Orbiter Finance is a decentralized bridge designed to facilitate the transfer of Ethereum-native assets, such as ETH, between various Layer 2 (L2) networks. It supports a wide range of networks, including Optimism, Arbitrum, zkSync, Polygon, and more, enabling users to move assets swiftly and cost-effectively across chains.
Fast and Affordable Transfers: Orbiter Finance offers quick transaction times, often under 10 seconds, with competitive fees, making it an efficient choice for cross-chain asset movement. Medium
Decentralized Architecture: The bridge operates without centralized intermediaries, enhancing security and trustlessness in asset transfers.
Broad Network Support: Beyond Optimism and Arbitrum, Orbiter supports multiple L2 networks, providing users with flexibility in their DeFi activities.
Orbiter Finance employs a unique mechanism involving "Makers" and "Senders":
Sender: Initiates the transfer by sending assets to a Maker's address on the source chain.
Maker: Receives the assets and, upon confirmation, releases equivalent assets to the Sender on the target chain.
This system ensures that assets are securely and efficiently bridged between networks without the need for smart contracts on the source chain.
Orbiter Finance incorporates several security protocols:
Maker Deposit Contracts (MDC): Require Makers to deposit collateral, ensuring they have a stake in the system's integrity.
Event Binding Contracts (EBC): Monitor and validate cross-chain transactions, linking source and target chain activities.
Simple Payment Verification (SPV): Provides proof of transaction existence on the source chain, enhancing trust in the bridging process.
