Bidirectional Token Swap on PancakeSwap
Automated bidirectional token swapping workflow that swaps from any token to another and back on PancakeSwap V3, with transaction signing and automatic amount extraction from transfer events
Who is this for?
This workflow is designed for DeFi users who want to automate bidirectional token swaps on PancakeSwap V3. It's ideal for users who need to swap tokens programmatically and want to execute a round-trip swap (swap from Token A to Token B, then swap back from Token B to Token A) with transaction verification.
What problem is this workflow solving? / Use case
Manual bidirectional token swapping requires multiple steps: checking balances, initiating swaps in both directions, signing transactions, and verifying results. This workflow automates:
- Checking token balances before swapping
- Building swap transactions on PancakeSwap V3
- Requesting user signature for transactions
- Decoding transaction events to extract actual swap amounts
- Executing reverse swaps with the received amounts
What this workflow does
- Gets the current balance of the fromToken for the configured wallet address
- Builds a swap transaction from fromToken to toToken on PancakeSwap V3 with configurable slippage tolerance
- Requests user signature for the forward swap transaction
- Decodes the transaction transfer events to extract the toToken amount received
- Builds a reverse swap transaction from toToken back to fromToken using the received amount
- Requests user signature for the reverse swap transaction
Setup
- Connect your wallet address in the config node
- Configure the fromToken and toToken addresses (supports any ERC20 tokens on BSC)
- Set optional parameters: slippageBps (default: 100 = 1%), fee (pool fee), and amountIn (if you want to specify a fixed amount instead of using the full balance)
- Ensure you have sufficient balance of the fromToken in your wallet
- The workflow will prompt you to sign transactions when swaps are initiated
- Swap amounts are automatically extracted from transaction events for the reverse swap
Nodes in Use
-
ChainKit - Get Token Balance: Reads ERC20 token balance for ownerAddress on chainType
-
LiquidityHub - Swap tokens: Swaps fromToken to toToken on PancakeSwap V3 over chainType using accountAddress and amountIn (optional slippageBps, fee, recipient, deadline)
-
ChainKit - Sign Transaction: Signs transactions using chainType, from, to, value, data, gas, gasPrice, and nonce extracted from swap transactions
-
ChainKit - Decode Transfer Event: Decodes ERC20 Transfer events from a transaction hash on chainType to extract actual swap amounts
-
Set - Get To Token Balance: Extracts the toToken amount from decoded transfer events using dynamic token address from config
