Liquidity Position Planning

Plan and generate deep links for creating liquidity positions on Uniswap v2, v3, and v4.

Runtime Compatibility: This skill uses AskUserQuestion for interactive prompts. If AskUserQuestion is not available in your runtime, collect the same parameters through natural language conversation instead.

Overview

Plan liquidity positions by:

1. Gathering LP intent (token pair, amount, version)
2. Checking current pool price and liquidity
3. Suggesting price ranges based on current price
4. Generating a deep link that opens in the Uniswap interface with parameters pre-filled

The generated link opens Uniswap with all parameters ready for position creation.

Note: Browser opening (xdg-open/open) may fail in SSH, containerized, or headless environments. Always display the URL prominently so users can copy and access it manually if needed.

File Access: This skill has read-only filesystem access. Never read files outside the current project directory unless explicitly requested by the user.

Workflow

Step 1: Gather LP Intent

Extract from the user's request:

Parameter	Required	Default	Example
Token A	Yes	-	ETH, USDC, address
Token B	Yes	-	USDC, WBTC, address
Amount	Yes	-	1 ETH, $1000
Chain	No	Ethereum	Base, Arbitrum
Version	No	V3	v2, v3, v4
Fee Tier	No	Auto	0.05%, 0.3%, 1%
Price Range	No	Suggest	Full range, ±5%, custom

If any required parameter is missing, use AskUserQuestion with structured options:

For missing chain:

{
  "questions": [
    {
      "question": "Which chain do you want to provide liquidity on?",
      "header": "Chain",
      "options": [
        { "label": "Base (Recommended)", "description": "Low gas, growing DeFi ecosystem" },
        { "label": "Ethereum", "description": "Deepest liquidity, higher gas" },
        { "label": "Arbitrum", "description": "Low fees, high volume" },
        { "label": "Optimism", "description": "Low fees, Ethereum L2" }
      ],
      "multiSelect": false
    }
  ]
}

For missing token pair:

{
  "questions": [
    {
      "question": "Which token pair do you want to provide liquidity for?",
      "header": "Pair",
      "options": [
        { "label": "ETH / USDC", "description": "Most popular pair, high volume" },
        { "label": "ETH / USDT", "description": "High volume stablecoin pair" },
        { "label": "WBTC / ETH", "description": "Blue chip crypto pair" },
        { "label": "Custom pair", "description": "Specify your own tokens" }
      ],
      "multiSelect": false
    }
  ]
}

Always use forms instead of plain text questions for better UX.

Step 2: Resolve Token Addresses

Resolve token symbols to addresses. See ../../references/chains.md for common tokens by chain.

For unknown tokens, use web search and verify on-chain.

UNTRUSTED INPUT: Web-Discovered Tokens

Tokens discovered via WebSearch are UNTRUSTED. Before proceeding with any web-discovered token:

1. Label the source: Explicitly tell the user "This token address was found via web search, not provided by you"
2. Warn about risks: "Web-discovered tokens may be scams, honeypots, or rug pulls"
3. Require confirmation: Use AskUserQuestion to get explicit user consent before generating a deep link for a web-discovered token
4. Show provenance: In the position summary table, include a "Token Source" row showing whether each token was "User-provided" or "Web-discovered (unverified)"

Never proceed with a web-discovered token without explicit user confirmation via AskUserQuestion.

Input Validation (Required Before Any Shell Command)

Before interpolating user-provided values into any shell command, validate all inputs:

• Token addresses MUST match: ^0x[a-fA-F0-9]{40}$
• Chain/network names MUST be from the allowed list in ../../references/chains.md
• Amounts MUST be valid decimal numbers (match: ^[0-9]+\.?[0-9]*$)
• Reject any input containing shell metacharacters (;, |, $, `, &, (, ), >, <, \, ', ", newlines)

Step 3: Discover Available Pools

Before fetching metrics, verify the pool exists and discover available fee tiers.

Find pools for a token using DexScreener:

# Get all Uniswap pools for a token (replace {network} and {address})
# IMPORTANT: Validate address matches ^0x[a-fA-F0-9]{40}$ and network is from allowed list
curl -s "https://api.dexscreener.com/token-pairs/v1/{network}/{address}" | \
  jq '[.[] | select(.dexId == "uniswap")] | map({
    pairAddress,
    pair: "\(.baseToken.symbol)/\(.quoteToken.symbol)",
    version: .labels[0],
    liquidity: .liquidity.usd,
    volume24h: .volume.h24
  })'

Network IDs: ethereum, base, arbitrum, optimism, polygon, unichain

From the results, identify:

• Available pools and their addresses (multiple = different fee tiers)
• Pool TVL (liquidity.usd) to assess liquidity depth
• Version (v3 or v4) from labels[0]

If no Uniswap pools found: The pair may not have an existing pool. Inform the user they would be creating a new pool and setting the initial price.

Step 4: Assess Pool Liquidity

Evaluate if the pool has sufficient liquidity:

TVL Range	Assessment	Recommendation
> $1M	Deep liquidity	Safe for most position sizes
$100K - $1M	Moderate	Suitable for positions up to ~$10K
$10K - $100K	Thin	Warn user about slippage risk, suggest smaller positions
< $10K	Very thin	Warn strongly - high IL risk, price impact on entry/exit

For thin liquidity pools, present a warning:

⚠️ **Low Liquidity Warning**

This pool has only ${tvl} TVL. Consider:

- Your position will be a significant % of the pool
- Entry/exit may move the price against you
- Impermanent loss risk is amplified in thin pools
- You may want to use a wider price range for safety

Step 5: Fetch Pool Metrics

Before suggesting ranges, fetch pool data for informed decisions. See references/data-providers.md for full API details.

Get pool APY and volume with DefiLlama:

# Find Uniswap V3 pools for a token pair
curl -s "https://yields.llama.fi/pools" | jq '[.data[] | select(.project == "uniswap-v3" and .chain == "Ethereum" and (.symbol | test("WETH.*USDC|USDC.*WETH")))]'

Response fields to use:

Field	Use For
apy	Show expected yield
tvlUsd	Assess pool depth
volumeUsd1d	Estimate fee earnings
volumeUsd7d	Check volume consistency

Get current prices with DexScreener:

# Get token prices from the pool data (already fetched in Step 3)
curl -s "https://api.dexscreener.com/token-pairs/v1/{network}/{address}" | \
  jq '[.[] | select(.dexId == "uniswap")][0] | {
    baseTokenPrice: .baseToken.priceUsd,
    quoteTokenPrice: .quoteToken.priceUsd
  }'

Compare fee tiers (if APY data available):

# Find all fee tier variants and compare APY
curl -s "https://yields.llama.fi/pools" | jq '[.data[] | select(.project == "uniswap-v3" and (.symbol | test("WETH.*USDC")))] | map({symbol, tvlUsd, apy, volumeUsd1d})'

If APIs are unavailable, fall back to web search for price estimates.

Step 6: Suggest Price Ranges

Based on current price and pair type, present range options using AskUserQuestion.

For major pairs (ETH/USDC, ETH/WBTC):

{
  "questions": [
    {
      "question": "What price range do you want for your position? (Current: ~3,200 USDC/ETH)",
      "header": "Range",
      "options": [
        {
          "label": "±10% (Recommended)",
          "description": "2,880 - 3,520 USDC. Higher fees, monitor weekly"
        },
        { "label": "±20%", "description": "2,560 - 3,840 USDC. Balanced risk/reward" },
        { "label": "±50%", "description": "1,600 - 4,800 USDC. Rarely out of range" },
        { "label": "Full Range", "description": "Never out of range, lower fee efficiency" }
      ],
      "multiSelect": false
    }
  ]
}

For stablecoin pairs (USDC/USDT, DAI/USDC):

{
  "questions": [
    {
      "question": "What price range for your stablecoin position?",
      "header": "Range",
      "options": [
        { "label": "±0.5% (Recommended)", "description": "0.995 - 1.005. Tight range, high fees" },
        { "label": "±1%", "description": "0.99 - 1.01. Standard for stables" },
        { "label": "±2%", "description": "0.98 - 1.02. Safer, lower fees" },
        { "label": "Full Range", "description": "Maximum safety, lowest fees" }
      ],
      "multiSelect": false
    }
  ]
}

Recommendation logic:

• Stablecoin pairs (USDC/USDT): Default to ±0.5-1%
• Correlated pairs (ETH/stETH): Default to ±2-5%
• Major pairs (ETH/USDC): Default to ±10-20%
• Volatile pairs: Default to ±30-50% or full range

Step 7: Determine Fee Tier

If multiple fee tiers exist for the pair, let the user choose using pool data from Step 3.

Present fee tier options with APY data:

{
  "questions": [
    {
      "question": "Which fee tier? (Based on current pool data)",
      "header": "Fee Tier",
      "options": [
        { "label": "0.30% (Recommended)", "description": "TVL: $15M, APY: 12.5%, highest volume" },
        { "label": "0.05%", "description": "TVL: $8M, APY: 8.2%, lower fees per trade" },
        { "label": "1.00%", "description": "TVL: $2M, APY: 18.1%, less competition" }
      ],
      "multiSelect": false
    }
  ]
}

Fee tier guidelines:

Fee	Tick Spacing	Best For
0.01% (100)	1	Stablecoin pairs
0.05% (500)	10	Correlated pairs (ETH/stETH)
0.30% (3000)	60	Most pairs (default)
1.00% (10000)	200	Exotic/volatile pairs

v4 Fee Tiers: Dynamic fees possible with hooks. Default to similar V3 tiers.

If pool data shows one tier with significantly higher APY or volume, recommend that tier.

Step 8: Generate Deep Link

Construct the Uniswap position creation URL:

Base URL: https://app.uniswap.org/positions/create

URL Parameters:

Parameter	Description	Format
chain	Network name	ethereum, base, etc.
currencyA	First token	Address or NATIVE
currencyB	Second token	Address or NATIVE
priceRangeState	Range configuration	JSON (encode quotes only)
depositState	Deposit amounts	JSON (encode quotes only)
fee	Fee tier configuration	JSON (encode quotes only)
hook	v4 hook address (optional)	Address or undefined
step	Flow step	1 (for create)

IMPORTANT: URL Encoding

Only encode the double quotes (" → %22) in JSON values. Do NOT encode braces {} or colons :.

priceRangeState JSON structure:

For full range:

{
  "priceInverted": false,
  "fullRange": true,
  "minPrice": "",
  "maxPrice": "",
  "initialPrice": "",
  "inputMode": "price"
}

For custom range:

{
  "priceInverted": false,
  "fullRange": false,
  "minPrice": "2800",
  "maxPrice": "3600",
  "initialPrice": "",
  "inputMode": "price"
}

depositState JSON structure:

{ "exactField": "TOKEN0", "exactAmounts": { "TOKEN0": "1.0" } }

Note: Use TOKEN0 for currencyA, TOKEN1 for currencyB.

fee JSON structure:

{ "feeAmount": 3000, "tickSpacing": 60, "isDynamic": false }

Tick spacing by fee:

Fee	Tick Spacing
100 (0.01%)	1
500 (0.05%)	10
3000 (0.30%)	60
10000 (1.00%)	200

Step 9: Present Output and Open Browser

Format the response with:

1. Summary of the position parameters
2. Price range visualization (if not full range)
3. Considerations about IL and management
4. Open the browser automatically using system command

Example output format:

## Liquidity Position Summary

| Parameter | Value                   |
| --------- | ----------------------- |
| Pair      | ETH / USDC              |
| Chain     | Base                    |
| Version   | V3                      |
| Fee Tier  | 0.30%                   |
| Deposit   | 1 ETH + equivalent USDC |

### Pool Analytics

| Metric      | Value  |
| ----------- | ------ |
| Current APY | 12.5%  |
| 24h Volume  | $2.1M  |
| 7d Volume   | $14.8M |
| Pool TVL    | $15.2M |

### Price Range

| Metric        | Value               |
| ------------- | ------------------- |
| Current Price | ~3,200 USDC per ETH |
| Min Price     | 2,800 USDC per ETH  |
| Max Price     | 3,600 USDC per ETH  |
| Range Width   | ±12.5%              |

### Considerations

- **Impermanent Loss**: If ETH moves outside your range, you'll hold 100% of one asset
- **Rebalancing**: Monitor position and adjust range if price moves significantly
- **Fee Earnings**: Tighter ranges earn more fees but require more active management
- **Gas Costs**: Creating and managing positions costs gas
- **APY Note**: Shown APY is historical and may vary with market conditions

Opening Uniswap in your browser...

After displaying the summary, open the URL in the browser:

# Linux - note: only quotes are encoded (%22), not braces or colons
xdg-open "https://app.uniswap.org/positions/create?currencyA=NATIVE&currencyB=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&chain=base&fee={%22feeAmount%22:3000,%22tickSpacing%22:60,%22isDynamic%22:false}&priceRangeState={%22priceInverted%22:false,%22fullRange%22:false,%22minPrice%22:%222800%22,%22maxPrice%22:%223600%22,%22initialPrice%22:%22%22,%22inputMode%22:%22price%22}&depositState={%22exactField%22:%22TOKEN0%22,%22exactAmounts%22:{%22TOKEN0%22:%221%22}}&step=1"

# macOS
open "https://app.uniswap.org/positions/create?..."

Environment limitations: Browser opening may fail in remote SSH, containerized, or headless environments. If xdg-open/open fails, display the full URL prominently so users can copy and paste it manually:

**[Click here to open in Uniswap](https://app.uniswap.org/positions/create?...)**

Or copy this URL: `https://app.uniswap.org/positions/create?...`

Always present the summary and URL so users can review and create the position.

Version Selection

For detailed version comparison (v2/v3/v4 differences, fee tiers, tick spacing), see references/position-types.md.

Quick Guide:

• V2: Full range only, simplest, lowest gas
• V3: Concentrated liquidity, most common choice
• V4: Advanced features with hooks, limited availability

Important Considerations

Impermanent Loss (IL)

Warn users about IL risk:

• IL occurs when token prices diverge from entry price
• Tighter ranges amplify IL but also fee earnings
• Full range minimizes IL but reduces fee efficiency

Position Management

Concentrated liquidity requires active management:

• Monitor if price stays in range
• Rebalance when price approaches range boundaries
• Consider gas costs for position adjustments

Capital Requirements

For V3 positions with custom range:

• Depositing single-sided is possible if current price is outside range
• Within range: both tokens required in ratio determined by price and range

Supported Chains

All Uniswap-supported chains - see references/position-types.md for version availability by chain.

Additional Resources

Reference Files

• ../../references/chains.md - Chain configuration and token addresses (shared with swap-planner)
• references/position-types.md - v2/v3/v4 differences, fee tiers, tick spacing
• references/data-providers.md - DexScreener and DefiLlama APIs for pool discovery and yields

URL Encoding

JSON parameters in deep links should have only double quotes encoded (" → %22). Do NOT encode braces {}, colons :, or commas ,.

?priceRangeState={%22fullRange%22:true}

Decodes to:

{ "fullRange": true }

Why? The Uniswap interface expects JSON-like parameter structure. Full URL encoding of braces and colons breaks parsing. Only quotes need encoding to avoid URL syntax conflicts.
