What is
DeFi?
DeFi (децентрализованные финансы) — финансовые сервисы на блокчейне без традиционных посредников.
DeFi включает обмены, кредитование, стейблкоины, деривативы и другие протоколы, реализованные через смарт‑контракты. Риски DeFi зависят от безопасности контрактов, оракулов, ликвидности и рыночных условий. Пользователю важно понимать механизмы и не пренебрегать управлением риском.

Getting Started
How to use Spectrum DEX on Ergo?
Connect your Nautilus wallet to Spectrum Finance, select tokens to swap, review the rate and slippage, then confirm. Spectrum uses AMM liquidity pools for instant trades. You can also provide liquidity to earn fees. All trades are atomic - they complete fully or not at all, with no front-running possible.

How to get started with Ergo?
Start by getting a wallet (Nautilus for browser, Terminus for mobile). Back up your seed phrase securely offline. Get some ERG from an exchange (Gate.io, KuCoin) or DEX (Spectrum). Make a test transaction. Then explore: try DeFi on Spectrum, check out NFTs, or dive into the technology if you're a builder.

How to build DeFi on Ergo?
Building DeFi on Ergo starts with understanding the eUTXO model and ErgoScript. Unlike account-based chains, Ergo's box model provides deterministic execution, no MEV by design, and predictable gas costs. Use Oracle Pools for price feeds, and leverage existing patterns from Spectrum Finance and SigmaUSD.
