When to use

Use this skill when you are:

• Provisioning concentrated liquidity on Uniswap V3 (or V3 forks)
• Reading LP positions, pool state, or uncollected fees
• Writing scripts that add/remove liquidity or collect fees
• Working with tick math, price ranges, or sqrtPriceX96

How to use

• rules/high-value-reads.md - Pool state, positions, fees, tick/price conversions
• rules/execution-opportunities.md - Add/remove liquidity, collect fees
• rules/gotchas.md - Tick math pitfalls, slippage, token ordering, ABIs

Arc V4

Arc (5042) has V4, not V3. Use UniswapAdapter({"chain_id": 5042}, ...) and v4_* methods; V3 NFT/pool calls fail instead of selecting another chain. v4_mint_position accepts a PoolKey, ticks, liquidity and raw amount maxima; v4_increase_liquidity / v4_decrease_liquidity take explicit IDs and limits. v4_collect_fees uses zero-liquidity decrease; v4_close_position burns and returns both currencies to the owner. Persist minted token_ids from receipts. v4_get_positions(ids) reads only those IDs (max 100), with no history scans.

New liquidity supports hookless pools only. Use canonical currency order, aligned ticks and deliberate slippage limits. Native USDC (zero address, 18 decimals) and ERC-20 USDC (0x3600…0000, 6 decimals) are different pool keys but share a wallet balance. Do not normalize one pool into the other. Native input uses msg.value and refunds excess; ERC-20 input uses Permit2.
