Base Europe

I sent €5,000 across 8 payment rails. The fastest arrived in 2 seconds. The slowest took 5 days. And the fees? $235 difference on the exact same transfer. Here's what that experiment taught me about the future of money. Rail #1: USDC on Base: 2 seconds, $0.01 fee The recipient received $5,882.50. Rail #8: SWIFT Wire: 5 days, $25 + 1.5% FX markup The recipient received $5,794.26. Same sender. Same recipient. Same €5,000 on Monday. One settled before I closed my laptop. The other arrived on Friday. 𝗡𝗼𝘄 𝘇𝗼𝗼𝗺 𝗼𝘂𝘁. In 2025, stablecoins processed $33 trillion in volume. Visa processed $16.7 trillion. For the first time in financial history, a "crypto" rail moved more value than the world's largest card network. Most people missed it. The financial press barely covered it. But inside every major payment company, someone is reading those numbers and losing sleep. 𝗪𝗵𝘆 𝗶𝘁 𝗺𝗮𝘁𝘁𝗲𝗿𝘀 𝗳𝗼𝗿 𝘆𝗼𝘂𝗿 𝗻𝗲𝘅𝘁 𝗽𝗮𝘆𝗺𝗲𝗻𝘁 Ask anyone: "Is paying by card instant?" They'll say yes. They're wrong. What's instant is the authorization, the 2-second green checkmark that tells the merchant "this card is legit." The actual money? It sits in batch processing queues for 1 to 3 days, hopping between acquirers, schemes, and issuing banks on infrastructure built in the 1970s. Stablecoins collapse that gap. Authorization and settlement happen in the same transaction. No T+2. No batch windows. No correspondent banks taking a cut. That's why the fee on my €5,000 transfer dropped from $25+ to $0.01. 𝗪𝗵𝗼'𝘀 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗰𝗼𝗺𝗽𝗲𝘁𝗶𝗻𝗴 𝘄𝗶𝘁𝗵 𝘄𝗵𝗼? Most people frame this as "crypto vs banks." It's not. The real war is: - Stablecoin rails vs Visa & Mastercard (the interchange model) - Stablecoin rails vs Swift (correspondent banking) - Stablecoin rails vs Stripe (merchant acquiring) And the incumbents know it. Mastercard added Polygon Labs, Ripple, Solana, and Aptos to its Crypto Partner Program. Visa is already settling USDC through Circle. PayPal shipped its own stablecoin (PYUSD). They're publicly calling stablecoins a threat while privately integrating them into their stack. Classic frenemy move. APMs were the first wave. Stablecoin rails are the second. Huge thanks to Benji Audigé for the great work he put into this during the hackathon I organized 🫡 PS: I post weekly about payments, stablecoins, and the reality of building a payment startup.
