Reward vaults are smart contracts in which users can stake their Proof of Liquidity (PoL) eligible assets in order to receive $BGT rewards. Reward vaults are the only way in which anyone can earn $BGT rewards, and therefore serve the important function of gating entry into the PoL ecosystem.
Reward vaults are a key piece of infrastructure that allows protocols to leverage PoL, enabling teams to incentivize users' actions in exchange for BGT. A protocol can have multiple reward vaults, each with its own PoL-eligible asset to be staked. For example, BEX can have multiple pools earning BGT, each with its own reward vault and respective PoL-eligible asset.
Staking in a Reward Vault
In order to receive BGT, a user must be staking the PoL-eligible asset in its reward vault. The protocol that deployed the reward vault is able to decide how the user acquires the PoL-eligible asset to stake. The idea is that protocols would leverage this to attract liquidity or stimulate activity, and in return award users with the asset they can stake in their vault.
The user takes some action that results in receiving a PoL-eligible asset, generally referred to as a receipt token.
The user stakes the PoL-eligible asset in the corresponding vault.
The user earns a portion of all the BGT emitted to that vault.
Earning BGT
The amount of $BGT rewards a user earns from a reward vault is a function of:
The user's share of total assets staked in the reward vault
The amount of $BGT rewards emitted to the reward vault
After staking assets in a reward vault, users are free to claim the earned rewards, add to their deposits, or withdraw their assets whenever they wish.
$BGT farming with reward vaults is meant to resemble familiar DeFi actions, providing a low barrier to entry for regular users.
Validators direct some portion of their $BGT emissions to specific reward vaults of their choice.
To understand why validators would choose to emit $BGT to a particular reward vault over another, refer to , which discusses how protocols can influence validator behavior with economic incentives.
