It's important to understand that wallets don't have custody of users' funds. Wallets are simply a tool for managing assets held on the blockchain in a specific address. This is called self-custody. Users are responsible for their assets, private keys, passwords and any other information they have used or provided to set up a wallet. Other than the data users are required to share for identification purposes, Swarm Markets will never request access to any other private information such as private keys or passwords.
