    Get started

    Let's consider the most common use case - sending a transaction.

    Installation

    PM> Install-Package Netezos

    Create private key

    // generate new key
    var key = new Key();
    
    // or use existing one
    var key = Key.FromBase58("edsk4ZkGeBwDyFVjZLL2neV5FUeWNN4NJntFNWmWyEBNbRwa2u3jh1");
    
    // use this address to receive some tez
    var address = key.PubKey.Address; // tz1SauKgPRsTSuQRWzJA262QR8cKdw1d9pyK
    

    Get some data from RPC

    using var rpc = new TezosRpc("https://mainnet-tezos.giganode.io/");
    
    // get a head block
    var head = await rpc.Blocks.Head.Hash.GetAsync<string>();
    
    // get account's counter
    var counter = await rpc.Blocks.Head.Context.Contracts[address].Counter.GetAsync<int>();
    

    Forge an operation

    Since our address has just been created, we need to reveal its public key before sending any operation, so that everyone can validate our signatures. Therefore, we need to send actually two operations: a reveal and then a transaction.

    Netezos allows you to pack multiple operations into a group and forge/send it as a single batch.

    var content = new ManagerOperationContent[]
    {
        new RevealContent
        {
            Source = address,
            Counter = ++counter,
            PublicKey = key.PubKey.GetBase58(),
            GasLimit = 1500,
            Fee = 1000 // 0.001 tez
        },
        new TransactionContent
        {
            Source = address,
            Counter = ++counter,
            Amount = 1000000, // 1 tez
            Destination = "tz1KhnTgwoRRALBX6vRHRnydDGSBFsWtcJxc",
            GasLimit = 1500,
            Fee = 1000 // 0.001 tez
        }
    };
    
    var bytes = await new LocalForge().ForgeOperationGroupAsync(head, content);
    

    Sign and send

    // sign the operation bytes
    byte[] signature = key.SignOperation(bytes);
    
    // inject the operation and get its id (operation hash)
    var result = await rpc.Inject.Operation.PostAsync(bytes.Concat(signature));
    

    That is it. We have successfully injected our first operation into the Tezos blockchain.
