node issue

[SkullCandby]

I tested this code with my decent QuickNode rpc endpoint (the one for) and it did not work (block height exceeded.), but it works with public main node. Any advices on what node I should get?

Hi, as far as I know there are a few things you can do for tx inclusion and those are as follows:

• Up priority fee (increases chance of inclusion if the tx reaches the validator)
• Send identical tx multiple times (increases change of tx reaching validator)
• Bundle tx instead through jito
• Get your own node/ paid tier of quicknode or helius

But I'm not an expert on transaction inclusion so there will be others more qualified to answer this

I have my own node bought from QuickNode. Also, I was using pumpportal api before with node and when I was sendim txs in the loop moneys were always debited for JITO in every failed transaction

If you bundle it yourself with a jito tip in the transaction, you will not pay the tip unless it executes.

but it takes like 3 minutes to buy a token

[bilix-software]

What are you using as priority fee? Have you tried upping that?

[SkullCandby]

0.01, but does it affect transaction speed if I am the only one who is buying a token

[bilix-software]

Well it does affect inclusion rate, for the validator it doesnt matter what your transaction is doing. But 0.01 is already very high so i would not increase that further. Have you recompiled the typescript (npx tsc), after making changes in the example.ts file?

[SkullCandby]

no I just recompiled it using npx tsc
