Descriptor Address Derivation

Browser-only derivation: descriptor validation and every receiving/change address derivation happen locally in this browser. Your descriptor and keys never leave the browser. Only resulting addresses—up to 200 pairs per scan—are sent to Blockstream Esplora to check balance and usage.

Public Multipath Descriptor

Enter a watch-only ranged descriptor containing /<0;1>/*. Branch 0 is receiving and branch 1 is change. Private keys are rejected.

Start Index

Address Count

The scan keeps funded addresses and finds this many never-used addresses for both receiving and change, checking at most 200 pairs.
