Security First Architecture
At Orbiter Finance, security is our top priority. We've implemented multiple layers of protection:
Smart Contract Audits
Our bridge contracts have undergone rigorous audits by leading blockchain security firms, with all reports publicly available.
Decentralized Validation
Unlike centralized bridges vulnerable to single points of failure, Orbiter uses a decentralized network for transaction verification.
Non-Custodial Design
Users always maintain control of their assets. Funds are only locked temporarily during the transfer process.
Monitoring Systems
24/7 monitoring and alert systems ensure rapid response to any potential issues.
Bug Bounty Program
We maintain an active bug bounty program to encourage security researchers to help identify vulnerabilities.

Start Bridging NowFrequently Asked Questions
How is Orbiter Finance different from native rollup bridges?
Orbiter Finance specializes in direct rollup-to-rollup transfers, avoiding the need to route through Ethereum mainnet. This makes transfers faster and much cheaper than using native bridges which typically require mainnet transactions.
What assets can I transfer with Orbiter Finance?
We currently support ETH and major ERC-20 tokens across our connected networks. The available assets vary by rollup pair. Check our interface for the most current list.
How long do transfers take?
Most transfers complete within minutes, though times can vary slightly depending on network congestion. This is significantly faster than native bridges which often take hours or days.
Is there a minimum transfer amount?
Minimum amounts vary by asset and network pair. The interface will show you any minimum requirements before you initiate a transfer.
Can I cancel a transfer after initiating it?
Once a transfer is initiated, it cannot be canceled as the process is automated by smart contracts. However, transfers typically complete quickly so this is rarely needed.
What happens if a transfer fails?
In the rare event of a failed transfer, our system includes mechanisms to automatically return assets to the sender. You can contact support if you need assistance with a failed transaction.
