Every engagement runs under the same bar: specified before it is built, tested beyond the happy path, and documented well enough that your team can own it after handover.
- ✓Threat-modelled contracts. Access scoping, oracle guards and upgrade paths reviewed before code is frozen.
- ✓Invariant testing in Foundry. Property and fuzz coverage plus gas reports on every release candidate.
- ✓Reorg-aware data. Indexers with explicit cursors, backfill plans and websocket honesty during reorgs.
- ✓Device-lab wallet QA. Extensions, mobile deep links, in-app browsers and hardware wallets.

Delivery
From protocol architecture to mainnet
One active stage at a time. Select a stage to see timeframe, description and deliverables.

- API and event contracts
Exit criteria
Signed-off spec with performance budgets and test plan.
02 — Contract Sprints
Solidity built in weekly slices with Foundry invariant tests, gas reports and internal review on every merge.
Deliverables
- Contract system + tests
- Gas and coverage reports
- NatSpec documentation
Exit criteria
All invariants green; review notes closed.
03 — dApp & Wallet Build
React frontend with Wagmi and Viem, WalletConnect plus embedded wallets, simulation previews and explicit failure states.
Deliverables
- dApp frontend
- Wallet connection matrix
- Transaction-state coverage
Exit criteria
Device-lab QA pass on desktop and mobile.
04 — Indexing & Integration
Subgraphs, decoded event tables, realtime feeds and webhook reconciliation into your backend and ledger.
Deliverables
- Indexer + realtime API
- Webhook reconciliation layer
- Backfill and reorg report
Exit criteria
Sub-second reads; zero missed webhooks in soak.
05 — Audit Prep & Mainnet
Audit-prep pack, third-party audit support, fix verification, guarded rollout with caps, then full open and handover.
Deliverables
- Audit-prep pack
- Deployment ceremony scripts
- Runbook + knowledge transfer
Exit criteria
Findings remediated; runbook accepted by your team.

Audit-firstSecurity philosophy
We are engineers, not promoters. No token, no hype desk — just contract systems, dApps and data pipelines with tests, docs and runbooks. Our security philosophy is simple: assume hostile mainnet, prove safety with invariants, and let independent auditors verify.

FAQ
Questions, answered precisely
Ethereum, Polygon, Base, Arbitrum, Optimism and Solana. We help you pick a primary deployment network during architecture mapping, then abstract chain differences so expanding later does not mean rewriting.
Architecture, Solidity implementation, Foundry unit plus invariant tests, gas reports, NatSpec documentation and an audit-prep pack with threat model and deployment scripts.
Yes. We prepare systems for independent audit, join the review calls, remediate findings and produce fix-verification evidence. We do not mark our own homework — a separate firm always gives the final opinion.
WalletConnect for 300+ wallets, Privy embedded wallets for newcomers, SIWE sessions, simulation previews and a device-lab QA matrix covering extensions, mobile deep links and hardware wallets.
Yes. One codebase with a deployment registry, chain-specific QA for finality and fee behaviour, and unified indexing so portfolios and histories stay consistent across networks.
Swaps, staking, lending and vault frontends with oracle-backed pricing, slippage and deadline guards, permit flows and position tracking — paired with contract systems built for exact accounting.
Subgraphs and indexers over The Graph, Moralis, Alchemy and QuickNode with decoded schemas, backfill plans, reorg-aware cursors and websocket feeds — typically sub-second for product queries.
