Recover a Electrum 2.x wallet.
Electrum 2.x is the current line of the widely used lightweight Bitcoin wallet, with a password-encrypted wallet file.
For a forgotten Electrum password when you still have the wallet file.
Yes. Electrum 2.x is one of the formats that reduces to a check-only extract, so the fleet can test passwords against it safely — finding the password never exposes a key that holds funds. GPU-friendly. You pay 15% only if we recover it, and nothing if we don't.
The Electrum 2.x extract, in detail.
Exactly what the fleet receives for this format — and why finding the password still can't move the funds.
What leaves your machine — and what never does
For a Electrum 2.x wallet, this is the entire check-only extract the fleet receives. It can test a password, but it can never be turned back into a key that spends.
electrum2: - the IV for an encrypted master private key (xprv/zprv), or the IV for an imported loose key
- one 16-byte encrypted block from that xprv or key record
- the rest of the encrypted xprv, seed, or private-key material — never sent
- your addresses and balances
The right password decrypts the xprv block to a Base58 extended-private-key prefix such as xprv or zprv, or decrypts a loose-key tail to valid Base58 plus padding.
xprv/zprv or valid Base58 key text electrum2:<iv-hex>:<encrypted-xprv-or-key-block-hex> Illustrative and synthetic — placeholder bytes.
Around 32 bytes for the legacy 2.x xprv or key extract — an IV plus one encrypted key block.
Extractable Electrum 2.x JSON wallets hash the password twice with SHA-256 to form the AES key for encrypted xprv or loose-key material. Fully encrypted Electrum 2.8+ files use a separate PBKDF2-SHA512 plus ECIES/MAC path.
The right password decrypts the xprv block to a Base58 extended-private-key prefix such as xprv or zprv, or decrypts a loose-key tail to valid Base58 plus padding.
electrum2: An open, published format. The agent checks every job matches it before running — so a real wallet can't be disguised as an extract.
