cd lbcwallet
go build .

lbcd & lbcwallet

lbcwallet is not an SPV client and requires connecting to a lbcd node for asynchronous blockchain queries and notifications over websockets.

lbcwallet can serve wallet related RPCs and proxy lbcd RPCs to the assocated lbcd. It's sufficient for a user to connect just the lbcwallet instead of both.

Getting Started

Create a new wallet with a randomly generated seed or an existing one.

lbcwallet --create

Do you have an existing wallet seed you want to use? (n/no/y/yes) [no]: no
Your wallet generation seed is: 3d005498ad5e9b7439b857249e328ec34e21845b7d1a7d2a5641d4050c02d0da

The created wallet protects the seed with a default passphrase ("passphrase"), which can be override with -p option:

lbcwallet --create -p my-passphrase

Start wallet server, and connect it to a lbcd instance.

lbcwallet --rpcuser=rpcuser --rpcpass=rpcpass # --rpcconnect=localhost:9245

At startup, the wallet will try to unlock itself with the default passphrase (passphrase) or an user provided one (using -p option).

If the passphrase does not match, the wallet remains locked. User can lock/unlock the wallet using walletlock and walletpassphrase RPCs.

lbcwallet --rpcuser=rpcuser --rpcpass=rpcpass -p my_passphrase
