An open-source static analyzer for TON smart contracts written in Tact, with 42 built-in detectors that flag errors and risky patterns before deployment; installing Souffle unlocks extra detectors. Free and Apache-2.0. Its README names only Tact, not FunC or Tolk, and it tracks each Tact release, so match it to your compiler version.

Chain support, with sources

We only add a chain when the maker's own docs name it. "EVM-compatible" alone counts for no specific chain. A testnet-only record means the page we checked only shows testnet; it isn't a finding that mainnet is unsupported. This is what the docs say, not a test or security review.
