unpause

unpause

The unpause method is integral to the ERC-721 token standard, particularly in contracts implementing the Pausable design pattern. This pattern enables the temporary suspension of specific contract operations, often for administrative or emergency purposes. Upon invocation, the unpause method restores the functionalities previously halted by the pause operation. It forms part of the ERC721Instance object, obtainable through client libraries like ZkyugaClient.

Method Signature

async unpause(signer: WalletSigner): Promise<TransactionResponse>

Parameters

Parameter	Type	Description
signer	WalletSigner	An instance responsible for signing the unpause transaction. This ensures that only authorized entities (such as contract owners or administrators) can resume the paused functionalities of the contract.

Returns

• A Promise resolving to a TransactionResponse object, furnishing comprehensive details about the transaction, including its status, transaction hash, and more.

Usage Example

Begin by obtaining the instance of the desired ERC-721 token contract:

const erc721 = zkyugaClient.getERC721Instance("your ERC-721 contract address here");

Then, utilize the unpause method to restore paused functionalities:

const signer = zkyugaClient.createWalletSigner("your private key here");
const transactionResponse = await erc721.unpause(signer);
console.log(`Transaction Hash: ${transactionResponse.hash}`);

Notes

• Typically, only privileged addresses (such as contract owners or administrators) possess the authority to execute unpause. Ensure that the signer used has the necessary permissions to call this function.

• Always prioritize the security of your private keys. When employing the signer, exercise caution and refrain from exposing private keys in insecure or client-side environments.

• Pausing and unpausing mechanisms serve as crucial tools for contract administration, particularly during emergencies. Keep users or token holders informed about such actions and their implications.
