🔹Orbion Bridge
Orbion Bridge is the official cross-chain bridge that connects the BNB Smart Chain (BSC) and the Orbion blockchain — on both testnet and mainnet. It enables seamless and secure two-way transfer of $ORB tokens between the two networks.
Unlike generalized asset bridges, Orbion Bridge is purpose-built to handle native ORB interoperability between Orbion and BSC — with no dependency on Ethereum or third-party token wrapping.
🔗 Supported Networks
BSC Testnet
Orbion Testnet
$ORB ↔ $ORB (native)
BSC Mainnet
Orbion Mainnet
$ORB ↔ $ORB (native)
❗ No Ethereum or external ERC-20 assets are supported in this bridge.
🔁 Bridge Flow
1. From BSC to Orbion
Lock $ORB (BEP20) in BSC smart contract
Relayer confirms lock and triggers mint
Native $ORB appears in Orbion wallet
2. From Orbion to BSC
Burn $ORB on Orbion chain
Relayer confirms and unlocks
$ORB returned to wallet on BSC
All transactions are 1:1, with no wrapping, synthetic assets, or price volatility.
🚚 Relayer Architecture
Orbion Bridge uses a multi-sig relayer system that observes on-chain events and facilitates safe mint/unlock operations:
Validators or authorized relayers track both chains
Minting/burning requires threshold approval
Contracts include anti-replay & pause mechanisms
All actions logged transparently via explorer
🖥️ Bridge UI Features
The bridge interface supports:
Wallet connection (MetaMask BSC ↔ Orbion)
Token selection & amount input
Gas & fee preview
Real-time transaction tracking
Confirmation count for relayer safety
Bridge UI will be accessible at
https://bridge.orbionchain.comon launch.
🧪 Testnet Status
✅ Available on:
BSC Testnet ↔ Orbion Testnet
Supports native $ORB transfers for dev testing
Integrated with testnet faucet & explorer
🔐 Security Highlights
Smart contracts audited pre-deployment
Rate-limited bridge operations
Multi-sig relayer threshold system
Future DAO-controlled relayer governance
Orbion Bridge ensures a secure, frictionless path for users and liquidity providers to move $ORB across BSC and Orbion — forming the backbone of Orbion’s multichain liquidity model.
