Crypto & Blockchain
SEMLIN supports blockchain projects and legitimate wallet recovery scenarios. We operate under strict ethical boundaries: proof of ownership is required, and we do not assist with any illegal access.
We help companies and individuals with legitimate crypto-related engineering work: integrating crypto payments, supporting smart contracts, and assisting with wallet recovery when ownership can be verified.
If you’re unsure whether your case qualifies, use the eligibility checklist below — then contact us.
Clear scope, controlled process, and practical engineering outcomes.
Recovery support when you can prove ownership and the scenario is lawful. We evaluate what information exists (partial seed, password patterns, backups, device constraints) and propose options.
In rare cases we can assist with reconstruction work — only under a controlled process and only for verified owners.
Accept crypto on your website or app with clear UX, safe flows, and real operational support.
Technical support for smart contracts and on-chain logic: implementation help, reviews, and integration patterns.
We assess system-level risk: key handling, signing flows, access control, and infrastructure exposure.
Request a review →We design flows that are compatible with business reality (logs, audits, operational clarity). We’re not a legal firm, but we engineer with compliance in mind.
Talk to us →We only work on lawful requests with verifiable ownership.
Exact requirements vary by case. We typically ask for a combination of signals:
A controlled process designed to reduce risk and protect confidentiality.
We confirm that the request appears lawful and eligible.
We request a minimal set of evidence to establish ownership.
We evaluate what’s missing and what recovery paths exist.
We agree on a controlled data-sharing process (no casual email keys).
We proceed with the agreed approach and report results clearly.
We will not ask you to email your private keys, seed phrases, or unencrypted sensitive material. For sensitive information, we use a controlled process that reduces exposure.
Transparent expectations before any work begins.
Some recovery efforts depend on incomplete information and may be probabilistic. We will explain feasibility, risks, and constraints before proceeding.
Any approach that increases risk beyond acceptable limits will be refused. Protecting ownership and preventing unauthorized access is the priority.
We focus on verifiable engineering work, not speculation or marketing language. If your case is eligible, we’ll treat it with seriousness and confidentiality.
Quick answers to common questions.
No. Recovery depends on the specific situation and the information available. We give a feasibility view up front.
No. We only work with verified owners and lawful requests.
We avoid collecting sensitive secrets. If a case requires sensitive handling, we use a controlled process and minimal exposure.
Yes. We can design and implement secure payment flows, confirmations, and operational tooling.
Yes — for suitable projects. We also accept bank transfer and PayPal.
