC677 represent ERC20 tokens on one side of the bridge and are minted and burned accordingly.

Bridge Components

A bridge is created between two networks, referred to as a Native (or Home) Network and Foreign Network.
  • Token bridge: Listens to events and sends transactions to authorize asset transfers. Bridge UI Application: A DApp GUI to transfer tokens and coins between chains.
  • Bridge UI Application. A DApp GUI to transfer tokens and coins between chains.
  • Bridge smart contracts: Manages bridge validators, collects signatures, and confirms assets relay and disposal. Located at: https://github.com/thundercore/thunder_bridge

Production Asset-transfer Bridges

The following bridges are fully functional in ThunderCore's production environments:
Ethereum (Bridge between ThunderCore mainnet and Ethereum mainnet): Cost effective
Kovan (Bridge between Thundercore testnet and Kovan)
BSC (Bridge between ThunderCore mainnet and BSC Network): A bridge service providing access to inter-blockchain liquidity for Binance Chain and Binance Smart Chain decentralized applications.
BSC testnet (Bridge between ThunderCore testnet and BSC testnet)
HECO (Bridge between ThunderCore mainnet and HECO Network): A decentralized and cost-efficient public chain that Ethereum developers can easily get started with, in which smart contracts are seamlessly compatible.
HECO testnet (Bridge between ThunderCore testnet and HECO testnet)
