Ethereum

Balance Of

string network = "mainnet"; // mainnet ropsten kovan rinkeby goerli
string account = "0x99C85bb64564D9eF9A99621301f22C9993Cb89E3";

BigInteger wei = await Ethereum.BalanceOf(network, account);
print("wei: " + wei);

Create Transaction

Create an unsigned transaction. User can sign offline.

string network = "rinkeby"; // mainnet ropsten kovan rinkeby goerli
string from = "0x35706484aB20Cbf22F5c7a375D5764DA8166aE1c";
string to = "0x7E3bE66431ba73956213C40C0828355D1A7894D3";
string eth = "0.00111";

Transaction transaction = await Ethereum.CreateTransaction(network, from, to, eth);

print("network: " + transaction.network);
print("to: " + transaction.to);
print("wei: " + transaction.wei);
print("nonce: " + transaction.nonce);
print("gasLimit: " + transaction.gasLimit);
print("gasPrice: " + transaction.gasPrice);
print("hex: " + transaction.hex);

Broadcast Transaction

Broadcast a signed transaction.

string network = "rinkeby"; // mainnet ropsten kovan rinkeby goerli
string signedTransaction = "0xf86b04843b9aca0083989680947e3be66431ba73956213c40c0828355d1a7894d38703f18a03b36000802ca0043ab6289f2a44dd911bfb3658cfac12710354a3e0cef35544c9348b15f9f6f7a018d36b8d5b61dc00a54293528d0edd8a4a7c9f064817825c7e8cb8167b240860";

string transactionHash = await Ethereum.Broadcast(network, signedTransaction);
print (transactionHash);

Verify

Verify a signed message.

string network = "mainnet"; // mainnet ropsten kovan rinkeby goerli
string message = "YOUR_MESSAGE";
string signature = "0x94bdbebbd0180195b89721a55c3a436a194358c9b3c4eafd22484085563ff55e49a4552904266a5b56662b280757f6aad3b2ab91509daceef4e5b3016afd34781b";

string account = await Ethereum.Verify(network, message, signature);
print (account); // 0xC52C1FB0B9681e1c80e5AdA8eEeD992C0C2706eE

ERC1155

ERC-1155 contracts have two additonal fields.

  • Contract address: The address that stores the balances of the token.

  • Token Id: The specific token inside of the contract address.

For example. The contract address 0x5e30b1d6f920364c847512e2528efdadf72a97a9 can store all digital chess pieces. A pawn can be token id 17.

Balance Of

string network = "rinkeby"; // mainnet ropsten kovan rinkeby goerli
string contract = "0x2ebecabbbe8a8c629b99ab23ed154d74cd5d4342";
string account = "0xaca9b6d9b1636d99156bb12825c75de1e5a58870";
string tokenId = "22";

BigInteger balance = await ERC1155.BalanceOf(network, contract, account, tokenId);

print (balance)

Balance Of Batch

Balance of batch will get the balance of a list of accounts and token ids. For example:

Get the balance of account 0xaCA9B6D9B1636D99156bB12825c75De1E5a58870 with token id 17 and

balance of account 0xaCA9B6D9B1636D99156bB12825c75De1E5a58870 with token id 22

string network = "rinkeby"; // mainnet ropsten kovan rinkeby goerli
string contract = "0x2ebecabbbe8a8c629b99ab23ed154d74cd5d4342";
string[] accounts ={ "0xaCA9B6D9B1636D99156bB12825c75De1E5a58870", "0xaCA9B6D9B1636D99156bB12825c75De1E5a58870" };
string[] tokenIds = { "17", "22" };

List<BigInteger> batchBalances = await ERC1155.BalanceOfBatch(network, contract, accounts, tokenIds);

foreach (var balance in batchBalances)
{
  print ("batchBalance:" + balance);
}

URI

Returns meta data about the token.

string network = "rinkeby"; // mainnet ropsten kovan rinkeby goerli
string contract = "0x2ebecabbbe8a8c629b99ab23ed154d74cd5d4342";
string tokenId = "17";

string uri = await ERC1155.URI(network, contract, tokenId);

print (uri);
