The protocol is sound, but the product still asks too much of a new or cautious user.

When the current product is not enough
You may be here because...
Balances, transactions, signatures and network states are visible without being easy to understand.
Your team needs someone who understands the technical context as well as the product experience.
How Flat 18 helps
One route from uncertainty to a product you can move forward.
We work across the product decisions, interface and software delivery that need to join up for the next release to make sense.
01
Find the trust gaps
Identify where a person must take a leap of faith because the product does not yet explain enough.
02
Design readable flows
Make signing, sending, swapping, receiving and recovery states more legible without over-simplifying them.
03
Ship the product layer
Build interfaces, integrations and web applications that connect the protocol to real people and operational teams.
Selected work
Product work built around real complexity.
These are not templates. Each project starts with the people, decisions and constraints that make the product difficult to get right.
Bitcoin payments
BTCPay Server
Clarified a self-hosted payments project so merchants could better understand the product and take the next step.
Wallet research
WalletScrutiny
Reshaped a large review catalogue so readers could move from a verdict to the underlying evidence.
Merchant payments
ForgingBlock Dashboard
Refined scattered payment data into a focused view of paid invoices, open items and payout status.
Before we start
Useful questions, answered plainly.
If the work sounds familiar, send the current product or idea. We’ll help you find the next sensible move.
Do you only work with Bitcoin?
No. We work across Bitcoin, payments, DeFi and broader Web3 products when the product challenge is a good fit.
Can you improve an existing dApp or wallet interface?
Yes. We can audit the flow, improve the interaction model and build the changes alongside your protocol or backend team.
Do you provide smart-contract audits?
No. We focus on product design, application development and the experience around technical systems. Smart-contract security should be handled by a specialist auditor.
