Terra Name Service is to create easy-to-remember names for your Terra address like ‘dokwon.ust’ instead of ‘terra1...whezdr’. You can transfer or exchange assets by simply enter the registered domain name instead of long and unreadable address. TNS also allow to set other data such as NFT, email, Twitter account, etc. You can think of TNS as your on-chain profile. TNS is inspired by ens.domains. We credit the ENS team as the original creator of the idea.
