Transaction simulation failed: Error processing Instruction 0: instruction changed the balance of a read-only account

Question

I wrote a function in typescript by using solana/web3.js. Sometimes, I received this error. I simply implement code following the doc of solana. I realized if I use sendRawTransaction, it will be better result, the failure percentage is quite lower than sendTransaction.

const amount = this.convertSOL2LAMPORT(request.amount).toNumber()
const transaction = new solanaWeb3.Transaction().add(
  solanaWeb3.SystemProgram.transfer({
    fromPubkey: signerKeyPair.publicKey,
    toPubkey: new solanaWeb3.PublicKey(request.to),
    lamports: amount,
  }),
)

const result = await this.provider.sendTransaction(
  transaction,
  [signerKeyPair],
  {
    /**
     * * Base on retry transaction fact
     * * https://solanacookbook.com/guides/retrying-transactions.html#facts
     */
    maxRetries: 5,
  },
)

P/s: I'm using third party api (which is Quicknode for testnet and GetBlock for mainnet).

Answer 1

Frompubkey and topubkey should be wallet address and you also need to give recent blockhash and fee payer to all the transaction object

Answer 2

I found a unoffical solution that send multiple transaction with the same hashTx. Many error returned but the success result responsed together. I thought this is potent
