I've seen instant seal mentioned as a way to get transactions sealed by the substrate node upon receipt.

I also know that moonbeam have this in their node.

Is there a substrate node that includes pallet-contracts and also implements instant seal?

If not, is it possible to modify the substrate contracts node to include this?

The substrate contracts node already uses instant seal. Just update to the latest version.

  • Thanks, I guess the last time I used it was a while ago!

  • Is it a good idea to use instant seal for production? (for example, if I expect there are infrequent transactions in my custom solo chain)
