Process & Quality

A disciplined workflow for shipping secure blockchain products

Our process reduces ambiguity, makes risk visible early, and keeps delivery consistent from first specification through post-launch operation.

Detailed engineering workflow

Every project follows the same quality spine, then adapts to product complexity and team structure.

1. Specification Discipline

  • Product requirements converted into explicit contract and integration behaviors
  • Critical invariants documented in plain language before implementation starts
  • Failure modes listed with mitigation options and ownership
  • Approval checkpoint with stakeholders before code execution

Result: engineering and product teams align on expected behavior and acceptable tradeoffs.

2. Repository Hygiene

  • Conventional branching and commit standards with linked tickets
  • Protected main branch and mandatory review policies
  • Template-based pull requests with risk and migration notes
  • Deterministic environment setup scripts for local and CI parity

Result: reproducible development flow and faster onboarding for all contributors.

3. CI Quality Gates

  • Linting, formatting, and static analysis run on every pull request
  • Unit and integration tests with failure visibility and artifact retention
  • Gas snapshot diffs for high-volume user methods
  • Secret scanning and dependency checks for supply-chain safety

Result: risky changes are blocked automatically before merge.

4. Testing Strategy

  • Unit tests for deterministic business logic and permission boundaries
  • Fuzz/property tests for invariant preservation under unpredictable input
  • Integration tests for wallet, indexer, and backend coordination
  • Fork/staging tests for deployment and migration readiness

Result: behavior is validated at both module level and system level.

5. Review Mechanics

  • Dual review for critical contract modules and privileged operations
  • Design review for architecture-impacting changes before coding
  • Pre-merge checklist for migration, monitoring, and rollback requirements
  • Change logs that are readable by both engineering and operations teams

Result: decisions remain auditable and context is preserved for future upgrades.

6. Deployment and Handoff

  • Versioned deployment scripts with deterministic artifact hashes
  • Verification and post-deploy sanity checks by environment
  • Runbooks for incident response and rollback activation
  • Owner transfer plan and support protocol for launch week

Result: launches are controlled events, not late-night improvisation.

Security Mindset

Security as an ongoing operating model

Security is not isolated to audits. It is designed into architecture choices, release processes, and incident readiness.

Threat Modeling

Each system has a living threat model that tracks trust assumptions, possible abuse paths, and blast-radius boundaries.

  • Actor-based attack scenarios (external + privileged)
  • Asset classification by sensitivity and recoverability
  • High-risk decision points mapped to controls

Access Control

Permissions are explicit, minimal, and auditable. We avoid overpowered owner accounts and undocumented admin actions.

  • Role matrix with approved action boundaries
  • Time locks for high-impact protocol changes
  • Separation of deployer, operator, and governance powers

Upgrade Strategy

Upgradeability is planned with storage safety, migration scripts, and public communication requirements.

  • Storage layout tracking and compatibility checks
  • Staged rollouts and rollback preparation
  • Governance review windows for critical updates

Monitoring and Incident Response

Production systems include actionable alerts, severity tiers, and owner-ready runbooks before launch.

  • Real-time checks for privileged changes and abnormal flows
  • Incident command roles and communication templates
  • Postmortem process with measurable remediation deadlines
Quality Gate

Definition of Done checklist

A milestone is not considered complete until every checkpoint below is met.

  • Specification and accepted behavior are documented and versioned
  • All relevant tests pass in CI, including fuzz/property suites for critical paths
  • Gas and performance impact is measured for user-facing methods
  • Security assumptions and known limitations are recorded
  • Deployment scripts and configuration are reproducible across environments
  • Monitoring hooks and alert thresholds are active
  • Rollback and incident procedures are confirmed with owners
  • Handoff package includes architecture notes, runbooks, and open risk register
Tooling

Core engineering toolchain

Tool choices depend on chain and system constraints, but our baseline quality controls remain consistent.

Contract Tooling

  • Foundry and Hardhat for compilation, testing, and deployment automation
  • Gas reporters and snapshot comparisons in CI
  • Scripted environment validation before deployments

Static Analysis & Linting

  • Solhint and language-specific linting rules
  • Slither/static analyzers for anti-pattern detection
  • Code formatting and style checks as merge blockers

Quality & Verification

  • Coverage tracking and trend reporting
  • Artifact signing and bytecode verification workflows
  • Environment-aware smoke tests post-deployment

Product Layer

  • Typed API schemas for indexer/backend/frontend reliability
  • Error telemetry for wallet and transaction states
  • Release pipelines with rollback-safe versioning

Monitoring Stack

  • On-chain event subscriptions with threshold alerts
  • Runtime dashboards for infrastructure and job health
  • Incident timelines and postmortem evidence retention

Documentation

  • Architecture Decision Records for non-obvious tradeoffs
  • Operational runbooks for support and engineering teams
  • Handoff bundles for audits and long-term maintainers
