Independent on-chain research: who actually holds admin and multisig keys across DeFi protocols and the Superchain. Cross-referenced on-chain, sourced, methods always committed.

• multisig-overlap, who holds multisig signer keys across multiple, unrelated DeFi protocols at once, checked at three scales: 75+ Ethereum mainnet protocols, Optimism's Superchain (79 protocols, 200 Safes, 13 chains), and now 11 more L2s and L1s (Arbitrum, Polygon, BNB Chain, Avalanche, zkSync Era, Linea, Scroll, Berachain, Mantle, Blast, Sonic). A standing research program, not a one-off snapshot, these figures keep growing.
• onchain-postmortems, independent on-chain forensic reconstructions of DeFi and on-chain exploits, correcting already-published press or DefiLlama figures along the way, over $129M recomputed from primary sources across 16 incidents so far, also standing and growing.

Every claim is checked against a mechanical anti-hallucination / falsifiable-hypothesis process before publication, documented in each repo. No wallets connected, nothing for sale, no affiliation with any protocol covered.

Licensing / custom research: the on-chain verification method behind the multisig-overlap research is available under a commercial license, reach out on X if you want it applied to your own protocol or chain.

Other repos on this account are hackathon entries and unrelated side projects, not part of this research line.
