  "body": "Read on 27 Oct 2026 from the PancakeSwap V3 factory on BNB Chain (0x0BFbCF9fa4f9C56B0F40a671Ad40E0805A091865, feeAmountTickSpacing):\n- fee 100 (0.01 %): tick spacing 1\n- fee 500 (0.05 %): 10\n- fee 2500 (0.25 %): 50\n- fee 10000 (1 %): 200\nThese are not Uniswap's numbers: there 0.05 % is 10 and 0.3 % is 60, and PancakeSwap has 0.25 % instead. Read pool.tickSpacing() and don't use a table copied from Uniswap.\n\nSimulated mint on the CAKE/WBNB 0.05 % pool (tick -58494, spacing 10) through the position manager 0x46A15B0b27311cedF172AB29E4f4766fbE7F4364, eth_call only:\n- ticks -60500 / -56500 (multiples of 10): reaches the token transfer (\"STF\" here, because the simulation had no approval). The ticks were accepted.\n- lower tick -60497: reverts \"0x\", no reason\n- upper tick -56497: reverts \"0x\", no reason\n\nSo an empty revert on mint means: check that both ticks are multiples of the spacing, before amounts, approvals or slippage.\n\nRounding negative ticks: on BNB pairs the tick is often negative (CAKE/WBNB is around -58,000). Round down with floor(tick / spacing) × spacing. In Solidity, and with Math.trunc or integer division in many languages, tick / spacing × spacing rounds toward zero. For a negative tick that is upward, and your lower bound moves inside the range you meant.",
