Building Batched Streams in Safe
Send multiple streams in the same transaction with Safe transaction batching
If you have a Safe and are looking to send multiple streams in one transaction rather than having to manually execute each one, this guide will show you how it's done.
1. Go the Safe Transaction Builder
2. Get CFAv1Forwarder Address
Find the CFAv1Forwarder address for the desired network below:
Ethereum Mainnet Polygon Gnosis Chain Optimism Arbitrum Avalanche BNB Chain Goerli Arbitrum Goerli Optimism Goerli Mumbai
0xcfA132E353cB4E398080B9700609bb008eceB125
Avalanche Fuji
0x2CDd45c5182602a36d391F7F16DD9f8386C3bD8D
Paste that address in the Enter Address or ENS Name box on the Transaction Builder interface.
3. Copy CFAv1Forwarder ABI
Copy the ABI below and paste in the Enter ABI box in the Transaction Builder interface.
Expand for CFAv1Forwarder ABI
Hover over the code box below and click the copy icon on the top right.

]4. Line Up Streaming Transactions
Now you'll be able to set up each stream transaction for the batch one at a time.
If you're looking to create streams, select the createFlow method.
Function Parameters
token (address) - Super Token you're streaming
sender (address) - Your Safe address
receiver (address) - The receiver address
flowrate (int96) - Flow rate in seconds
Flow Rate is always in wei/second. Super Tokens always have 18 decimals of precision. For example: You want to stream 1000 DAIx/month to Alice
flowrate = 1,000 * (10^18) / ( seconds in month )
flowrate = 1,000 * (10^18) / ( (60 * 60 * 24 * 365) / 12 )
flowrate = 1,000 * (10^18) / 2628000
flowrate = 380517503805175
userData (bytes) - put in 0x
- - -
Hit Add Transaction and repeat for each stream you'd like to send 🔁
5. Create and Send the Batch
Once you added all operations to the batch click "Create Batch" and then "Send Batch". After execution, your streams should be running!
You can check out the Superfluid Safe App to see the streams in action and conduct necessary modifications.
