Build a DeFi App on Ergo
From concept to testnet prototype, then audit-gated mainnet planning
Ergo's eUTXO model removes several common DeFi vulnerability classes — including the protocol-level reentrancy class — while keeping transaction state explicit. Application-level bugs are still possible, so production deployments still need review, limits, and monitoring.
問題
Traditional DeFi on account-based chains is plagued by exploits, unpredictable gas costs, and MEV extraction. Developers spend more time on security audits than building features.
解決方案
Ergo's eUTXO model provides deterministic execution, removes the protocol-level reentrancy class, and reduces common MEV patterns. ErgoScript is expressive yet auditable, but production deployments still require careful review.

Case Studies
Spectrum Finance (historical)
Decentralized exchange built on Ergo's eUTXO model with AMM and order book functionality. Listed here as a historical reference: Spectrum Finance issued a formal sunset notice and the contracts have been frozen since Feb 2024.
