# Deploy on Celo with thirdweb

> How to point thirdweb's contracts, SDK and dashboard at Celo Mainnet and Celo Sepolia

thirdweb is a third-party platform for deploying contracts and building apps on EVM chains. This page is for app developers who have already chosen thirdweb and need the Celo-specific configuration; thirdweb's own documentation is the source of truth for everything else.

***

## Celo chain configuration

thirdweb v5 exports both Celo networks from `thirdweb/chains`.

```ts theme={null}
// thirdweb v5
import { celo, celoSepoliaTestnet } from "thirdweb/chains";

const mainnet = celo;                // Celo Mainnet, chain ID 42220
const testnet = celoSepoliaTestnet;  // Celo Sepolia testnet, chain ID 11142220
```

Pass the chain to `getContract`, `ConnectButton` and the rest of the SDK as you would for any other network. Chain IDs, RPC URLs and the faucet are on [Network information](/build-on-celo/network-overview).

When deploying from the thirdweb dashboard, select **Celo** or **Celo Sepolia** as the network in the deploy options.

## Fee abstraction

Paying gas in a stablecoin instead of CELO uses Celo's `feeCurrency` transaction field, which not every EVM library sets. [viem](/tooling/libraries-sdks/viem) and [wagmi](https://wagmi.sh) support it natively — see [Fee abstraction](/build-on-celo/fee-abstraction/overview) for what the field expects, including the adapter-address rule for 6-decimal tokens.
