Self-execution, in the context of smart contracts and legal agreements, refers to the automatic and independent execution of the terms and conditions outlined in a contract when specific predefined conditions are met. Unlike traditional contracts that rely on human intermediaries, such as lawyers or notaries, to enforce and execute the terms, self-executing contracts use code and blockchain technology to execute actions autonomously.

Here are the key characteristics of self-execution in smart contracts:

Automated Execution: Self-executing contracts are programmed to automatically perform specific actions or transactions when the contract’s predefined conditions are satisfied. These actions can involve the transfer of digital assets, the updating of data, or triggering other contract-specific functions.

Code-Based Logic: The contract’s terms and conditions are written in code, which serves as the contract’s “law.” The code includes instructions for what should happen under various circumstances, and it operates without the need for human intervention.

Transparency: The code and the contract’s execution process are transparent and verifiable on the blockchain. Anyone can review the code and track the contract’s execution history on the blockchain.

Immutability: Once deployed on the blockchain, the code of a self-executing contract is typically immutable, meaning it cannot be altered or tampered with by any party. This ensures that the contract’s terms remain unchanged throughout its lifecycle.

Trustless Execution: Self-executing contracts operate in a trustless manner, meaning that participants do not need to trust a central authority or each other to ensure contract compliance. Trust is placed in the code and the underlying blockchain’s consensus mechanism.

Common examples of self-executing actions in smart contracts include:

• Automatically transferring cryptocurrency or digital tokens to a seller when a buyer pays for a product or service.
• Releasing funds from an escrow account to a seller when a shipping company confirms the delivery of goods.
• Executing options contracts when specific market conditions are met.
• Automatically paying insurance claims to policyholders when predefined conditions for a valid claim are satisfied.

Self-executing contracts are a fundamental feature of blockchain technology and play a crucial role in various blockchain use cases, particularly in decentralized finance (DeFi), supply chain management, and legal agreements where automation, transparency, and security are essential.
