Local Development

Follow these steps to prepare a local Substrate development environment 🛠️

Simple Setup

Install all the required dependencies with a single command (be patient, this can take up to 30 minutes).

curl https://getsubstrate.io -sSf | bash -s -- --fast

Manual Setup

Find manual setup instructions at the Substrate Developer Hub.

Build

Once the development environment is set up, build the node. This command will build the Wasm and native code:

cargo build --release

Run

Single Node Development Chain

Purge any existing dev chain state:

./target/release/hack-hydra-dx purge-chain --dev

Start a dev chain:

./target/release/hack-hydra-dx --dev

Or, start a dev chain with detailed logging:

RUST_LOG=debug RUST_BACKTRACE=1 ./target/release/hack-hydra-dx -lruntime=debug --dev

Interaction with the node

Go to the polkadot apps at https://dotapps.io

Then open settings screen -> developer and paste

NOTE - FixedU128 type is not yet implemented for polkadot apps. Balance is a measure so price can be reasonably selected. If using polkadot apps to create pool:

• 1 Mega Units equals 1:1 price
• 20 Mega Units equals 20:1 price
• 50 Kilo Units equals 0.05:1 price
