Priority Fee during this congested period.

[metarsit]

Context (TLDR;)

• I am trying to improve my send function for Solana
• With the recent transaction spike, not many of my transaction is completed
• Hoping to find a better way for this with this library

Current code

    limit := computebudget.NewSetComputeUnitLimitInstruction(500000).Build()
    feesInit := computebudget.NewSetComputeUnitPriceInstructionBuilder().
        SetMicroLamports(3000).Build()

    trf := system.NewTransferInstruction(
        bigAmt.Uint64(),
        accountFrom.PublicKey(),
        accountTo,
    ).Build()

    log.Info("Creating Transaction")
    tx, err := solana.NewTransactionBuilder().
        AddInstruction(feesInit).
        AddInstruction(limit).
        AddInstruction(trf).
        SetRecentBlockHash(recent).
        SetFeePayer(accountFrom.PublicKey()).
        Build()
    if err != nil {
        return errors.Wrap(err, "unable to create new transaction")
    }

Some help I may need

1. Did I use the wrong value for the limit and fee? (I followed #166)
2. Is there a better way to build this transaction before signing and sending it?

I really appreciate any help you can provide. I am pretty new to this and hope I can get a kickstart on this. Thank you very much.

@metarsit IMO official doc and Helius article are the best for kicking-off.

Your code looks good to me. You're trying to set the prioritization fee as 6_500 Lamports in your example.

500_000 * 3_000  * 0.000001 + 5_000 = 6_500

where: 500_000 - compute unit limit 3_000 - compute unit price 0.000001 - convert microlLamports to Lamports 5_000 - base fee in Lamports

If you can't land your tx with 6_500 Lamports, current commissions may be higher due to congestion.

I'd suggest using getrecentprioritizationfees RPC method to understand the current market condition. And here is an example of the call in this SDK

Thank you for a great share on the information @0xvbetsun! I understand this a bit better now. However, I have tried to set even crazier fee but the success rate is still very low. Is there any other way to improve the success rate?

[0xvbetsun]

You're welcome, @metarsit I don't, actually, have a super-secret technique to achieve a 100% landing rate. Just a well-known recommendations:

• Skipping preflight
• Handling retries client side
• Minimizing compute units
• Adding priority fees

Here is a page from Tritone One with those recommendations

Also, you can get some inspiration for how to send tx directly to the current leader from Helius Atlas

Thanks both! I will apply these changes! ❤️
