bcoin Setup

Required Environment:

• BCOIN_WALLET_URL
• BCOIN_PASSWORD
• BCOIN_WALLET_ID: The id of the wallet, that should be created
• EXTENDED_RANDOM_PUBKEY: An public key in extended format. A random key is fine, since we'll import a diffrent address. Can be generated here: https://iancoleman.io/bip39
• BCOIN_WALLET_PASSPHRASE: Passphrase to secure the wallet
• POOL_ADDRESS: Address that should be added. This is the only address we can send from
• BCOIN_RESCAN_HEIGHT: After adding of the pool address, existing transactions are not visible. Use the height of the earliest transaction from/to the pool.

Run yarn bcoin-setup

Use yarn bcoin-info to get info about the wallet with the configured wallet-id.
