What can your token be used for?
Extra Finance uses two tokens to manage its utility and governance:
`$EXTRA` — ERC-20 utility token of the protocol
`$veEXTRA` — ERC-20 governance token of the protocol
`$EXTRA` is used for rewarding liquidity providers through emissions.
`$veEXTRA` is used for governance. Any `$EXTRA` holder can vote-escrow their tokens and receive a `$veEXTRA` in exchange.
Utility
By holding `$veEXTRA`, users can unlock the following benefits and features:
APR rewards, sourced from both protocol fees and `$EXTRA` token incentives.
- The protocol fee comprises various tokens collected into the treasury and is shared once per epoch. It is used to buy back `$EXTRA` tokens from the market and then distribute them to holders of `$veEXTRA` tokens.
- A portion of the `$EXTRA` tokens allocated to the community will also be assigned to `$veEXTRA` token holders, subject to a specific emission plan.
- At the end of each epoch, rewards will be accumulated.
Unlock up to 4x leverage for yield farming pools.
Gain access to lending pools with a high utilization rate. (`$veEXTRA` holders only)
Vote & Governance in the community.
`$veEXTRA`is the voting power in Extra Finance's on-chain governance process. Users could use it to cast for/against community proposals.
