No lawyers chasing paperwork, no banks delaying transactions, and no middlemen taking charges. These are what smart contracts in cryptocurrency promise. These programs function on blockchain networks like Ethereum, automatically setting rules, moving assets, and keeping records of the outcomes with mathematical accuracy.<\/p>\n<p>In this beginner\u2019s guide, you\u2019ll learn what smart contracts are, how they work, and why they matter in crypto.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_a_Smart_Contract\"><\/span>What is a Smart Contract?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img decoding=\"async\" class=\"alignnone wp-image-16872 size-full lazyload\" data-src=\"https:\/\/blog.prestmit.io\/wp-content\/uploads\/2022\/01\/18th-2-1.webp\" alt=\"Smart contracts in cryptocurrency \" width=\"1200\" height=\"630\" data-srcset=\"https:\/\/blog.prestmit.io\/wp-content\/uploads\/2022\/01\/18th-2-1.webp 1200w, https:\/\/blog.prestmit.io\/wp-content\/uploads\/2022\/01\/18th-2-1-1024x538.webp 1024w, https:\/\/blog.prestmit.io\/wp-content\/uploads\/2022\/01\/18th-2-1-150x79.webp 150w, https:\/\/blog.prestmit.io\/wp-content\/uploads\/2022\/01\/18th-2-1-768x403.webp 768w\" data-sizes=\"(max-width: 1200px) 100vw, 1200px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1200px; --smush-placeholder-aspect-ratio: 1200\/630;\" \/><\/p>\n<p>A smart contract is a digital contract or agreement stored on a <a href=\"https:\/\/prestmit.io\/blog\/5-things-you-need-to-about-blockchains\/\">blockchain<\/a> and can take action after fulfilling predetermined conditions. Smart contracts can be viewed as digital logic or rules for enforcing an agreement or contract without human interference or assistance.<\/p>\n<p>In other words, a smart contract can be viewed as \u201cif condition X is met, then action Y is taken.\u201d The blockchain ensures this condition is met and takes the required action without the assistance of intermediaries such as banks or lawyers.<\/p>\n<p>Smart contracts can be viewed as the backbone of tokens, decentralized exchanges, <a href=\"https:\/\/prestmit.io\/blog\/best-crypto-lending-sites-in-2022\">lending platforms<\/a>, NFTs, and other applications.<\/p>\n<p>They are also the operational engine behind <a href=\"https:\/\/prestmit.io\/blog\/what-is-defi\">DeFi (decentralized finance)<\/a> systems, ensuring secure, trustless execution of financial activities. By embedding rules directly into code, they allow value, ownership, and operational logic to reside entirely on-chain.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Smart_Contracts_Work\"><\/span>How Smart Contracts Work<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Smart contracts operate on <a href=\"https:\/\/prestmit.io\/blog\/4-types-of-blockchain-network\">blockchain networks<\/a> with programmable logic. They are created using programming languages like Solidity for <a href=\"https:\/\/prestmit.io\/blog\/ethereum-101\">Ethereum<\/a> or Rust for Solana. Once deployed, these contracts are immutable unless explicitly designed with upgrade mechanisms, ensuring trust and security.<\/p>\n<p>In the deployment of smart contracts, the developer will write the contract, which will then be compiled into bytecode. After the contract has been deployed in the form of a transaction, it will then be given an address.<\/p>\n<p>A user will interact with the contract using a smart contract call, which will be in the form of a transaction sent to the contract address. It will then be executed on the blockchain.<\/p>\n<p>Smart contracts will execute exactly as programmed with the blockchain validation, with no external factors affecting the contract. They will execute exactly as programmed, with the blockchain validation ensuring the contract works exactly as it should.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Key_Features_of_Smart_Contracts\"><\/span>Key Features of Smart Contracts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Smart contracts are the key innovation in blockchain technology. They make digital contracts possible.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Automation\"><\/span><span style=\"font-weight: 400;\">1. Automation<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The contracts operate automatically once the terms are met. The contracts do not require approval from any third parties. The automation of smart contracts makes them reliable and efficient in operation.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Immutability\"><\/span><span style=\"font-weight: 400;\">2. Immutability<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The code of smart contracts cannot be easily changed after they are created. The code is immutable. The immutability of smart contracts makes them reliable in operation because the terms of the contracts can never be changed.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Transparency\"><\/span><span style=\"font-weight: 400;\">3. Transparency<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The code of smart contracts is publicly visible in <a href=\"https:\/\/prestmit.io\/blog\/list-of-7-top-blockchain-explorers\">blockchain explorers<\/a>. Anyone can access the code before agreeing with another party. The transparency of smart contracts helps in building trust between parties.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_Decentralization\"><\/span><span style=\"font-weight: 400;\">4. Decentralization<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Smart contracts operate in many nodes instead of one server. The operation of smart contracts in many nodes makes them reliable in operation because there is no risk of centralization.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_Deterministic_Logic\"><\/span><span style=\"font-weight: 400;\">5. Deterministic Logic<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The result of smart contracts is always certain. The result of smart contracts is always deterministic because the result of smart contracts is always certain given any term.<\/p>\n<p>These attributes above make smart contracts the main innovation behind blockchain technology.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Smart_Contracts_Are_Used_in_Crypto\"><\/span>How Smart Contracts Are Used in Crypto<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Smart contracts are used to build layers of operations in a blockchain.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Decentralized_Finance_DeFi_Protocols\"><\/span>1. Decentralized Finance (DeFi) Protocols<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Decentralized Finance is enabled through the use of smart contracts. With smart contracts, users can borrow, lend, and trade, among other activities.<\/p>\n<p>For\u00a0 instance, when funds are deposited in a platform like Aave,\u00a0a contract is created that locks collateral and pays interest, among other activities. All activities in decentralized finance are carried out through smart contracts, ensuring transparency and trust in the system.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Token_Creation_and_Digital_Assets\"><\/span>2. Token Creation and Digital Assets<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Smart contracts are used to create digital assets, including cryptocurrencies, NFTs, and governance tokens. When creating a new cryptocurrency, a standard is set, either <a href=\"https:\/\/prestmit.io\/blog\/the-differences-between-trc20-and-erc20-usdt\">ERC-20<\/a> or ERC-721, which is used to create a new token. This is a process that is carried out automatically, ensuring that ownership is accurately managed and verifiable, creating digital ownership.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Governance_and_DAOs\"><\/span>3. Governance and DAOs<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Smart contracts are used to create DAOs, which enable governance. When a governance proposal is passed, a contract is automatically executed, ensuring that governance is carried out accurately and transparently.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Popular_Blockchains_Supporting_Smart_Contracts\"><\/span>Popular Blockchains Supporting Smart Contracts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"1_Ethereum\"><\/span>1.
