Hello. Can we add Erc-20 token as asset to Nxt blockchain?
You could create an asset on the nxt blockchain which represent an Ethereum ERC-20 token, this would be considered a "pegged" or "wrapped" token.
How can I do that? Can you explain in detail?
Check Bitswifts wrapped assets for example:
https://bitswift.cash/explorer/market
Each is an asset registered on the Ignis blockchain. They have built a gateway which allows these assets to be imported and exported to their original chain in a 1:1 manner. You would have to build your own gateway that accomplished the same for the erc-20 token. In this manner you could have wrapped erc-20 on nxt. You can define the erc-20 token using the asset properties on nxt: Asset Properties - Asset Properties
Thank you Asmurf
