How a freelance developer in Lisbon receives USD payments and earns 4.3% yield on idle cash
Marco Silva replaced three separate financial tools with a single Nano Wallet account for invoicing, receiving payments, and earning yield between projects.
“I used to joke that managing my money was a part-time job. Now I check the dashboard once a week, and my idle cash actually works for me. The yield alone covers my coworking space membership.”
The Challenge
Marco Silva is a full-stack developer based in Lisbon who contracts with US-based startups. His clients pay in USD, but his living expenses are in EUR. Before Nano Wallet, his payment workflow involved three separate tools: a Wise account to receive USD wires, a Portuguese bank account for EUR spending, and a DeFi wallet where he manually parked stablecoins to earn yield between projects.
The friction was constant. Wise transfers took 1–2 days. Converting USD to EUR at the right moment required monitoring exchange rates. And moving funds to a DeFi protocol meant gas fees, wallet management, and the anxiety of self-custody. Between projects — which could last 2–6 weeks — his USD sat idle earning nothing in his Wise account.
Marco estimated he was losing $1,200–$1,800 per year in unnecessary fees and missed yield.
The Solution
Marco opened a Nano Wallet account in under 15 minutes. He now gives clients his Nano Checking account details (routing + account number) for direct ACH deposits. When payments arrive, he keeps a working balance in USD for upcoming expenses and moves the rest into the USDC yield wallet, which earns 4.3% APY.
When he needs EUR, he converts USD to USDC and sends it to his European exchange account for conversion — or uses the Nano Visa debit card for direct purchases. The entire workflow lives in one dashboard.
The key difference from his old setup: there's no idle cash. Every dollar is either in a checking account ready for use or in the yield wallet earning interest. And he doesn't need to manage private keys or worry about smart contract risk — the yield is generated through institutional-grade strategies managed by Nano Wallet.
The Results
After 8 months on Nano Wallet, Marco's financial operations are significantly simpler. He consolidated three tools into one, eliminated approximately $140/month in transfer and conversion fees, and earned $1,840 in USDC yield on cash that would have previously sat idle.
His average time spent on financial administration dropped from roughly 3 hours per week to about 20 minutes. He no longer monitors FX rates obsessively or manually moves funds between protocols.
Marco has since referred four other freelancer friends to the platform, two of whom have also switched from their previous multi-tool setups.
