The merchant crypto adoption problem
Bitcoin reached widespread name recognition years ago, and stablecoins like USDC and USDT now hold over $150 billion in combined market cap. Yet the percentage of merchants who accept any form of crypto payment remains in the low single digits. The gap is not consumer demand: surveys consistently show that 15 to 20% of US consumers who own crypto would use it to pay for goods and services if the option existed. The gap is merchant infrastructure. Accepting crypto today means choosing between a clunky hosted checkout (BitPay), building a custom integration with an exchange, or hoping your e-commerce platform has a native plugin. None of those options are good enough for a mainstream merchant.
Stablecoin checkout for e-commerce
The first practical crypto payment product for mainstream merchants is stablecoin checkout: let customers pay in USDC or USDT, auto-convert to USD at the point of settlement, and deposit to the merchant's bank account within one business day. The merchant never holds crypto risk. The customer gets to spend their stablecoin holdings. The payment processor takes 0.5 to 1.5% versus Stripe's 2.9%. Stripe launched stablecoin payments in 2024 but at enterprise scale; the SMB-focused version with a simple Shopify plugin and a clean merchant dashboard is still underbuilt.
Multi-currency crypto wallets for remote-first companies
A software company with a remote team in five countries paying contractors in local currencies can save 3 to 5% per payment by settling in USDC and having contractors convert locally. The operational tool that makes this work is a corporate crypto wallet: multi-signature approvals, contractor onboarding with KYC, automated payroll scheduling, and a fiat off-ramp in each contractor's country. Request Finance and Gilded exist in this space but serve crypto-native companies; the tool for a traditional SMB that wants to add a crypto payroll option alongside their existing wire transfers is missing.
On-chain invoicing for freelancers
A freelancer who works with crypto-native clients (DAOs, Web3 startups, NFT projects) has no standard invoicing tool that handles crypto billing natively. Request Network built the protocol; the application layer that gives a freelancer a clean invoice UI, automatic payment status tracking, and a tax export at year end is still thin. An on-chain invoicing tool for freelancers, priced at $15 per month or 0.5% per invoice, solves a real pain for the 200,000+ freelancers actively working with crypto-native clients.
Crypto treasury management for startups
A startup that raised a crypto round or holds BTC or ETH on its balance sheet needs treasury management tools that traditional CFO software does not provide: real-time portfolio valuation, cost basis tracking for tax purposes, yield on idle stablecoin holdings, and a clear audit trail for the board. Anchorage and Fireblocks serve institutional clients at high minimum sizes. A founder-friendly crypto treasury dashboard at $200 to $500 per month serves the 10,000+ companies that hold crypto as a meaningful balance sheet item but do not qualify for institutional-grade services.
DeFi yield on idle working capital
Businesses with working capital sitting in a bank account earning 0.01% interest can earn 4 to 6% APY by deploying those funds into DeFi lending protocols or stablecoin yield products. The risk is real but manageable with appropriate protocols. A product that automates this for SMBs, moving idle cash above a configurable threshold into a vetted stablecoin yield strategy and back to the operating account before payroll, charges a percentage of yield generated. At 15% of yield on $500K of average deployed capital, you earn $3,000 to $4,500 per customer per year.
What to build first
The stablecoin payroll tool for SMBs with international contractors has the clearest immediate value: the savings are real, the customer acquisition path is through LinkedIn and remote work communities, and the regulatory complexity is manageable with a licensed money transmitter partner. Start with one country pair (US to Philippines or US to Mexico) and one payment method. Price at $99 per month plus $1 per payout. Use the Runway Calculator to model the path to $1M ARR at different conversion assumptions.
The competitive landscape
Coinbase Commerce and BitPay handle merchant checkout. Request Finance and Gilded handle crypto invoicing. The open areas are SMB-focused stablecoin payroll, crypto treasury management for sub-$50M companies, and DeFi yield automation for working capital. Each is a focused product for a specific buyer, not a general crypto wallet play.
