 * Onchain Bitcoin wallet implementation for traditional Bitcoin transactions.
 *
 * This wallet handles regular Bitcoin transactions on the blockchain without
 * using the Ark protocol. It supports P2TR (Pay-to-Taproot) addresses and
 * provides basic Bitcoin wallet functionality.
 *
 * @example
 * ```typescript
 * const wallet = await OnchainWallet.create(identity, 'mainnet');
 * const balance = await wallet.getBalance();
 * const txid = await wallet.send({
 *   address: 'bc1...',
 *   amount: 50000
 * });
 * ```
