Test assets#
| Asset | Type | Decimals | Use |
|---|---|---|---|
| tZROAR | Native currency | 18 | Gas and native transfers |
| tZUSD (Zroarus Test USD) | ERC-20 with EIP-2612 permit | 6 | Stablecoin-style testing |
| WtZROAR (Wrapped tZROAR) | ERC-20 (WETH9-style) | 18 | Pools and contracts that need an ERC-20 |
Token contract addresses are listed on the explorer's tokens page(opens in a new tab). Always read decimals() on-chain: tZUSD uses 6 decimals, like USDC, and code that assumes 18 will be off by a factor of 1012.
Faucet#
The faucet(opens in a new tab) sends test assets to your wallet. You sign a message to prove you control the address; the message authorises no transfer and costs nothing.
Loading the current faucet policy…
- Cooldowns apply per asset, to both the claiming wallet and the receiving address.
- Need more for a larger test? Ask the team.
Wrapped tZROAR#
WtZROAR works like WETH: call deposit() with tZROAR attached to receive the same amount of WtZROAR, and withdraw(amount) to unwrap. Find it in the explorer's token list and use its contract page to call these functions.
No value, ever#
Test assets only
tZROAR, tZUSD and WtZROAR have no monetary value. They cannot be redeemed, have no peg or collateral, will never be bridged, and do not convert to Mainnet tokens. Do not list them with a price.Something wrong or missing on this page? Send developer feedback.
