What We Build

Wallet Funding & Ledgering

Users fund their card balance by depositing stablecoins such as USDC or USDT, while the platform detects deposits, confirms settlement, and updates the spendable ledger in real time.

Settlement Orchestration

Move from crypto balances to card-ready fiat spending through off-ramp, treasury, and settlement partner workflows that match your operating model.

Issuer & Processor Integration

We integrate card issuing processors and BIN sponsors for virtual card provisioning, authorization handling, webhooks, spend controls, and settlement reporting.

Spend Controls

Configurable spending limits, merchant category restrictions, geographic blocks, and single-use card modes exposed in the user app and admin dashboard.

KYC / KYB

Identity verification and compliance screening before card issuance, integrated with your chosen onboarding, risk, and monitoring providers.

Transaction & Reconciliation History

A full event log across deposits, conversions, authorizations, settlements, reversals, and refunds that operations teams can search and export.

Risk Controls

Fraud detection rules, velocity limits, wallet screening, and unusual-activity flagging that complement your processor and compliance stack.

User App

A crypto-native card experience with wallet funding instructions, balance visibility, card controls, transaction history, and real-time alerts.

Program Operations Dashboard

Operational tooling for user and card management, KYC status, balance monitoring, exception handling, and partner settlement reconciliation.

Compliance & Regulatory Note

Crypto card programs sit at the intersection of virtual asset services and regulated payment card products. They typically require KYC/KYB for all cardholders, AML controls, and may require virtual asset service provider (VASP) registration, e-money licensing, or other regulated status depending on jurisdiction and product structure. We build the software platform and integrate the relevant providers; we do not provide banking, card issuing, or virtual asset conversion services directly.

Frequently Asked Questions

How does funding a crypto card work technically?
The user sends stablecoins (USDC or USDT) to an assigned deposit address. The platform detects the transfer on-chain, confirms it, and credits the user's spendable fiat balance through a conversion step. The card processor then allows spending against that balance. The exact conversion mechanism depends on the off-ramp or settlement partner you use.
Do you issue cards directly?
No. Card issuance requires a card issuing processor and BIN sponsor with Visa or Mastercard network participation. We build the platform and integrate the processor. Some processors offer program manager models that simplify entry for new programs.
Can the card be used anywhere Visa or Mastercard is accepted?
Yes, subject to your card program's geographic and MCC restrictions. The virtual card functions like any Visa or Mastercard virtual card once the user has a funded balance and an active card number.
Which stablecoins can be used to fund the card?
We commonly build support for USDC and USDT. Other assets such as ETH, BTC, or other stablecoins can be supported if there is a conversion path to the fiat balance. The final asset list depends on your product requirements and available liquidity partners.
What happens to the crypto during a card transaction?
The stablecoins are converted to a fiat spending balance when deposited (or just before authorization, depending on the architecture). Card authorizations draw down the fiat balance. The user's crypto is not held on-chain when a card purchase occurs.
What compliance is required for a crypto card platform?
KYC/KYB for all cardholders, AML screening, and transaction monitoring are standard requirements. Depending on jurisdiction, additional licensing for virtual asset services, e-money, or payment processing may apply. We build the compliance layer; you work with legal and compliance partners to define obligations.
