An exploration into StaFi: Staking + Finance

StaFi is a cross-chain liquid staking protocol. It launched in 2020 & aims to solve the contradiction between mainnet security and token liquidity in PoS consensus.

Users maintain network security by staking, while Stafi Validators (SV) and Stafi Special Validators (SSV) are responsible for the safety of the whole protocol and all Staking Contracts, respectively. In return, stakers will receive rTokens (e.g. rDOT, rATOM, rBNB, rSOL, etc.) in a ratio of 1:1 of the staking tokens as the claim to staked tokens and staking rewards.

rTokens can also be traded in the secondary market or be utilised across other protocols to earn yield. At the same time, SVs are rewarded corresponding to the blocks they produced, and SSVs take profit from the multi-signature service and RPC service.

Transaction fees and liquidity fees are collected by the protocol’s treasury, along with any slash forfeits & staking rewards.

Token: $FIS

TVL: ~$30.21m

Market Cap: ~$41.74m

FDV: ~$84.53m

Use Cases

1. Fee Accrual:

  • Gas (will be distributed to validators & Protocol Treasury).
  • Service fee from users.

2. Value Capture: $FIS provides value for the liquidity of rTokens.

3. Supports Staking & Motivation Design:

  • Block Election: A validator obtains its block weight by Staking $FIS or accepting the nomination of staked $FIS, under BABE (block selection) with the GRANDPA (finality) consensus mechanism. Nominators are also required to stake $FIS.
  • Similar to Polkadot, StaFi improves the motivation curve per the Staking ratio of FIS for cyber security and long-term development.


  1. Initial Supply: 100,000,000 $FIS
  2. Token Distribution

  • Circulating Supply: 60,452,000 $FIS (53%), Max Supply: 114,911,733 $FIS
  • Apart from ecosystem growth & community rewards, all tokens have already been vested according to their schedule.

3. Inflation: To motivate SVs and SSVs, an inflationary supply is designed with an annual rate of between 5%-20%. StaFi Protocol will generate new $FIS (through a process called Coinstake) whenever a new block is produced. The formula is as follows

Staked $FIS is ~37.27 million, which accounts for ~32.43% of issuance.

Bullish Fundamentals:

1. Security:

  • Multi-signature Addresses & Secure MPC: Due to SSV’s random selection process of qualified SVs and the periodic replacement of SSVs, users’ staked tokens are sent to an intermediate address managed by multiple SSVs. This method allows for secure signing with private keys and transmission of calculations without the risk of information leakage.
  • Regular rotation and emergency rotation of SSVs

2. Decentralised Validator Network: Unlike some of the projects following PoS, the chance to produce a block is equal to all validators, and each validator is entitled to equal voting power. That is, validators are equally likely to be elected, and there is no direct relevance between reward distribution and the weight of their stake.

Bearish Fundamentals:

  1. Inflationary: At present, the inflation rate is ~15%. Most tokens have undergone full vesting exclusive of inflation, with only 53% in circulation.
  2. 2. Concentrated Token Distribution: The proportion of tokens held by the team & investors is 33.07%.

Closing Remarks

With the rapid growth of liquid staking derivatives, StaFi’s design has earnt it a spot in the top 10. The protocol’s security & decentralised validator network are favourable proponents in the market for LSDs, however, its double-digit inflation rate & concentrated insider holdings have the potential to provide medium-term supply pressure.
