The utility tool for Solana Validators

solv is an open-source tool designed to simplify the setup and operation of Solana validators and RPC nodes.

Documentation: https://solv.epics.dev/

• Linux Ubuntu 20.04 LTS
• Linux Ubuntu 22.04 LTS

Login in to your Validator server by ssh and run the following command.

$ bash -c "$(curl -sSfL "https://storage.googleapis.com/epics-bucket/resource/solv/v4.1.16/install")"
$ cd ~ && source ~/.profile
$ solv setup

Then, select the type of node you want to target.

• TESTNET_VALIDATOR
• MAINNET_VALIDATOR
• RPC_NODE

Then

After startup, the snapshot download will start automatically. The Solana validator will start 🎊

If your node does not start, you can try the following command.

$ solv restart --rm

This will remove the snapshot and restart the Solana Validator from the new snapshot. If snapshot download freezes, you can try Ctrl + C. Then setup will continue.

🌱 No more SSH login required for Solana/solv version update 🌱

Introducing the new solv MEV mode that takes care of Solana/solv version updates seamlessly. Now, you can update the Solana/solv version without the need for SSH login to the server.

Key Features:

• Automated Updates: solv MEV mode will automatically update the Solana/solv version for you, ensuring you are always running the latest version without manual intervention.

• Monitoring: solv MEV mode will monitor the health status of your validator and balance, sending notifications to Discord.

• Automated Reward Harvesting: This mode will harvest your rewards to your authority account right before the epoch ends, optimizing your yield.

• Automated Staking: After harvesting, rewards will be converted from SOL to LST(Liquid Staking Token - elSOL) and sent to your desired account.

• Enhanced Security: By keeping the balance of SOL in your validator node low and converting rewards to LST, this strategy mitigates the risk of large-scale SOL withdrawals, ensuring high yield maintenance.

solv MEV Mode is a feature designed to automate the maintenance of your Solana validator by regularly checking and updating the Solana/solv status and version.

• solv epochTimer: This function will be set as a cron job to automatically monitor the health status of your validator and perform updates as needed.

• Automatic Restarts: If necessary, solv epochTimer will restart the validator to ensure optimal performance.

epochTimer will monitor the following aspects of your validator:

• Send a notification if the balance is less than 0.5 SOL.

• Send a notification if the validator is not voting or is delinquent.

• Send a notification if the Solana/solv version is not up-to-date.
• Update the Solana/solv version automatically.
• Restart validator if it is required.
• Send a notification after the Solana/solv version update.

• Withdraw the rewards from vote account to the authority account.
• Calculate the balance needed for the next epoch.
• Transfer the balance from the validator account to the authority account.
• Convert SOL to LST(Liquid Staking Token) and send it to the harvest account.

By implementing solv MEV mode, you can maintain high security, ensure optimal performance, and enjoy the convenience of automated updates and reward management.
