About Primus Network-Core-SDK

When integrating data verification solutions into your backend server, you can utilize the Primus Network Core SDK. For integrating Primus network capabilities with DApps for end users, please refer to the DApp Integration guide.

The Network-Core-SDK allows you to verify data through API endpoint responses. An authorized token or other credential is required to request private data if the data source server requires permissioned access. Note that in the backend integration situation, the developer usually proves their off-chain data in their built application, and the Primus extension is not required. Typical scenarios include proof of reserves, in which a configured web page periodically proves that the stablecoin issuer holds sufficient collateral across off-chain platforms.

Install

npm install

Configure

Create a .env file in the project root:

PRIVATE_KEY=0xYOUR_PRIVATE_KEY

Optional: if you want to enable mTLS, uncomment the mTLS block in index.js and provide your client cert/key strings:

const mTLS = {
  clientCrt: "YourClientCrtString",
  clientKey: "YourClientKeyString",
};

Run

node index.js

You should see logs for:

• submit task result
• attest result
• task result

Customize

Edit these sections in index.js:

• address: your wallet address
• chainId and baseSepoliaRpcUrl: switch to Base mainnet if needed
• requests: request params for your mTLS endpoint
• responseResolves: JSON parse paths for the response fields you want to attest

Notes

• Keep your .env out of version control.
• The example uses a public RPC; for reliability, use your own provider endpoint.
