Cross-chain asset bridge with MPC threshold signing across major external networks. LP-333 signer set management with 100M LUX slashable bonds.
The Bridge Chain connects Lux Network to major external blockchains through MPC threshold signing. Unlike centralized bridges, the B-Chain distributes signing authority across a decentralized set of validators with 100M LUX in slashable bonds (LP-333).
Bridge operations are verified by multiple independent parties before execution. The threshold signing scheme means no single party can move funds — a configurable quorum must agree on every cross-chain transfer.
Supported networks include Ethereum, Bitcoin, Solana, Cosmos, Polkadot, and others. New chains can be added through governance proposals without protocol upgrades.
Quick start using the Lux JavaScript SDK.
import { BridgeClient } from 'luxnet/bridge'
const bridge = new BridgeClient('https://bridge.lux.network')
// Bridge ETH from Ethereum to Lux
const tx = await bridge.transfer({
sourceChain: 'ethereum',
destChain: 'lux-c',
asset: 'ETH',
amount: '1.5',
recipient: '0x...',
})
