HUMBL (OTCPK:HMBL) on Wednesday has integrated the Polygon (MATIC-USD) sidechain into its non-fungible token platform in an effort to help creators smoothly deliver NFTs to their collectors while reducing gas fees and minting costs. Note that a sidechain is a separate blockchain that's tied to a so-called parent blockchain through a two-way peg. As for the Polygon (MATIC-USD) sidechain, it allows users to conduct faster and less costly transactions on the Ethereum (ETH-USD) blockchain than in the Ether mainchain. “We believe NFTs are still in the very early stages of the Web 3, tokenized economy,” said HUMBL CEO Brian Foote. “NFTs have applications across intellectual property, content distribution and fan interaction and we look forward to helping NFT creators experiment with those channels here at HUMBL.” In March, HUMBL acquired Mexican tech firm lxaya.
