Bifrost developed a Staking Liquidity Protocol called SLP that allows you to get vTokens for operations and delivering liquidity, plus you got staking rewards for your DOT, KSM, EOS or other token that is otherwise locked by the Staking Mechanism. You get reward from the Day 1 of nomination, without locking periods and can change your, for example, vKSM for KSM any time. BNC is the native token of Bifrost. vToken can optimize transactions in multiple scenarios such as DeFi, Dapp, DEX, etc. When vToken is used as a collateral for lending, its staking income can offset part of the interest and realize low-interest borrowing. With vToken you can hedge the risk of locked positions, DeFi & Staking double rewards and leverage Staking and other application scenarios.
Bifrost also developed a Slot Auction Liquidity Protocol to release Liquidity for Crowdloan Contributions, called SALP. It is a protocol to release liquidity from locked DOT/KSM positions in parachain auctions by issuing derivative assets anchored to locked assets. For crowdloan participants, SALP offers the opportunity to participate in Crowdloans without lockup, and to receive the reward of bidding on backed projects without losing staked DOT/KSM liquidity.
The Bifrost Mainnet will migrate from Kusama to Polkadot and there will only be one Bifrost Token BNC.
