This error typically occurs due to a bad request, which can be triggered by several factors including:

  • Unstable network or use of a VPN.
  • User wallet exceeding the UTXO limitation in mempool’s API.

Troubleshooting Steps

Check Network Status: Disable any active VPN and ensure your network connection is stable.

Check UTXO Limitation on Mempool API:

  • Copy this URL:
https://mempool.space/api/address/.../utxo
  • Replace ... with your wallet address, then Enter.
  • Review the number of UTXOs you’re holding or if you’ve reached Mempool’s UTXO limitation of 500.

  • Go to Settings (⚙️) > Select Network.

  • Edit the BTC URL to https://btc-1.xverse.app. You can copy this from the fallback URL if needed.

  • Save your changes.
