SFT Chain DApp User Guidance

SFT Protocol
7 min readMay 17, 2024

SFT Chain has established a series of DApp ecosystem applications on the Solana, FEVM, and BSC networks, aiming to build an “SFT Flywheel” circular economy system based on DePIN hardware infrastructure. By optimizing and perfecting this circular system, more value will be captured for SPD within the hardware ecosystem integrated with various public chains.

Before we begin, let’s first introduce what SFT Protocol, rSPD, and SPD are.

What is SFT Protocol?

The SFT Protocol is a core protocol of the SFT Chain network, a cross-chain communication and modular underlying EVM protocol designed specifically for assets that are medium to long-term staked and thus illiquid, such as FIL, DOT, ETH2.0, etc. The SFT Protocol offers a decentralized solution that allows these locked assets to circulate freely. Users stake native blockchain tokens and then mint SFT tokens to solve liquidity issues. SFT holders can engage in various operations within the SFT Protocol, including SFT trading, staking mining/liquidity mining, DeFi lending, DAO governance, NFT minting, public chain node application deployment, and hardware infrastructure utilization. The protocol supports staking and redemption of native tokens, enabling immediate withdrawal, with all operations performed by smart contracts and decentralized validator nodes.
Moreover, the SFT Protocol has also securitized underlying hardware device assets, mapping them to upper-layer protocol revenues, thereby creating a “cross-chain” between blockchain and real-world economic activities. This provides investors with diversified investment channels.

What is rSPD?

rSPD is an early token of SPD, defined as a point system, and can be exchanged on a 1:1 ratio upon the mainnet launch. It allows users to benefit from the growing value of SPD and incentivizes community members to contribute to the project’s long-term development goals.

What is SPD?

SPD is the governance token of SFT Chain in the future (currently not issued), whose main function is to provide community members with the right and opportunity to participate in platform governance. SPD holders can participate in voting on issues such as platform development, parameter adjustments, proposal reviews, etc. Moreover, SPD can be used to incentivize community members to participate in ecosystem construction, such as providing rewards to contributors or supporting the development of specific projects. In summary, the existence of SPD helps promote community development and autonomy, ensuring the sustainable and healthy development of SFT Chain.

Brief Introduction to SFT Chain DApp

1. Stakehttps://sft.network/#/stake

This DApp contract section is built on the FEVM and BSC networks, providing an entry for regular farm and liquidity pool deposits, and displaying on-chain and revenue data of various sections of the DApp.

Fixed farm: In this section, users can complete FIL deposit, SFT minting, and fixed SFT deposit with one click, and earn daily FIL rewards and 10x rSPD farm yield.

Liquidity Pool Deposit (FEVM network only): In this section, users deposit FIL into the Pool liquidity pool and immediately receive rSFT in their wallet addresses, then they can earn from the liquidity pool.

2. Farmshttps://sft.network/#/farm

This DApp contract section is built on the Solana, FEVM, and BSC networks.

SFT Farms is a system where cryptocurrency holders can deposit their funds into a pool together in pursuit of investment returns (a process called “staking”). The process is similar to depositing money in a bank, with the main difference being that in the Farms system your funds are locked up for a period of time.

You can find profitable farms at https://sft.network/#/farm.

2.1 How does SFT Farm work?

Users can stake tokens in the DApp through the “protocol” to get profit.


2.1.1 SFT Farm starts by creating a liquidity pool, which relies on a smart contract that facilitates all investments and borrowing in a specific yield farm

2.1.2 Investors stake their funds by connecting their wallets to the pool;

2.1.3 The smart contract facilitates many processes, including adding liquidity or lending to others;

2.1.4 In the end, investors will receive rewards, which may vary depending on the yield farm. Investors can choose fixed intervals or dates they wish to receive rewards and claim the corresponding rewards on the website.

2.2 What are the rewards for SFT Farms?

Rewards depend on the project you are staking, as detailed below.
Besides, the amount of rewards depends on how much money, time, and effort investors put in. Investors need to have a full understanding of the product to allocate assets reasonably among different products and maximize their returns.

2.2.1 SFT Fixed Deposit
This pool is built on the FEVM and BSC networks. By depositing FIL to mint SFT and staking it in the 6-month term farm, you can begin earning daily rSPD rewards. These rewards are calculated by multiplying your FIL rewards by ten. In other words, if your daily fixed-term staking earns you 5 FIL, you will also receive 50 rSPD rewards.

2.2.2 Stake Raydium-LP
This pool is built on Solana network. By staking Raydium-LP to liquidity pool, a daily reward of 2000rSPD will be shared.

2.2.3 How to Obtain Raydium-LP?

2.2.4 Stake rSFT
This pool is built on FEVM network. By staking FIL to liquidity pool, users will get rSFT. They can then stake this rSFT in the rSPD mining pool to earn twice the FIL earnings from the Pool liquidity pool.
It is clear that the overall returns from a 6-month fixed-term stake will exceed rSFT staking.

2.2.5 Stake LP
This pool is built on FEVM network. Users can acquire FIL+rSPD in a 1:1 ratio by depositing into the Pool liquidity pool. They will instantly receive FIL-rSPD-LP in their wallet addresses. This FIL-rSPD-LP can then be staked in the SMH/ALEO mining pool, with users receiving either SMH or ALEO as a reward.

2.2.6 Stake Sushi-LP
This pool is built on FEVM network. By staking Sushi-LP to liquidity pool, a daily mining bonus of 2000rSPD will be shared(Currently migrated to Solana Network).

3. Poolhttps://sft.network/#/pool

This DApp contract section is built on the FEVM network and plays a unique functional role in “SFT Flywheel” economic system.

Lending: Users deposit FIL into Pool, providing temporary funding for users with fixed-term staking for their financial needs.

Bridging funds: When the utilization rate of Pool is less than 95%, facing FIL redemption needs on the SFT fixed farm chain, Pool acts as a bridging fund, temporarily allocating FIL to the redemption pool to meet the redemption needs of the fixed farm, and obtain SFT and revenue.

Revenue distribution: Users providing FIL to the liquidity pool will receive FIL revenue in real-time, which comes from the staked rSFT.

Reserve fund: When building LP, users will provide FIL: rSPD = 1:1, and the revenue generated by LP staking will be deposited into the Pool.

4. Launchpadhttps://sft.network/#/Launchpad

Launch: Online public chain mainnet;

DApp: Built on FEVM (discontinued), Solana network;

Features: All participating rSPD being burned, and tokens will got at 15% discount on DEX price;

Components: Rewards and BID;

Launchpad Rewards: By staking rSPD (up to three times per day), users can get tokens with a 15% discount on the exchange price, such as SMH;


  1. Settlement time: Every 8 hours.
  2. Discount: 15%.
  3. Participants will divide rewards and deduct rSPD based on their contribution proportion, with deducted rSPD being destroyed.
  4. Participants can stake rSPD repeatedly. Any remaining rSPD after deduction will be accumulated for the next period, allowing continuous participation in offerings, and can be redeemed at any time.

Launchpad Auction

Users have 3 bidding opportunities per day to obtain bids by using rSPD. rSPD will be deducted and destroyed from the wallet address of successful bidders.

Bid: Public chain projects that are online but not on major centralized exchanges.

5. DePINhttps://sft.network/#/DePIN

Launch: Early testnet of public chain projects;

DApp: Built on FEVM (discontinued), Solana network;

Features: Users use rSPD to participate in the early test network of the public chain project. After the project is launched on the mainnet, users will get excess reward earnings, then all the participating rSPD will be burnt.

6. Bridgehttps://sft.network/#/bridge

Chain crossing: Users can transfer SFT, rSPD from one chain to another

DApp: Built on Solana, FEVM, BSC networks.

Features: 5 rSPD will be destroyed as transaction fees for rSPD crossing from SOL to other chains, or vice versa. There will be no transaction fees for SFT crossing, or rSPD crossing between FEVM and BSC networks.

7. Lendhttps://sft.network/#/lend

Function: Provide temporary funding for users with fixed-term staking for their financial needs.

DApp: Built on FEVM network

Users can only borrow tokens with 60% of the staking amount(if you staked 100 SFT in Fixed farm, you can borrow no more than 60 SFT);
Users will not be charged additional interest;
The earnings of the borrowed portion will belong to Pool, instead of the borrower(if you staked 100 SFT in Fixed farm, you borrowed 60 SFT, you will only receive earnings from the rest 40 SFT before repayment)
