Beefy-escrowed tokens, or "beTokens," are a unique feature of Beefy Finance, designed to capitalize on the benefits of escrow tokenomics while enabling users to trade their interests in partner governance tokens. These tokens are essentially wrapper tokens implemented by Beefy to facilitate certain functionalities. In the DeFi context, an escrow mechanism involves users providing their tokens to a third party (like Beefy) to implement functionalities on their behalf. This setup is built around tokenomic designs of the tokens held. Beefy-escrowed tokens (beTokens) are created by Beefy to unlock the benefits of escrow tokenomics, which typically involve staking governance tokens for additional benefits, like earning transaction fees or boosting voting power in governance matters. Beefy Finance currently offers several Beefy-escrowed tokens, each designed to unlock the benefits of specific tokenomic models of partner protocols. Here's a list of the Beefy-escrowed tokens available: beFTM (Beefy-escrowed Fantom): This token offers access to maximized Validator Node rewards on the Fantom network. beFTM is backed 1:1 by FTM and can be staked on Beefy and in farms on major DEXes. beVELO (Beefy-escrowed VELO): beVELO is a Beefy-escrowed version of VELO V1 from Velodrome Finance, backed 1:1 by VELO V1. binSPIRIT: While specific details were not provided in the sources, this token likely involves an escrow mechanism with SPIRIT, the native token of SpiritSwap. beJOE (Beefy-escrowed JOE): This token is likely associated with Trader Joe's JOE token on the Avalanche network, offering similar escrow benefits. beQI: This token is possibly related to the QI token from the Mai Finance (previously Qi Dao) protocol, offering escrowed benefits. beOPX: Details about beOPX were not provided in the sources, but it's likely connected to an Optimism-based protocol, given the naming convention. Each of these tokens is tailored around the different veTokenomic model of Beefy’s partner protocols, offering various features such as withdrawal reserves, supported DEX liquidity, pegged or free-floating pricing, and boosts to associated Beefy vaults. Users can stake these beTokens on Beefy's platform to earn returns, either in more beTokens or in the underlying governance token. beTokens enable users to trade their interests in the partners' governance tokens, despite those tokens being locked or staked. This mechanism rewards long-term holders of a protocol's governance tokens with more voting power, favoring their interests over short-term holders. Users can stake beTokens on Beefy’s platform to earn returns, either in the form of more beTokens or the underlying governance token. The voting power associated with escrowed tokens is often used to direct the economics of the relevant protocol, such as distributing new tokens among liquidity pools. Users can stake their tokens in a Beefy Delegator Vault to get beTokens, which are then used in various ways, including earning rewards and participating in liquidity pools.
