permanent storage

At present, our transaction pool uses dashmap as memory storage, but as a centralized bundler (currently), it actually needs to permanently store the transactions in the current transaction pool. It would be perfect if added to permanent storage.

That's a good point. For the user operation pool, you can already use database implementation (https://github.com/Vid201/aa-bundler/blob/main/crates/uopool/src/database/mempool.rs) which stores the mempool on the disk (replace MemoryMempool here https://github.com/Vid201/aa-bundler/blob/main/crates/grpc/src/uopool.rs#L339). We don't have the same implementation for reputation part yet.

But it would make sense to switch default implementation to database instead of memory. Let me create issue for that.

Great job!
