Antd.Ffi 0.0.9

Antd.Ffi — direct-network .NET client for Autonomi

.NET 8 bindings over the ant-ffi Rust crate, generated with uniffi-bindgen-cs. The client joins the Autonomi network directly: no daemon, no HTTP hop. The native library is bundled in the package for win-x64, win-arm64, linux-x64, linux-arm64, osx-x64 and osx-arm64 and selected automatically at restore time.

For the daemon-backed client (the recommended path for most apps: the daemon holds the wallet and does the networking) see Antd.Sdk.

Installation

dotnet add package Antd.Ffi

Quick start

using AntFfi;

Console.WriteLine(AntFfiMethods.AntFfiVersion());

// Offline: derive the EVM address for a wallet key (no RPC contacted).
var wallet = Wallet.FromPrivateKey(
    "ac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80",
    "http://localhost:8545",
    "0x5FbDB2315678afecb367f032d93F642f64180aa3",
    "0x5FbDB2315678afecb367f032d93F642f64180aa3");
Console.WriteLine(wallet.Address());

// Online: connect to a local devnet from its manifest and round-trip data.
var client = await Client.ConnectFromDevnetManifest("/path/to/devnet-manifest.json");
var put = await client.DataPutPublic(System.Text.Encoding.UTF8.GetBytes("hello"), PaymentMode.Auto);
var got = await client.DataGetPublic(put.address);

The surface mirrors the Python (ant-sdk) and Node (@withautonomi/ant-sdk) bindings: Client (connect variants, data/file/chunk put and get, cost estimates, external-signer prepare/finalize, progress listeners), Wallet, and typed records/enums. All Client methods are async (Task<T>), bridged onto the crate's tokio runtime.

Compatibility

Targets .NET 8. Package version tracks the ant-ffi crate version (AntFfiMethods.AntFfiVersion() returns it). Linux builds are made against glibc 2.28 (manylinux_2_28), so any distribution from roughly 2019 on works. Not for browsers or Blazor WebAssembly: direct networking needs a native process.

Building from source

See ffi/README.md: ffi/scripts/build.sh builds the crate, generates AntFfi/Generated/, and builds this solution. dotnet test runs offline smoke tests (version + wallet derivation); the devnet round-trip is exercised by the publish workflow's smoke consumer.
