## Deployment of a new Verax instance

When a new instance of Verax is deployed onchain, the SDK needs to be updated with the new addresses.

1. Add a new backend `Conf` object in [src/VeraxSdk.ts](src/VeraxSdk.ts):

   ```typescript
   static DEFAULT_XXX_MAINNET: Conf = {
     chain: xxx,
     mode: SDKMode.BACKEND,
     subgraphUrl: "<SUBGRAPH_URL>",
     portalRegistryAddress: "0x...",
     moduleRegistryAddress: "0x...",
     schemaRegistryAddress: "0x...",
     attestationRegistryAddress: "0x...",
   };
   ```

2. Add a new frontend `Conf` object in [src/VeraxSdk.ts](src/VeraxSdk.ts):

   ```typescript
   static DEFAULT_XXX_MAINNET_FRONTEND: Conf = {
       ...VeraxSdk.DEFAULT_XXX_MAINNET,
       mode: SDKMode.FRONTEND,
   };
   ```

3. Increment the version of the package in [package.json](package.json)
4. Publish the package to [npm](https://www.npmjs.com/package/@verax-attestation-registry/verax-sdk)

   ```bash
   pnpm run publish:public
   ```
