Aptos and Wormhole Team up to Bridge NFTs Across Multiple Chains

Aptos has partnered with Wormhole to introduce the capability of bridging NFTs to and from their platform. This new interoperability allows for the transfer of NFTs between multiple supported chains while preserving the NFT's metadata.

Via the Portal bridge, users can currently bridge NFTs from Arbitrum, Aurora, Avalanche, BSC, Celo, Ethereum, Fantom, Karura, Klaytn, Moonbeam, Oasis, Optimsm, Polygon, and Solana to Aptos — or, vice versa. 

When an NFT is transferred out of its origin chain, this is what happens:

1. The NFT gets locked up in the NFT bridge smart contract.
2. An equivalent wrapped NFT is minted into a corresponding collection on the destination chain.

This wrapped NFT has the same name, looks the same as the original one, and behaves exactly like other NFTs on the chain. On EVM chains, the wrapped NFTs are ERC721 tokens, on Solana, they're SPL tokens with Metaplex metadata, and on Aptos, they're instances of the Aptos Token standard.

The new NFT bridge capability unlocks exciting new possibilities for Aptos users, enabling them to explore new use cases for their NFTs.
