 * character, which misreads legacy testnet (m/n/2...) and regtest (bcrt1...)
 * addresses as mainnet. Base58 can't distinguish testnet from regtest (they
 * share version bytes), so a base58 testnet-versioned address resolves to
 * networks.testnet. Anything undecodable defaults to mainnet.
 * @param accountAddress - The Bitcoin address
