At the time of writing, the IOV Name Service on Cosmos SDK is only testnet.
On the testnet, we have set up a faucet so that anyone can get tokens to play with.
You need to replace the address after
address=with your address on testnet, and you will be credited 1000 IOV (or more exactly 1 000 000 000 uvoi).
There is a finite amount of tokens in the faucet, please draw from it only for your testing or ask for people who have tokens to send some to you!
