From Dollar Crisis to Stablecoin Access: Onboarding Real-World Users with EIP-7702 & Passkeys
05-27, 17:30–17:55 (CET), Workshop

Bolivia is facing a real-world dollar shortage, people can’t access USD without paying 80% premiums. In this talk, I’ll explain how EIP-7702 and passkeys can onboard everyday users into stablecoin wallets without complex UX. This new Ethereum upgrade enables gasless, secure, smart-account-like transactions from regular wallets, perfect for solving real crises.


Crypto is often accused of lacking real-world use cases, but what happens when the financial system fails? In Bolivia, a severe dollar shortage means citizens can’t withdraw more than $100 per week in USD from their bank accounts. With black-market premiums exceeding 80%, the only accessible option for saving value is stablecoins.

But onboarding non-technical users into crypto wallets remains a major hurdle—especially in regions with low financial literacy, poor infrastructure, and no fiat onramps.

EIP-7702, proposed by Vitalik Buterin and launching with Ethereum’s Pectra upgrade, brings a powerful shift: it allows EOAs (Externally Owned Accounts) to temporarily act as smart accounts in a single transaction. That means users can access advanced features—transaction batching, gas sponsorship, social recovery, and passkey logins—without having to migrate to a smart contract wallet.

This talk will explore:
- How EIP-7702 works and why it matters for onboarding real people
- The role of passkeys and biometrics in making Ethereum UX familiar and safe
- How this tech stack (7702 + passkeys + stablecoins) can help communities bypass failing banking systems
- A real-world onboarding flow for Bolivians to access stablecoins via passkey-based login

As a Bolivian Solidity developer with 7+ years of experience, I’ve seen firsthand how Ethereum can be a financial lifeline. This talk it's about using Ethereum to solve real-world problems where they matter most.
