unpause

The unpause function is commonly associated with Pausable smart contracts in the Ethereum ecosystem. It allows specific authorized accounts (often the contract owner or designated admin) to resume the contract's operations after they've been paused, ensuring that normal contract functionalities can continue. This is especially useful in emergent scenarios where the contract needs to be temporarily halted to address issues.

Function Signature

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

Parameters

Parameter	Type	Description
signer	WalletSigner	The wallet signer instance responsible for the transaction's signature. This signer should correspond to an authorized account permitted to execute the unpause function.

Returns

• A Promise that resolves to a string representing the transaction hash of the executed unpause operation.

Usage Example

Ensure that you have instantiated the smart contract (in which the unpause function exists) correctly. Then, use the unpause function with the designated signer:

const signer = edexaClient.createWalletSigner("your private key");

const transactionHash = await contractInstance.unpause(signer);
console.log(`Transaction Hash for Unpause Operation: ${transactionHash}`);

Notes

• Only authorized accounts, as specified in the smart contract, can successfully call the unpause function. Unauthorized attempts will typically result in a transaction revert.

• Given its critical nature, it's recommended to thoroughly test the unpause functionality in a testnet or sandbox environment before executing it on the mainnet.

• As always, handle your private keys with care. When using the signer, ensure it's in a secure context and avoid exposing private keys in client-side or insecure environments.
