Frequently asked questions

Mailchain ensures privacy and security through several measures. Firstly, all messages sent through Mailchain are end-to-end encrypted using unique keys known only to the recipient. This ensures both forwards and backwards secrecy, as Mailchain cannot see a user's encrypted user profile or messages. The decryption process occurs on the client side, within the user's browser.

Additionally, Mailchain does not require knowledge of a user's private keys to send and receive messages from existing blockchain addresses. Instead, it utilizes a unique identity key, along with corresponding signing and encryption keys for each registered account. This means that Mailchain does not have access to the user's private keys, enhancing security.

Furthermore, Mailchain stores messages on decentralized storage, ensuring that they are encrypted and safeguarding user privacy. This decentralized approach prevents anyone from seeing which wallets are connected to a user's Mailchain account.

Overall, Mailchain aims to provide a secure, private, and decentralized communication platform that respects user privacy and offers robust security measures.

  1. Install the Mailchain SDK: Developers can install the Mailchain SDK in their project by running the command npm install @mailchain/sdk.

  2. Import the Mailchain module: Developers need to import the Mailchain module in their code using the following line: import { Mailchain } from '@mailchain/sdk';.

  3. Set up the Mailchain instance: Developers should create an instance of the Mailchain class by providing a secret recovery phrase. This can be done using the following code:

const secretRecoveryPhrase = process.env.SECRET_RECOVERY_PHRASE!;
const mailchain = Mailchain.fromSecretRecoveryPhrase(secretRecoveryPhrase);
  1. Send a mail: Developers can use the sendMail method of the Mailchain instance to send a mail. They need to provide the sender address, recipient addresses, subject line, and content (text and HTML). Here's an example:
const result = await mailchain.sendMail({
  from: `allofweb3.eth`, // sender address
  to: [`epistola.lens`], // list of recipients
  subject: 'Mailchain now supports .lens profiles 🌿', // subject line
  content: {
    text: 'Hello Frenz 👋', // plain text body
    html: '<p>Hello Frenz 👋</p>', // html body

By following these steps, developers can easily integrate Mailchain into their applications and enable web3-native email communication with their users.
