Wallet UX & payment engineering
We design and build wallet and payment systems that hide unnecessary blockchain complexity while keeping security, settlement, reconciliation, and operations explicit.
What we build
Account experiences integrated into your product, with passkey authentication, recovery policies, session controls, and custody boundaries selected deliberately.
Account abstraction, batching, paymasters, and sponsorship policies that remove gas friction without creating uncontrolled operational cost.
Collection, payout, settlement, ledger, webhook, and reconciliation flows designed for the chains, assets, and markets your business actually needs.
Reference architecture
A production wallet is not a login component, and an onchain asset transfer is not a complete payment system. We define every responsibility around the transaction.
Passkeys, device binding, authentication, recovery journeys, transaction intent, and clear user confirmation.
Smart accounts, permissions, spending limits, session keys, custody model, and approval rules.
Bundling, gas sponsorship, relaying, chain access, transaction simulation, retries, and finality handling.
Digital asset movement, ledger entries, reconciliation, webhooks, monitoring, support tooling, and accounting exports.
Controls across the flow
Architecture decisions
We define who can authorize value movement, how access is recovered, and what happens when a device, signer, or provider fails.
We compare settlement time, liquidity, fees, ecosystem support, operational tooling, and counterparty dependencies—not chain popularity alone.
Eligibility, budgets, rate limits, abuse controls, and fallback behavior keep gasless UX commercially sustainable.
Onchain state, application state, payment status, refunds, and accounting records need an explicit source-of-truth model.
Delivery
Map users, assets, jurisdictions, trust boundaries, failure cases, providers, and the operational owner of each step.
Implement one real journey across wallet, application backend, blockchain, and payment operations before expanding scope.
Add security controls, simulations, monitoring, reconciliation, cost limits, deployment, runbooks, and team handover.
Tell us who pays whom, which markets are involved, what the user should experience, and what can go wrong. We will help determine the right account, settlement, and operating model.
Useful context: payment flow, markets, assets, custody preference, timeline, and expected volume.
