Prism Chain

Run an Ethereum compatible parachain based on Substrate.

See www.substrate.io for substrate information.

See psm.link for the prism chain description.

Local Development

Follow these steps to prepare a local Substrate development environment 🛠️

Install (linux)

Get the code

Get the master branch of prism：

git clone https://github.com/ShadowsNetwork/prism
cd prism

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
source $HOME/.cargo/env

Run the initialization script, which checks the correct rust nightly version and adds the wasm32-unknown-unknown target to that specific version:

./scripts/init.sh

Build the Prism Node

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

cargo build --release --features "aura"

Run

Single Node Development Chain

Purge any existing dev chain state:

./target/release/prism-node purge-chain --dev

Start a dev chain:

./target/release/prism-node  --dev --ws-external --rpc-external --rpc-cors=all

Or, start a dev chain with detailed logging:

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

if you want to deployment contract on the testnet,this will help you.

TEST

Start a test chain with "manual-seal":

cargo build --release --features "manual-seal"

if you want to test, it is a good idea to use https://hardhat.org/tutorial/

After setting up the hardhat test environment

npx hardhat test
