SwapChat

SwapChat is a disposable, end-to-end encrypted, decentralized web app built on Ethereum Swarm Bee. It uses ephemeral identities generated on the fly and then it does a Diffie-Hellman key exchange to create a shared secret for reasonable security and privacy.

The project was initally done as a Swarm Hackweek Madrid 2019 project as a collaboration between @nolash from the Swarm team and @significance from Fair Data Society and @agazso from Felfele.

Building and running the app

First, install the dependencies:

 $ npm install

Then build the app:

 $ npm run pack-html-only

This builds the app in a single html file in the dist directory. You can upload it to Bee with the upload.sh command (curl is required):

 $ ./upload.sh http://localhost:8080

You can specify any Bee gateways as an argument. After the upload was successful the script will write out a link to the uploaded website. Copy that link to your browser to open it.

Development

For easier development configuration, set DEV_MODE = true at ./dist/index.html:15

Testing

To test the connection logic:

1. run ts-node ./src/index.ts in terminal 1, and while running...
2. look for tmp priv: <HASH> in the output, and copy the hash
3. run ts-node ./src/index.ts in terminal 2
