DinDin is self-custody technology.

1. Operating model

DinDin lets users create or import wallets and sign transactions locally on their own devices. Digital assets remain under the control of the user's private keys, not DinDin.

DinDin's backend may store public addresses, wallet metadata, operational statuses, events and minimum data for support and integrations, but it has no ability to move assets without the user's action.

2. What DinDin is not

• we are not a bank, financial institution or payment institution;
• we are not an exchange, broker, custodian or buy/sell counterparty;
• we do not maintain fiat balances, payment accounts, internal order books or omnibus customer accounts;
• we do not provide investment advice, portfolio management, consulting or securities analysis;
• we do not promise returns, stability, redemption, liquidity or protection against losses.

3. Regulated partner services

When available, buy, sell, Pix/payment, KYC, AML, pricing, execution, settlement, refunds, limits, fees, blocks and regulatory reporting are handled by independent partners. Each partner is responsible for its own authorizations, regulatory obligations, terms and policies.

DinDin may act as a user-experience and technical orchestration layer, displaying partner information and transmitting minimum data needed for the flow you initiate. DinDin does not replace or control the partner's regulatory judgment.

4. Brazilian context

In Brazil, Law No. 14,478/2022 established guidelines for virtual asset service providers, and Decree No. 11,563/2023 assigned regulatory authority to the Central Bank of Brazil. Central Bank rules, including BCB Resolution No. 519/2025, address authorization and operation of virtual asset service providers.

DinDin structures its product as self-custody software and a technology layer. Partners that provide regulated services must evaluate and comply with authorizations and obligations applicable to their activities.

5. Digital asset risks

Digital assets may involve extreme volatility, total loss of value, low liquidity, protocol failures, attacks, scams, operational error, key loss, regulatory change, forks, congestion, high fees, smart contract failures and infrastructure outages.

Blockchain transactions can be irreversible. Sending assets to the wrong address, network or contract may cause permanent loss. You should verify addresses, networks, amounts, fees and risks before confirming any operation.

6. Tokens and securities

Some digital assets may be classified as securities, derivatives, financial instruments or regulated products in certain jurisdictions. Availability of an asset in the interface does not mean DinDin approval, recommendation or regulatory opinion.

7. Taxes and user obligations

You are responsible for evaluating tax obligations, filings, records, limits and restrictions applicable to digital asset use. Consult qualified professionals when needed.
