Bifrost’s Slot Auction Liquidity Protocol has launched to release users’ KSM/DOT liquidity locked in a crowdloan by generating derivatives. SALP will greatly increase the capital utilization of the crowdloan and attract more participants who do not want to lose opportunity costs to support the parachain slot auction. For users, SALP provides the opportunity to participate in a crowdloan without a DOT/KSM lock-up. For parachain projects, SALP increases the probability of successful bidding. In terms of the Polkadot or Kusama ecosystems, SALP will increase the amount of slot auction bonding, allowing DOT/KSM to derive more creative functions.
Bifrost’s SALP will generate vsDOT/vsKSM and vsBond, two derivatives. Among them, vsDOT/vsKSM is a completely fungible token, while vsBond will differ on parachains. For example, parachain 1 and parachain 2 will generate different vsBond-1 and vsBond-2. VsBond-1 itself is fungible, vsBond-2 is also fungible, but vsBond-1 and vsBond-2 are nonfungible. In addition to different parachains participating in the auction, vsBond will be different. The bidding behavior of the same parachain in different periods will also generate different vsBond, which will be explained in more detail later.
Nonfungible factors such as different parachain lease periods, different redemption periods and inconsistent parachain reward strategies have led to the inability to achieve complete fungibility of derivatives, and nonfungibility is an obstacle to liquidity. In contrast, fungible derivatives will put liquidity together from different parachain crowdloans, forming an objective liquidity advantage. Therefore, Bifrost starts with the token attributes in a crowdloan, decouples its attributes to utility and equity, and designs two derivatives: vsToken (Voucher Slot Token) and vsBond (Voucher Slot Token).
– SALP Derivatives Workflow
The former is a fungible token, which represents a voucher of a user’s contribution to a parachain auction. The voucher can be traded at any time or cooperated with vsBond for a one-to-one redemption.
The latter is a token representing the auction reward and lease period of different parachains, which smooths out the problem of different reward strategies between parachains. Meanwhile, vsBond can execute transactions through Bifrost’s built-in vsBond market without having to consider liquidity issues.
Bifrost hopes to distinguish between a token’s utility value and equity in the simplest way through vsToken and vsBond. At the same time, vsToken will have strong liquidity as a contribution derivative.
The mechanisms of vsToken and vsBond
VsBond represents the specific parachain and its successful lease period. Therefore, the full name of vsBond is vsBond+Parachain Project Name+Retirement Date, for example: vsBond-Bifrost-2022–06–01.
VsBond has two main attributes:
- Contribution Reward: VsBond can be transferred to the corresponding parachain through XCMP and then only the address holding vsBond needs to be identified as a contributor.
- Combined with vsToken, vsToken can be redeemed one-to-one after slot retirement. Therefore, vsBond can be regarded as a special product that contains contribution rewards and a one-to-one redemption. As an equity certificate, vsBond does not require high-liquidity transactions and can be sold through a buy-in-price form of pending orders in the Bifrost vsBond market without creating liquidity pools.

VsToken: A fungible token that releases contribution liquidity
The function of vsToken enables contributors to sell the vsToken in exchange for the original token before slot retirement to achieve the purpose of releasing liquidity.
Unlike vsBond, vsToken is not tied to specific parachains and slots. To this end, Bifrost designed two exchange pools to achieve the fungibility of vsToken: 1-to-1 peg pool and Bancor pool (1: x, x ≤ 1).

Potential cooperation projects
In the future, after Bifrost officially launches a parachain, SALP will be presented in a productized manner. Projects participating in the parachain slot auction can be configured with SALP to complete the creation of slot liquidity derivatives, and users can utilize Bifrost’s decentralized application. SALP easily participates in the parachain crowdloan of the cooperative project. All votes will be automatically transferred to the crowdloan address of the corresponding parachain through the Bifrost SALP Module to participate in the auction. At present, SALP has also reached a potential cooperative relationship with a number of projects that require parachain auctions. In addition to trading and using a decentralized exchange in Bifrost vTokenSwap and Polkadot/Kusama ecosystems, vsToken will also expand the liquidity scheme in centralized exchanges. With the launch of Bifrost’s parachain, the minting scale and liquidity of vsToken will be further gained to improve, and the SALP program will also be open for use in other projects.
The Bifrost SALP implementation plan is an innovative derivative product designed by the team after in-depth investigation of user needs and feasibility analysis and evaluation. On Polkadot, the multi-chain system architecture separates canonicity and validity and establishes a bridge of mutual trust between differentiated consensus systems. Bifrost’s SALP has the same original intentions as Polkadot: Qualitative transaction attributes and differentiated equity attributes are divided into two, which promotes derivatives to obtain sufficient liquidity while lowering the barriers for users to participate. It is believed that SALP will be a creative product in the DeFi ecosystem when Polkadot’s slot auction is officially opened. SALP will also be applied for the first time in Bifrost’s upcoming Kusama parachain slot auction plan.
