Burner Router

See the code here

The Burner Router allows redirecting the slashed collateral tokens to different addresses, which may be represented by Burners, Treasury contracts, LP lockers, etc.

Full Flow

  1. Setup

    • Before the Vault's creation, deploy a new Burner Router via BurnerRouterFactory with the same collateral address as the Vault will use
    • Deploy the Vault inputting the received BurnerRouter address and IBaseSlasher.BaseParams.isBurnerHook set to true

  2. Update setup

    • Change global receiver, network-specific receivers, operator-network-specific receivers with the configured delay (in case of pending set requests, they are overrided with the new ones)
    • Change delay itself after the delay (in case of pending set requests, they are overrided with the new ones)

  3. Slashing

    • The router is called via onSlash() function
    • It determines the needed address for redirection and saves the redirection amount for it

  4. Trigger transfer

    • Transfers a given account's whole balance from the router to this account
