Advisory retainer
Ongoing office hours, design review, and prioritization support for leadership and tech leads — ideal when you want a steady senior sounding board without a full embedded team.
Web3 protocol consultancy
Engineering, security, and advisory for serious on-chain products.
We help protocols, funds, and product teams move from architecture through shipped code — with a security mindset across EVM and Solana, plus the integrations and operations layers around them.
How we work as a consultancy
ChainAdvisors operates as a specialized Web3 consultancy — similar in structure to how many boutique engineering LLCs and advisory shops support fintech and infrastructure: scoped statements of work, clear deliverables, and senior practitioners on the critical path.
Engagements range from short technical spikes (design review, threat modeling, test strategy) to multi-quarter build and hardening programs alongside your core team. We are comfortable partnering with in-house engineers, external auditors, and custody or infrastructure vendors so ownership stays transparent.
We provide technical consulting and implementation support; legal, tax, and regulatory interpretations remain with your qualified counsel.
Capabilities
A practical breadth of services across the lifecycle of a protocol or on-chain product — from first principles through scale and change management.
-
Protocol & systems architecture
Tokenomics-adjacent mechanics, upgrade paths, modular design, cross-chain considerations, and dependency mapping before code hardens assumptions.
-
Smart contracts & programs
Solidity and Solana (Anchor / Rust) for DeFi primitives, vaults, staking, routing, governance hooks, and asset issuance patterns.
-
Application & integration layer
APIs, indexers, wallets flows, admin tooling, and React / TypeScript frontends wired to on-chain state with observability and safe operational controls.
-
Security engineering
Invariant and property tests, fuzzing, formal-ish specifications where they pay off, and adversarial simulations aligned with how MEV and oracle markets actually behave.
-
Due diligence & vendor support
Technical DD for investors and acquirers, RFP support for auditors and infra providers, and readouts that translate chain risk into decision-ready language.
-
Reliability & operations
CI/CD patterns for contracts, deployment runbooks, incident playbooks, monitoring guidance, and post-launch tuning when parameters or markets shift.
Engagement models
We structure work the way modern consultancies and senior LLC practices typically do — so procurement, finance, and engineering leads all see the same expectations.
Fixed-scope build
Milestone-based delivery for a module, migration, or net-new feature set — with acceptance criteria, test artifacts, and handoff docs.
Security augmentation
Time-boxed hardening sprints ahead of audits or mainnet upgrades: test harness expansion, exploit rehearsal, and remediation pairing.
Due diligence sprint
Compressed technical review for investors or partners — codebase, architecture, and operational risks summarized in a structured memo.
Sectors & contexts
We have the deepest bench in DeFi and on-chain finance, but we also support adjacent contexts where asset safety and clear interfaces matter just as much.
Security is part of delivery
The goal is not a checkbox audit — it is to understand how a system fails before it meets adversarial conditions in the wild. We align test plans with realistic threat models and the economics of your market.
- Invariant and property-based testing
- Fuzzing and scenario simulation
- Exploit modeling (reentrancy, oracle paths, privilege edges)
- Review support for high-TVL and upgrade-sensitive deployments
- Coordination with third-party auditors and bug bounty programs
Technologies
Deep on-chain work, plus the surrounding stack for end-to-end delivery when the engagement requires it.
Chains
EVM (Solidity), Solana (Rust, Anchor), CPI and PDA-heavy flows
Application
TypeScript, Node.js, React, APIs and indexing patterns
Quality
Test harnesses, CI, deployment tooling, operational runbooks
Public resources we align with
We routinely reference ecosystem documentation and open security guidance — useful whether you are evaluating vendors or upskilling your team.
