Review, Remediation и Upgrades

Review

Ключевая техническая и security-оценка

GreyBound Review is a technical and security assessment of a Bitcoin system that already exists: wallet, signing path, node, backend, indexer, or side chain. Do this before mainnet funds or a public launch. The client gets an executive summary, a risk register, a remediation roadmap, and a validation plan. This is not a public contest report.

Review is for architecture and trust boundaries. Remediation is for issues already named. Upgrade is for new features in a product that already runs.

Клиент получает:

• Executive Summary (общее состояние системы, ключевые риски, немедленные приоритеты, готовность к заявленной цели)
• Findings / Risk Register (проблема, затронутый компонент, техническое влияние, влияние на безопасность/надёжность, severity, evidence, условия для эксплуатации/отказа, рекомендуемая remediation)
• Prioritized Remediation Roadmap (приоритетная roadmap Remediation)
• Architecture / Engineering Recommendations (архитектурные / инженерные рекомендации)
• Validation Plan (тесты, security-валидация, configuration checks, regression checks, повторный review при необходимости)

Remediation

Устранение технических и security-проблем

GreyBound Remediation fixes Bitcoin infrastructure issues the client already knows or that Review found. The work is code, configuration, architecture, and operations on the running system, then checks and handoff.

Клиент получает:

• Scoped Fix Plan (согласованный список проблем, приоритет, acceptance criteria и change risk)
• Implemented Fixes (изменения кода, конфигурации, архитектуры и операций по необходимости)
• Verification Evidence (тесты, security checks, configuration checks и regression results)
• Change Documentation (что изменилось, почему, как эксплуатировать, и residual risk если есть)
• Handoff for Follow-up (чёткие следующие шаги, включая целевую проверку или повторный review при необходимости)

Upgrades

Разработка функций и усиление продукта

GreyBound adds features to a Bitcoin wallet or signing stack that already ships. The work goes into the live codebase: descriptors, PSBT flows, multisig, hardware-signer paths, fee and coin selection, and the backend or indexer the wallet uses.

This is for

• a mobile, desktop, or extension Bitcoin wallet that already exists
• a signing service or non-custodial payments path that already exists
• Bitcoin or a side chain the client already runs

This is not for

• building a new wallet from nothing
• a template wallet for many chains

Клиент получает:

• Feature Scope & Design (требования, интерфейсы, ограничения и Bitcoin/security-соображения)
• Implementation on the Existing Product (функции в существующий код)
• Tests & Validation (unit/integration coverage, security-проверки и защита от регрессий)
• Documentation & Handoff (как работает, как эксплуатировать и как расширять)
• Upgrade Path Notes (роллаут, совместимость и production readiness изменения)

What we need from you

To start, we need the running system:

• what is live today
• what must not break
• what you want changed or proved
• who can answer questions on the repo

If the system signs or moves bitcoin, we need enough of the signing path to trace one transaction from screen to bytes. If you cannot share that yet, say so. We will say what we can still do.

What the work is

A Review maps trust boundaries and names what can lose funds.

Remediation changes the running code or config and shows the check.

An Upgrade adds a feature in that same codebase.

What we decline

We do not produce a public audit PDF meant only for a launch page.

We do not take a chain we do not operate.

We do not build a new wallet from nothing for every network.
