Key derivation and wallet recovery
There is no key derivation or recovery tool on this site, on purpose. SwapChan never asks for, receives, holds or derives private keys, seed phrases or wallet passwords, and never signs anything.
Deriving keys from a seed phrase, decrypting an old wallet file (wallet.dat, keystore JSON, Electrum, MultiBit, Armory) or repairing a seed phrase with typos all touch secrets. That work belongs offline, on your own machine, in blocktools, never in a web page or an AI chat.
What you can do here with public data only: list the addresses of an extended public key with the xpub address tool, check an address with the address validator, and see what an address holds with Find money.
Never paste a private key, seed phrase or wallet password into any website, including this one. Anyone offering to recover your wallet online is a scam risk.
