Problem

We're currently leveraging anchor macros for account validations. Although they are quite convenient and clean to read, we're completely relying on magic macro code to do the most important thing a program should do with regards to security.

Solution

Move all macro account validations into plain ole rust functions called from instruction bodies.

Problem

PDAs can have the same seeds with multiple valid bumps. This means a user could potentially supply a valid PDA derived from the expected seeds but a different address if it was derived using a different bump. Although anchor checks that the supplied PDAs are owned by the program we should add this to avoid loss of funds.

Solution

Save bumps on-chain and validate on along with seeds.

we take a snapshot on the last slot of an epoch and if the next validator didn’t transfer out before the epoch is over then our snapshot balance will be wrong

Build open source API that allows reading tip distribution information using Axum + Rust.

Pls describe how to run test files in mev-programs/tests. Since it's in typescript i can't figure it out.
