Swap smart contracts, also known as liquidity pool contracts, are the backbone of decentralized exchanges (DEXs) like Uniswap. These contracts facilitate token swaps and pool liquidity, allowing users to monitor and act on swap events in real time. By leveraging Swap Smart Contract Triggers, users can automate workflows and gain actionable insights, such as tracking swaps, filtering specific data points, or monitoring liquidity.

How to Set Up a Swap Smart Contract Trigger

  2. Configure the Trigger in K3

    1. Trigger Type: Smart Contract: Event

    2. Blockchain: Ethereum Mainnet

    3. Contract Address: Paste the liquidity pool contract address for the WBTC/USDT pair.

    4. Event Type: Select Swap from the dropdown menu. This ensures that the workflow triggers every time a swap occurs in the pool.

  3. Data Flow in Workflows: The trigger automatically captures data from every swap event and passes it to subsequent steps in your workflow. This includes token amounts, wallet addresses, transaction hashes, and liquidity details.

What You Can Do with Swap Data

Swap Smart Contract Triggers allow you to extract and utilize valuable data from liquidity pools. Here’s how you can use this data to enhance your operations:

  • Filter by Wallet Address: Track specific wallets participating in swaps. For instance, monitor high-value traders or track your own transactions to analyze trading strategies.

  • Analyze Token Amounts Swapped

    • Filter events based on the amount of WBTC or USDT swapped.

    • Automate alerts when a swap exceeds a predefined threshold (e.g., a swap larger than 10 WBTC).

  • Monitor Liquidity Size: Gain insights into liquidity pool changes. This is particularly useful for DeFi investors monitoring impermanent loss or liquidity withdrawal opportunities.

  • Custom Actions. Use the data to automate follow-up tasks, such as:

    • Rebalancing liquidity positions.

    • Executing arbitrage trades when swap thresholds are met.

    • Storing data in external databases for analytics or regulatory purposes.

Example Use Case: Tracking a High-Value Swap

Imagine you’re monitoring the WBTC/USDT pair on Uniswap. You want to be notified whenever a swap involves more than 50 WBTC. Here’s how this workflow might look:

  1. Trigger: A swap event occurs on the WBTC/USDT pair.

  2. Filter: Use an IF function to check if the amount of WBTC swapped exceeds 50.

  3. Action:

    1. Send an alert to your Telegram or email.

    2. Automatically execute a trade or liquidity adjustment in response.

    3. Record the transaction data in your database for future analysis.

Identify the Liquidity Pool Contract Address: To monitor swaps on a specific token pair, locate the liquidity pool contract address. For example, to monitor the WBTC/USDT pair on Ethereum, use tools like or Uniswap’s interface to find the pool’s contract address.
