A smart contract is a software algorithm designed to automate the execution of agreements on a blockchain. The terms of the contract are verified and carried out by program code, which eliminates the possibility of incorrect or arbitrary execution. The contract is either carried out exactly according to its built-in logic or not carried out at all.

The main feature of smart contracts is self-execution without the involvement of intermediaries. When the predefined conditions occur, the code automatically triggers the corresponding actions: for example, transferring funds or changing the state of the network. All operations are recorded in the distributed ledger and available for verification, which ensures transparency and resistance to tampering.

Key properties of smart contracts

• Automatic execution when the specified conditions are met;
• No need for a trusted intermediary;
• Transparency and verifiability of operations on the blockchain;
• Immutability of the logic after the contract is deployed.

Smart contracts underpin many areas of the crypto industry, from token issuance to decentralized applications and financial services. Users can create their own contracts by describing the desired logic. At the same time, it is important to remember that errors in the code are also executed automatically, so the reliability and auditing of contracts are of great importance.
