Celer Launches Cross-chain NFT Solution on Mainnet

2 min read

We are extremely excited to share that Celer’s cross-chain NFT solution is launching on mainnet! This solution is launching with a new way to create and launch cross-chain native NFTs that can be seamlessly transferred between blockchains as well as an NFT bridge to support the bridging of existing NFTs across all of the Celer supported blockchains. Reach out to us if you are interested in supporting any cross-chain NFT use cases. 

Launching a Cross-chain Native NFT

Built with the Celer Inter-chain Message (Celer IM) Framework, Celer cross-chain NFTs allow developers to issue NFTs with true cross-chain mobility: there is no concept of “source chain” or “wrapped NFT”. Instead, users are able to use or sell their NFTs on any blockchain with one-click cross-chain functionality that is baked into the NFT itself. Therefore, users always maintain true ownership of their NFTs at all times, on all chains. The cross-chain NFT built with Celer IM allows developers to easily add additional functionality on top of bridging support, including other properties that are not normally part of the common NFT standards. In essence, when a cross-chain NFT moves from one chain to another, it will be burnt on the source chain and minted on the destination chain via Celer Network. Cross-chain Native NFTs are ideal for developers launching brand new NFTs and are aiming to build a multi-chain community from the very beginning. 

Bridging Existing NFTs to Multiple Blockchains

For projects and developers that already issued NFTs or NFT marketplaces that want to list NFTs originally issued on other blockchains, Celer’s NFT bridging solution would be able to allow these existing NFTs to be bridged across multiple blockchains freely. This would allow them to be traded and used in various different scenarios. 

The bridge works by creating a “copy” of the original NFT that is a projection of the original NFT on the remote chains. In particular, the bridge process follows the “lock-and-mint”, “burn-and-release”, and “burn-and-mint” patterns.

  • Lock-and-Mint. When an NFT is transferred from the origin chain to a remote chain, the original NFT is first locked in the smart contract on the origin chain. Celer Network passes a message saying that “this NFT is locked on the origin chain” to the remote chain and then a bridged NFT is minted on the remote chain.
  • Burn-and-Release. When an NFT is transferred from the remote chain to the origin chain, the bridged NFT is first burned on the remote chain. Then the original NFT is released on the origin chain with a reverse direction message passed to the origin chain.
  • Burn-and-Mint. When an NFT is transferred from remote chain A to another remote chain B, the bridged NFT is first burned on the remote chain A. Then a new bridged NFT is minted on the remote chain B directed by a message passed by Celer Network. This new bridged NFT may be further transferred back to the origin chain and release the original NFT.
