Following on the releases of Rainbowkit 1.0 and wagmi 1.0 the clabs App Tooling team has updated its celo config for rainbowkit to 1.0 as well.
This is a big but not difficult move as rainbowkit / wagmi 1.0 replaces ethers for viem, which is about a 3rd of the size of ethers. This is especially impactful for those accessing dapps from bandwidth constrained connections.
Combined with the freshly released @celo/abis package we have found using viem + wagmi + rainbowkit to be a productive and enjoyable way to build dapps on celo.
