You post the terms, or you take someone else’s. The connected wallet is the record.
Connect a wallet to see its bridges and loans.
Cross one chain. Receive on the other.

Price protection and network details
Filling an offer that is already waiting adds a 0.4% platform fee on top of what you send. An offer that sits until someone else takes it adds no platform fee. Mining fees still apply.

Connect a wallet to see its bridges and loans.
Loans
Borrow against coins you lock, or lend coins to someone who locks theirs. Repay any time before the due day. No account.
Checking two exchanges.
The borrower locks collateral first. The lender sends the borrowed coins only after that lock confirms. Those coins go straight to the borrower.
Repay the full amount any time before the due day. There is no platform fee and no way to add collateral later.
If it is not repaid, the collateral goes to the lender on the due day. A price ending can happen sooner, and only when two exchanges agree and both prices are under a minute old.
If the borrowed coins never arrive, the borrower can take the collateral back after the delivery window. Thirty days after the due day, that way back opens again.
Each closing already names its receiver. Two NexumBit keys choose which signed closing is broadcast. They cannot change who receives it.

NexumBit does not hold the coins. You lock your own collateral, and borrowed coins go straight to the borrower. A closing pays only the person named when the loan was signed.

How it moves
Each step is a transaction your wallet signs, enforced by the chain rather than by us.
Take an offer or post one. Your wallet signs the order; no coins move yet.
Your wallet is the account.
No email, no password, no profile on our side. Connect a wallet to act; disconnect and nothing about you stays behind.
