Processor Swap Pancakeswap
This Processor enables token swaps from a Pancakeswap pool. The swap is executed via Pancakeswap's Universal Router contract—the same contract used when you swap tokens through the Pancakeswap interface.
Supported pool types for swapping:
Pancakeswap V2
Pancakeswap V3
Libraries used in the swap Processor code:
5.8.8
3.8.11
1.0.10
5.7.2
In the example above, the configuration swaps FLOKI tokens to BNB using the FLOKI/WBNB pool on the BNB network.
Configuration meanings:
Variable name for storing result
Yes
This Processor will output the transaction hash of the swap. You can choose a variable name to store the transaction hash. For example: TX_HASH_SWAP_TOKEN_EVM
Private key
Yes
This is the private key of the wallet performing the transaction. Each Profile has a default variable for storing the private key, so you can use the default variable WALLET_PRIVATE_KEY
Chain
Yes
The blockchain network where you want to perform the swap
Node endpoint group
Yes
Select the node provider to interact with the blockchain
Pool address
Yes
The address of the pool you want to swap in
Input token address
Yes
A pool contains two tokens. Here, you enter the address of the token you want to swap from. For example, if you want to swap FLOKI for WBNB (sell FLOKI), you should enter the address of the FLOKI token in this field
Output token address
Yes
The address of the token you want to receive after the swap. For example, if you want to swap FLOKI for WBNB (sell FLOKI), enter the address of the WBNB token here. If you prefer to receive the native token instead of WBNB, you can select Receive native token after swap (if the output token is a wrapped token). This option applies only to pools with wrapped tokens
Input token amount
Yes
Enter the amount of tokens you want to sell. For example, if you wish to sell 1,000 FLOKI for BNB, enter 1000
Slippage tolerance (%)
Yes
Maximum slippage for swaps. For pools with low price volatility, you should set this value low (e.g., 0.3%, 0.5%). For pools with high price volatility over short periods, set a higher value to increase the likelihood of a successful swap
Deadline (second)
Yes
Maximum time allowed to complete the swap transaction. For example, if you enter 10, the transaction will be canceled (reverted) if the swap is not completed within 10 seconds.
Max price impact (%)
Yes
Maximum price impact for swaps. For pools with high liquidity, you should set this value low (e.g., 0.5%, 1%). For pools with low liquidity, you may choose a higher value
Gas limit
No
Gas limit for executing the transaction
Gas price (Gwei)
No
Gas price for executing the transaction. If you do not specify a value, the gas price will default to the current average on the chain. For best results, it is recommended to set the gas price to increase the likelihood of a successful swap transaction
Total number of transaction
Yes
The minimum value is 1. If you enter a value greater than 1, such as 10, this Processor will broadcast 10 swap transactions simultaneously, each with a different nonce, to increase the likelihood that multiple transactions are mined in the same block
Wait for the transaction to be confirmed?
No
If you enable this option, the Processor will wait for the swap transaction to be confirmed before proceeding to the next Processor. If you leave it unchecked, the Processor will broadcast the swap transaction without waiting for confirmation and immediately move on to the next Processor
How to choose Gas Limit and Gas Price
If you want your transaction to be mined faster by competing on gas, or if the Processor cannot estimate the Gas Limit for certain transactions, you can manually enter the Gas Limit and Gas Price for the Processor.
For example, if you want to swap tokens in the FLOKI/WBNB pool, review several recent transactions to see their Gas Limit and Gas Price. This will help you select suitable values for the Processor.
Using the following transaction as a reference: https://bscscan.com/tx/0xf440fc6449d5363ea0e948b4956347a92023bc8ec3207230748a7d4e8a510509, you can set the Gas Price (Gwei) to 1 Gwei and the Gas limit to 235798 for the Processor.
