Bugfix/add solana priority fees

📝 Description

Issue:

https://support.ledger.com/hc/en-us/articles/17531561702813-Temporary-issue-with-Staking-and-Sending-Solana-SOL-in-Ledger-Live-Your-transaction-may-have-failed?support=true

Solution

Advised solution to mitigate this is

• to estimate and add Priority Fee to the transaction to make it accepted by validators faster.
• Calculate and request optimal amount of Compute Units required for tx

Note:

Required getRecentPrioritizationFees rpc call doesn't work correctly in @solana/[email protected].
Hence, @solana/web3.js and @solana/spl-token have been updated.

Looks good 👍

I am no solana expert 😅 Would using lowest value work ?

Hi Hedi
Good question :)
I've been thinking about this as well, and after research it looked like median seem be good to approximate priority fees for a given transaction. This ensures that the priority fees is above the lowest but not too wasteful.

Helius Priority Fee API also uses 50th percentile (median) by default.
But it also provides other values, like low (25th) or UNSAFE_MAX (100th).
