• Installation
• Usage

Installation

npm i @nftperp/sdk

Also requires ethers library
NOTE: If npm i ethers is used, it will default to installing ethers v6, which will create errors when initialising the SDK

npm i ethers@5

Usage

Setup

import { ethers } from "ethers";
import { SDK } from "@nftperp/sdk";
import { Instance } from "@nftperp/sdk/types";

/**
the general rpc url for arb mainnet is "https://arb1.arbitrum.io/rpc"
recommended using one from infura/alchemy
*/
const provider = new ethers.providers.JsonRpcProvider("<your-rpc-url>");
const wallet = new ethers.Wallet("<your-private-key>", provider);
const nftperp = new SDK({ wallet, instance: Instance.TRADING_COMP });

If an error of the following occurs: SyntaxError: Cannot use import statement outside a module, add in the following to your package.json file

"type": "module"

If an error of the following occurs: Directory import '..\@nftperp\sdk\types' is not supported resolving ES modules, do the following:

// REPLACE
import { Instance } from "@nftperp/sdk/types";
// WITH
import { Instance } from "@nftperp/sdk/types/index.js";

Open a position

import { Amm, Side } from "@nftperp/sdk/types";

const hash = await nftperp.openPosition({
    amm: Amm.BAYC,
    side: Side.BUY,
    amount: 0.1, // 0.1 eth
    leverage: 3,
});

note: to get a list of supported amms do:

console.log(nftperp.getSupportedAmms(Instance.BETA));
/**
[ 'BAYC', 'PUNKS', '...' ]
*/

Get postion

const position = await nftperp.getPosition(Amm.BAYC);

Close position

const hash = await nftperp.closePosition({
    amm: Amm.BAYC,
});

Estimate fee on position

const feeInfo = await nftperp.calcFee({
    amm: Amm.BAYC,
    amount: 1,
    leverage: 1,
    side: Side.BUY,
    open: true, // true for opening pos, false for closing
});

Calculate open position transaction summary

const txSummary = await nftperp.getOpenPosTxSummary({
    amm: Amm.BAYC,
    amount: 1,
    leverage: 1,
    side: Side.BUY,
});

Calculate close position transaction summary

const txSummary = await nftperp.getClosePosTxSummary({
    amm: Amm.BAYC,
    closePercent: 100,
});

Get mark price

const markPrice = await nftperp.getMarkPrice(Amm.BAYC);

Get index price

const indexPrice = await nftperp.getIndexPrice(Amm.BAYC);

Get funding info

const fundingInfo = await nftperp.getFundingInfo(Amm.BAYC);

Get trades

await nftperp.getTrades({ amm: Amm.BAYC, trader: "<trader-address>" });
await nftperp.getTrades({ from: 1680307200, to: 1682899200, sort: Sort.ASC });
await nftperp.getTrades({ hash: "<transaction-hash>" });

    ]
}

Get fundings

await nftperp.getFundings({ amm: Amm.BAYC });
await nftperp.getFundings({ from: 1680307200, to: 1682899200, sort: Sort.ASC });
await nftperp.getFundings({ hash: "<transaction-hash>" });

        },

Streamer

Stream realtime events! directly consume parsed event data!

import { EVENT } from "@nftperp/sdk/types";

nftperp.on(EVENT.TRADE, (data) => console.log(data));
/**
{
    "trader": ...,
    "amm": ...,
    "margin": ...,
    "exchangedPositionNotional": ...,
    "exchangedPositionSize": ...,
    "fee": ...,
    ...
}
*/

nftperp.on(EVENT.FUNDING, (data) => console.log(data));
/**
{
    "amm": ...,
    "markPrice": ...,
    "indexPrice": ...,
    "fundingRateLong": ...,
    "fundingRateShort": ...,
    ...
}
