Get test coins

First: a testnet wallet

Install Nautilus’s testnet build and make a new wallet just for testing. Try the testnet prototype has the steps. Never use a wallet that holds mainnet funds, and never type a mainnet seed phrase into a testnet wallet.

Testnet ERG

Testnet ERG is the coin of Ergo’s public testnet. It pays for transactions there, and for the ERG side of a trade or of liquidity.

How to get it: use the Test coins tab in Kadia DEX, with Testnet selected. It sends test ERG and tUSE to your testnet address, which starts with 3. If the faucet is empty or paused, ask in the tester channel your invitation came from.
How much: a few ERG is enough to try swaps and liquidity. Every order also carries a small execution-fee cap and a miner fee, and payouts carry a rent reserve that stays yours.

Test USE

Test USE stands in for USE on testnet. It’s a token minted for Kadia’s testnet, with the ticker tUSE and 3 decimals. It isn’t USE, and it has no value.

How to get it: swap testnet ERG for it in Kadia DEX, on the ERG / tUSE market. You can also ask in the tester channel.
Check the token id, never the name. Anyone can mint a token called “Test USE” or “tUSE”. The real one is 71ef749a44a1e92c7b9e6e7da9e4b73e3e0ab4773de482c9af1f1b201df27464. The testnet DEX record lists the market’s other ids.

Seeing your balance

Nautilus shows your testnet ERG and tokens. Kadia’s explorer reads mainnet only for now, so it won’t show testnet balances.

Stay safe

Kadia never asks for your seed phrase, private keys or wallet password. Nobody from Kadia will.
Test coins can’t be swapped for real ERG or real USE, and nobody can sell them to you. If someone offers, it’s a scam.
