Resyncing the SPV file can solve wallet issues such as incorrect balance showing, missing transactions, etc.

How to Resync the SPV File

It is best to initiate an SPV resync from within Bisq. Sometimes this isn't possible, so we include directions on how to initiative an SPV resync from your file system too.

From the Bisq interface

Go to Settings > Network Info and click Delete SPV File and Resync. Bisq will prompt you to restart twice, and depending on the age of your wallet and how many transactions it has, it may take a while to finish syncing. It is normal for your machine to reach high CPU usage levels, and Bisq may not be responsive until syncing has finished.

Where to initiate an SPV resync from within the Bisq interface.

From the file system

Close Bisq, delete the btc_mainnet/wallet/bisq.spvchain from your data directory, start Bisq, wait for it to load, and then restart Bisq again.

Bisq will not prompt you to restart it again—so don't forget to actually do it!

Depending on the age of your wallet and how many transactions it has, it may take a while to finish syncing. During syncing, it's normal for your machine to reach high CPU usage levels, and Bisq may not be responsive until syncing has finished.

Fix an incomplete SPV resync

If the SPV resync hangs, and you have no choice other than restarting Bisq, only to find out the resync starts again from scratch, then, while Bisq is closed, delete the .spvresync file in the wallet folder and try again, Bisq should pick up from where it left off at the previous attempt.

Video Guide

A video guide of this process can be found on the Bisq Youtube channel.
