Common questions about this topic
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.
eUTXO (Extended Unspent Transaction Output) is Ergo's smart contract model that extends Bitcoin's UTXO with programmable logic. Each 'box' contains ERG, tokens, data registers, and a guarding script. Transactions consume boxes and create new ones, enabling deterministic execution, parallel processing, and no reentrancy attacks.
MEV (Maximal Extractable Value) is profit extracted by reordering, inserting, or censoring transactions - think front-running and sandwich attacks. Ergo's eUTXO model provides structural MEV resistance: transactions reference specific boxes (UTXOs), making reordering attacks much harder. There's no shared global state to exploit like in account-based chains.
Ergo supports a full ecosystem: trade on Spectrum DEX, use SigmaUSD stablecoin, mix transactions with ErgoMixer, collect NFTs on SkyHarbor, mine with GPUs, lend/borrow on DuckPools, bridge to other chains via Rosen, and build dApps with ErgoScript. It's a complete platform for decentralized finance and applications.
