Unable to deploy, max retries...

[effeaucarre]

I have to deploy a program for mainnet, i have tried 2 different RPC (helius & quicknode)

There are around 600 tx to be sent. It takes several minutes to send the 6xx transactions, and i have the error blockhash expired, does this 5 times, then fails.

What could cause this, since it was working like a charm before ?

i'm using "@project-serum/anchor": "^0.24.2" + solana cli 1.15.2

This problem happens because it's getting more and more difficult to land transactions that don't have priority fees in mainnet. Anchor's current deploy logic is a wrapper around solana-cli's deploy, and because solana-cli doesn't yet support setting priority fees, you may get this error.

so is there a better way to deploy the program ? because i'm stuck for many days trying to deploy...
or may be priority fees support will be added in solana cli?

@effeaucarre yes there's a PR to add priority fees to the Solana CLI that should be merged soon. Hold on a sec I'll find it...

Deployment experience is improved in the latest versions of the Solana CLI (after 1.18.12). You usually need to supply different arguments/options to make it work properly though.
