How it stays safe

1:1 backed. After your LBTC deposit has 2 confirmations, the server signs a claim voucher for it. You claim with your own wallet, and each deposit can be claimed only once. The page shows the vault next to the wLBTC supply (plus deposits still waiting to be claimed) at all times.

You pay only for what you do. Claiming and bridging out are sent from your own wallet, so you pay their Arbitrum gas (usually a few cents of ETH). The server never sends transactions for you.

Hard limits. Each claim is capped per transaction and per 24 hours, so even a stolen server key couldn't print unlimited wLBTC. A voucher works only for its own address, on this contract. A guardian can pause instantly, and the server stops signing if the reserves ever look short.

No double payouts. Every LBTC payout is signed once and written to disk before it's sent. It is checked against the chain before anything new is signed.

Nothing is lost. A deposit with a wrong memo is sent back to you automatically.
