Overview

BRC-100 wallet implementation.

All 28 BRC-100 methods are implemented directly — the 9 crypto operations are inlined here, with substrate delegation wired at the top of each method. No inheritance; behaviour is fully self-contained.

Examples:

Create a simple transaction

client = BSV::Wallet::Client.new(private_key)
result = client.create_action({
  description: 'Pay invoice',
  outputs: [{ locking_script: '76a914...88ac', satoshis: 1000,
              output_description: 'Payment' }]
})
