Chain 77702 · sps-testnet-1

A payment chain whose validators sign with ML-DSA-65.

Two cities produce every block. Wallets use the Ethereum JSON-RPC they already speak. The asset on this testnet is SPS. Post-quantum accounts exist beside those wallets, and they are not a costume on top of secp256k1.

What is post-quantum today

Consensus signatures are ML-DSA-65, NIST FIPS 204. Both validators must present that key. A later rotation to ed25519 is refused.

Peers authenticate with X25519 and ML-KEM-768 together, then prove a pinned ML-DSA-65 node key. Peer exchange is off. Each node accepts only the other city’s address.

Contracts can require an ML-DSA-65 signature through the verifier precompile. The SUSD issuer is a 2-of-3 ML-DSA-65 multisig. A single secp256k1 key cannot mint it.

  1. ValidatorsML-DSA-65 consensus keys. Chicago and Corpus Christi. Neither city holds two-thirds of the vote, so the chain stops if one stops.
  2. AccountsAn ML-DSA-65 contract account, a hybrid account that demands the wallet signature and the ML-DSA signature, and ordinary Ethereum accounts for gas.
  3. Still classicalMetaMask keys are secp256k1. The node id still has an ed25519 half beside the ML-DSA pin. This has not had an independent review. Do not park real value here.

Testnet faucet

One test SPS per address every 24 hours, up to five claims per source network. It has no monetary value. Keep enough for gas before using the launcher.

Token launcher

The factory is already deployed. This form asks your wallet to call createToken. The entire supply is minted once to you. The contract cannot mint again. Gas is SPS, and this site does not issue any.

Deployed on this testnet

SUSD on this network carries a test attestation. It is not a claim on dollars. Symbols SPS, SUSD, and WSPS cannot be created in the factory. WSPS itself is not deployed.
