Create a Fungible Token

Fungible tokens on Hedera behave like ERC-20 tokens — every unit is identical and divisible. You configure the token's properties in a CreateTokenParams object, then call CreateTokenAsync on a ConsensusClient.

Code

class Program
{
    static async Task Main(string[] args)
    {
        // Usage: dotnet run -- https://2.testnet.hedera.com:50211 0.0.5 0.0.1001 302e...
        var endpointUrl = args[0];
        EntityId.TryParseShardRealmNum(args[1], out var nodeAccount);
        EntityId.TryParseShardRealmNum(args[2], out var payerAccount);
        var payerKey = Hex.ToBytes(args[3]);          // DER-encoded Ed25519 private key hex

        await using var client = new ConsensusClient(ctx =>
        {
            ctx.Endpoint = new ConsensusNodeEndpoint(nodeAccount!, new Uri(endpointUrl));
            ctx.Payer = payerAccount;
            ctx.Signatory = new Signatory(payerKey);
        });

        var treasury = payerAccount!;
        var adminEndorsement = new Signatory(payerKey).GetEndorsements().First();

        var receipt = await client.CreateTokenAsync(new CreateTokenParams
        {
            Name = "My Token",
            Symbol = "MTK",
            Circulation = 1_000_000,
            Decimals = 2,
            Ceiling = 10_000_000,
            Treasury = treasury,
            Administrator = adminEndorsement,
            SupplyEndorsement = adminEndorsement,
            Memo = "Created via Hiero SDK"
        });

        Console.WriteLine($"Token ID: {receipt.Token}");
    }
}

What each parameter does

Parameter Description
Name Human-readable token name displayed in wallets and explorers.
Symbol Ticker symbol (like a currency code), up to 100 characters.
Circulation Initial supply in the smallest unit. With Decimals = 2, a circulation of 1,000,000 represents 10,000.00 tokens.
Decimals Number of decimal places. Determines how the smallest unit maps to the display value.
Ceiling Maximum supply the token can ever reach. Set to 0 for unlimited.
Treasury The account that initially holds all the supply and receives minted tokens.
Administrator Public key authorized to update or delete the token. Omit to make the token immutable.
SupplyEndorsement Public key authorized to mint and burn. Separate from Administrator in production.
Memo Optional short description (max 100 bytes).
