Send Bitcoin offline via SMS

Text a signed raw transaction to this number. Created for Orum Wallet.

How it works

Bitsms is not a wallet. Instead, it is an SMS to Bitcoin relay where you sign a transaction in your wallet and text it to this number. Most wallets allow you to sign raw transactions offline. Bitsms is open source and available on Github.




Once the transaction is sent successfuly, Bitsms replies with the transaction ID. If the same transaction has already been sent or contains errors, Bitsms will not reply.
