Kava Network Information

Empowering the next wave of developers in creating the next generation of blockchain technology, the Kava Network is a Layer-1 blockchain that combines the speed and scalability of the Cosmos SDK with the developer support of Ethereum through its unique co-chain architecture. Kava focuses on interoperability to bring together the Ethereum and Cosmos Co-Chain ecosystems, while optimizing the scalability to enable less friction for the flow of users, assets, and projects alike—as it is powered by the Tendermint Core consensus engine.

KAVA is the governance token of the Kava Network and can also be staked by validators or delegated to validator nodes. Stakers and delegators earn a portion of the network's fees as a reward for securing the network and also have voting rights in network governance proposals.

The Kava protocol facilitates a peer-to-peer lending protocol where users can lock their funds in smart contracts. Then those contracts mint new USDX tokens that users can take as a loan based on collateral. Much like other blockchains, Kava’s native token, KAVA, is utilized to facilitate governance voting to help guide the network upgrades and enhancements, including parameters related to collateralized debt positioning system. The token is used additionally to help maintain the network’s security by allowing holders to validate blocks and stake on various applications.

With a function to serve as a reserve, the network will mint new KAVA to utilize in the purchase of USDX if USDX becomes over collateralized, allowing Kava to ensure its stablecoin retains its value.

Celer’s cross-chain bridge, cBridge, supports the cross-chain bridging of KAVA between multiple chains with the fastest speeds, lowest costs, and most secure transactions available. The full name of this asset is Kava token and the ticker of this asset is KAVA.

Astar Network Information

Rebranding itself from Plasma to Astar Network in 2021 with a greater vision to support its ecosystem, Astar Network is a multiple blockchain dApp hub that offers dApps staking, L2 solutions, and a cross virtual machine that supports EVMs.

Astar Network is composed of several major components working together including Polkadot, to facilitate cross chain communication. Astar is considered the Polkadot version of Shiden Network for Kusama. Parachains are also used to connect independent blockchains to the Polkadot ecosystem. Astar also supports crowd loans to help fundraise for a parachain slot within the Polkadot ecosystem.

ASTR token is the native and governance token of the Astar Network. ASTR tokens are used for staking directly on Astar dApps.

Similar to many popular blockchains, ASTR is the native token for the Astar Network for transaction on-chain fees. The ASTR token has 3 other utilities including (1). Facilitating governance activities like voting and referenda, (2). Staking on different decentralized applications and the network itself, while earning ASTR tokens as rewards, (3) layer 2 networks and applications can deposit ASTR on their respective Layer 1s in creating layer 2 applications that can support omnichain general message and liquidity passing.

Celer’s cross-chain bridge, cBridge, supports the cross-chain bridging of ASTR between multiple chains with the fastest speeds, lowest costs, and most secure transactions available. The full name of this asset is ASTAR and the ticker of this asset is ASTR.

What is a Blockchain/Crypto Bridge?

Blockchain or Crypto bridges work just like the real thing, but instead of connecting physical places together, they are used to connect digital ecosystems together. These bridges can pass both information and assets between the bridged blockchains. We call this a cross-chain transfer.

As an example, if you have a need to use a token on Astar Network, and you have that token on Kava Network and not on Astar Network, you could either deposit more of that token specifically on Astar Network, or you could find a Astar bridge that will bridge that from Kava Network to Astar Network so you do not have to spend more to get additional tokens just because it is on Astar.

There are also different types of bridging in terms of how the cross-chain transfer is done from a technical standpoint. There is liquidity-based bridging where there are liquidity pools of an asset on both the source and destination blockchains. There is also canonical-based bridging where an asset is locked on the source chain and a new asset that represents that locked asset is created on the destination chain.

Bridging and cross-chain transfers are not limited to just normal assets or fungible tokens either. Bridges can transfer and move non-fungible tokens (NFTs) between chains as well. cBridge supports 2 main models when it comes to NFT bridging, pegged NFT bridging and multi-chain native (MCN) NFT bridging. Pegged NFT bridging is similar to the canonical-based bridging mentioned above. The NFT is locked on the source chain and a new NFT that represents that locked NFT is created, or minted, on the destination chain. In the MCN NFT bridging model, however, a MCN NFT does not have the notion of “origin chain” or "original NFT". When transferring an MCN NFT from chain A to chain B, the only pattern is "Burn-and-Mint" so that there is always only one NFT across all of the chains.

Then there are the different levels of “trust” you can have in a crypto bridge. The two main types are trusted and trustless bridges. Trusted bridges depend on a central system or entity and require you to put your trust in them if you wish to use their bridge. Trustless bridges, like our own cBridge, are completely controlled by and run on automated smart contracts and algorithms that have the same security and stability as the blockchain itself.

Things start to get a more complex from there so if you are interested in learning more about the different types of bridges and the tech behind them, you can read through our documents here:

What are the Benefits of Using a Blockchain/Crypto Bridge?

There are many reasons you may want to use a bridge to do a cross-chain transfer between different blockchains:

Lower transaction fees

You can take advantage of platforms with lower transaction fees and higher speeds when compared to more congested chains, like Ethereum Mainnet. Especially when exploring different decentralized applications (dApps). You can look at alternative chains, like BNB Chain, and bridge whatever asset you wish to bridge, from Ethereum to BNB Chain. You can then get some of that chain’s utility token and will be able to enjoy the lower transaction fees and higher speeds afforded to chains like BNB Chain.

Take advantage of other dapps and opportunities on different blockchains

If you’ve been providing liquidity for lending out a certain token on Kava Network, but see that the interest rate for lending that token on Astar Network is significantly higher; you can use a cross-chain transfer to move your tokens from Kava Network to Astar Network in order to take advantage of that higher interest rate.

Explore other blockchain ecosystems

The Web3 world is growing fast and you now have more options than ever before when it comes to different blockchains and dApps on those chains. There are many different compelling reasons why developers are building on the chains they are and with all of this diversity it makes it difficult to select a chain to invest in. Bridges and cross-chain transfers help solve this issue. By giving you the ability to bridge assets like ETH, USDT, USDC, and BTC to different chains, this opens up your options when it comes to being able to explore alternate L1 chains and the native dapps and services that they provide.
