Uniswap V4 LP Skill

Provide liquidity on Uniswap V4 pools on Base — create positions, increase/decrease liquidity, and collect fees.

CRITICAL RULES

1. ONE TASK AT A TIME. Only do the work described in the CURRENT task. Do NOT work ahead.
2. Do NOT call say_to_user with finished_task: true until the current task is truly done.
3. Sequential tool calls only. Never call two tools in parallel when the second depends on the first.
4. Use exact parameter values shown. Especially cache_as values — use exactly what is specified.
5. Always use WETH, not native ETH. If the user wants to LP with ETH, wrap it to WETH first using the weth_deposit preset.

Pool Configuration

Token0/token1 order is determined by address sort (lower address first). WETH < STARKBOT by address.

Key Addresses (Base)

Tick Range Guidance

When creating a position, the user must choose a tick range. Offer these options:

• Full range: tickLower = -887200, tickUpper = 887200 (like V2, simple but less capital efficient)
• Wide range: approximately ±50% around current tick (balanced risk/efficiency)
• Narrow range: approximately ±10% around current tick (high capital efficiency, more IL risk)

Tick alignment: tickLower and tickUpper must be multiples of the pool's tick spacing (200 for STARKBOT/WETH). Round to the nearest multiple.

To compute ticks from price ratios around the current tick:

• For ±X% range: tickLower = currentTick - (X_ticks), tickUpper = currentTick + (X_ticks)
• Round both to nearest multiple of tickSpacing (200)

Operation A: Get Pool Info

Read pool state to get current tick, price, and liquidity. No tasks needed — just direct tool calls.

A1. Select network

{"tool": "select_web3_network", "network": "base"}

A2. Read pool slot0

{"tool": "web3_function_call", "abi": "uniswap_v4_state_view", "contract": "0xa3c0c9b65bad0b08107aa264b0f3db444b867a71", "function": "getSlot0", "params": ["0x0d64a8e0d28626511cc23fc75b81c2f03e222b14f9b944b60eecc3f4ddabeddc"], "call_only": true}

Returns: sqrtPriceX96, tick, protocolFee, lpFee.

A3. Read pool liquidity

{"tool": "web3_function_call", "abi": "uniswap_v4_state_view", "contract": "0xa3c0c9b65bad0b08107aa264b0f3db444b867a71", "function": "getLiquidity", "params": ["0x0d64a8e0d28626511cc23fc75b81c2f03e222b14f9b944b60eecc3f4ddabeddc"], "call_only": true}

A4. Calculate and report

Calculate approximate price from sqrtPriceX96:

• price = (sqrtPriceX96 / 2^96)^2
• Adjust for decimals: WETH has 18 decimals, STARKBOT has 18 decimals
• This gives STARKBOT per WETH price

Report: current tick, sqrtPriceX96, liquidity, approximate price.

Operation B: Create Position (Deposit) — 5 Tasks

Define tasks

{"tool": "define_tasks", "tasks": [
  "TASK 1 — Prepare: select Base, look up both tokens, check balances, read pool state (slot0 + liquidity). See LP skill 'Task 1'.",
  "TASK 2 — Approve: approve both tokens for Permit2 (skip if sufficient). See LP skill 'Task 2'.",
  "TASK 3 — Build tx: POST to Uniswap API /lp/create, cache response. See LP skill 'Task 3'.",
  "TASK 4 — Execute: decode calldata, call LP preset, then broadcast_web3_tx. See LP skill 'Task 4'.",
  "TASK 5 — Verify the LP position result and report to the user. See LP skill 'Task 5'."
]}

Task 1: Prepare — look up tokens, check balances, read pool state

1a. Select network

{"tool": "select_web3_network", "network": "base"}

1b. Look up WETH (token0)

{"tool": "token_lookup", "symbol": "WETH", "cache_as": "sell_token"}

1c. Check WETH balance

{"tool": "web3_preset_function_call", "preset": "weth_balance", "network": "base", "call_only": true}

1d. Look up STARKBOT (token1)

{"tool": "token_lookup", "symbol": "STARKBOT", "cache_as": "sell_token"}

1e. Check STARKBOT balance

{"tool": "web3_preset_function_call", "preset": "erc20_balance", "network": "base", "call_only": true}

Note: sell_token register now holds STARKBOT address (from 1d). The erc20_balance preset reads from token_address — you need to set it:

{"tool": "token_lookup", "symbol": "STARKBOT", "cache_as": "token_address"}

Then check balance:

{"tool": "web3_preset_function_call", "preset": "erc20_balance", "network": "base", "call_only": true}

1f. Read pool state

{"tool": "web3_function_call", "abi": "uniswap_v4_state_view", "contract": "0xa3c0c9b65bad0b08107aa264b0f3db444b867a71", "function": "getSlot0", "params": ["0x0d64a8e0d28626511cc23fc75b81c2f03e222b14f9b944b60eecc3f4ddabeddc"], "call_only": true}

{"tool": "web3_function_call", "abi": "uniswap_v4_state_view", "contract": "0xa3c0c9b65bad0b08107aa264b0f3db444b867a71", "function": "getLiquidity", "params": ["0x0d64a8e0d28626511cc23fc75b81c2f03e222b14f9b944b60eecc3f4ddabeddc"], "call_only": true}

1g. Report and suggest tick range

Report balances, current tick, price, and liquidity. Suggest tick ranges (full/wide/narrow). Ask user to confirm amounts and range. Complete with finished_task: true.

Task 2: Approve tokens for Permit2

Uniswap V4 uses Permit2. Check and approve BOTH tokens if needed.

2a. Check WETH allowance for Permit2

{"tool": "token_lookup", "symbol": "WETH", "cache_as": "sell_token"}

{"tool": "web3_preset_function_call", "preset": "erc20_allowance_permit2", "network": "base", "call_only": true}

2b. Approve WETH if needed

If allowance is insufficient:

{"tool": "web3_preset_function_call", "preset": "erc20_approve_permit2", "network": "base"}

{"tool": "broadcast_web3_tx", "uuid": "<uuid>"}

Wait for confirmation.

2c. Check STARKBOT allowance for Permit2

{"tool": "token_lookup", "symbol": "STARKBOT", "cache_as": "sell_token"}

{"tool": "web3_preset_function_call", "preset": "erc20_allowance_permit2", "network": "base", "call_only": true}

2d. Approve STARKBOT if needed

If allowance is insufficient:

{"tool": "web3_preset_function_call", "preset": "erc20_approve_permit2", "network": "base"}

{"tool": "broadcast_web3_tx", "uuid": "<uuid>"}

Wait for confirmation.

2e. Complete

{"tool": "task_fully_completed", "summary": "Both tokens approved for Permit2. Ready to create position."}

If both were already approved:

{"tool": "task_fully_completed", "summary": "Both tokens already approved for Permit2 — skipping."}

Task 3: Build LP transaction via Uniswap API

IMPORTANT: Use the pool state values from Task 1 (currentTick, sqrtRatioX96, poolLiquidity).

Convert amounts to raw units first:

For WETH (token0, 18 decimals):

{"tool": "to_raw_amount", "amount": "<weth_amount>", "decimals": 18, "cache_as": "lp_amount0"}

For STARKBOT (token1, 18 decimals):

{"tool": "to_raw_amount", "amount": "<starkbot_amount>", "decimals": 18, "cache_as": "lp_amount1"}

Then call the Uniswap API:

{
  "tool": "web_fetch",
  "url": "https://trade-api.gateway.uniswap.org/v1/lp/create",
  "method": "POST",
  "headers": {"x-api-key": "$UNISWAP_API_KEY"},
  "body": {
    "protocol": "V4",
    "walletAddress": "<wallet_address>",
    "chainId": 8453,
    "position": {
      "pool": {
        "token0": "0x4200000000000000000000000000000000000006",
        "token1": "0x587Cd533F418825521f3A1daa7CCd1E7339A1B07",
        "fee": 10000,
        "tickSpacing": 200,
        "hooks": "0x0000000000000000000000000000000000000000"
      },
      "tickLower": "<tick_lower>",
      "tickUpper": "<tick_upper>"
    },
    "amount0": "<raw_amount0_from_register>",
    "amount1": "<raw_amount1_from_register>",
    "poolLiquidity": "<from_task1>",
    "currentTick": "<from_task1>",
    "sqrtRatioX96": "<from_task1>",
    "slippageTolerance": 50
  },
  "extract_mode": "raw",
  "cache_as": "uni_lp_tx",
  "json_path": "create"
}

The json_path: "create" extracts the transaction object from the API response's create field. The cached register will contain {to, data, value}.

After success:

{"tool": "task_fully_completed", "summary": "LP create transaction built and cached. Ready to execute."}

Task 4: Decode and execute LP transaction

4a. Decode the cached transaction

{"tool": "decode_calldata", "abi": "uniswap_v4_position_manager", "calldata_register": "uni_lp_tx", "cache_as": "uni_lp"}

This extracts uni_lp_contract, uni_lp_param_0, uni_lp_param_1, uni_lp_value from the cached transaction.

4b. Execute via preset

{"tool": "web3_preset_function_call", "preset": "uni_v4_modify_liquidities", "network": "base"}

4c. Broadcast

{"tool": "broadcast_web3_tx", "uuid": "<uuid>"}

The task auto-completes when broadcast_web3_tx succeeds.

Task 5: Verify

{"tool": "verify_tx_broadcast"}

Report the result:

• VERIFIED: Position created successfully. Report tx hash and explorer link.
• REVERTED: Transaction failed. Tell the user.
• TIMEOUT: Tell user to check explorer.

{"tool": "task_fully_completed", "summary": "LP position created successfully."}

Operation C: Increase Position — 4 Tasks

Used to add more liquidity to an existing position.

Define tasks

{"tool": "define_tasks", "tasks": [
  "TASK 1 — Prepare: select Base, look up tokens, check balances, read pool state. Get tokenId from user. See LP skill 'Increase Task 1'.",
  "TASK 2 — Approve: approve both tokens for Permit2 (skip if sufficient). See LP skill 'Task 2' (same as create).",
  "TASK 3 — Build + Execute: POST to /lp/increase, decode, execute, then broadcast_web3_tx. See LP skill 'Increase Task 3'.",
  "TASK 4 — Verify the result and report to the user. See LP skill 'Task 5' (same as create)."
]}

Increase Task 1: Prepare

Same as Create Task 1, but also ask the user for their position tokenId (they can find it on the Uniswap UI or from their wallet).

Increase Task 3: Build + Execute

Convert amounts to raw units, then call the API:

{
  "tool": "web_fetch",
  "url": "https://trade-api.gateway.uniswap.org/v1/lp/increase",
  "method": "POST",
  "headers": {"x-api-key": "$UNISWAP_API_KEY"},
  "body": {
    "protocol": "V4",
    "tokenId": "<token_id>",
    "walletAddress": "<wallet_address>",
    "chainId": 8453,
    "position": {
      "pool": {
        "token0": "0x4200000000000000000000000000000000000006",
        "token1": "0x587Cd533F418825521f3A1daa7CCd1E7339A1B07",
        "fee": 10000,
        "tickSpacing": 200,
        "hooks": "0x0000000000000000000000000000000000000000"
      },
      "tickLower": "<tick_lower>",
      "tickUpper": "<tick_upper>"
    },
    "amount0": "<raw_amount0>",
    "amount1": "<raw_amount1>",
    "poolLiquidity": "<from_task1>",
    "currentTick": "<from_task1>",
    "sqrtRatioX96": "<from_task1>",
    "slippageTolerance": 50
  },
  "extract_mode": "raw",
  "cache_as": "uni_lp_tx",
  "json_path": "increase"
}

Then decode and execute (same as Create Task 4):

{"tool": "decode_calldata", "abi": "uniswap_v4_position_manager", "calldata_register": "uni_lp_tx", "cache_as": "uni_lp"}

{"tool": "web3_preset_function_call", "preset": "uni_v4_modify_liquidities", "network": "base"}

{"tool": "broadcast_web3_tx", "uuid": "<uuid>"}

Operation D: Decrease Position (Withdraw) — 4 Tasks

Define tasks

{"tool": "define_tasks", "tasks": [
  "TASK 1 — Prepare: select Base, get tokenId and withdrawal percentage from user, read pool state. See LP skill 'Decrease Task 1'.",
  "TASK 2 — Build + Execute: POST to /lp/decrease, decode, execute, then broadcast_web3_tx. See LP skill 'Decrease Task 2'.",
  "TASK 3 — Verify the result and report to the user. See LP skill 'Task 5'.",
  "TASK 4 — Report: report withdrawn amounts. See LP skill 'Decrease Task 4'."
]}

Decrease Task 1: Prepare

Error Handling

V1 Limitations

• WETH only — not native ETH. Wrap ETH first using the weth_deposit preset.
• Manual tokenId — user must provide their position tokenId for increase/decrease/claim operations (findable on Uniswap UI or from wallet).
• Single pool — STARKBOT/WETH only initially. Extensible by adding to config/uniswap_pools.ron.
• No position enumeration — cannot list all positions automatically yet.

How Uniswap V4 LP Works

1. Create: Deposit token0 and token1 into a price range. You receive a position NFT (tokenId).
2. Earn fees: When swaps happen through your price range, you earn proportional fees.
3. Increase: Add more liquidity to your existing position.
4. Decrease: Remove some or all liquidity. Receive tokens back.
5. Collect fees: Claim accumulated trading fees without changing your position.

Key concepts:

• Tick range: Defines the price range where your liquidity is active. Narrower = more capital efficient but more impermanent loss risk.
• Concentrated liquidity: Unlike V2, your capital only works within your chosen range.
• Full range (tickLower=-887200, tickUpper=887200): Mimics V2 behavior, always active, less efficient.
