@origintrail-official/dkg-chain

Blockchain abstraction layer for DKG V10. Provides a ChainAdapter interface with implementations for EVM chains and testing.

Features

• ChainAdapter interface — unified API for on-chain operations (KC creation, contextGraph management, staking, token transfers)
• EVMChainAdapter — production adapter using ethers.js to interact with deployed DKG smart contracts on EVM chains (Base Sepolia, etc.)
• MockChainAdapter — in-memory mock for local CLI daemon dev mode (type: 'mock'). All CI tests use EVMChainAdapter with Hardhat.
• NoChainAdapter — no-op adapter for workspace/feeless publishing mode where chain interaction is not needed

Usage

import { EVMChainAdapter } from '@origintrail-official/dkg-chain';

const chain = new EVMChainAdapter({
  rpcUrl: 'https://sepolia.base.org',
  privateKey: process.env.PRIVATE_KEY,
  adminPrivateKey: process.env.ADMIN_PRIVATE_KEY,
  hubAddress: '0x...',
});

const tx = await chain.createKnowledgeCollection(merkleRoot, size, epochs);

Internal Dependencies

• @origintrail-official/dkg-core — configuration types, logging
• @origintrail-official/dkg-evm-module — contract ABIs for DKG smart contracts
