|
This dApp demonstrates how to send and received end-to-end encrypted messages
|
|
|
|
|
using the encryption API provided by some Web3 Wallet provider such as [Metamask](https://metamask.io/).
|
|
|
|
|
|
|
|
|
|
The sender only needs to know the Ethereum address of the recipient.

|
The recipient must broadcast his encryption public key as a first step.
