aidez-moi à accélérer la transaction Solana
`async sendSplTransaction(wallet, {to, valeur, mintAddress, décimales, frais}) {

const mintPubKey = new PublicKey(mintAddress);
const bigValue = this.convertToBigInt(valeur, décimales);
const recentBlockhash = attendre this.provider.connection.getLatestBlockhash();
laissez currentBlockheight = attendre this.provider.connection.getBlockHeight();
const { blockhash } = attendre this.provider.connection.getLatestBlockhash();
const MAX_RETRIES = 3;
laissez retryCount = 0;

    while (retryCount  setTimeout(resolve, delay));
