Mycelium is a non-custodial cryptocurrency wallet, which means users have full control over their private keys and funds. In a non-custodial setup, the wallet provider does not store or manage users’ assets; instead, all sensitive data, such as private keys and seed phrases, is stored locally on the user’s device. This gives users complete ownership and responsibility for their cryptocurrency, without relying on a third party for access or security.

Mycelium’s non-custodial design aligns with the core principle of decentralisation in the crypto space. Since the wallet never has access to users’ private keys, it cannot freeze, recover, or manipulate funds. This setup offers strong privacy and security, but it also means users must carefully back up their recovery phrase; if it’s lost, there’s no way to retrieve their assets.

The wallet also integrates with hardware devices like Trezor and Ledger, allowing users to manage funds securely while keeping private keys offline. Mycelium supports features such as Local Trader, which enables peer-to-peer Bitcoin trading directly between users without intermediaries.

In summary, Mycelium is a non-custodial Bitcoin wallet focused on privacy, user control, and direct blockchain interaction. It offers strong security and flexibility for experienced users, while emphasising personal responsibility for safeguarding private keys and backup phrases.
