🏦 Banks Rebuild What DeFi Already Built
**Financial institutions are wasting millions duplicating blockchain infrastructure that already exists.**
According to 1inch co-founder Sergej Kunz, banks are rebuilding systems for routing, liquidity, and execution - despite mature DeFi infrastructure already being in production and battle-tested.
**Key points:**
- Traditional finance is recreating on-chain systems from scratch
- DeFi protocols offer proven infrastructure ready for institutional use
- 1inch already powers swaps for major platforms including Binance, Coinbase, Ledger, MetaMask, and Trust Wallet
Kunz argues institutions should leverage existing DeFi technology rather than reinvent the wheel. The infrastructure is mature, operational, and increasingly powering both centralized and decentralized platforms.
