Introducing Gliaswap!
A cross-chain DEX demo showing the flexibility of CKB has arrived!
Sparkling
We saw an exciting CKB demo this week, Gliaswap, a cross-chain DEX that is designed for user-friendliness, has been released on the Aggron testnet and open-sourced on Github. Gliaswap is a demonstration of Interoperability 2.0: it inherits Portal Wallet's integration with Ethereum wallets such as Metamask and even includes the flexibility of Wallet Connect. Cross-chain transactions with Ethereum are powered by the newly announced Force Bridge.
Let's take a look at the details of Gliaswap:
1. Gliaswap is a hybrid DEX that allows for order placement through both Automated Market Making and an Order Book. This flexibility is implemented through the unique characteristics of CKB's cell model. Alice can lock funds on Gliaswap, with an unlock condition that requires someone else to provide the desired asset in exchange at the specified price. This means Alice's locked assets can technically be taken by anyone, but only if they provide what Alice wants in exchange!
2. Gliaswap utilizes pw core, which means blockchain users can use their existing wallets and addresses to complete transactions on Gliaswap. We are excited by the adoption possibilities this capability brings to Nervos. This also means that a user can complete a cross-chain transaction on supported chains (Ethereum<>CKB) inside a single UI and using a single wallet. Just a reminder that any dApp built on CKB can leverage pw core!
3. Cross-chain transactions through Force Bridge: In addition to supporting CKB-native assets, Gliaswap also supports cross-chain transactions with Ethereum through the Force Bridge. Other dApps can also support cross-chain transactions leveraging Force Bridge functionality. Force Bridge builds light client verification into Ethereum and CKB to verify block header information from the other chain and verify transaction inclusion. The Force Bridge roadmap targets a fully decentralized bridge through two-way SPV verification, read more here!
4. Gliaswap is a demo product based on the Glia protocol. Any product based on the Glia protocol can share liquidity, which opens up possibilities for new application developers! This creates the concept of the liquidity of the network, instead of a particular dApp on the network. If DEX A and DEX B are based on the Glia protocol, the liquidity across their pools can be shared. Recently on Ethereum we can see the value of synergy in the integrations of Yearn, Sushiswap, Cover, etc. and the excitement this can bring to an ecosystem.
RFC
Nervos applies the RFC (Request for Comment) process for implementing every building block of the protocol. There were 27 Previous RFCs, which can be found here.
