Blockchain development,
engineered to be audited
Smart contracts, DeFi, and tokenization built by senior engineers and shipped audit-grade — security reviewed, formally tested, and supported long after mainnet.
What we build on-chain
06 stepsEnd-to-end blockchain engineering — from a single audited contract to a full DeFi protocol or exchange. Senior teams, security-first defaults, and transparent delivery.
Smart contract development
Solidity smart contracts built to spec and gas-optimized — formally tested and security-reviewed before they ever touch mainnet.
DeFi development
Lending, staking, DEX, and yield protocols — economic design and contract engineering with security and audit-readiness from day one.
Tokenization & RWA
Tokenize real-world assets or launch a token platform — minting, custody patterns, and compliance-aware architecture end to end.
Smart contract audits
Independent security reviews — threat modeling, manual and automated analysis, and a clear findings report with prioritized fixes.
Crypto wallet development
Non-custodial and custodial crypto wallets — secure-enclave key storage, social recovery, and multi-chain assets, engineered to the security bar our Swissy wallet shipped with.
Crypto exchange development
Centralized and decentralized exchange platforms — matching engines, custody and settlement, KYC/AML, and trading UX, security-reviewed before a single trade clears.

Take your protocol from threat model to mainnet
Audited contracts, monitored deploys, and a team that has shipped on-chain for nine years.
Security is the
deliverable
06 principlesOn-chain code is adversarial by default — value is the attack surface. These principles keep what we ship from becoming a headline.
Audit-grade by default
Every contract is written to be audited — clear invariants, documented assumptions, and test coverage a third-party reviewer can verify.
Threat-model first
We map attackers, incentives, and failure modes before writing logic. Re-entrancy, oracle, and economic attacks are designed out, not patched in.
Test like value depends on it
Unit, fork, and invariant testing with fuzzing — because on mainnet a missed edge case is a withdrawal, not a bug ticket.
Minimize the trusted surface
Less on-chain code, fewer privileged roles, explicit upgrade paths. The smallest attack surface is the one we can actually reason about.
Independent review
Internal review, then external audit. We coordinate the audit, fix findings, and re-verify — the report is part of the deliverable.
Operate after mainnet
Monitoring, incident runbooks, and on-call support after launch — because shipping a contract is the start of its life, not the end.
From threat model
to mainnet
06 stepsOn-chain code is adversarial from block one. Our delivery loop is built around that — security is engineered in at every step, not bolted on before launch.
Threat model
Every engagement opens with a written threat model — attack surface, trust assumptions, and the assets at risk — agreed with you before any contract logic is scoped.
Spec & design
A design spec lands before code — documented invariants, state transitions, and a deliberately small trusted surface — so privilege and upgradeability are reviewed decisions, not defaults.
Build
Senior engineers write Solidity to spec — gas-optimized, readable, and structured so a third-party auditor can verify it.
Test & fuzz
The test suite ships as a deliverable — Foundry unit, mainnet-fork, and invariant tests with fuzzing — and the build is gated on coverage before it moves to review.
Audit
Internal review freezes the code, then we schedule and manage a third-party audit — triaging findings, shipping fixes, and booking a re-review so issues close before launch.
Operate
At launch we hand over monitoring dashboards, alerting thresholds, and incident runbooks, and stay on an on-call rota — so a live contract has owners, not just observers.
Every wallet model
we build
From self-custody to MPC and exchange-integrated — we build the wallet model your product and risk posture call for, secure by construction.
- NON-CUSTODIAL
Self-custody wallets
The user holds the keys — secure-enclave storage with seed or social recovery, the architecture behind our Swissy wallet.
Secure enclaveSocial recoverySeedless - CUSTODIAL
Custodial wallets
Provider-held keys with policy controls, approvals, and compliance hooks — for regulated products that own the custody risk.
Policy controlsApprovalsCompliance - MPC / MULTI-SIG
MPC & multi-sig wallets
Keys split across parties with threshold signing — no single point of compromise, for teams, treasuries, and institutional custody.
Threshold signingKey shardingTreasury - MULTI-CHAIN
Multi-chain wallets
One wallet across EVM chains and L2s — unified balances, in-app swaps, and bridging without juggling separate apps.
EVML2sSwaps & bridging - WEB3 / DAPP
Web3 & dApp wallets
In-app and browser-extension wallets — WalletConnect, dApp signing, and smart-account (ERC-4337) flows for gasless and social login.

Exchange & DeFi wallets
Wallets wired to trading, staking, and on-ramps — custody, settlement, and KYC/AML where the product needs it.

questions
07 questionsWhat founders and protocol teams ask before starting an on-chain engagement.
Core capabilities — smart contract development (Solidity, built to spec and gas-optimized), DeFi development (lending, staking, DEX, and yield protocols), tokenization and RWA platforms, crypto wallet and exchange development, and independent smart contract audits. Every engagement is senior-led and security-reviewed.
Yes. We run independent security reviews — threat modeling, manual and automated analysis, and a findings report with prioritized fixes — both on our own builds and on third-party contracts. For our builds we coordinate an external audit and re-verify after fixes.
We build primarily in Solidity on EVM chains (Ethereum, Polygon, Base, Arbitrum) and work with established Layer 2s. We choose the chain for security, cost, and ecosystem fit — not hype — and will tell you when going on-chain isn't the right call.
Yes. We cover economic design, smart contracts, and the application layer — wallets, dashboards, and indexing — so a DeFi protocol or Web3 product ships as a complete, usable product, not just contracts.
Yes. Tokenization and RWA work covers minting, custody patterns, and compliance-aware architecture — for fractional ownership, on-chain registries, and asset-backed tokens, designed for the regulatory posture your market requires.
On-chain code is adversarial by default, so we don't disappear at deploy. We provide monitoring, incident runbooks, and on-call support — because a contract's life starts at mainnet, not ends there.
Yes. We build non-custodial and custodial crypto wallets — secure-enclave key storage, social recovery, and multi-chain support — and centralized or decentralized exchange platforms with matching, custody, and KYC/AML. Our Swissy crypto wallet shipped to the App Store and Play with Swiss-grade security.
