Swype.fun | FAQs
Swype.fun is a DeFi-native credit card, powered by Brahma Cards, that lets you access credit against your crypto in real-time. Each time you swipe for a payment, Brahma Infrastructure automatically connects to lending protocols like Aave or Euler, borrows USDC against your onchain assets, and settles the transaction instantly. Now expanding to HyperEVM via HypurrFi In addition to Swype v1.0 on Base, Swype is now be accessible to top HypurrFi users on HyperEVM via a unique invite-code-based onboarding. This new access path is exclusive: users must rank high on HypurrFi’s leaderboard, complete KYC, and connect an EOA that holds an active position in HypurrFi.
Getting Started
On Base: hold at least $100 in collateral on a combination of Aave or Euler positions (on Base network). Alternatively, you can gain early access through limited-time invite codes by commenting on Brahma's Swype launch tweet.
On HyperEVM: available only to top HypurrFi users. You can check your eligibility here https://app.hypurr.fi/card
Note: Existing Base users will not be eligible to access Swype on HyperEVM automatically.
How do I connect my wallet to Swype?
Connect and link your existing wallet to Swype through the interface. You maintain full control of your assets at all times. Swype never takes custody of your funds. Your card is directly connected to your EOA (wallet address) - if you lose access to your wallet, you lose access to your card. We plan to support multiple wallets and social integrations in future versions, but V1.0 of Swype allows only for a single EOA wallet connection.
Note: You can only connect one EOA to your Swype Card and its KYC.
What is approval and why do I need to set it?
Approval grants Swype permission to borrow on your behalf through lending protocols. You control:
Protocol and collateral assets
Maximum borrow amount
Do I need to complete KYC?
Yes. You'll complete a one-time KYC process through SumSub to get your virtual card issued. We don't store your details - they're securely stored with SumSub for regulatory compliance. Please note in V1.0 your KYC is tied to your connected EOA when you start the KYC, so choose the wallet accordingly. At the moment it cannot be changed once you KYC. We plan to extend support for more accounts under your Swype profile soon.
What countries are restricted and can't use Swype?
The following countries are restricted for cardholder services: Cuba, Democratic People's Republic of Korea (DPRK), Egypt, Iran, Myanmar, Nigeria, Russia, South Africa, Syria, Ukraine, Venezuela
Restricted US States: Arizona, Delaware, Georgia, Idaho, Louisiana, Maryland, Missouri, Montana, Nevada, New Mexico, North Dakota, Ohio, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, Wisconsin, Wyoming
Note: Geographic restrictions are subject to change based on evolving regulatory requirements and risk assessments. BrahmaFi reserves the right to modify these restrictions as required by law or policy.
What chains are supported?
Swype currently supports Base chain only for both Aave and Euler integrations. Support for additional chains may be added in future versions.
What happens after I approve my card policies?
Only after you review and approve the card policies (protocol, collateral and amounts) will your virtual card be generated. The card is then linked to a dedicated subaccount within your Brahma account.
What happens if I lose wallet access?
Your card is linked to your connected wallet (EOA). If you lose access to your wallet, you also lose access to your card. Make sure to back up your private key and seed phrase securely.
How Swype Works
Which lending protocols does Swype support?
Currently Swype supports:
AAVE: Direct borrowing against your deposited collateral
Euler: Creates a subaccount for isolated risk management
HypurrFi on Hyperliquid (Now Live)
Swype now supports HypurrFi, a lending protocol on HyperEVM, exclusively accessible to top HypurrFi users. The same real-time credit experience will be extended to eligible users on HypurrFi, with all credit access routed through Brahma Infrastructure.
Note: You can only use one on the lending protocols for your Swype Card. In future versions we plan to allow for switching the chosen protocol.
Why do my assets move when I approve Euler?
When you approve an Euler position, a sub-account on Euler is created that you own. Swype only gets delegation rights to borrow on your behalf. This is documented in Euler's official documentation.
What happens when my credit limit is exhausted on AAVE?
Once the credit amount is exhausted, you need to reapprove as the system won't extend credit beyond the approval limit. This is a safety feature to prevent unauthorized borrowing.
How fast is the borrowing process?
When you swipe, Brahma Infrastructure instantly connects to the lending protocol, borrows USDC, and pays the merchant in real-time. The entire process happens within seconds.
Your Position
How do I repay or manage my loan?
Borrowed funds are held directly in your connected lending protocol (Aave or Euler) on your wallet. To repay, simply visit the protocol’s UI, connect your wallet, and repay the borrowed USDC.
You can also deposit additional collateral to reduce utilization or increase your available Swype limit.
What happens if my collateral value drops?
If your collateral value falls below safe thresholds, your position may be liquidated by the lending protocol (Aave, Euler or HypurrFi). Swype does not intervene. Your position is entirely self-custodial and managed by the lending protocol logic.
Make sure to monitor your health factor and collateral levels. You can reduce risk by topping up your collateral.
To add collateral:
Go to Swype → Borrow Mode → Add Collateral, select a supported asset, and sign the transaction to delegate it to Swype.
Do I generate yield on the collateral used for Swype?
Yes. Your assets continue to earn supply-side yield directly from the lending protocol while they serve as collateral for your Swype borrowing.
Can I repay my loan or add collateral from the Swype UI?
Not currently. All loan repayments and collateral management must be done through the lending protocol’s UI (Aave or Euler).
Simply connect the same wallet you use for Swype to the protocol and manage your position from there.
My Available Limit is low. How do I add more collateral tokens and amount to use with my Swype Card?
You can increase your Swype limit in two ways:
Top up an existing collateral token
→ Deposit more of the same token directly into the lending protocol. Then in Swype, go to Borrow Mode → Add Collateral, select the token again, and sign to update your delegated amount.
Add a new supported collateral token
→ Deposit a new supported token into the protocol using the same wallet. Then, visit Swype → Borrow Mode → Add Collateral, select the new token, and approve it for use with Swype by signing.
Card Management
How do I check my available spending amount?
Use the Swype interface to view your available transaction amount based on your underlying collateral and transaction history.
Can I have multiple cards?
Currently, you can only have one card per account.
Can I change my underlying protocol?
You will be able to change the underlying protocol and modify approvals in the coming weeks.
Security and Policies
How are my funds protected?
We never deposit your funds. The Brahma Infrastructure only takes approval on underlying DeFi protocols and has no withdrawal rights on your collateral. You maintain full custody of your assets at all times.
Can I set spending restrictions?
Currently, you can set daily spending limits and freeze your card. More advanced policy controls will be available in future updates.
What if I want to stop all card activity?
You can freeze your card or remove the approval entirely through the Swype interface.
