Follow these steps to prepare a local development environment 🛠️

Rust development environment.

Checkout code

git clone --recursive https://github.com/Kylin-Network/kylin-node.git

Build debug version

cd kylin-node
cargo build

Build release version

cd kylin-node
cargo build --release

Build debug version

docker build -f Dockerfile -t kylin-node .
docker run -p "9944:9944" -p "9933:9933" -p "9615:9615" -p "30333:30333" kylin-node:latest bash -c "/kylin-node --dev --ws-external --rpc-external --rpc-methods Unsafe"

Using Kylin Market Front End which can be used to interact with Kylin Node.

git clone https://github.com/Kylin-Network/kylin-market-frontend.git
cd ./kylin-market-frontend
yarn install

Purge any existing dev chain state:

./target/debug/kylin-node purge-chain --dev

Start a dev chain:

./target/debug/kylin-node --dev

or, start a dev chain with detailed logging:

RUST_LOG=debug RUST_BACKTRACE=1 ./target/debug/kylin-node -lruntime=debug --dev

replace debug with release.

Caution! Donot try to run release version everytime, it will take lots of time.

visit https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/settings/developer.

fill the config in Settings>>Developer.

{
  "Address": "<AccountId>",
  "LookupSource": "<AccountId>",
  "DataInfo": {
    "url": "Text",
    "data": "Text"
  }
}

Run ./scripts/insert_alice_key.sh to insert OCW signer. If the OCW signer does not have enough balance, please charge money as following instructions.

Select Developer>>Extrinsics, then using priceFetchModule.addFetchDataRequest(url), type a url encode hex format.

Select Developer>>Chain state, then using priceFetchModule.requestedOffchainData(u64), press +.
