What Is the Role of a Liquidation Bot in a Decentralized Margin Trading Platform?
A liquidation bot is an external, automated agent that monitors the collateral ratio of leveraged positions on a DEX. When a position's margin falls below the maintenance threshold, the bot is incentivized to call the smart contract's liquidation function.
The bot executes the liquidation, typically receiving a small fee as a reward. This decentralized process ensures that risky debt is promptly closed to protect the protocol's solvency.
