Tom N Toms was established in 1999 to popularize Korean coffee and has grown into one of the top coffee brands in the country. The brand has expanded to over 400 branches in 9 different countries worldwide and is expanding market share by targeting both domestic and overseas markets. Tom N Toms recently announced the launch of an NFT aggregator marketplace HEYST, which will be live in mid-December, 2022.

In order to help secure pricing in HEYST, Tom N Tom needs access to fresh asset prices that are supplied directly on-chain in a highly reliable manner. Fair market asset prices should reflect a volume-weighted average from all trading environments. Thus, they needed to make use of an oracle network to fetch aggregated price data off-chain and deliver it on-chain to be consumed by our application.
