Frequently Asked Questions

General​

What is Xphere?​

Xphere is a Layer 1 blockchain with a Dual-Chain Architecture: a Main Chain running optimized PBFT consensus (1-second finality), and a Proof Chain securing the network via PoW (xpHash). See the Whitepaper.

Is Xphere EVM-compatible?​

Yes. Xphere targets Cancun-level EVM equivalence. Any contract that compiles for Ethereum mainnet runs on Xphere without modification. See EVM Compatibility.

What is the native token?​

XP, with 18 decimals. It is used for gas, staking, and protocol governance.

What are the Chain IDs?​

  • Mainnet: 20250217
  • Testnet: 1998991

See Network Info for the full parameter list.

Wallets​

Which wallets support Xphere?​

Any EVM-compatible wallet (MetaMask, Rabby, Trust Wallet, etc.) plus the native Zigap wallet. See Wallet Setup.

How do I get testnet XP?​

Use the faucet. Rate-limited per address.

How do I bridge from Ethereum?​

See the Bridge guide.

Mining​

What hardware do I need?​

A CPU with ≥ 4 cores. xpHash is CPU-optimized — GPUs/ASICs are not used. See Mining Requirements.

What's the xpHash hard fork?​

A consensus upgrade to the Proof Chain PoW algorithm, already active on both networks (mainnet block 1,740,000, testnet block 327,400). Mining now requires the IceRiver XP0 ASIC. See xpHash Fork.

How are rewards calculated?​

A reward is minted every 60 blocks and split 20% Foundation / 40% Miner / 40% Union. The emission reduces 26.28% per year, and 50% of transaction fees are burned. See Mining Rewards.

Development​

Where do I start as a developer?​

Developer Quickstart — deploys your first contract in 10 minutes.

Does Hardhat work?​

Yes. Just add Xphere as a network in hardhat.config.ts. See Smart Contracts.

Is there a public RPC?​

Yes — see Public RPC Endpoints. For production, run your own Endpoint Node.

Can I subscribe to events via WebSocket?​

Yes. wss://en-hkg.x-phere.com/ws (mainnet) and wss://testnet.x-phere.com/ws (testnet).

Nodes​

What's the difference between Endpoint Node, Validator Node, and Mining Node?​

  • Endpoint Node (XEN) — Read-only JSON-RPC interface. Anyone can run one.
  • Validator Node — Main Chain PBFT consensus participant. Restricted to council members.
  • Mining Node — Proof Chain miner. Anyone can run one for rewards.

See Node Guide.

Do I need to re-sync after the xpHash fork?​

No. The fork is in-place; existing chaindata remains valid. See xpHash Fork — Node Operators.

Security​

Has Xphere been audited?​

Audit reports are published as they become available — check the GitHub organization and Foundation announcements.

How do I report a vulnerability?​

Email security@x-phere.com with the subject [SECURITY]. Do not open a public GitHub issue.
