About Primus Network-Core-SDK

When integrating data verification solutions into your backend server, you can utilize the Primus Network Core SDK.

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

Copy .env.example to .env in the project root:

cp .env.example .env

Then set your PRIVATE_KEY:

PRIVATE_KEY=0xYOUR_PRIVATE_KEY

and

CLIENT_KEY and CLIENT_CRT for mTLS:

CLIENT_KEY=/path/to/your/client/key
CLIENT_CRT=/path/to/your/client/cert

• CLIENT_KEY: the client private key file, in PEM format (e.g. -----BEGIN PRIVATE KEY-----...).
• CLIENT_CRT: the client certificate file, in PEM format (e.g. -----BEGIN CERTIFICATE-----...).

Security note: keep the client key private and stored securely; never commit it or share it publicly.

Customize

Edit these sections in index.js:

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

Run

node index.js

You should see logs for:

• submit task result
• attest result
• task result

Notes

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