🔁 Steps to Reproduce

1. Go to this liquidity pool, which is set up with tickspacing = 10: https://app.uniswap.org/explore/pools/base/0x870198ffb454503d5ce1b698c94bc98198c874d61e8a2994dd6e01ee04535f89
2. Click on 'Add Liquidity'
3. Inspect the URL's query parameters in the destination URL, expect tickspacing = 10:

https://app.uniswap.org/positions/create/v4
  ?currencyA=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
  &currencyB=0xb1599cde32181f48f89683d3c5db5c5d2c7c93cc
  &chain=base
  &hook=0xBc5F29A583a8d3ec76e03372659e01a22feE3A80
  &fee={"feeAmount":1000,"tickSpacing":60,"isDynamic":true}
  &priceRangeState={"priceInverted":false,"fullRange":true,"minPrice":"","maxPrice":"","initialPrice":""}
  &depositState={"exactField":"TOKEN0","exactAmounts":{}}

---

✅ Expected Behavior

Tick Spacing is correctly set to 10:

&fee={"feeAmount":1000,"tickSpacing":10,"isDynamic":true}

---

❌ Actual Behavior

Tick Spacing set to 60:

&fee={"feeAmount":1000,"tickSpacing":60,"isDynamic":true}

🧾 Additional Context

I still think this correctly adds to the USDC/DCA pool with Tick Spacing 10 since all of my other tools and smart contracts show that it is doing that. My concern is that someone makes a tick spaced pool of 60 and then suddenly liquidity is getting fractured across 2 different pools.

⚠️ Please redact or avoid sharing sensitive data such as private keys, seed phrases, or personally identifying info.

Reproduce the Add Liquidity flow from the linked Base pool and inspect how its tick spacing becomes the /positions/create/v4 URL query parameter. Trace the link and query-parameter construction from that entry point; done means the destination URL preserves tickSpacing=10 for this pool instead of using 60.
