Blockchain Services
Coin, marketing site, wallet, and block explorer shipped by one engineer who reads contracts and copy with the same fluency. I handle the technology; counsel handles the law.
I do the engineering. Your counsel does the law.
Mineable coin or token, marketing site and whitepaper, non-custodial wallet, and block explorer — shipped end to end by one engineer. The legal perimeter belongs to your lawyer.
Engineering for founders launching a coin, token, or chain — the mineable coin or token, the marketing site and whitepaper, the wallet, and the block explorer — shipped by one engineer who reads contracts and copy with the same fluency. The work is the technology stack. The legal perimeter belongs to your lawyer, not to me.
Most blockchain launches go wrong in one of two places: the engineering is scavenged from forks no one understood, or the legal framing is improvised because the engineer was also pretending to be counsel. I will not pretend to be counsel. I will not give an opinion on whether a token is a security, whether an offering is registered, or whether your jurisdiction permits the launch. Those are your lawyer's calls. What I will do is ship a coherent technology stack — chain code, tokenomics in code, testnet validation before mainnet, a non-custodial wallet a non-technical holder can actually use, and a block explorer the community will ask for by week two.
I do not name specific token symbols on this page. I do not display logos of projects I have engineered for. The work speaks through the artifacts: testnet transactions, mainnet block heights, contract addresses, repository commits. The honest perimeter is structural: engineering scope is mine, legal scope is yours, and conflating the two is how blockchain projects end up with both bad code and bad paperwork.
James Henderson is a computer scientist with 25-plus years as an architect, engineer, and application designer. He approaches blockchain the way he approaches every other distributed-systems problem: as engineering, scoped honestly, with the legal and compliance perimeter left to the people licensed to handle it. He pairs disciplined engineering with current AI tooling — Claude Code, Codex, and a working judgment about when to trust them — to ship products faster and at higher quality than traditional staffing allows. There is no offshore team behind the page. The principal carries the work end to end: scope, build, deploy, support. A B.S. in Computer Science from the University of Houston and service in the U.S. Army ground the tone — evidence over assertion, plans before code, verification before delivery. The crypto-curious version of that tone is the same tone, with the same scope discipline.
I do the engineering. Your counsel does the law.
This is the single most important sentence on the page, and it is the one most blockchain founders are not told. The engineering scope is the chain or token, the marketing and whitepaper site, the wallet, the block explorer, the deployment infrastructure, and the operational scaffolding to run the network the day after launch. The legal scope is everything else — securities analysis, jurisdiction, registration, KYC and AML policy, sanctions screening, custodianship, tax treatment, marketing claims that could be construed as solicitation. I will not give an opinion on any of those, on this page or in a contract.
What I will do is build the technology stack as a coherent system: contracts written and reviewed against the chain's standards, tokenomics structured in code rather than in a slide, testnet rollout before mainnet, an explorer that lets your community verify the chain's behavior on their own, and a non-custodial wallet that a non-technical holder can actually use without losing funds.
What the four breakdown services cover
Coin or token launch
A launchable coin (proof-of-work fork from a vetted base) or a token (ERC-20 on Ethereum, SPL on Solana, equivalent on other chains) with tokenomics structured and verifiable on chain — base-chain selection, block-reward schedule, premine policy, difficulty adjustment, contract deployment, testnet rollout.
Project website and whitepaper site
The public face of the project — built on Laravel 12, Livewire 3, and Tailwind 4. Mobile-first, accessible, fast on Core Web Vitals. The whitepaper as a real document with a stable URL, a print-quality PDF, and structured data. Wallet-connect integration where the user journey actually needs it. No Web3 template that looks like every other launch.
Wallet application
A non-custodial wallet (web and mobile) — BIP-39 seed phrase generation and recovery, hardware-wallet integration where the chain supports it, transaction signing flows the user can verify before submission, send / receive / swap UX designed for a holder who is not a developer.
Block explorer
An Etherscan-style explorer for a custom chain, or a token-analytics dashboard for a token on an existing chain — chain indexer with block, transaction, and address ingestion, reorg handling, contract verification, address pages, an API surface for partners and exchanges.
- What you bring: legal cover (counsel of record on the offering), business and tokenomics decisions, treasury structure, marketing direction.
- What I bring: the engineering of all four artifacts and the operational scaffolding to run them.
- What I will not do: opine on whether your launch is permitted, registered, or compliant.
The background that informs this scope discipline is described on the about page. To scope a launch, get in touch.
What I ship
- Custom mining coin or token launch. Base-chain selection, proof-of-work parameter design, block-reward schedule, premine policy, genesis configuration, seed nodes, and mining client packaging where applicable.
- Project website and whitepaper site. Laravel 12, Livewire 3, Tailwind 4 build with mobile-first responsive design, accessibility, Core Web Vitals budgets, schema graph, and wallet-connect integration.
- Non-custodial wallet application. Web wallet on the application stack; mobile wallet via .NET 10 MAUI with a shared cryptographic core, BIP-39 seed handling, hardware-wallet integration where the chain supports it.
- Block explorer. Chain indexer with reorg handling and backfill capability, address and transaction pages, contract verification flow, token holder lists, and an API surface for partners and exchanges.
- Testnet validation and contract review. Testnet rollout before any mainnet event; contract review against the chain's standards; reproducible deployment scripts.
- Operational scaffolding. Node monitoring, RPC infrastructure, indexer ops, alerting on chain reorgs or contract anomalies.
- Documentation and handover. Runbook for every artifact; a second engineer can inherit the stack without a meeting.
Engagement model
Discovery runs two weeks: chain or token model selection, tokenomics review in code form, target-storefront and wallet UX scoping, infrastructure topology, and a written plan with milestones. Implementation runs in two-week sprints — testnet rollout before any mainnet event, with a working demo at the end of each sprint and a Git history you can read. Handover includes every artifact (chain or contracts, marketing site, wallet, explorer), the deployment infrastructure, a runbook for each, and a 30-day support window after mainnet launch. I do not give legal opinions; your counsel handles compliance, registration, and securities analysis. To scope a launch, get in touch.
