Netezos

The first version of the library has been moved to the v1 branch for historical purposes.

Netezos is a cross-platform Tezos SDK for .NET developers, simplifying the access and interaction with the Tezos blockchain.

The following features have been implemented so far:

Namespace	Description	Status
Netezos.Contracts	Interaction with Tezos smart contracts	Ready to use. Dynamic wrapper: in progress...
Netezos.Forge	Forging (encoding) operation bytes	Ready to use
Netezos.Keys	Working with keys, HD keys, signing, verifying signature, etc.	Ready to use
Netezos.Ledger	Interaction with Tezos Ledger App	Ready to use (separate package)
Netezos.Rpc	Tezos RPC wrapper	Ready to use

For full documentation and API Reference, please refer to the Netezos website

Contribution

Netezos is an open development project so any contribution is highly appreciated, starting from documentation improvements, writing examples of usage, etc. and ending with adding new features (as long as these features do not break existing API or are only intended for one person and for very specific use case).

Do not hesitate to use GitHub issue tracker to report bugs or request features.

Support

Feel free to join our Discord server, Telegram chat, or find us in Tezos Dev Slack. We will be glad to hear any feedback and feature requests and will try to help you with general use cases of the Netezos library.

Getting 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.
