Robinhood Chain: Three Things the Docs Don't Say
Originally published on xroot.dev . I spent a day reading Robinhood Chain with eth_call instead of reading about it. Three things turned up that no…
What Your Multisig Threshold Actually Protects
I've been digging into multisig configurations for bridge and protocol security reviews. The threshold gets all the attention — 3-of-5, 4-of-7, what…
Native AA Delayed, ERC-4337 Gets a Reality Check, EOA Migration Debated, Ethereum Drops Poseidon

Why Standard ERC-20 Fails for Real-World Asset (RWA) Tokenization (and How We Solved It with ERC-3643)
When building an Asset Tokenization Platform for Real-World Assets (RWA)—like fractional real estate, private equity, or yield-bearing bonds—the big…
I ran my Solidity scanner on 6 top-audited DeFi protocols. Every 'critical' was a false positive — here's why.
