Inspiration

Watched fintech friends waste days on Web3 auth for lending prototypes—seed phrases, wallets, key management. We knew banks needed frictionless DeFi onboarding to go mainstream.

What it does

Crypto solution for the real world. Invisible Web3 bridge for banks: onboard users to Starknet via social login (Google)—no wallets, seed phrases, gas fees, or extensions. End-to-end, we truly open the doors to decentralized finance with secure MPC key management and instant lending access.

How we built it

• Tech stack: Next.js (frontend), Node.js + Supabase (backend).
• Current stage: Ramping to production-ready MVP.
• Team: Beyond software—business mindset for partnerships and real-world scale.

Challenges we ran into

Slow debugging in early development.

Accomplishments that we're proud of

Social login wallet creation, zero-fee txs (via paymaster), and seamless lending UI—crypto for everyday users, ready for banks.

What we learned

Social login + MPC = real-world crypto adoption; paymasters eliminate gas barriers for mass DeFi entry.

What's next for OpenTheDoorz.com

Polish MVP, partner with banks on social login onboarding to bring real-world users into decentralized finance.
