Hubble Protocol

Hubble is a DeFi protocol on Solana. Before its contracts held real value, they needed to be attacked at speed.

• A native Solana runtime harness so that contracts could be fuzzed in-process with honggfuzz, orders of magnitude faster than through a validator.
• Technical fuzzing for crashes and invariant violations; financial fuzzing for sequences of trades and liquidations that could drain value.
