Which expenses are fixed, and which move with transfer volume?

Cost classification

Break-even is only reliable when payroll, rent, and retainers stay fixed while usage fees move with revenue. In the first operating year, that split matters because break-even arrives in Month 3.

Expense	Cost	Break-Even Treatment	Common Mistake
Engineering payroll	Fixed	Treat Year 1 technical wages as a monthly hurdle: $1.385 million annually, or about $115,417 per month.	Linking core engineering pay to transfer volume and overstating contribution margin.
Global office rent	Fixed	Include $12,000 per month from Month 1 through Month 60 in the fixed base.	Dropping rent from break-even because the team is product-led.
Legal and compliance retainer	Fixed	Include $8,500 per month as a standing operating commitment.	Treating compliance as event-driven when the model shows a monthly retainer.
Blockchain node and gas fees	Variable	Apply 8.0% of first-year revenue, falling to 5.5% by the mature year.	Modeling gas exposure as flat when it moves with transfer activity.
Cloud hosting and infrastructure	Variable	Apply 4.0% of first-year revenue, scaling down to 2.0% by the mature year.	Using one fixed hosting bill and missing usage-driven infrastructure load.
Smart contract security audits	Variable	Apply 5.0% of first-year revenue, declining to 2.0% as operations stabilize.	Classifying audits as one-time setup spend instead of ongoing break-even drag.
Customer support and community moderation	Variable	Apply 3.0% of first-year revenue, stepping down to 1.0% in the mature year.	Assuming support headcount stays flat as transfer users and tickets grow.
Marketing acquisition spend	Semi-variable	Use the $1.65 million first-year acquisition budget as planned spend, then test CAC-driven scaling.	Treating all marketing as fixed and missing spend needed to add buyers and sellers.

How does break-even shift from lean launch to base case and full-scale bridge operations?

Scenario table

Lean launch only covers fixed spend at about $356k in monthly revenue, so there’s no cushion. The base and full paths add room fast, but that room still depends on transfer volume, fee take-rate, and security overhead.

Planning assumptions only; actual break-even will move with transfer volume, fee take-rate, security work, and infrastructure overages.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$356k	$71k	$285k	80.0%	$0	At this level, the launch just covers fixed spend.
Base case	$2.41M	$500k	$285k	79.3%	$1.63M	Month 3 break-even gives a small cushion, but not much slack.
Full-scale launch	$27.81M	$3.04M	$865k	89.1%	$23.91M	Scale creates a wide cushion if volume and costs stay near plan.

What pushes the cross-chain bridge break-even point higher?

Stress test

The base plan clears break-even, but gas spikes, audit rework, and slower partner onboarding can move it fast. A 5-point margin drop lifts break-even to about $380k, and a 25% fixed-cost jump pushes it to about $445k.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$356k	$2.05M cushion	Healthy cushion if gas and audits stay in range.
Revenue shortfall	Year 1 average monthly revenue falls 20% to about $1.93M; margin stays at 80%.	$356k	$1.57M cushion	Still clears break-even, but slow partner onboarding cuts slack.
Fixed-cost increase	Fixed monthly spend rises 25% to about $356k.	$445k	$1.97M cushion	Security, legal, or infrastructure spend moves the target up fast.
Margin pressure	Contribution margin drops 5 points to 75% from gas spikes, audit rework, or support load.	$380k	$2.03M cushion	Small margin loss raises break-even without any sales drop.
Combined pressure	Revenue falls 20%, margin drops to 75%, and fixed monthly spend rises 25%.	$475k	$1.45M cushion	All three hits still leave a cushion, but the safety margin shrinks.

Before you commit to paid traffic, node scale-up, or office spend, are the contracts, redundancy, and cash cushion already in place for this bridge?

Founder checklist

Don't commit to paid traffic, node scale-up, or office spend until contracts, redundancy, and cash clear the Month 3 break-even test. On this model, Year 1 fixed load is about $147.4K a month and minimum cash hits $618K in Month 2, so runway has to survive a slip.

1Contract proofPaid launch

Verify audited contracts are signed and testable before paid traffic starts, so early spend does not chase unproven volume.

2Redundancy livePre-scale live

Keep validator, node, and RPC redundancy live before volume ramps, because transfer failures hurt trust and stall revenue.

3Fixed burn$147.4K/mo

Check that Year 1 fixed spend sits near $147.4K a month, including the $8.5K legal retainer and $4K cybersecurity insurance, before you add more headcount.

4Margin check80%

Make sure Year 1 variable costs stay around 20% of revenue, which leaves about 80% contribution before fixed costs.

5Cash cushion$618K

Hold at least $618K of cash through Month 2, since that is the model's low point and a launch miss can freeze the build.

6CAC fit$450 / $25

Match Year 1 seller and buyer budgets of $450K and $1.2M to CAC near $450 and $25, and pause scale if break-even slips past Month 3.
