Is there a TypeScript library to automate buffering Cashu payments to/from a mint while allowing users to hold the majority of their sats on a second Lightning-enabled subnet (e.g. Liquid/Spark/Ark)?
So you mean a cashu wallet lib with an automatic exit to the subnet? I am currently working on a batteries-included cashu lib to streamline wallet dev. Adding a subnet would happen a layer above, but at least this would take care of all the cashu orchestration
