On Friday, Harmony (ONE), a fast, open blockchain mainnet running on the Ethereum (ETH) network with two-second transaction finality and fees 1,000 times lower than Ethereum, announced the launch of your Boring Monkey Yacht Club Passport. The Passport allows users to import evidence of their apes into Defi Kingdoms, a play-and-win game built on the Harmony blockchain with over 120,000 monthly active users. During its initial stages, ape holders will be able to validate and display their in-game assets across multiple blockchains when they connect their Metamask wallet to Defi Kingdoms.
The infancy of cross-chain technology means funds could be at risk when connected across chains, as the biggest decentralized finance hack so far this year has shown. However, As its developers explain, Harmony Passport does not move assets; instead, it proves ownership of assets across multiple blockchains, guaranteeing their authenticity at all times. Its cross-chain bridge, Horizon, currently supports interoperability between ONE, Ethereum, BNB Chain, and three other blockchains.
Leo Chen, a member of the Harmony team, explained:
“We wanted to give all NFT holders more utility and options to display their NFTs and participate in the metaverse. Bored Ape Yacht Club holders are the first choice. Cross-chain identity creates a safe and easy way to do so without put your assets at risk.
In a similar move, Twitter launched its NFT campaign last month, allowing its paying subscribers to display their NFT possessions as profile photos.. However, the technical functionalities of the feature are in the testing phase, with only Ethereum-based NFTs eligible and no support for cross-chain functionalities.
