I read different posts about smart contracts. I also checked most wallets, so far I don't find an easy service to setup
a) a recurring payment (monthly e.g.) or
b) a escrow service (to secure the xlm amount in an account, while the buyer is waiting for the product to arrive)
I'm not talking about the technical realisation (several tutorials exist already), I'm looking for an free to use webservice for anyone. Does it exist? Should somebody implement it?
