A redeposit is a transaction that moves your wallet’s bitcoin to a new address within your wallet.
If you are using a Bitcoin 2-of-2 or Liquid standard wallet, you will be prompted to redeposit any funds in your wallet that have not moved for 12 months (or a custom timelock period). The redeposit is required to refresh the timelock used in the Blockstream app's special multisig security model.
If you have funds in your wallet that use legacy nLockTime timelocks, you will receive the notification prompting you to complete a redeposit via email (you need to set up an email address to receive nLockTime notifications).
Warning: If the timelock expires, you can spend the funds in your wallet without two-factor authenticator (2FA) confirmation until you complete a redeposit.
Perform a redeposit
1.
Navigate to the Transact tab, then tap Receive and copy a new address from your wallet.
2.
Next, tap Send and past the address to send funds back to yourself. Make sure to select Send all to ensure that all expired coins are redeposited and the timelock is reset.
