Start Local Dev Chain

Init a dev chain using the test account that has 20 billions of CKB tokens in the genesis block.

bin/init-dev-chain.sh

Import the test account into ckb-cli with empty password

echo 'd00c06bfd800d27397002dca6fb0993d5ba6399b4238b2f29ee9deb97593d2bc' > specs/miner.key
ckb-cli account import --privkey-path specs/miner.key </dev/null

Start the chain.

ckb run

Generate some blocks to make the CKB tokens in the genesis block available.

bin/generate-blocks.sh 20

Deploy Contracts to the Local Dev Chain

Download contract cells

bin/download-contracts.sh

Deploy using ckb-cli by running the following script

bin/deploy-to-dev-chain.sh

This will create the .env file which contains the configurations for the dev chain. To switch back to the testnet, just rename the .env file or delete it.

Configure The Web App

Start the local development server.

pnpm dev

Connect a wallet and copy the CKB address displayed at the top of the page.

Transfer some CKB tokens from the miner account to the copied address. Replace ckbt1qz... with the real address in the following command.

bin/dev-faucet.sh ckt1qz...

Mine some blocks to commit the transfer transaction.

bin/generate-blocks.sh 3

Now it's OK to run the web app with the local dev chain. Start a dev miner process in another terminal window to commit transactions automatically:

bin/run-dev-miner.sh

Or run bin/generate-blocks.sh 3 to commit transactions manually.

To test the phase 2 withdraw, use the command bin/generate-epochs.sh 180 to generate 180 epochs, which is a full DAO cycle.

bin/generate_epochs.sh 180
