Ethereum smart contracts require external triggers to execute, lacking native scheduling capabilities. This limitation complicates time-dependent actions such as token vesting or recurring payments, as automation cannot be reliably achieved through manual transactions. Decentralized automation tools, specifically Chainlink Automation and Gelato Network, utilize off-chain bot networks to autonomously monitor conditions and trigger contract functions on predefined schedules. This tutorial showcases how to automate token release using both tools, highlighting integration methods, costs, user experience, and key differences, ultimately enhancing the decentralized reliability of smart contract functionalities.
Ethereum smart contracts do not run on a schedule by themselves - there is no native 'cron job' within the EVM.
Smart contracts require an external stimulus to call their functions, challenging time-dependent actions like token vesting without manual intervention.
Chainlink Automation and Gelato Network are decentralized tools that utilize off-chain bot networks to automate function execution, ensuring reliability.
These automation solutions eliminate reliance on centralized cron servers and provide a more decentralized, reliable method for triggering smart contract functions.
