Deposit addresses · BTC

Bitcoin deposit addresses for your users.

Give every one of your users a permanent Bitcoin address they can deposit to any time. It has no private key, and we pay the network fee to collect what lands on it. The asset customers ask for by name. Its own chain, its own address formats, no tokens.

Start building How deposit addresses works

BTC on 1 chain.

Enable the ones your users need. Each gives that user their own address, and enabling a new one later gives it to the users you already have.

BTC on Bitcoin: Bitcoin has no token layer, so BTC is the only thing that can arrive. We offer four address formats so a sender whose wallet cannot pay a bech32 address is not stuck.

Issuing a Bitcoin address.

Create the customer
One POST with your own user id as the reference. This is the record everything else hangs off.
Ask for an address per chain
One per (customer, chain), and it does not change. The same customer has the same address on every EVM chain, and you can show it again tomorrow without calling us.
