For engineering teams

Your Next BSV Feature Doesn't Need a Bitcoin Script Specialist. It Needs Bitcoin-SX.

Give your engineer (or contractor) an IDE that compresses the write-test-ship cycle for Bitcoin Script smart contracts, from locking script to production API to frontend, with full visibility into every transaction before it ever touches mainnet.

The problem

Mainnet is a one-way door. A locking script with one unconsidered branch doesn't throw an error you can patch. It strands funds permanently, and you find out after the broadcast.

The usual fix is hiring someone who has done it before. Fluent raw-Script engineers are scarce and priced accordingly, so a two-week feature becomes a recruiting problem, and the knowledge leaves when the contractor does.

The work is bursty too: deep capability for a few weeks around a launch, then almost none for a quarter. Usage-based cost fits that. Per-seat licences don't.

What you get

Validate before you broadcast: Step through every branch in simulation, so mainnet deployment stops being the first real test.
Less dependence on scarce experts: A competent engineer can be productive in SX without years of raw Script experience behind them.
The full stack, not just the contract: Each project generates a typed API and a React frontend alongside the locking script.
Git-based auditability: Contracts commit and push to your own repository, so review happens in the workflow you already have.
Usage-based, not per-seat: Cost tracks the weeks you're actually building instead of the headcount on a licence.
Client-side encrypted key handling: Keys are encrypted in the browser rather than held server-side.

The whole stack

Your engineer writes the contract. The API arrives with it.

Real endpoints, not a stub: server.ts is generated from the contract in the same project: deploy, create, unlock and read routes your application can call directly.
One source of truth: Because the API is derived from the contract rather than written against it, the integration layer cannot quietly drift out of step.
It leaves the building: Commit and push to your own repository, so this is reviewed in your normal pull-request process by people who never open the IDE.

Inside the IDE

Front tab: ContractDashboard.tsx. The generated React frontend that pairs with the API, ready to hand to whoever owns the product surface.

Simulator with contract-arguments panel. Every branch walked through with real arguments before deployment, rather than discovered on mainnet.

Transactions and broadcast panel. Testnet-first broadcast with the constructed transaction visible before it is sent.

Estimate the saving

What is that engineering time worth?

Put in your own numbers. This estimates the contractor time a shorter write-test-ship cycle gives back, and nothing more. It is a planning input, not a quote.

Estimated contractor time returned

$12,000

3 weeks × 5 days × $800 per day. Excludes any Bitcoin-SX cost, because public pricing isn't finalised yet.

Frequently asked questions

If something you need to know isn't here, just ask. We'd rather answer directly than leave you guessing.

Estimate your saving

Yes, that's a common setup. Bitcoin-SX is the environment, not the engineer. Because cost is usage-based rather than per-seat, bringing in a contractor for a sprint doesn't mean buying them a year-long licence.
