MyFactomWallet is a client-side interface Factom wallet which can be used online without having to synchronize the Factom blockchain. It provides the user with access to the Factom blockchain, but does NOT store, control or have access to ANY user wallet or blockchain information including private key / seed pairs or transaction data. The user is responisble for storing their own keys. Myfactomwallet is the only wallet currently offering support for the Ledger Nano S hardware wallet.
