You will have up to 60 days after signup to deposit Bitcoin. After that time, you will need to submit your ID for verification in order to continue depositing Bitcoin.
There are currently two methods you can use to receive Bitcoin on River: on-chain and Lightning. This guide will walk you through transferring Bitcoin in both ways.
Don't worry if you don't see your Bitcoin right away! It may take some time before your Bitcoin is received by River. If you are transacting via the onchain network, River applies confirmation logic to give you an expectation of when your transaction will reflect in your account:
Any transaction less than 0.1 BTC requires 2 confirmations
Any transaction less than 0.5 BTC requires 3 confirmations
Any transaction greater than or equal to 0.5 BTC requires 6 confirmations
