Deep Integration of Bifrost and Zenlink products, first liquidity derivative mining for slot auctions on the horizon

We are pleased to announce that Zenlink SlotVault, the “PLO as Mining” class of machine gun pools created by Zenlink, will be deeply integrated with SALP, Bifrost’s slot auction derivative solution, to provide the first liquid derivative for slot auctions mining product. By staking KSM/DOT on the Zenlink SlotVault DApp to participate in the Bifrost crowdsale, users will not only receive a variety of benefits including parachain tokens, but also unlock the liquidity of the KSM/DOT locked in the auction, maximising the benefits of the crowdloan!


SlotVault is a machine gun pool product created by Zenlink in conjunction with the Polkadot Slot Auction. The platform aggregates many parachain auction projects and other polkadot ecological projects, encourages cooperation between projects, forms a crowd lending support system, thus increasing the success rate of parachain slot auctions, and provides multiple token incentives for users to participate in the PLO process, bringing a “PLO as mining” experience. It also provides multiple token incentives for users to participate in PLO, bringing a “PLO is mining” experience.


The SALP protocol is the first slot bidding derivative protocol proposed by Bifrost, with the SALP protocol, Bifrost will unlock the liquidity of locked KSM/DOT in slot bidding by generating derivatives vsToken (vsKSM/vsDOT) and vsBond. SALP unlocks the liquidity of KSM/DOT in slot bidding by The Polkadot Cross-Chain Protocol XCMP creates derivatives completely decentrally, allowing users to participate in crowd-lending with security, trustless barriers, and unlocked liquidity, thus reducing opportunity costs.

SlotVault + SALP

Specifically, Zenlink SlotVault will add an entry point for all parachain projects that are live on the platform to participate in their crowdfunding through SALP, which will support all partner project owners in issuing crowdfunding stake derivatives vsKSM+vsBond, providing users with more flexible stake options, once Bifrost becomes an official parachain.

At the same time, the Zenlink DEX Module will be deployed on the Bifrost parachain and the vKSM/KSM trading pairs will be available on Zenlink as soon as possible, making it easy for users to complete the Contribute-Swap process in one stop.

The combination of Zenlink SlotVault and Bifrost SALP will also give birth to an innovative mining method that combines PLO mining with SALP derivatives mining, providing multiple benefits to users.
