token-allowance

No strong indicators of covert malware (no obfuscation, no persistence, no arbitrary outbound exfiltration beyond the configured RPC). The primary security concerns are operational and high-privilege: it can sign and broadcast ERC-20 approve/revoke transactions using raw private key material (high impact if misused) and it performs an unpinned runtime pip install of 'web3' when imports fail (supply-chain/provenance risk). Treat this module as sensitive and restrict who/what can call it and where dependencies are resolved.
