Tutorial code for Levana Perps

Getting started

1. Copy env.sample to .env and set your seed phrase
2. In typescript, run npm install
3. Edit typescript/src/config.ts to have the correct factory address

Examples

In typescript, run any of the available commands (see them in package.json).

• open-close-position: deposits liquidity, opens a position, closes the position, withdraws liquidity (unless in cooldown).
• crank-until-finished: runs the crank until there's no more crank work
• show-price: shows both the live potential spot price and the last spot price pushed into the contract
• show-collateral: shows the collateral balance and information about the collateral token
• show-tvl: shows the collateral balance and information about the collateral token

You must supply a networkId of either sei-testnet or osmosis-testnet, and a marketId for all except show-tvl. NPM syntax requires these after a --

So for example, from in the typescript directory, here's how to run the open-close-position script on Sei testnet and the BTC_USD market:

npm run open-close-position -- --networkId="sei-testnet" --marketId="BTC_USD"

And here's how to do the same thing on Osmosis testnet and the ATOM_USD market:

npm run open-close-position -- --networkId="osmosis-testnet" --marketId="ATOM_USD"

And to calculate TVL for Osmosis mainnet

npm run show-tvl -- --networkId="osmosis-mainnet"

Of course, feel free to modify any of this as needed, the purpose of this repo is educational or to bootstrap your own custom project. Go for it!
