Using the Emergency Stop Pattern in Solidity

Smart contracts are the backbone of decentralized applications (dApps). They automate agreements and transactions on the blockchain, offering a tamper-proof and transparent environment. However, due to their immutable nature, bugs in a deployed smart contract can be disastrous. This is where the Emergency Stop Pattern comes in as a safety measure. What is the Emergency […]
