What is
Exploiting advance knowledge of pending transactions to profit, common in DeFi on account-based chains.
Front-running occurs when someone sees your pending transaction and submits their own with higher fees to execute first, profiting at your expense. This is common on account-model DeFi. Ergo's eUTXO model reduces the opportunity because transactions reference specific boxes and explicit outputs.
Common questions about this topic
Spectrum Finance is best treated as a historical Ergo DEX reference: the team published a sunset notice and froze contracts in February 2024. If you are studying old Ergo AMM flows, review Spectrum as a reference implementation, but do not assume it is an active venue for new swaps or liquidity. For any live trading, verify the current venue, liquidity, contract status, and official links first.
Building DeFi on Ergo starts with understanding the eUTXO model and ErgoScript. Unlike account-based chains, Ergo's box model provides deterministic execution, strong MEV-resistance, and predictable fee construction. Use Oracle Pools for price feeds, and study existing patterns from Spectrum Finance and SigmaUSD.
Ergo offers structural advantages for DeFi: MEV resistance by design, deterministic gas costs, and no protocol-level reentrancy by construction due to eUTXO. Ethereum has larger ecosystem and liquidity. Choose Ergo for security-critical applications, fair trading, and predictable costs. Choose Ethereum for maximum composability with existing protocols.
Ergo supports a broad ecosystem: use SigmaUSD, explore historical and current DeFi references, mix transactions with ErgoMixer where lawful, collect NFTs, mine with GPUs, bridge to other chains via Rosen, and build dApps with ErgoScript. Always verify current project status before sending funds to a third-party app.
