-Do you want to verify contracts on an EVM chain (or chains)? Great! We don't want to be the single source of truth and encourage you to [run your own Sourcify server instance](/docs/running-server).

+To request an EVM chain(s) to be supported by Sourcify, please open a pull request with the instructions below for a speedy process:
 
 1.  Make sure the new chains are listed in [chains.json](https://github.com/argotorg/sourcify/blob/staging/services/server/src/chains.json) but **this file should not be edited**. It is kept in sync with [chainid.network](https://chainid.network/chains.json) (github: [ethereum-lists/chains](https://github.com/ethereum-lists/chains)) periodically. If your chains are not included, please first add your chains to the [ethereum-lists/chains](https://github.com/ethereum-lists/chains) repository first.

 1.  Provide test contracts:
-    1. Deploy test contracts:
+    1. If your chain has an instance of CreateX ([deployments](https://createx.rocks/deployments)) or Multicall ([deployments](https://www.multicall3.com/deployments)), you can skip this step.
+    1. If not, deploy a Storage.sol contract:
        1. Using the provided script: You can easily deploy both contracts with an account private key using the provided [`script`](https://github.com/argotorg/sourcify/blob/staging/services/server/test/chains/deployContracts.ts), that can be run with `ts-node`. Inside `services/server`, run `npx ts-node test/chains/deployContracts.ts --help` for more information.
        1. If you can't or don't want to paste your private key, deploy [this contract in the Thirdweb dashboard](https://thirdweb.com/0xAA6042aa65eb93C6439cDaeBC27B3bd09c5DFe94/Storage) through the wallet of your choice.
-    2. If you are not able to deploy new test contracts above (e.g. because it costs on a mainnet) you can provide existing contracts. Create a folder `services/server/test/chains/sources/{chainId}` and store the contract source files and metadata of already deployed contracts there.
-
-1.  Add the test for the new chains in `services/server/test/chains/chain-tests.spec.ts` similar to other chains. If you deployed a test contract as described above, the contract and the metadata are the following:
-    - Storage.sol: `shared/1_Storage.sol` and `shared/1_Storage.metadata.json`
+       1. Add the contract address on your chain to [storage-contract-chain-addresses.json](https://github.com/argotorg/sourcify/blob/staging/services/server/test/chains/sources/storage-contract-chain-addresses.json)
 
 1.  To test locally run `export NEW_CHAIN_ID=1,11155111 && npm run test-local:chains` inside `services/server`. Note that this requires `docker-compose`.
