The default BTC API used in Xverse is https://mempool.space/api/, which sets a limit of 500 UTXOs per address. If your address has reached the UTXO limit set by mempool.space, you may receive an Axios 400 error message when trying to send Bitcoin.
Users can fix this issue by going to:
- Change network
- Edit the BTC API URL to be https://btc-1.xverse.app
You should now be able to consolidate your UTXOs and transact normally.
