Params

// create new params object
const params = {"rpc":"your helius rpc endpoint"} 
// false = you're expecting a normal signable transaction
// true = you're expecting base64 for a Blink
params.blink = false; // (omit||default = false)
// false = you're passing fractionalized units when creating
// true = you're passing decimal values when creating
params.convert = false; // (omit||default = false)
// Fee Priority Options = VeryHigh, High, Medium, Low, Min
params.priority = "Low"; // (omit||default = "Low")

Simple NFT Sale

Selling a Core NFT for 1.0 SOL

Every OTC Contract has a "seller" and a "buyer"

import mcswap from 'mcswap-js'; // import module
const params = {"rpc":"your helius rpc endpoint"} // create new params object
params.blink = false; // return signable tx
params.convert = true; // use decimals instead of fractional units
params.priority = "Medium"; // fee priority
params.seller = "7Z3LJB2rxV4LiRBwgwTcufAWxnFTVJpcoCMiCo8Z5Ere"; // seller wallet
params.sellerMint = "56nFoG781ZksKWEyJF5vs5H8Fq3S491EJM3BAogCqRBi"; // seller nft
params.buyer = "2jcih7dUFmEQfMUXQQnL2Fkq9zMqj4jwpHqvRVe3gGLL"; // buyer wallet
params.lamports = 1.0; // SOL - using decimals via convert
const tx = await mcswap.coreCreate(params); // build the tx
const signed = await provider.signTransaction(tx); // sign the tx
const signature = await mcswap.send(signed); // send the tx
const status = await mcswap.status(signature,10,2); // wait for finalization
if(status!="finalized"){console.log({"status":"error","message":status});return;}
console.log({"status":"ok","message":"contract created!"});

Non-Fungible Assets

Sell a Non-Fungible Asset for one or more of the following:

• A NFT of the same Standard

• A SPL or Token2022 Token

• SOL

Fees

The following fetches the current protocol fees

// Get PIKL fee for the McSwap SPL txs (Fungible)
params.standard = "spl";
console.log(await mcswap.fee(params));
// Get SOL fee for McSwap NFT txs (Non-Fungible)
