I’m happy to help you fix your Solana issue. However, I don’t see any code provided in your message. Could you please paste the relevant code snippets or a detailed description of what’s happening?

That said, here are some potential issues and steps that might help resolve the issues you’re experiencing:

Transaction simulation failed

This error usually occurs when Solana is unable to verify the transaction simulation (TS) or load the program. Here are some possible solutions:

• Check the solana show program command: Make sure to replace with the actual ID of the deployed program.

• Check that all keys are synchronized: Make sure that all connected wallets have their keys synchronized with the Anchor wallet. You can check this by running anchor wallet key list.

• Check your file for typos. export.ts: Make sure there are no typos or incorrect variable names that could prevent Solana from loading the program.

Program ID check failed

This error suggests that the program ID you are trying to use is not valid. Here are some possible solutions:

• Check if the program ID is correct: Double check that the program ID you are using is correct and matches the one deployed on localnet.

• Check for typos or incorrect syntax in export.ts: Check that there are no typos or incorrect syntax errors in your export.ts file.

Front-end issues

• Make sure Solana is running in debug mode: Make sure Solana is not running in production mode, as this can prevent certain features from working.

• Check for Solana Web3 provider issues: If you are using a custom web3 provider (e.g. solana-adapter), make sure it is configured correctly and up to date.

Here is an example of what your export.ts file might look like:

import { Keypair } from @solana/web3.js;
import * as anchor from @solana/anchoring.js';
const programId = '...'; // Replace with the current program ID
export async function main() {
const keypair = new keypair();
console.log(keypair);
// Use the keypair to sign a transaction
await solana.showProgram('...'); // This should fail if the program ID is incorrect
}

And here is an example of what your file might look like. export.ts:

import { Keypair } from@solana/web3.js'';
import * as anchor from`@solana/anchoring.js'';
const programId = 'your_program_id_here'; // Replace with the current program ID
export async function main() {
const keypair = new keypair();
console.log(keypair);
// Use the keypair to verify a transaction
await solana.showProgram(programId); // This should work if the program ID is correct
}

Please provide more code snippets or clarify your specific issues and I will do my best to help you further.
