Usage

Create a PerpetualProtocol instance

• Now we only support optimism

const perp = new PerpetualProtocol({
    chainId: 10,
    providerConfigs: [{ rpcUrl: "https://mainnet.optimism.io" }],
})
await perp.init()

Open a position

• Remember to provide your signer when connecting.

For example:

Open a Long position using quoteToken.
baseToken: ETH
quoteToken: USD

const perp = new PerpetualProtocol({
    chainId: 10,
    providerConfigs: [{ rpcUrl: "https://mainnet.optimism.io" }],
})
await perp.init()
await perp.connect({ signer })

const tickerSymbol = "ETHUSD"
const slippage = new Big(0.02) // remember to transform to Big type
const amountInput = new Big(100) // remember to transform to Big type
const side = PositionSide.LONG
const isAmountInputBase = false // we are not using base token to open a long position here.

const newPositionDraft = perp.clearingHouse.createPositionDraft({
    tickerSymbol,
    side,
    amountInput,
    isAmountInputBase,
})
perp.clearingHouse.openPosition(positionDraft, slippage)

Close a position

const tickerSymbol = "ETHUSD"
const position = await perp.positions.getTakerPositionByTickerSymbol(tickerSymbol)
perp.clearingHouse.closePosition(position, slippage)

Add liquidity

• Remember to provide your signer when connecting.

For example:
Use quoteToken to add liquidity.
baseToken: ETH
quoteToken: USD

const perpParam = {
    chainId: 10,
    providerConfigs: [{ rpcUrl: "https://mainnet.optimism.io" }],
}
const perp = new PerpetualProtocol(perpParam)
await perp.init()
await perp.connect({ signer })

const tickerSymbol = "ETHUSD"
const market = perp.markets.getMarket({ tickerSymbol })
const lowerTick = perp.market.getPriceToTick(lowerTickPrice)
const upperTick = perp.market.getPriceToTick(upperTickPrice)

const slippage = new Big(0.02) // remember to transform to Big type

const rawBaseAmount = undefined
const rawQuoteAmount = new Big(100) // remember to transform to Big type

const liquidityDraft = perp.clearingHouse.createLiquidityDraft({
    tickerSymbol,
    rawBaseAmount,
    rawQuoteAmount,
    upperTick,
    lowerTick,
})

perp.clearingHouse.addLiquidity(liquidityDraft, slippage)

Remove liquidity

• ratio means how much ratio you would like to remove. 1 means 100%
• Use filterFn to filter out liquidity you would like to remove.

const ratio = new Big(1) // remember to transform to Big type
const slippage = new Big(0.02) // remember to transform to Big type
const liquidity = perp.liquidities.getTotalLiquidities().filter(filterFn)
perp.clearingHouse.removeLiquidity(liquidity, ratio, slippage)
