Overview
Threat modelling systematically identifies what can go wrong: assets at risk, adversaries and their capabilities, attack paths across contracts, keys, infrastructure, oracles and governance, and mitigations. We run threat modelling workshops and produce models that guide design decisions, testing priorities and audit scope.
Common use cases
- New protocol designThreat model before implementation.
- Audit scopingFocusing audits on highest risks.
- Governance riskAssessing governance attack scenarios.
- Integration riskRisks from external dependencies.
Quick answers
Web3 Threat Modeling at a glance
The essentials in brief. Every project is scoped individually — ask us for specifics.
- What is Web3 threat modeling?
- Structured threat modelling for Web3 systems — assets, adversaries, attack paths and prioritised mitigations.
- Who is it for?
- Typically Web3 startups, fintechs adding digital assets, and institutions exploring tokenization, stablecoins or on-chain settlement.
- What does Shivacha provide?
- Asset inventory
- Adversary modelling
- Attack trees
- Economic threats
- Mitigation plan
- Living model
- Which technologies are used?
- Solidity, Foundry, OpenZeppelin, MPC Cryptography, OWASP, Prometheus — chosen to fit your stack and constraints.
- How does the process work?
- Scope → Threat modelling → Review & testing → Remediation → Operate.
- What affects the cost?
- Contract complexity and number of chains
- Custody and wallet model
- Independent audit scope
- Indexing, analytics and back-office tooling
- Compliance integrations (KYC, AML, Travel Rule)
- Upgradeability and governance requirements
- How long does it take?
- A focused contract system or dApp MVP typically takes 8–14 weeks plus independent audit time; institutional platforms usually take 4–9 months.
- How do I get started?

Architecture
Engineered right from day one
The layers we typically design for Web3 security engineering, adapted to your stack and partners.
- Independent audits still matterOur work prepares for, and complements, third-party audits.
- Beyond the contractMany losses come from keys, frontends and operations, not code.
- Economic securityOracle manipulation and incentive attacks modelled explicitly.
- Response readinessPausing, upgrades and communication planned before incidents.
Delivery
How an engagement runs
- 1
Scope
Assets at risk, components and adversaries.
- 2
Threat modelling
Attack trees across contracts, keys, infrastructure and economics.
- 3
Review & testing
Code review, fuzzing, invariant testing and infrastructure checks.
- 4
Remediation
Prioritised findings and fixes, re-tested.
- 5
Operate
Monitoring, alerting and incident runbooks.
Security
Security built into delivery
Controls we apply by default on this kind of work — not a separate phase at the end.
Specification first
Roles, invariants and threat model documented before code.
Adversarial testing
Fuzz, invariant and fork tests plus static analysis on every change.
Key management
Admin keys in multisig or MPC with timelocks on sensitive actions.
Independent audit
Code prepared for — and we recommend — an external audit before mainnet value.

Frequently asked questions
When should threat modelling happen?
Early in design, and again before audits and major upgrades.
Who participates?
Engineers, product owners and security specialists; we facilitate and document.
Is this the same as a smart contract audit?
No. We provide security engineering, internal review and audit preparation. For production contracts holding meaningful value, independent audits by specialist firms remain essential.
Do you monitor deployed contracts?
Yes. We set up on-chain monitoring and alerting for anomalous transactions, privileged function calls and parameter changes.
