Single-Sided LP Entry Tool

WHAT IT DOES

Single-Sided LP Entry Tool lets you add liquidity to a pool using only a single token—the other token is automatically swapped from your input token in the same transaction, creating a balanced LP position. Instead of manually acquiring both tokens, approving both, and adding liquidity in separate steps, you provide one token, specify the pool and tick range, and execute a single batched transaction. The tool checks your input token balance, verifies pool details, then swaps a portion of your input token for the other token and adds liquidity to the pool in one operation. This is essential for LPs who want to enter positions quickly without managing multiple token balances.

HOW TO USE

Connect your EVM wallet and select the network. Enter the pool address (e.g., Uniswap V3 pool), the input token address, and the amount you want to use. Set the lower and upper tick values for your desired range, and set your slippage tolerance. Click "Check balance" to verify your input token balance—the tool displays your balance, the amount you plan to use, and whether it is sufficient. Review the details, then click "Add single-sided liquidity" to execute the transaction. The tool swaps a portion of your input token for the other token, then adds liquidity to the pool at the specified tick range.

TECHNICAL MECHANISM

The tool first checks the input token balance using balanceOf() and reads the token decimals and symbol. It then uses a single-sided entry router that supports the swap + add liquidity pattern. The router performs the following steps in a single batched transaction: (1) approves the router to spend the input token, (2) calculates the required ratio of the two tokens based on the current pool price, (3) swaps a portion of the input token for the other token using a DEX swap router (e.g., Uniswap V3 SwapRouter) with slippage protection, and (4) calls mint() on the NonfungiblePositionManager to add liquidity with the now-balanced token amounts. The tool uses receipt.effectiveGasPrice for accurate gas reporting and applies slippage protection to ensure the swap executes within the user's tolerance.

WHAT IT CANNOT SEE

This tool cannot add liquidity if the input token balance is insufficient—balance is verified before proceeding. It relies on the DEX contracts supporting the specific swap + add liquidity interface; pools that do not support single-sided entry or use non-standard LP tokens are not supported. The tool cannot guarantee that the resulting position will be profitable—it may result in impermanent loss or lower yields. It also cannot avoid slippage entirely; slippage protection is applied but cannot guarantee execution if market conditions move against the user.

PLEASE NOTE

Single-sided entry automatically swaps a portion of your input token, which may incur swap fees and slippage. Ensure the tick range is appropriate for your strategy. The entry router contract must be trusted; verify its security and audit status before use. This tool is for EVM chains only and does not support non-EVM networks.
