DoubleUp SDK

Installation

$ npm install doubleup

Initialization

JS

import { DoubleUpClient } from 'doubleup';

const suiClient = new SuiClient({ url: getFullnodeUrl("mainnet") });

...
export const dbClient = new DoubleUpClient({
    partnerNftListId: "0x0",
    suiClient: provider,
});

React

import { DoubleUpProvider } from 'doubleup';

// or use suiClient from @mysten provider
const suiClient = new SuiClient({ url: getFullnodeUrl("mainnet") });

## Basic Usage

JS

```js
import { Transaction } from "@mysten/sui/transactions";

const txb = new Transaction();
const coinType = "0x2::sui::SUI";
txb.setSender(address);

const betTypes = [0]; // 0 for heads, 1 for tails
const coin = txb.splitCoins(txb.gas, [1_000_000])

dbClient.createCoinflip({
    betTypes,
    coin,
    coinType,
    transaction: txb,
});


// Then just call sign and execute on the txb that is generated

Partner NFTs

The following games are enabled for a reduced house edge for holders of selected NFT projects:

• Range Dice
• Rock, Paper, Scissors

When initializing the client, include the partnerNftListId option or prop.

Then, include partnerNftId in the call to the game. For example:

const dbClient = new DoubleUpClient({
    client: suiClient,
    partnerNftListId: "" // <<<<<<<<<<
});
...

const { ok: gameOk, err: gameErr, gameSeed } = createRangeDice({
    betType,
    coin,
    coinType,
    partnerNftId, // <<<<<<<<<<<<
    range,
    transaction: txb
});

If the player does not own the NFT passed in, then the call to the contract will fail.
