What happens behind the scenes
1. Secure connection via Plaid
When you connect your brokerage, Tendrill uses Plaid - the same secure infrastructure used by Venmo, Coinbase, and thousands of financial apps. Here’s what happens:- You authenticate directly with your brokerage (Tendrill never sees your password)
- Plaid establishes a read-only connection to your account
- Only your holdings and positions are shared - we can’t move money or make trades
Read-only access only. Tendrill can see your holdings but cannot execute trades, transfer funds, or modify your account in any way.
2. Portfolio model creation
