# getMainContractAddress Returns the address of a main ZKsync Chain Contract. :::warning **This Action is being deprecated.** This method calls an RPC method that [will be removed in a future release](https://github.com/zkSync-Community-Hub/zksync-developers/discussions/1066). Please use the alternatives mentioned below. **Alternatives / Workaround** This method returned the address of the chain contract in L1. This can be retrieved from a call to the BridgeHub contract. 1. Retrieve the BridgeHub contract address using the [`getBridgeHubContractAddress`](/zksync/actions/getBridgehubContractAddress) action. 2. Call the `getZKChain(chainId)` method on the BridgeHub contract. ::: ## Usage :::code-group ```ts [example.ts] import { client } from './config' const address = await client.getMainContractAddress(); ``` ```ts [config.ts] import { createPublicClient, http } from 'viem' import { zksync } from 'viem/chains' import { publicActionsL2 } from 'viem/zksync' export const client = createPublicClient({ chain: zksync, transport: http(), }).extend(publicActionsL2()) ``` ::: ## Returns `Address` Main ZKsync Era smart contract address.
