Rollup aware chains objects extending wagmi

rollup-chains •

A simple drop in replacement for wagmis existing chain object

The source code is very small just 1 file src/rollupChains.ts. But this simple abstraction can really clean up your code significantly if your DAPP is multichain

Installation

npm

1npm i @roninjin10/rollup-chains

pnpm

1pnpm i @roninjin10/rollup-chains

yarn

1yarn add @roninjin10/rollup-chains

Usage

Use just like @wagmi/chains but with some extra rollup properties

1// import {mainnet, optimism} from 'wagmi/chains'
2import { mainnet, optimism } from "@roninjin10/rollup-chains";
3
4// the extend wagmi interface
5mainnet.id
6optimism.rpcUrls
7
8// with added rollup specific properties
9mainnet.l1 // returns mainnet
10mainnet.l2 // returns optimism
11optimism.12 // returns optimism
12optimism.l1 // returns mainnet
13optimism.isL2 // returns true
14optimism.isL2 // returns false

Why

Instead of writing bugprone and unergonomic code like this

1const currentChainId = connectChain.id
2const l1ChainId = connectedChain.id === 1 ? 1 : connectedChain.id === 10 ? 1 : connectedChain.id === 5 ? 5 : connectedChain.id === 420 ? 5 ...

Or needing to add helper functions simply swap these chains in for wagmi chains to get rollup aware chains!

1const currentChainId = connectedChain.id;
2// this will return the l1 chain regardless of if user is connected to testnet, mainnet, l1, or l2
3const l1ChainId = connectedChain.l1.id;
