What We Build

Embedded Wallet Onboarding

Create stablecoin wallets tied to email, passkey, or social login so payroll, treasury, and wallet products can get users active without seed-phrase friction.

Custody Model Design

Support non-custodial, MPC, or delegated custody setups based on your compliance model, support burden, and target geography.

Payout Orchestration

Build recurring payout, approval, and transfer flows for contractor payroll, treasury disbursements, marketplace settlements, and wallet-based collections.

Wallet UX & Transaction Flows

Deliver send, receive, balance, QR, address-book, and transaction-status experiences that make stablecoin movement legible to end users and ops teams.

Reconciliation & Ledger Views

Add balance snapshots, payout status tracking, and internal ledger views so finance and support teams can reconcile wallet activity without manual exports.

Fiat Rails & Funding

Connect on-ramp, off-ramp, bank-transfer, or card-funding flows so the wallet sits inside a complete money-movement journey instead of a crypto-only silo.

Compliance Hooks

Integrate KYC, KYB, sanctions screening, transaction monitoring, and jurisdiction-aware controls at the points where regulated wallet products need them.

Admin & Treasury Tooling

Equip internal teams with wallet monitoring, payout review queues, operational alerts, and treasury controls that keep stablecoin operations manageable at scale.

Multi-Chain Gas Strategy

Support chain selection, gas sponsorship, and fee abstraction so users can move stablecoins without learning the underlying chain mechanics first.

Compliance & Regulatory Note

Financial products involving payments, cards, accounts, stablecoins, or tokenized assets may require legal, regulatory, banking, issuing, custody, or compliance partners depending on the jurisdiction and product structure. We do not provide legal or regulatory advice. Our role is to design and build the software layer, integrate third-party providers, and implement the technical controls for onboarding, transaction monitoring, reporting, and risk management. You should work with qualified legal counsel and compliance partners to define and meet your regulatory obligations.

Frequently Asked Questions

Can you build a non-custodial stablecoin wallet?
Yes. We build wallets where the user controls their own keys, either via a seed phrase or a passkey-based MPC approach that removes the need for a seed phrase entirely. The right model depends on your target user and compliance requirements.
Can the wallet support account abstraction?
Yes. We build ERC-4337-compatible smart wallets with features like gas sponsorship, session keys, and programmable spending limits. This creates a much smoother UX for web3-native apps and fintech products.
Can users sign up with email or social login?
Yes. We integrate embedded wallet providers (such as Privy or Dynamic) that allow users to create a wallet using an email address or social account. The underlying key management happens in the background.
Can we add fiat on-ramp and off-ramp?
Yes. We integrate third-party on-ramp and off-ramp providers such as Transak, MoonPay, or similar. We build the frontend flow and backend integration; the fiat-to-crypto and crypto-to-fiat conversion is handled by the licensed provider.
Which stablecoins can the wallet support?
We commonly build support for USDC, USDT, and DAI. Multi-chain support means users can hold USDC on Ethereum, Base, Solana, and other chains within the same interface. The specific asset list depends on your product requirements.
Can this be built as a mobile app?
Yes. We build mobile wallets using React Native, which supports iOS and Android from a shared codebase. We can also build web-based wallets or Progressive Web Apps (PWAs) depending on your distribution strategy.
