SCF Chain supports digital asset interaction with other public chains through "atomic swaps", which is a peer-to-peer (P2P) transaction system using different blockchains to allow full release of asset liquidity and further enhance user experience.

Zero-knowledge proof is one of the Layer2 capacity expansion schemes supported by SCF double chains, and is also an optional module when implementing parallel chains through Fin-Chain.

Fin-Chain parallel chain supports non-interactive zero-knowledge proof and recursive zero-knowledge proof to ensure the privacy and security of Fin-Chain.

The above two proof methods are the mathematical model and cryptography basis of SCF’s public chain financial infrastructure.

FinSwap
The crypto industry has entered the era of cross-chain, and with the continuous growth of the Web3.0 world's public chain systems, many applications are built on different isolated ecosys-tems. FinSwap is a composable cross-chain liqui-ty aggregation protocol, with contract execution for handling cross chain transactions taking placeon the Fin-Chain with a TPS (Transactions Per Second) as high as 80,000+. Built on its own dual-chain lightning interaction architecture and atomic exchange service, FinSwap aims to address the industry's challenges of decentralized cross-chain liquidity.

FinSBT
FinSBT is the underlying infrastructure of the SCF public chain, collaborating with credit institutions and nodes. It collects and verifies basic informa-tion, credit ratings, and other data to develop smart contracts, enabling functions like user authorization for FinSBT information, institutional verification of FinSBT information, as well as stora-ge and updates of FinSBT information. Utilizing technology like zero-knowledge proofs, it ensures privacy protection, comprehensively covers a financial identity system, and enhances the effi-ciency and security of financial activities.

FUSD
FUSD is the stablecoin issued by the SCF Financial Public Chain, and its operation is maintained through a set of smart contracts for management, issuance, and redemption. The application of FUSD requires sufficient collateral as support. Regular audits of the collateral's value are conducted, and necessary adjustments are made based on market fluctuations. After users collateralize to mint FUSD stablecoins, they can enjoy fivefold benefits, inclu-ding investment returns, loans, stablecoin transac-tion fees, FinPAY payments, and collateral price fluctuations.

FinPay
FinPAY is a decentralized cross-border payment gateway based on the SCF public blockchain. It is currently mainly applied to payment settlements between banking systems collaborating with SCF. It can achieve low-cost and efficient circulation of various national currencies, with the process being secure and anonymous.

FinBill
As the foundational ecosystem of the SCF Financial Public Chain, FinBill aims to achieve six key functio-nalities in a decentralized manner, leveraging the concepts of WEB3.0:

1) Issuance of Financial Bills as NFTs.

2) Trading of Financial Bill NFTs.

3) Providing Liquidity Support.

4) Decentralization.

5) Offering Credit Assessment Services.

6) Delivering Data Query Services.

FinEX
FinEX is the decentralized derivatives exchange on the SCF Financial Public Chain. It offers va-rious derivative trading products, including fu-tures, options, and contracts for difference (CFDs). Users can connect their wallets to FinEX and use their digital assets for trading.

Features

1) Diversity margin ratios.

2) Decentralized trading matching mechanism.

3) Transparent fee structure.

4) Robust risk management.

FinBOX
FinBox is a decentralized instant messaging + con-tent WEB3.0 social platform that leverages block-chain technology, IPFS technology, and encryption technology to achieve social interac-tons. It offers features such as instant messaging, social networking, wallet integration, purchasing, trading, and showcasing NFTs.
