 * This wallet accepts a mnemonic (aka seed phrase) and is able to directly sign
 * and broadcast transactions to the chain without relying on an external wallet
 * like Keplr or Station. Use this if you want to programmatically broadcast
 * transactions. Unlike the other wallets, there is no Controller class and this
 * object must be instantiated directly.
 *
 * ```ts
 * // Example usage for Osmosis chain
 * const wallet = new MnemonicWallet({
 *   mnemonic: "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about", // Example 12-word mnemonic for testing
 *   bech32Prefix: "osmo",
 *   chainId: "osmosis-1",
 *   rpc: "https://rpc.osmosis.zone",
 *   gasPrice: {
 *     amount: "0.0025",
 *     denom: "uosmo",
 *   },
 *   coinType: 118, // optional (default: 118)
 *   index: 0, // optional (default: 0)
 * });
 * console.log("Address:", wallet.address); // prints the bech32 address
 *
 * // Sign an arbitrary message
 * const { signature } = await wallet.signArbitrary("Hello from @sonr.io/es!");
 * console.log("Signature:", signature);
 *
 * // Sign and broadcast a tx
 * const unsignedTx = { msgs: [...], memo: "Hello Cosmos!", timeoutHeight: 0n };
 * const res = await wallet.broadcastTxSync(unsignedTx, 1.4); // Uses 1.4x fee multiplier
 * console.log("Tx result:", res);
