Thomas ranked **#46 out of 7,853 players** on the Goerli leaderboard (top 0.6% globally), with **29 of 30 levels completed**, score 95.50/100, total difficulty faced 258. Only 88 players (1.12%) reached 29+ levels; only 28 (0.36%) completed all 30. Each level completion is enforced on-chain by the Ethernaut factory contract emitting a LevelCompletedLog event after a successful exploit transaction — players can't fake completion. Bonus: OpenZeppelin's own `aliases.json` in the public ethernaut-leaderboard repo maps the holder address to `monproweb.eth` — public attestation by OZ that this address is Thomas's. This is the strongest single signal of smart-contract auditing chops on the entire Quasareum surface.","verifiedVia":"GET raw.githubusercontent.com/OpenZeppelin/ethernaut-leaderboard/update/boards/networkleaderboards/GoerliLeaderBoard.json — search for player=0x42C137538bEe9d7eca612b41A807b5FB7B863C20.
