In the financial world, an execution venue can be any location or platform that allows for the completion of trades. This includes various types of markets, such as exchanges (stock or crypto exchanges), alternative trading systems, dark pools, and over-the-counter (OTC) markets. Each execution venue has different characteristics, including speed, liquidity, fee structures, and regulatory requirements. In web3 finance, execution venues enabling trades in decentralized finance (DeFi) such as decentralized exchanges (DEXs) have emerged, allowing peer-to-peer trading of assets without the need for a central authority.
