How we ship securely

Security is the
deliverable

On-chain code is adversarial by default — value is the attack surface. These principles keep what we ship from becoming a headline.

01 / PRINCIPLE

Audit-grade by default

Every contract is written to be audited — clear invariants, documented assumptions, and test coverage a third-party reviewer can verify.

02 / PRINCIPLE

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.

03 / PRINCIPLE

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.

04 / PRINCIPLE

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.

05 / PRINCIPLE

Independent review

Internal review, then external audit. We coordinate the audit, fix findings, and re-verify — the report is part of the deliverable.

06 / PRINCIPLE

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.

Delivery

From threat model
to mainnet

On-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.

01SCOPE

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.

attackers first
02DESIGN

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.

architecture · invariants
03DELIVERY

Build

Senior engineers write Solidity to spec — gas-optimized, readable, and structured so a third-party auditor can verify it.

solidity, gas-aware
04ASSURANCE

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.

unit · fork · invariant
05REVIEW

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.

internal + external
06OPERATIONS

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.

Blockchain development
questions

What 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.
