An entry point to the 1inch Network's tech. The 1inch dApp is a 1 DeFi aggregator, offering access to the liquidity and token swap rates on various DEXes, with features, including partial fill and the ability to find the best swap paths across multiple liquidity sources. Users can optimize trades of DEXs on multiple networks and also with the 1inch DeFi Wallet users can buy crypto with their bank card using our partner fiat gateway providers.

### HyperLiquid
71+
72+
HyperLiquid is a high-performance decentralized exchange focused on perpetual contracts and derivatives trading. While it offers high-speed trading capabilities, it operates as a single trading venue. Yellow Network, in contrast, does not aim to launch a single trading venue but rather provides the infrastructure to build DEXs like HyperLiquid rapidly with lower CAPEX and OPEX through its layer-3 virtual ledger.
73+
74+
### AsterDEX
75+
76+
AsterDEX is another example of a decentralized exchange platform in the Web3 space. Similar to HyperLiquid, Yellow Network's approach differs by providing foundational infrastructure that enables projects like AsterDEX to be built more efficiently. The Yellow Clearnet layer-3 allows builders to create such platforms with reduced capital expenditure and operational costs.

The macroeconomic climate has been defined by inflation and the extension of geopolitical crises. These headwinds have been strongly reflected in the crypto markets. We have also seen the effects of Terra, Celsius, and 3AC’s capitulations impact the market and encourage mass de-risking across all crypto assets.

Yellow Network aims to address this issue by providing **Yellow Clearnet**, a virtual ledger layer-3 infrastructure that uses state channels to connect brokers across blockchains, allowing it to reach tokens locked in isolated networks without cross-chain bridging. The layer-3 is built using state-channel smart contracts (nitrolite - a simplified take on nitro) and clearnode, a golang microservice that acts as the off-chain service for state-channel ledger operations.

The matching throughput of our network averages billions of messages daily, far quicker than any Layer-1 or Layer-2 solution currently available. Our solution is an automated smart clearing protocol, comparable to the function of a clearing house in traditional finance. Yellow Network acts as a mediator between brokers, exchanges, and market makers. It provides users with a protocol that works worldwide. It offers an all-in-one Web3 solution ready for the global retail market, a real-time inter-broker exchange, near-instant off-chain transactions, and efficient on-chain transactions.

Since we started this project, many more Layer-1 and Layer-2 blockchains have appeared, and we are now dealing with hundreds of blockchains. The fragmentation is now acute. There are over 200 notable exchanges and over 6000 cryptocurrencies. Around 100 use their own proprietary blockchain, making it hard to achieve secure interoperability.

2727
Despite the critical nature of blockchain interoperability, cross-chain systems still face several hurdles when transacting assets or data between chains. These difficulties include transaction rate bottlenecks and disparities in trust.
2828

29+
Many projects attempting to solve cross-chain issues have relied on interblockchain communications, copying state from one chain to another. This approach is very problematic as it generates waste on-chain, increases the usage of transactions per chain, is very slow since it requires blockchain confirmation on both ends, and is fairly complex to scale as a generic solution for every blockchain. Different chains may have different security requirements to confirm a state is valid and won't be reverted.
30+
31+
The layer-3 virtual ledger approach remedies these issues by using state-channel smart contracts deployed on every chain and synchronizing the data off-chain using traditional high-speed databases such as Postgres, SQLite, and DHT networks like Kademlia.

The heart of Yellow Network lies in its state channel smart clearing protocol called ClearSync, which operates in a fully decentralized manner. This protocol ensures that the collateral locked within a state channel is governed by a smart contract controlled by the parties involved in the channel. As a result, Yellow Network does not have control over any funds, establishing a non-custodial system for its participants.
1618

In summary, Yellow Network's decentralized architecture, blockchain-agnostic approach, and layer-3 state channel infrastructure work together to revolutionize the financial ecosystem providing participants with enhanced liquidity, faster trading capabilities, and improved secure trading experience.

Yellow Network serves as a clearing and settlement system that facilitates the communication of trading liabilities, updates to states within state channels, and the resolution of state channel challenges. This unique combination of features draws parallels to the SWIFT messaging protocol and ECN direct order matching protocol. While SWIFT and ECN enable brokers to access global financial markets in traditional finance, Yellow Network performs a similar role for digital assets. This clear-cut setup allows Yellow Network to contribute to the separation of powers, duties, and responsibilities by emulating an essential element of the traditional finance stack - the clearing house.
