solana/stake-monitor

Overview

solana-stake-monitor is a utility that scans all transactions to ensure that stake accounts remain in compliance with the following rules:

1. The stake account must be created after genesis
2. The "compliant balance" of a stake account is set upon stake account initialization, system transfers of additional funds into a compliant stake account are excluded from the "compliant balance"
3. The stake account cannot have a lockup or custodian
4. Withdrawing funds from the stake account trigger non-compliance
5. Stake accounts split from a compliant stake account remain compliant, and the "compliant balance" is adjusted accordingly for the original stake account

In terms of solana command-line subcommands:

• create-stake-account: Creates a compliant stake account provided the --lockup-date, --lockup-epoch, or --custodian options are not specified
• delegate-stake / deactivate-stake / stake-authorize / split-stake: These commands do not affect compliance
• withdraw-stake / stake-set-lockup: These commands will cause non-compliance
• transfer: Any additional funds transferred after create-stake-account are excluded from the "compliant balance"

System accounts can also be manually enrolled with the solana-stake-monitor enroll subcommand. An enrolled system account must always maintain a balance greater than the balance it had at enrollment minus 1 SOL.
