Setting BLOCK_NUMBER in your environment before running the fork will aid performance due to better caching. It is recommended to set it to something that hast at least 6 confirmations.
export BLOCK_NUMBER=...
Start the Fork node:
cd contracts
yarn install
yarn run node:fork
You can run tasks against the fork. Make sure to set FORK=true in your environment before running any tasks. For example:
FORK=true npx hardhat debug --network localhost
Additionally, you may need to remove this line from node_modules/hardhat if you experience timeouts running on the fork. Timeouts occur because of how long it takes to retrieve the blockchain state from the provider.
Fund accounts with stablecoins:
cd contracts
FORK=true npx hardhat fund --network localhost

cd dapp
yarn install && yarn run start:fork
