I downloaded cashu the other day both on android and iOS , then I delete it . I can’t remember why , .. oh now I remembered it . Something with Mint token It’s because ecash or Cashew is not decentralized network , E cash depends on central mint or federation issued the token, while lightning wallet is decentralized so no one control the bitcoin . Hmm , Lightning send actual Bitcoin over the network , while E cash just send tokens issued by the issuer . You really need to trust the issuer or else you get screwed .
