deriveAddress method
Derive an address @param {String} seed TransactionChain seed @param {int} index Number of transaction in the chain @param {String} curve Elliptic curve to use ("ed25519", "P256", "secp256k1") @param {String} hashAlgo Hash algorithm ("sha256", "sha512", "sha3-256", "sha3-512", "blake2b")
Implementation
String deriveAddress(String seed, int index,
{String curve = 'P256', String hashAlgo = 'sha256'}) {
final KeyPair keypair = crypto.deriveKeyPair(seed, index, curve: curve);
return uint8ListToHex(crypto.hash(keypair.publicKey, algo: hashAlgo));
}
