Architecture Sprint Guide: What $3K to $5K Delivers

Solana builds rarely fail on the code. They fail on decisions nobody wrote down.

Who holds the upgrade key? Which integration can stall launch? What does "done" mean? Teams that start coding before they answer these pay for the answers twice.

Our architecture sprint costs $3K to $5K and settles those questions on paper first. You get five written artifacts and one decision: build, narrow the scope, or stop. Below is each artifact, a worked example from a real case study, and where the sprint ends.

Who an architecture sprint is for

The sprint fits teams that need a credible Solana plan before they fund the build. You have a real problem and a budget. You don't yet have a plan you'd bet that budget on.

You're a good fit if one of these sounds familiar:

• Your token economics or fee model isn't settled, and it changes what the program must enforce.
• You haven't decided who controls program upgrades, treasury moves, or admin actions.
• Your product depends on an integration you've never run in production, such as a DEX, an oracle, or a data feed.
• You have two quotes that differ by a factor of three, and you can't tell why.

You're not a good fit if the scope is already written and agreed. In that case, go straight to a production build. If a live system is breaking, a reliability and rescue sprint is the better start.

What to bring to the scoping call

You don't need a spec. You do need answers, even rough ones, to a short list:

• Who owns the problem and signs off on the result?
• What's the one workflow the product must get right first?
• Which chain assumptions and integrations are already fixed?
• What's the approved budget and the delivery window you're working toward?

Leave the implementation choices open. Deciding them is the sprint's job.

Every sprint begins with the first two steps of our published process: Diagnose and Architect. Diagnose confirms the problem, the buyer, the budget, the urgency, and the acceptance conditions. Architect maps system boundaries, dependencies, failure modes, exclusions, and the delivery plan.

The five artifacts, one by one

These are the five items listed on our process page for the sprint. Nothing else is promised, and nothing here is padding.

1. Scoped problem statement

One page. It names the problem, the accountable owner, the users, and the budget. It also lists what's out of scope, which matters as much as what's in.

A good problem statement is short enough to read aloud in a meeting. If your cofounder and your lead engineer disagree with it, you've found the first risk.

2. Architecture and integration map

This map draws the system boundary. It shows which programs hold state, which accounts each one owns, and who signs each privileged action.

For Solana work that means program accounts, PDAs, and the upgrade authority for every deployed program. Every external service your product calls gets a box too, along with what happens when it's down.

3. Risk register

Each risk gets a likelihood, an impact, a named owner, and a mitigation. Typical entries cover authority design, an integration you don't control, bot activity at launch, and data you can't afford to lose.

4. Acceptance criteria

These are testable statements that define done. If a criterion can't be checked by a test or a recorded run, we rewrite it until it can.

5. Build plan and estimate

Milestones, dependencies, exclusions, and a cost estimate. The estimate is built from the first four artifacts, so you can see where each line comes from.

That traceability is the point. When a line in the estimate looks high, you can follow it back to the risk or criterion that caused it, and decide whether to keep it.

A worked example: the pump.science scope

Our pump.science case study is one of 22 on our work page, all labelled historical. It was a full build, not a sprint. Its published scope still shows what a sprint has to untangle before code ships.

Here's what we built. Each longevity compound got its own token on a bonding curve. Funds flowed to contract research organizations to start experiments. A data pipeline streamed lab results to the platform in real time.

The smart contracts handled dynamic fee models to deter bot manipulation. They also moved liquidity to Meteora automatically at set milestones.

Extensible data schemas let the platform add new model organisms later.

Run that scope through the five artifacts and the sprint questions show up fast. Who can change the fee model after launch? What happens if the liquidity migration fails halfway? What does the platform show when the lab feed goes quiet?

Here's how acceptance criteria for that scope would start today:

# acceptance.yaml (illustrative, written for this article)
- id: AC-01
  given: a compound token reaches its migration milestone
  then: liquidity moves to the DEX pool in one transaction
  evidence: devnet run log with signature
- id: AC-02
  given: the migration transaction fails
  then: funds stay on the curve and an alert fires
  evidence: forced-failure test in CI
- id: AC-03
  given: the lab feed sends no data for 30 minutes
  then: the experiment page shows a stale-data banner
  evidence: recorded run against a paused feed

Every entry names its evidence. That's the habit the sprint builds.

What the architecture sprint is not

The sprint is a planning engagement. Knowing its limits up front saves you from buying the wrong thing.

• It is not a prototype. You get documents and a decision, not a deployed program. A demo built before the risks are mapped tends to hide the risky parts.
• It is not a security audit. The risk register flags where an independent audit is warranted. The audit itself, with its price and schedule, comes from the reviewer you choose.
• It is not a fixed timeline. Our process page lists the sprint timeline as scoped after qualification. We don't promise a start or delivery date before that.
• It is not a quote for every future phase. The estimate covers the build plan in front of you. RPC, indexing, monitoring, legal advice, and support sit outside the base build unless the scope names them, as our cost guide explains.

What moves the price inside the $3K to $5K band? Unsettled economics, chain selection, integration count, authority design, and unclear product ownership. The more of those that are open, the more work the sprint has to do.

After the sprint: build, narrow, or stop

The sprint ends with a decision, and all three outcomes count as success. Each one is cheaper to learn now than in the middle of a build.

• Build. The plan feeds a Production Build, which runs $10K to $40K. The acceptance criteria and estimate become the starting point for that proposal.
• Narrow. The plan shows the full scope is too large or too risky. You cut it to one complete workflow that proves the hardest assumptions, then build that.
• Stop. The risks outweigh the budget, or the integration you depend on can't do what you need. Learning that for $3K to $5K beats learning it halfway through a build.

Whichever way it goes, the next step is written down before anyone spends more. Payment follows the same rules for every engagement.

You get a written proposal first. It confirms the statement of work, timeline, exclusions, and fixed quote after a qualified scoping call.

The standard structure is 50% deposit and 50% on accepted delivery. For larger scopes, a proposal may define milestones instead.

FAQ

How much does a Builderz architecture sprint cost?

An architecture sprint costs $3K to $5K. The final price is set in a written proposal after a scoping call. Open questions in economics, chain choice, integrations, and authority design push it toward the top of the range.

How long does an architecture sprint take?

The timeline is set in the proposal, after qualification. We don't publish a fixed duration because the sprint depends on how many open questions your scope carries. You'll know the timeline before you pay anything.

Do I pay before I see a proposal?

No. You get a written proposal before any payment. It confirms the statement of work, timeline, exclusions, and fixed quote. The standard structure is then 50% deposit and 50% on accepted delivery.

Can I skip the sprint and go straight to a production build?

Yes. Skip it if your scope, acceptance criteria, and authority design are already written and agreed. A production build runs $10K to $40K against written acceptance criteria. If those documents don't exist yet, the sprint is how you get them.

Does the architecture sprint include a security audit?

No. The sprint doesn't include an independent security audit. The risk register flags where value at risk or privileged authority makes one worth paying for. The audit's price and schedule come from the reviewer you pick.
