In the context of Web3, escrow refers to smart contracts that automatically hold and release cryptocurrencies or assets based on predefined conditions. This eliminates the need for trust between parties involved in a transaction, as the automated system ensures compliance with the agreed terms before transferring the assets. Escrow mechanisms are particularly useful in peer-to-peer transactions, such as buying or selling NFTs or digital assets, where both parties need assurance that the transaction will be completed as per their agreement.
