Permissionless RWA yield aggregation protocol on Solana.

[Source](https://github.com/anmol0b/Harvester)

## Problem
RWA yield sources on Solana are fragmented across protocols with no permissionless way to aggregate and route capital toward the best available yield.

## Approach
Started as an Anchor program, then rewritten in Pinocchio to cut compute-unit usage. Anchor's account macros are convenient but add CU overhead; Pinocchio's zero-dependency approach meant writing account (de)serialisation by hand, but it kept the account layout byte-identical, so existing state did not need migrating. A Node.js/TypeScript indexer streams on-chain events over Yellowstone gRPC into Postgres, and a Next.js frontend reads from it.

## What I'd do next
- Ship the Pinocchio program to mainnet behind a capped TVL.
- Fan the Yellowstone stream out so the frontend and risk jobs share one feed.

Results

Anchor → Pinocchio rewrite with byte-identical account layouts, so live accounts needed no migration
