I believe this referring to Monzo linking with Chip on marketplace? And helping people save with automatic savings using transaction data .
With the potential to earn 5% bonus p.a. on your savings by recommending friends.
This is good as it has instant access to you funds
This will be for both Monzo & Starling using who have previously long been able to use this.
Little plug here my referral code is: 3RIIZI
