Testnet Status & Faucet
Everything described on this site is the NetZero public testnet. USDn on the testnet has no value, is minted freely for testing, and will not carry over to a mainnet. Validator keys are test keys. Treat the network as a place to build and break things.
Current state
| Component | Status |
|---|---|
| Validator network (10 seats, 3 s blocks, 1-block finality) | live |
| USDn gas, base fee floor, protocol fee split | live |
| Incentive Pool | live |
agent_* API (local nodes) | live |
nzc_* RPC, finalized / safe tags | live |
| Public RPC endpoint | live: http://165.227.236.60 (HTTP), ws://165.227.236.60/ws (WebSocket); namespaces eth,net,web3,nzc |
| Bootnode | compiled into the node; enode://9cd776c3…@165.227.236.60:30303 |
| Faucet | not yet; mine instead (own node or against the public RPC), or ask the team |
| Explorer | this site's Explorer, live on the public testnet: blocks, transactions, carbon, mining shares, validator health |
| Mining shares paid to miners | live from block 29400 (keccak256 shares; 40% of fees + 0.05 USDn per block to miners) |
| USDn minting against attested deposits | next |
| ValidatorSet, Carbon Fund, CDRT contracts | next |
The Roadmap has the full list with what "next" means.
Getting test USDn
On a local testnet, the genesis funds a faucet account with 10,000,000 test-USDn. Its key is derived deterministically (see cmd/nzc-testkeys in the repository), and the tool can send from it:
nzc-testkeys send http://127.0.0.1:8699 0xYourAddress 100 # 100 test-USDnOn the public testnet, a web faucet will hand out a fixed amount per address per day. Until it is live, ask the team for test-USDn, or run a node and mine: the first share pays without any balance.
The public testnet runs on one server in London (ten validator seats plus the RPC node). It is a testnet; it can be reset, and this page will say when.
What "no value" means in practice
- Do not build anything that depends on testnet USDn being redeemable. It is not.
- The chain may be reset. When it is, the genesis hash changes and this page says so.
- Testnet parameters are deliberately short (an epoch is 10 minutes, a "year" of the validator schedule is about four hours) so that every mechanism is exercised within a day.
