The Operating System for Stablecoins: Beyond the Crypto Hype | Stone Atwine

For an operator moving millions across borders, Stone Atwine has come to understand where there’s real value to be created and where hype dominates. For him, having built his Fintech chops in a Mobile Money region, the value proposition for Stablecoins became evident almost immediately.  Why manage 10 different bank accounts and wait days for SWIFT when you can run a continental treasury from a single USDT buffer?

Stone Atwine is a battle-tested fintech veteran who was talking about unit economics long before the "Venture Winter" made it cool. From solving "black tax" remittances for his grandmother to building Eversend on a lean $1.2M seed round, Stone has transitioned the company from a B2C wallet to the high-leverage B2B infrastructure powering African trade.

This conversation moves away from the chatter about web3 towards how companies are solving real treasury challenges with stablecoins. Stone breaks down his "4-Level" payment architecture framework, a system that replaces traditional pre-funding with "Just-in-Time" liquidity. He explains why Eversend has completely abandoned SWIFT for internal operations and why the future of money looks like e-money on open rails.

In This Episode, You Will Hear:

• The Death of SWIFT: Why Eversend no longer uses traditional bank messaging for internal treasury.

• Centralized Stablecoin Treasury: Moving from fragmented local accounts to a single USDC buffer for 30-minute rebalancing.

• The Settlement Tension: Why "Just-in-Time" instant settlement can sometimes be costlier than traditional netting.

• Global Use Cases: Why players like Deel and Wise are the perfect fit for stablecoin infrastructure.

• Evaluating the Stack: What banks need to learn about custodial services like Fireblocks and security audits.

• The Issuance Arms Race: Why JPMorgan and Citi, not just Tether, could dominate the future of yield-bearing reserves.

• CBDCs vs. Private Stablecoins: Why the BIS mBridge is a "brilliant idea" but local stablecoin mandates may be the more practical path.

"Stablecoins are basically e-money... but with a global ability to move on a blockchain ledger instead of a telco's ledger. It’s just-in-time financing for the real world."
