Built a feature

Released NFT support for the Hana Wallet (https://hanawallet.io) browser extension 🎉 you can now view and transfer your ICON, Ethereum and Binance Smart Chain NFTs. This has been built and tested internally for a few months, but we've been waiting for some critical changes to the Craft (https://craft.network) API to improve ICON NFT support.


The biggest piece of work here was building an aggregation layer into our Hana API, so that we can get NFT metadata as well as ownership and transfer information from multiple chains. We store the metadata and cache the images on Cloudinary (https://cloudinary.com) so that we can fetch them on-demand at suitable sizes. There are scripts on the API which periodically check for changes to NFT metadata and images.
