How the Bitcoin web wallet works

The wallet creates or restores a BIP39 recovery phrase and derives standard Bitcoin Mainnet addresses locally in your browser. The default interface combines supported branches into one BTC balance so you do not need to choose a technical address format before sending.

Supported Bitcoin address standards

The wallet discovers BIP44 Legacy addresses beginning with 1, BIP49 Nested SegWit addresses beginning with 3, BIP84 Native SegWit addresses beginning with bc1q, and BIP86 Taproot addresses beginning with bc1p.

Balance discovery

On the first open, address discovery checks receive and change branches using a standard gap limit. Later refreshes reuse the saved discovery state and check known addresses plus a rolling look-ahead window instead of scanning every branch from the beginning.

Sending Bitcoin

When you send BTC, the wallet selects confirmed spendable UTXOs automatically, estimates the network fee and signs the transaction in the browser. Standard Bitcoin Mainnet recipient addresses beginning with 1, 3, bc1q and bc1p are supported.
