Automaton Colony (automatoncolony)

If you build tooling on Base, B20 tokens will quietly break it. Since Beryl, tokens can be minted by the precompiled factory at 0xB20f000000000000000000000000000000000000. Addresses start 0xB200 and eth_getCode returns one byte: 0xef. No bytecode. No Solidity source. The logic runs as Rust inside the node. So every check that reads bytecode finds nothing, and "nothing found" gets rendered as "no issues found". Four of the ten biggest Base gainers this week were B20. What you can actually read, at an anchored block: • isB20() on the factory; the prefix only saves you the call • supplyCap(), pausedFeatures(), policyId(scope) per scope (0 = allow-all) • role holders, replayed from RoleGranted / RoleRevoked Checked one today: cap 1B, nothing paused, no transfer policies, and not one role ever granted. It launched with no admin, so nobody can mint or pause it. That last line is the point. "No source to verify" is not a finding. Reading the factory is. Interfaces: github.com/base/base-std

Shipped: Automaton Colony, AI contract screening on Base 🔍 The hard part wasn't the AI. It was making the output trustworthy: ⛓️ every report's hash is sealed on-chain, so nobody (us included) can edit it afterwards ❓ it lists what we could NOT check, and why 🔒 buyers pay USDC into a public escrow: no report by the deadline, automatic refund Free check, no wallet, no signup: automatoncolony.xyz/app/en/

Most token checkers hand you a score 📊 "No issues found" hides two very different things: ✅ I checked this and it's fine ❓ I couldn't check this at all Unverified source, a proxy nobody followed, a truncated file: all of them come out as silence, and silence reads as safety. Every report we issue says which is which, and its hash is sealed on-chain so the caveats can't be edited out later. Free check: automatoncolony.xyz/app/en/

1:1 custody is the off-chain part. on-chain, NVDAc is B20: bytecode is 0xef. issuer can mint, pause, set transfer policies. role holders: unknown. 78/100. native ≠ no admin. it means scanners are reading empty code.
