Orbiter Finance FAQ
Orbiter Finance FAQ >>>
1. What is Orbiter Finance?
Orbiter Finance is a decentralized cross-rollup bridge with smart contracts only on the destination side and is Ethereum’s future multi-rollup infrastructure.
2. How does Orbiter Finance work in a decentralized way?
Orbiter’s security model has three parts: MDC, EBC, and SPV.
Maker starts the service and earns fees by depositing excess margin in the Orbiter MDC contract.
SPV calculates the Target Tx that meets the requirements after Sender transfers to Maker in the initiating network, and then Maker sends the Target Tx to the Target network.
When there is a dispute, Sender can get back their assets and receive compensation through Orbiter’s MDC contract.
3. Why is optimistic a long-term scheme?
Orbiter uses an optimistic mechanism based on the SPV scheme during high-frequency transfer without a smart contract. It makes cross-environment transfers quick and cheap, which is the basis for a long-term cross-rollup solution.
On the other hand, Orbiter offers sufficient security to solve the contract system for low-frequency disputes without compromising rollups’ safety assumptions.
4. Will Orbiter supports more networks and tokens?
Of course! Not only will Orbiter support more networks and tokens, but it will also enable developers to develop cross-environment transfer protocols based on Orbiter’s contract system. Developers can customize the environment, token type, and amount. Any network with open transfer data could use Orbiter’s mechanism to implement cross-chain designs. At the same time, Maker can also offer services in more tokens.
Sender FAQ >>>
1. Why is it cheap to use Orbiter? How much does it cost?
Orbiter uses an optimistic mechanism based on the SPV scheme during high-frequency transfer without a smart contract, keeping the gas fee low enough.
Sender starts cross-rollup transfer through Orbiter, resulting in a total of 3 costs:
The gas fee is generated on the initiating environment transfer. And Metamask and other wallets collect them.
Withholding fee for transfer in the target environment paid to Maker through Orbiter. The withholding fee is a gas fee prepaid to Maker for returning assets in the target network.
The transaction fee is paid to Maker through Orbiter. Maker can customize the transaction fee, and Orbiter sets the initial value to 0.3% of the transfer amount.
2. Why is it safe with EOA address?
The Sender must first transfer the token to the Maker’s EOA address (not the contract address) in the initiating environment in the transfer process. Maker who provides the transfer for the Sender should deposit a sufficient margin to the Orbiter’s MDC contract, which is like a promise to return assets and compensation to the Sender when a transfer error occurs.
3. Why is there a transfer amount limit?
Temporarily, Orbiter finance is in the Alpha phase. It is necessary to verify the transfer in a real environment more times before canceling the transfer limit to ensure the security of Sender’s assets.
4. Once an incorrect transfer occurs, how do you get back the tokens?
When low-frequency errors occur, the Sender can visit the appeal link and send an arbitration request to MDC in Orbiter. When the arbitration wait time passes, the Sender can get back the asset and receive compensation. Since Orbiter needs to read the Hash value stored by the network in Ethereum Mainnet for arbitration,
And arbitration wait time is the larger value of Source Network withdrawal time and Target Network withdrawal time.
