# Alloy Multicall


Easily send multicall transactions using [Alloy].

[Alloy]: https://github.com/alloy-rs/alloy

## Installation


Add `alloy-multicall` to your `Cargo.toml`.

```toml
alloy-multicall = "0.9.2"
```

## Example


```rust
use alloy::{
    dyn_abi::DynSolValue,
    primitives::{address, U256},
    sol,
    sol_types::JsonAbiExt as _,
};
use alloy_multicall::Multicall;

sol! {
    #[derive(Debug)]
    #[sol(abi)]
    function getAmountsOut(uint amountIn, address[] memory path)
        public
        view
        virtual
        override
        returns (uint[] memory amounts);
}

#[tokio::main]

async fn main() {
    tracing_subscriber::fmt::init();

    let rpc_url = "https://rpc.ankr.com/eth".parse().unwrap();
    let provider = alloy::providers::ProviderBuilder::new().on_http(rpc_url);
    let uniswap_v2 = address!("7a250d5630b4cf539739df2c5dacb4c659f2488d");

    let mut multicall = Multicall::with_provider_chain_id(&provider).await.unwrap();

    let amounts_out = getAmountsOutCall::abi();

    multicall.add_call(
        uniswap_v2,
        &amounts_out,
        &[
            DynSolValue::from(U256::from(1000000000000000000_u128)),
            DynSolValue::Array(vec![
                address!("C02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2").into(),
                address!("6982508145454Ce325dDbE47a25d4ec3d2311933").into(),
            ]),
        ],
        false,
    );

    let results = multicall.call().await.unwrap();
    println!("{:?}", results);
}
```
