Deploy eSpace Pool Contract

If you want to make your PoS Pool also work for Conflux eSpace users, two more contracts need to be deployed:

  • espace/ESpacePoSPool.sol: The eSpace version of PoSPool.sol contract, deployed in Conflux eSpace.
  • CoreBridge.sol: A bridge contract deployed in Conflux Core Space, which is used to transfer CFX between Core Space and eSpace.

Deploy Contracts

Note: The commands blow are for testnet, if you want to deploy the contracts to mainnet, change the --network parameter to cfxMainnet or espaceMainnet.

Step1. Deploy the CoreBridge contract:

npx hardhat run scripts/core/03_deploy_eSpacePoolBridge.js --network cfxTestnet

After the command runs successfully, you will get the CoreBridge contract address, and add it to .env file as CORE_BRIDGE.

Step2. Deploy the ESpacePoSPool contract in eSpace:

npx hardhat run scripts/espace/01_deploy_pool.js --network espaceTestnet

After the command runs successfully, you will get the ESpacePoSPool contract address, and add it to .env file as ESPACE_POOL_ADDRESS.

Step3. Call setESpacePoolAddress function of CoreBridge contract to set the ESpacePoSPool contract address.

npx hardhat run scripts/core/03_setup_eSpacePoolBridge.js --network cfxTestnet

Step4. Set in PoolManager contract(Optional)

To show eSpace pool in UI, an additional step is required. If you don't use the default UI, you can skip this step.

The default UI require one eSpace pool is corresponding to one Core Space pool, so you need to set the relation in PoolManager contract.

node bin/pool.js PoolManagerSetEspacePool <core-pool-address> <espace-pool-address>

Note: To run this command in a different network, update .env file related variables: CFX_RPC_URL, CFX_NETWORK_ID.

Start the Sync Service

The sync service is used to sync the status between Core Space and eSpace, and transfer CFX between them. It needs to be running all the time.

DEBUG=espacePoolStatusSyncer node service/eSpacePoolStatusSyncer.js

FAQs

Why the deployment script failed or timeout?

Check the CFX balance of the deploy account in both Core Space and eSpace, if it's not enough, you need to transfer some CFX to the account.
