Crate nectar_contracts 

Swarm contract bindings and deployment information.

This crate provides type-safe Solidity contract bindings using Alloy’s sol! macro, along with deployment information for mainnet and testnet.

Deployment Information

Each contract has a deployment struct that bundles address and deployment block:

use nectar_contracts::mainnet;

let postage = mainnet::POSTAGE_STAMP;
assert_ne!(postage.address, alloy_primitives::Address::ZERO);
assert!(postage.block > 0);

Contract Bindings

The sol! macro generates call types, return types, and event types that can be used with alloy providers:

use alloy_sol_types::SolCall;
use nectar_contracts::{IPostageStamp, mainnet};

// Encode a call
let call = IPostageStamp::batchOwnerCall { batchId: batch_id };
let encoded = call.abi_encode();
