Opensea Escrow Service
Since HACD is a native NFT on the Hacash mainnet, if you want to trade freely on an Ethereum-based platform, you need to make sure that mainnet's HACD and Ethereum-based platform's HACD correspond at a 1:1 exchange rate.
Hacash.Diamonds is a third-party guarantor aiming to secure your transaction on Opensea, the world's largest Ethereum NFT trading platform.
Please note that only the HACDs guaranteed by Hacash.Diamonds are listed on:
If there are other HACDs on Opensea that are not listed there, please trade with caution.
