Mycelium Local Trader is a decentralized in-person exchange that is built right into your bitcoin wallet. Because the coins are stored locally in your wallet, the Local Trader exchange never needs to hold any of your bitcoins or fiat. Local Trader servers only help arrange the trade between buyers and sellers, manage the transaction, and calculate reputation ratings based on the trades.


All chat conversations are end-to-end encrypted using your bitcoin keys, and their context is only accessible to the people involved in the chat. The only things Mycelium servers receive is encrypted text with time stamps.


Mycelium Local Trader uses your bitcoin private key for registration and authentication with Mycelium servers. The only information retained by Mycelium servers is your bitcoin address, nickname, sell orders with the entered location, and your trade history.


The buyer’s and seller’s reputation is changed automatically based on the number of successful or aborted trades.
