A variable is an important concept in workflow. It allows you to store the result of a Processor after execution, enabling subsequent Processors to access results from previous ones. Variables also store Profile attributes, such as default variables like WALLET_ADDRESS, WALLET_PRIVATE_KEY, WALLET_PHRASE, and more. Variables make Processors more flexible, allowing them to perform tasks based on specific inputs.

How to use variables

Variable names must be written in uppercase, without spaces, and should not contain special characters. To use a variable in a Processor, enclose its name in curly braces { and }.
Example of variable WALLET_ADDRESS which stores address of the wallet

Example of variable WALLET_ADDRESS which stores address of the wallet

For example, if you have 1000 Profiles, each containing an EVM wallet, and the workflow runs 10 threads, each thread will operate on a different Profile. All Profiles include variables such as WALLET_ADDRESS, WALLET_PRIVATE_KEY, and WALLET_PHRASE, but their values will differ for each Profile. These variables store the wallet address, private key, and seed phrase, respectively.

Variable as Processor result

For Processors that need to store returned results, you can save these results in a variable specified in the Variable to save result field.
Example of storing the result from the Balance retrieval Processor

Note: It is recommended to use different variable names to store results for each Processor. If a subsequent Processor uses the same variable name as a previous one, the value will be overwritten by the latest Processor.
Subsequent Processors can use the results of previous Processors through variables.
Select the variable for the Uniswap swap Processor

Select the variable for the Uniswap swap Processor

In this example, the Uniswap swap Processor will use the wallet’s token balance from the WALLET_BALANCE variable, which is the result of the Balance retrieval Processor. You don’t need to enter the variable manually, just hover over the Select variable section and choose the variable you want to use.
