Just as **1inch** was born out of a hackathon weekend, **EVAA** was first built during the **Hack-a-TON x DoraHacks 2023** - a defining moment that helped shape **TON DeFi in Telegram**.

At the **Hack-a-TONx demo day**, EVAA's co-founder **Alex Sudeikin** introduced the TON blockchain's first-ever lending and borrowing protocol.
