Heinrichs Software Solutions is a veteran-owned engineering studio. We design and ship XRPL, EVM, Solana, Stellar, and x402 agent-payment systems for teams that need real engineering instead of another demo. Flat-fee scoped phases, typical delivery in weeks, code you can read and audit.
Most agencies pitching blockchain work have never deployed a production dApp. We have a public lab full of them. Our engagements are scoped against real code that already runs, not slideware. If you want to vet us before a call, the repos speak for themselves.
Every engagement starts with a free scoping call. No obligation, no deck, no sales pitch.
The most common engagements we take on, ordered by how fast they ship.
Three things that make the difference between a blockchain demo and a blockchain system that survives real users.
Our own payment gateway ships with 2,200+ tests and 99.91% coverage. Your build gets the same standard. You will not inherit a demo dressed up as a product, you will get code that passes review, runs in production, and does not surprise you at 2 AM.
We have production work across XRPL, EVM, Base, Solana, and Stellar. That means your project is not limited to whatever chain a single-chain shop knows. We pick the right chain for your use case and bridge across when it helps.
Every engagement is scoped to a fixed fee per phase with a delivery timeline written into the contract. No hourly creep, no discovery meetings that bill by the hour, no surprise invoices. Most builds land in two to six weeks, not two to six months.
From first call to shipped code in three clear steps. No billable hour games, no endless discovery phases.
Tell us what you want shipped. Chain, contract, integration, dApp, token launch, whatever it is. We will tell you on the call whether it is a fit, roughly how long it takes, and what it costs.
If we are a fit, you get a written scope with a flat fee and a delivery timeline. No hourly creep, no surprise invoices. Most engagements are two to six weeks end to end.
We build in the open with check-ins along the way. When we ship, you get the code, the docs, the deployment, and a walkthrough. Optional retainer for ongoing work if you want us around after launch.
XRPL, EVM chains including Ethereum and Base, Solana, and Stellar. We also have production experience with x402 agent-payment integrations and Axelar Interchain Token Service for cross-chain deployments.
Most scoped engagements land between two and six weeks. Token launches and x402 integrations can be as fast as one to two weeks. Larger dApps, games, or custom protocol work run longer and get priced accordingly.
Yes. We also ship custom AI integrations, AI chatbots, serverless backends on AWS Lambda, and full-stack web apps. If it runs on a computer, we can probably build it. The blockchain work is our specialty, not our ceiling.
Yes. We are SDVOSB certified and SAM.gov registered with six NAICS codes, which means we qualify for set-aside contracts. View the capability statement for contracting details.
Flat-fee builds on the chains and rails we know best.
Tokens, dApps, games, and custom protocol work on XRPL and the XRPL EVM sidechain. Portfolio includes an on-chain MMO and AMM demos.
Learn more →Turn any API into something an AI agent can pay for on demand. Built on the same x402 rails we shipped in BitBooth, multi-chain and production-hardened.
Learn more →ERC-20 deployed across EVM chains via Axelar Interchain Token Service. Same contract, multiple chains, one engagement. Ships in about a week.
Learn more →Blockchain games, AI integrations, chatbots, serverless backends, and full-stack web apps. If it is not on the standard menu, we can scope it.
