From 6c1f3a0903c69626027d0a39609594cd74b2e0f8 Mon Sep 17 00:00:00 2001 From: dappvibe <57523522+dappvibe@users.noreply.github.com> Date: Mon, 30 Mar 2026 17:01:22 +0000 Subject: [PATCH 1/2] feat: add BuyPexfi ignition module and fix pool tick spacing - Created a new Ignition module `evm/modules/03_BuyPexfi.ts` to buy PEXFI from the v4 pool using 0.0003 ETH. - Updated the tick spacing for the 1% fee pool in `evm/modules/01_Market.ts` from 60 to 200 for consistency. - Added a test case `tests/hardhat/ignition/03_BuyPexfi.test.ts` to verify the module.
