The flow of interacting with an Aepp
When a webpage is opened the extension is injecting an Aepp object in it.
In order for a webpage (assuming but not limited to decentralized application) wants to interact with the waellet extension it needs to perform 2 steps.
- First the page should ask the user for confirmation and authorization of the connection.
Example call for connection authorization:
Aepp.request.connect().then(res => console.log(res))
Result (promise):
{message: "Connection established"}
- The page can invoke a transaction signature request from the user like so:
Example call for transaction sign:
Aepp.request.sign({recipientId:"ak_2DDLbYBhHcuAzNg5Un853NRbUr8JVjZeMc6mTUpwmiVzA4ic6X", amount: 0.01}).then(res => console.log(res))
Result (promise) uppon confirmation:
