🦀 tronic

A modular, type-safe, async-first Rust client for the Tron blockchain — inspired by Alloy and built for real-world smart contract interaction.

Features

Core Infrastructure

• Typed Smart Contract Calls — Powered by alloy-sol-types macros for compile-time safety
• Dual Protocol Support — Both gRPC (via tonic) and JSON-RPC providers (WIP)
• Pluggable Signers — Local, or custom async signing backends
• Async-First — Built on Tokio for high-performance blockchain interaction

Account Management

• Multi-Signature Support — Complete workflow for threshold signatures
• Permission Management — Modify account permissions programmatically
• Resource Delegation — Handle bandwidth/energy freezing/unfreezing (WIP)

Smart Contract Interaction

• TRC-20 — Type-safe token transfers with alloy-style builders
• Contract ABI Codegen — Generate types from Solidity ABIs (need to implement a wrapper by hand currently)
• Event Filtering — Rich event subscription and historical querying
• Transaction Estimation — Precise energy & bandwidth calculation with fallback modes

Advanced Transaction Features

• Transaction Batching — Group multiple operations atomically (WIP)
• Deadline Handling — Automatic/manual transaction expiration management

Quickstart

use tronic::client::Client;
use tronic::client::pending::AutoSigning;
use tronic::domain::address::TronAddress;
use tronic::provider::grpc::GrpcProvider;
use tronic::signer::LocalSigner;
use tronic::trx;

// Construct a client with a signing backend
let client = Client::builder()
    .provider(
        // Build grpc provider
        GrpcProvider::new(
            "https://grpc.trongrid.io:50051".parse()?,
            tronic::client::Auth::None,
        )
        .await?,
    )
    .signer(LocalSigner::rand())
    .build();

// Send transaction
let txid = client
    .send_trx()
    .to(TronAddress::rand())
    .amount(trx!(1.0 TRX))
    .build::<AutoSigning>() // Uses automatic signing strategy
    .await?
    .broadcast(&())
    .await?;
