Supercool's relayer lets you programatically create transactions without worrying about nonce management, secret key storage, gas price estimation, transaction retries, and network error handling. Supercool handles all of those details for you.
You can use the relayer to:
- automate your contract interactions on a schedule or in response to events
- create gasless meta-transactions for your users
- chain together multiple transactions in a sequence or send 100s of transactions in parallel
- create transaction sessions for users so they can sign multiple transactions without being prompted by Metamask confirmations repeatedly
Check out the overview for more info about the relayer, or learn about gasless transactions and transaction sessions. You can also learn how Automation Engine can help you automate transaction creation using our plug-and-play modules to respond to on-chain or off-chain events and create transactions on a schedule.
