Substrate asset exchange

A substrate chain created as a learning exercise.

The core pallet is the pallet-asset-exchange which is a uniswap inspired exchange pallet that allows to deposit and withdraw assets and exchange them via various pools. Additionally the pallet-asset-exchange-xcmp implements simple extrinsics to deposit and withdrawal assets from other parachains via cross chain messaging.

Substrate Developer Hub Parachain Template.

Build & Run

To run this follow the steps of the cumulus workshop with this node. 🛠️

Setup

If necessary, refer to the setup instructions at the Substrate Developer Hub.

Build

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

cargo build --release

Run

Local Testnet

Polkadot (rococo-v1 branch):

cargo build --release --features real-overseer

./target/release/polkadot build-spec --chain rococo-local --raw --disable-default-bootnode > rococo_local.json

./target/release/polkadot --chain ./rococo_local.json -d cumulus_relay1 --validator --bob --port 50555
./target/release/polkadot --chain ./rococo_local.json -d cumulus_relay0 --validator --alice --port 50556

Substrate Parachain Template:

# this command assumes the chain spec is in a directory named polkadot that is a sibling of the working directory
./target/release/parachain-collator -d local-test --collator --alice --ws-port 9945 --parachain-id 200 -- --chain ../polkadot/rococo_local.json
