Frequently Asked Questions

Yes, 100%! The vault contract is strictly non-custodial. You retain full sovereignty to click Emergency Refund and receive 100% of your deposited ETH back at any time prior to L2 bridging.

It is an automated anti-spoof protection guard. The relayer and smart contract will only execute bridging once the official GIWA/Dunamu team deposits at least 5.0 ETH collateral into the OptimismPortal, eliminating any risk of fake portals.

A standard 0.5% protocol fee is transparently deducted upon initial deposit. This fee sustains high-availability RPC nodes, WebSocket infrastructure, and 24/7 automated relayer bot execution.
