It allows users to complete a simple daily blockchain action and mark their presence on a selected EVM chain. Each check-in helps build your streak, grow your activity history, and improve your position on the leaderboard. *** #### What is an onchain check-in? An onchain check-in is a blockchain transaction that confirms your activity for a selected day and network. Instead of only opening an app or clicking a button, you create a real onchain record through your wallet. This makes your activity visible, verifiable, and connected to your wallet address. *** #### Why check in daily? Daily check-ins help you build a stronger onchain profile over time. The more consistent your activity is, the easier it becomes to show that your wallet is active across different EVM chains. This can be useful for users who explore new networks, join ecosystem campaigns, test products, or simply want to maintain regular blockchain activity. *** #### How to complete a check-in To complete your daily check-in, connect your wallet and choose a supported chain. Click Check-in and review the wallet confirmation window. Make sure the selected network is correct, check the gas fee, and confirm the transaction only if everything looks right. After the transaction is confirmed, your check-in will be added to your activity. *** #### Choose the right chain Chainstreak supports many EVM networks, including mainnets and testnets. Mainnet check-ins require real gas fees. Testnet check-ins use test tokens and are often better for learning, testing, and exploring new ecosystems. Always make sure your wallet is connected to the same chain you selected inside Chainstreak. *** #### What is a streak? A streak shows your repeated activity over time. When you check in regularly, your streak grows. This helps show consistency and makes your wallet activity stronger inside Chainstreak. Your streak is connected to your onchain actions, not just your account login. *** #### Missed a day? If you miss a day, Chainstreak may give you an option to catch up and restore your streak. Catch-up actions may require a blockchain transaction, depending on the selected chain and current product rules. Always review the wallet popup before confirming. --- # Agent Instructions This documentation is published with GitBook.
