Opening a lootbox

For opening a Lootbox using @lyncworld/lootbox-evm-sdk, you will need to create an instance of LyncLootbox class provided by the SDK and initialize the lootbox instance with a valid lootbox address. Here is an example of creating and initializing a lootbox using the SDK:

import { ChainIdentifier, LyncLootBox } from "@lyncworld/lootbox-evm-sdk";

const lootbox = new LyncLootBox();
const provider = new ethers.providers.Web3Provider(window.ethereum);

const lootboxId = "0x..." // a valid lootbox id created using `createLootBox` method

lootbox
	.initialize(ChainIdentifier.BASE_SEPOLIA, provider, lootboxId)
	.then((response) => console.log(response))
	.catch((err) => console.error("Error in initializing lootbox: ", err));

After creating an instance of LyncLootbox class and intializing, you can utilize the openLootBox method provided by the LyncLootBox class. Here is the complete specification of the method and an example function for creating a new Lootbox:

Method Overview:

The openLootBox function is an asynchronous function that is used to open a loot box. It performs several checks and operations before and after the loot box is opened.

Parameters:

The function takes one parameter:

  • signer (Signer): The signer who will be signing the open loot box transactions. It represents the entity (usually a user) that is initiating the transaction to open the loot box.

  • gasOverrides?: (optional) Gas override parameters (such as gasLimit, gasPrice, and maxFeePerGas from ethers) that you may need to adjust if transactions are failing to go through.

Return Value

The function returns a Promise that resolves to an object with two properties:

  • txn: This is the transaction object returned from the openLootBox function of the lootBoxInstance.

  • receipt: This is the receipt object returned from calling the wait function on the transaction object.

Errors:

The function can throw several errors, all instances of the LootBoxError class:

  • If the Merkle proof validation fails, it throws a LootBoxError with the VALIDATION_ERROR code.

  • If the wallet has no more remaining opens, it throws a LootBoxError with the LOOTBOX_OPENED_ERROR code.

  • If there are too many pending requests, it throws a LootBoxError with the TOO_MANY_REQUESTS_ERROR code.

  • If the loot box opening fails for any other reason, it throws a LootBoxError with the LOOTBOX_OPENED_ERROR code.

NOTE - This function will trigger a transaction on the blockchain, which will require the user to pay gas fees. Make sure the user is aware of this before calling this function. The TransactionResponse object can be used to track the status of the transaction on the blockchain.
