🚀 What We Achieved in M1
🔹 1. KARX Token Contract (XRC-20) Deployed on XDC Mainnet
The KARX token now powers all operations inside the KARXChain ecosystem.
- Every Digital Product Passport action (publish/update) uses KARX as a fee token, enabling:
- On-chain fee enforcement
- Automatic burn mechanics
- Transparent usage accounting via XDCScan
Contract Address:
https://xdcscan.com/token/0x8f864122aec1908855ce9bab1bd46356c2372237
🔹 2. DPP Data Storage Smart Contract Deployed
We completed and deployed our Data Storage Contract, which anchors every Digital Product Passport (CID + hash) to the XDC Mainnet.
Supported methods include:
- publishDpp(prefix, uid, cid, hash)
- updateDpp(prefix, uid, cid, hash)
- fetchDataHash(prefix, uid)
This contract ensures every product passport has a verifiable, tamper-proof on-chain reference.
🔹 3. Fully Functional Integration With karx.org
Our public platform karx.org is now integrated directly with XDC, allowing:
- Super Admin → Tenant creation
- Tenants → Publish DPPs
- Customers → Search & verify DPP authenticity
All DPP lifecycle operations seamlessly interact with XDC Mainnet via Nethereum and our integrated contracts.
🔹 4. XDC-Compatible Private Subnet is Live
We launched our first XDC-compatible Private Subnet, enabling:
- Faster iteration for DPP features
- Brand-specific isolated environments
- Future custom token deployments for consortiums
- Seamless bridging into XDC Mainnet
This subnet forms the foundation for enterprise-level deployments of KARX-powered DPPs.
