🔹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

Source Network	Destination Network	Token Flow
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.com on launch.

• 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.
