What is Orbiter Finance?
Orbiter Finance is a decentralized cross-rollup bridge specifically designed for fast and low-cost transfers between Ethereum Layer 2 networks. Launched in 2022, Orbiter has become one of the most popular bridges for moving assets between rollups like Arbitrum, Optimism, zkSync, StarkNet, Linea, and Base. The protocol uses a unique "Maker" system where liquidity providers (Makers) stake collateral and process cross-chain transfers on behalf of users. This design enables fast transfers without requiring large liquidity pools on each chain. Orbiter doesn't mint wrapped tokens. Instead, it facilitates the movement of native assets between chains.

How Orbiter Works
User sends tokens to Orbiter contract with destination encoding, Makers monitor for incoming transfers, Maker sends equivalent tokens on destination chain, small identification code added for matching, Maker reclaims funds from source chain contract.
Maker Collateral System
Makers stake collateral (often 10x typical transfer size), collateral slashed for failure to complete, smart contract enforces honest behavior.
Supported Chains
Optimistic Rollups: Arbitrum One, Arbitrum Nova, Optimism, Base, Mantle ZK Rollups: zkSync Era, zkSync Lite, StarkNet, Polygon zkEVM, Linea, Scroll Other EVM: Polygon, BNB Chain, Zora, ModeYield Opportunities
1. Maker Operation (15-40% APY potential)
Operate as an Orbiter Maker, stake collateral across chains, earn fees from bridge volume.
2. OBT Token (Upcoming)
Governance token launching, potential staking rewards, airdrop for early users.
