Following on the [releases of Rainbowkit 1.0](https://twitter.com/rainbowdotme/status/1656312056738349057) and [wagmi 1.0](https://next.wagmi.sh/react/migration-guide#1xx-breaking-changes) the clabs App Tooling team has updated its [celo config for rainbowkit to 1.0](https://github.com/celo-org/rainbowkit-celo/releases/tag/v1.0.0) as well.

This is a big but not difficult move as rainbowkit / wagmi 1.0 replaces `ethers` for `viem`, which is [about a 3rd](https://bundlephobia.com/package/viem@0.3.31) of [the size of ethers](https://bundlephobia.com/package/ethers@5.7.2). This is especially impactful for those accessing dapps from bandwidth constrained connections.

Combined with the [freshly released @celo/abis package](https://forum.celo.org/t/release-new-celo-abis-library-to-conveniently-import-core-contract-abis/5816) we have found using viem + wagmi + rainbowkit to be a productive and enjoyable way to build dapps on celo.
