tronz-contract

ABI bindings and contract instances for the tronz TRON SDK.

TRON smart contracts are EVM-compatible, so this crate reuses alloy's sol! macro and ABI codec directly rather than hand-rolling an encoder.

Features

Interacting with arbitrary contracts (dynamic ABI)

Load a JSON ABI at runtime and call any function by name:

use tronz_contract::{Interface, instance::ContractExt};
use alloy_json_abi::JsonAbi;

let abi: JsonAbi = serde_json::from_str(ABI_JSON).unwrap();
let contract = provider.contract(address, abi.into());

// read-only call
let values = contract.call("balanceOf", &[account.into()]).await?;

// state-changing call
let pending = contract.send("transfer", &[to.into(), amount.into()]).await?;
let receipt = pending.get_receipt().await?;

Standard token interfaces (static ABI)

Use the typed wrappers for well-known standards:

use tronz_contract::trc20::Trc20Ext;

let token = provider.trc20(usdt_address);
println!("name    : {}", token.name().await?);
println!("balance : {}", token.balance_of(my_address).await?);

let pending = token.transfer(recipient, amount).await?;
let receipt = pending.get_receipt().await?;

Crate layout

• trc20 — static sol! bindings + Trc20Instance high-level wrapper
• Interface wrapping JsonAbi with O(1) selector lookup
• ContractInstance — generic contract handle
• ContractError and Result type alias
