How we ship
- 01
Discovery
We start with a structured workshop to map goals, users, constraints, and success metrics.
- 02
Design
Wireframes evolve into interactive prototypes you can test with real users before a line of production code is written.
- 03
Build
Weekly demoable increments, written tests, and code reviews — no surprises at launch.
- 04
Launch
Hardened deployments, observability, and a launch plan covering rollout, comms, and rollback.
- 05
Iterate
Post-launch we track usage, fix friction, and ship improvements on a cadence that fits your roadmap.
Engineered for outcomes, not invoices
- Ship a production wallet in 60–90 days, not 6 months
- Multi-chain from day one — no costly migration later
- Smart contract audit coordination included in delivery
- Full code and IP ownership on handoff
- Optional 24/7 on-call SRE post-launch
A modern, proven foundation
We pick boring, battle-tested tools so your platform stays maintainable five years from now.
Common questions
+What's the difference between custodial and MPC wallets?
Custodial holds keys on your infrastructure; MPC splits key material so no single party can sign alone — common for regulated retail products.
+Which blockchains do you support?
EVM L1/L2, Solana, and Bitcoin-family networks by default. Additional chains scoped per engagement.
+How is wallet security audited?
We run internal static analysis and fuzzing, then coordinate third-party audit before mainnet — findings remediated in the same sprint.
+Can we add fiat on/off ramp later?
Yes — we design wallet flows so PSP and KYC modules plug in without rewriting core signing.
+Do you provide the smart contract audit?
We deliver audit-ready code and manage the audit firm engagement; audit fees are quoted separately.
