Ethereum: “getting” promise {
As a Developer Building Smart Contracts On The Ethereum Blockchain Using the Popular Hardhat Framework, You May Encounter Difficulties Deploying Your Contract. One common issue is Encountering an error response that the deployment was successful but not actual deployed yet (i.e., it’s in a pending state).
In this article, we’ll explore why might be happening and how to resolve it.
What does “pending” mean?
When you use ethers.get contract factory (). Deploy (), hardhat creates an ethereum smart contract factory that allows you to deploy contracts on the blockchain. The contract is Built Using Solidity, A Programming Language Used For Writing Smart Contracts On The Ethereum Network.
In Some Cases, your deployment script May not finish building and deploying the contract in time before it’s called by other code. This can cause issues when trying to access or interact with the deployed contract.
Why is my contract still “pending”?
There are Several Reasons Why Your Contract Might Be Stuck in a Pending State:
- Transaction Timeout
: If a transaction takes longer than expected to complete, hardhat may reject it and delay the deployment process.
- Contract Building Issues : Sometimes, Building Contracts Can Take A While, Especular If You’re Using Advanced Settings or Complex Code.
- Network Congestion : If multiple nodes are trying to deploy contracts at the same time, Network Congestion Can Cause Delays.
Resolving the Issue
To Resolve This Issue, Follow these Steps:
1. Check for transaction timeouts
If your deployment script is Too Long to Build and Deploy the contract, Hardhat May Reject It. You can check if transactions are timed out by examining the transactionhash output of theget contracting factory () deploy ()call.
`Javascript
Const factory = ethers.get contract Factory (‘BinaryvillerobotsSnft’);
conste deployment = await factory.depoy ();
Concantationhash = Await deployment.wait ();
// Check If Transaction was Timed Out
IF (Transactionhash && transactionhash.timestamp
// Handle Timeout Error
} Else {
// Deployment Successful, But Contract Still Pending
}
`
2. Optimize your deployment script
To speed up deployment times:
- Reduce the Complexity of Your Solidity Code.
- Use a more efficient build configuration.
- Minimize the number of Dependencies.
3. Check for Network Congestion
If multiple nodes are trying to deploy contracts at the same time, consultant a distributed deployment strategy or optimizing your contract’s build process to reduce contention on the network.
4. Handle timeouts explicitly
Instead of Relying on Wait () to handle timeouts implicity, you can use a timeout callback function:
`Javascript
Const factory = ethers.get contract Factory (‘BinaryvillerobotsSnft’);
ConstePoyMent = Await Factory.depoy ({
// other parameters …
}, (error: any) => {
IF (Error && Error.code === 8) {
// deployment Timed Out
} Else {
// Deployment Successful, But Contract Still Pending
}
});
