- * **Spend Mode**: Spend directly from yield-earning stablecoin vaults without borrowing.
- * **Virtual Visa Card**: Instant issuance of a virtual card accepted wherever Visa is accepted.
- * **Hooks DCA Feature**: Automatically dollar-cost averages into kHYPE with every card purchase.

Borrowing terms

Real-time USDC borrowing against collateral on Aave V3, Euler Prime (Base), and HypurrFi (HyperEVM)
Borrow mode: Traditional collateral-backed borrowing against Aave, Euler, or HypurrFi positions. Subject to collateralization ratios and liquidation risks. Spend mode: Direct spending from connected yield-earning stable vaults with no borrowing or liquidation risks.
Custody & risk
- If the issuer disappearsWhile the non-custodial model enhances security by keeping assets in user control, it relies on audited smart contracts. Users are still exposed to the inherent risks of the underlying DeFi protocols (e.g., Aave, Euler, HypurrFi), including smart contract vulnerabilities and liquidation risk in borrow mode.
- Market riskLiquidation risk when using volatile assets as collateral in borrow mode
- Market riskVariable borrow rates from underlying DeFi protocols
- Security riskNovel integration of DeFi protocols with payment systems may contain unforeseen risks
Swype.fun operates on a fully non-custodial model. Users retain their private keys and full control over their assets in their personal wallets. The platform uses smart contract delegation to borrow against collateral or spend from approved vaults, but it never takes direct custody of user funds.

What users say
Early social media feedback praises the instant borrowing and spending flow. One user described it as 'a DeFi protocol inside a card – insane.' Limited feedback due to recent launch and restricted access model.
