Step 3:

Input the amount of the token you selected that you would like to transfer from Astar to Avalanche in the “Send:” field. The estimated amount of that asset that is to be bridged to Avalanche will be displayed in the “Receive (estimated)” field.

Step 5:

Wait for your cross-chain bridge transaction to Avalanche Network to complete. You will then receive your bridged tokens on Avalanche.

Please Note: Most cross-chain transfers are completed almost instantaneously, however some may take as long as 20 minutes to complete depending on how much traffic the chain is experiencing.

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.

ASTAR / (ASTR) Current Information

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.

Avalanche Network Information

Avalanche, as a layer one blockchain, is an open programmable smart contracts platform for decentralized applications. Similar to other layer one blockchains, Avalanche supports a wide spectrum of applications related to DeFi, gaming, NFTs, the metaverse, as well as support for stablecoins. Avalanche is composed of three key components that make up the blockchain: (1). The Platform Chain (P-Chain) which coordinates validators and the creation of subnets, (2). the C-Chain for the creation of smart contracts, and (3). the X-Chain for managing and exchanging assets.

As an Ethereum Virtual Machine (EVM) compatible platform, applications that are built using the Ethereum programming language Solidity are also able to be deployed on Avalanche with minimal modifications. This enables developers from one of the largest and widely adopted blockchain communities to build on Avalanche and to deploy custom private or public blockchains as “subnets.”

Avalanche (AVAX) Current Information

AVAX is the native cryptocurrency of Avalanche with 720 million AVAX coins in circulation. AVAX is used to help drive development across the network and can be used for staking and paying for transaction fees. It can also be used in proposing and voting on future network upgrades. In other words, AVAX is the currency of Avalanche and the applications running on it. Whether you want to simply transfer some AVAX between wallets, receive some bridged tokens from another chain like Ethereum Mainnet, or use an application someone had built on Avalanche; anytime you interact with Avalanche you will be required to pay a small fee in AVAX.

Our cross-chain bridge, cBridge, supports the cross-chain bridging of AVAX between multiple chains with the fastest speeds, lowest costs, and most secure transactions available. The full name of this asset is Avalanche and the ticker of this asset is AVAX.

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

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 Astar Network, but see that the interest rate for lending that token on Avalanche Network is significantly higher; you can use a cross-chain transfer to move your tokens from Astar Network to Avalanche 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.
