Quecko builds crypto wallets across every custody model — non-custodial, custodial, and MPC-based — engineered to be as secure as a hardware wallet and as simple to use as a mainstream banking app, without asking users to become their own security expert.
Every Web3 product, no matter how sophisticated its underlying protocol, is ultimately experienced through a wallet — and wallets remain the point where mainstream users most often abandon crypto entirely, confused by seed phrases, gas fees, and unfamiliar signing prompts. Account abstraction and MPC custody have matured to the point where a genuinely mainstream-friendly wallet experience is achievable without sacrificing self-custody principles, but building it correctly requires treating UX and cryptographic security as one unified design problem rather than two separate concerns handled by different teams. Wallets sit at the highest-stakes point of any Web3 product — a single key-management flaw means permanent, irreversible loss of user funds with no customer support line to call and no chargeback process available. Teams routinely underestimate how much of wallet engineering is UX and recovery design rather than pure cryptography: industry data consistently shows that seed phrase confusion, phishing via unclear signing prompts, and lost recovery phrases cause far more fund loss than actual smart contract hacks or cryptographic breaks. A technically perfect key-management scheme still fails if real users can't operate it correctly under everyday conditions.
Tools, frameworks, and protocols we use to build secure and scalable solutions.
Model Agnostic — We build all major custody models with equal depth and recommend based on your actual risk profile and user base, not our own default preference or what we happen to have built most recently.

First Security — Recovery and signing flows are designed around how real users actually behave under everyday conditions, since most fund loss comes from confusion and forgotten backups, not sophisticated hacks.
Deep, current experience with ERC-4337 smart accounts for gasless transactions, social recovery, and programmable spending controls.
Wallet SDKs built to drop into any existing app without requiring a full standalone wallet product, meaningfully reducing your time to market.
