In æternity ecosystem, the app that has access to user's private keys and grants other apps access to them is called wallet. Respectively, the app that is granted access is called aepp.
This folder has been created to showcase the æternity SDK integration to both wallets and aepps.
If you are trying these examples after checking out this repo,
you want to first run npm install, from the repo root, to get all the SDK dependencies installed,
and only then, move to individual apps installations.
The Sample æpp project (Distributed App or dapp) shows how you can create a simple æternity æpp, dependent on a Wallet, in this case: offering the possibility to work with contracts.
The Wallet WebExtension example project shows how you can create a simple æternity wallet as a Chrome/Firefox browser extension. This approach is actively used in Superhero Wallet.
The wallet example project shows how you can create a simple æternity wallet that opens æpps in iframe. This approach is actively used in Base æpp.
