Pieverse, a chain payment protocol, has partnered with NFT project Moonbirds to introduce a co-branded soulbound token (SBT) for airdrop rewards, marking Moonbirds' debut on the BNB Chain. The SBT is available for claim on the Ethereum network for Pieverse users who completed pieUSD transactions before 8:50 GMT on November 13, as well as for holders of Moonbirds, Mythics, and Oddities NFTs, with one SBT per NFT. This collaboration aims to integrate Moonbirds' NFT ecosystem with Pieverse's x402b protocol-driven smart agent payment track on the BNB Chain, enhancing the utility and interoperability of NFTs across different blockchain ecosystems.
