Where is my money stored and who controls it?

Traditional finance apps store your money in accounts they control and show you a balance in their system. COCA is built differently – you own your money.

Your money stays in the wallet you control

In COCA your 'Banking Account' is actually a blockchain smart wallet that you control. COCA provides the bank-like interface (app, card, support, compliance rails), but the funds are not under our control.

Think of it as:

• Bank app experience

• Cash-style ownership

What “smart wallet” means (without the crypto headache)?

COCA uses smart contract wallets (EIR-4437, EIP-7702) and this is what makes COCA feel like a normal bank:

• All your funds are stored on the blockchain and controlled by you

• You have safer sign-in and recovery flows without a seed phrase

• You set rules (limits, permissions, spending controls)

• The wallet approves actions in a user-friendly way without you doing “crypto steps” every time

It’s the tech that makes blockchain adoption possible.

How payments work with COCA card?

When you pay with the COCA card, the merchant requests an authorization (e.g., €42.70). COCA’s system is designed so that:

1. A card authorization happens (like any card)

2. Your smart contract wallet approves that specific amount for that specific payment

3. Only the authorized amount is moved for settlement – not your whole balance

So instead of “COCA can access everything”, it works like this:

Pay this merchant, this amount, right now – and nothing else.

You are also protected by:

• Daily/weekly spending limits

• Merchant or subscription permissions

• Instant freeze controls

This is how COCA creates a Self-Banking experience: it feels like a bank while treating your money like it belongs to you, not to COCA.
