Orbiter Finance Introduction

Orbiter Finance is a decentralized cross-chain bridge designed for fast and low-cost transfers of Ethereum-native assets. As a Layer2 infrastructure, it connects multiple blockchain ecosystems, enabling seamless interoperability between Ethereum, StarkNet, zkSync, Loopring, Arbitrum, Arbitrum Nova, Optimism, Polygon, BNB Chain, ZKSpace, Immutable X, dYdX, Metis, and Boba. Users can experience near-instant transactions with minimal fees.

Innovative Cross-Chain Mechanism

Orbiter Finance employs a unique cross-chain mechanism, introducing two core roles:

• Sender: The user who initiates the cross-chain transfer.

• Maker: A liquidity provider who locks excess collateral in Orbiter’s smart contract and processes cross-chain transactions.

The Sender deposits assets into the Maker on the source chain. The Maker then releases the equivalent assets on the destination chain, ensuring a fast and secure cross-chain transfer process.

Technical Architecture

Orbiter Finance leverages three key smart contracts to ensure secure cross-chain transactions:

• MDC (Maker Deposit Contract) – Stores Maker’s funds, ensuring collateralized cross-chain transfers and serving as an arbitration mechanism.

• EBC (Event Binding Contract) – Maintains cross-chain fee structures and Maker commission rules.

• SPV (Simple Payment Verification) – Creates an independent transaction verification mechanism for each supported blockchain ecosystem, ensuring transaction validity.

These contracts are deployed on Ethereum-compatible networks, ensuring security, transparency, and efficiency in cross-chain asset transfers.

Vision of Orbiter Finance

Orbiter Finance emerged during the rapid expansion of Ethereum’s Layer2 ecosystem, aiming to break cross-chain asset silos and facilitate fluid movement between rollups. Currently, Ethereum mainnet and its L2 networks (e.g., StarkNet, zkSync, Arbitrum, Optimism, and Loopring) operate as independent “blockchain planets”, but asset mobility between them remains limited.

Additionally, sidechains like BSC, Polygon (Matic), and Gnosis (xDai) have gained traction, yet high cross-chain transaction fees deter users from migrating assets. Orbiter Finance seeks to build a “cross-planet transportation system,” akin to the world of Dune, providing a fast, secure, and cost-efficient cross-chain solution for blockchain users.

Ecosystem & Role System

Orbiter Finance introduces a decentralized cross-chain network with a well-defined role system, encouraging user and developer participation:

• Planet – Represents a Layer1 mainnet or Layer2 rollup that supports smart contracts.

• SpacingGuild – A future DAO governing cross-chain interoperability standards.

• Orbiter Project – The open-source cross-chain infrastructure powering different blockchain interactions.

• Wormhole – Custom cross-chain protocols (e.g., token bridging, NFT cross-chain transfers, and multi-asset swaps).

• WormholeCreator – Developers who build custom cross-chain solutions on the Orbiter ecosystem.

• Sender – Regular users performing cross-chain transfers via Orbiter Finance.

• Maker – Liquidity providers who facilitate cross-chain transactions.

• Dock – Integrations such as wallets and exchanges that enable cross-chain functionalities.

• Navigator – Server nodes managing Sender assets and executing transactions on the target network.
