What is Orbiter Finance?
Orbiter Finance is a decentralized bridge that uses ZK technology to optimize interoperability between Layer 2 networks in the Ethereum ecosystem. Unlike traditional bridges that rely on lock & Mint mechanisms, Orbiter enables users to transfer native assets between Ethereum and dozens of Layer 2 networks quickly, cheaply, and securely. With a focus on zero-knowledge (ZK) technology, the project aims to simplify the cross-rollup asset transfer experience , while building the infrastructure for a multi- chain future.
How does Orbiter Finance work?
Orbiter Finance uses the Sender – Maker – Dealer model instead of the traditional smart contract mechanism:
- Sender : user initiates transaction, sending assets to Maker's EOA.
- Maker : provides liquidation on both source and destination networks, performing manual or automated asset transfers.
- Dealer : decentralized frontend interface, integrated with Orbiter protocol for easy user interaction.
Arbitration – Smart arbitration mechanism
In the event of a failed transaction or dispute, the Sender can initiate an arbitration process through smart contracts and zero-knowledge proofs (ZKPs) to reclaim assets and receive compensation. The three technical components supporting this process include:
- MDC (Maker Deposit Contract): holds Maker's deposit.
- EBC (Event Binding Contract): synchronize transaction data.
- ZK-SPV : verify cross-rollup transactions transparently and decentralized.
Products in the Orbiter Finance ecosystem

- V2 : advanced support such as Token conversion, different source wallet – destination wallet, cross- Token…
2. zkProver
- ZK proof system helps optimize gas fee , supports Account Abstraction (AA), compatible with EIP-4337.
- Gas Price can be reduced by up to 30% for ERC20 transactions when using the zk-SNARK batch mechanism.
3. Inscription Cross-Rollup Protocol
- Support Mint and transferring Inscriptions between L2 networks (zkSync, Arbitrum, Linea, Scroll…).

OBT Airdrop Program Details
Orbiter Finance deploys OBT Token Airdrop for early adopters and ecosystem contributors using O-Points mechanism:
Conditions for receiving Airdrop
- Using Orbiter from December 2021.
- Accumulate at least 40 O-Points , maximum is 5,000 O-Points .
- Whitelist : Discord moderators , Non-Fungible Token holder (Ace/Expert) , offline event participants .
How to calculate OBT from O-Points
- Users will be able to convert O-Points into OBT at a pre-calculated rate.
- Ace Non-Fungible Token Holder receive up to 17,000 OBT/ Non-Fungible Token .
- Expert Non-Fungible Token Holder receive 2,300 OBT/ Non-Fungible Token .
- Regular users can claim up to 5,600 OBT depending on O-Points.
Timeline Claim Airdrop
