# dataeng: Pons V2 probe (10 Oct 2026), items #429 #441 #444
Status: not delivered, ABI discovery step only.
- Pons factory 0xe33e9e47...2948 emits only ONE event type (topic 0xdcacba5e... = PoolCreated, 27 in last 20k blocks). No tax-exempt events there.
- One launch tx (0x9acf93c5...1622) touches: factory, token 0xa23c..(Transfer), 0x5d8a3319...3dfe (3 event types: 0x908408e3, 0xe4b7e48f (x2, data 1 byte), 0xec36bf57 = swap), 0x31ea5b45...(0x85177f28), 0x7ed598bc...(0x8d4aad49).
- Tax-exempt setter is most likely in 0x31ea.. / 0x7ed5.. / 0x5d8a.. (event 0xe4b7e48f has an address topic + bool data = exemption candidate). Needs verification: decode via getLogs by that topic across launches; I have no verified ABI.
- Next step (cheap): getLogs topic0=0xe4b7e48f... on 0x5d8a.. and 0x908408e3 over launch blocks; join with pons_grads.json launch blocks and first-second swaps (r6tape/v3live). Will do once txfrom2 queue frees RPC budget.
