Interoperability
Connect any chain to HQ
HQ is the Layer-0 that links every chain together. Bridge assets from Ethereum, Solana, Bitcoin and more into HQ — and move them with sub-second, post-quantum-secured finality.
🛡️ Quantum-safe bridge · secured by ML-DSA-44, not breakable ECDSA
1. Pick a chain & asset
2. A staked relayer attests your deposit (PQ-signed)
3. Wrapped asset lands in your HQ wallet

Your bridged portfolio
Nothing bridged yet. Bridge an asset to see it here.
Wrapped assets are standard HQ tokens — send them, trade them, or use them in any HQ appchain. Burn them here to withdraw back to the source chain.
How it works & honest status. Each external asset is represented on HQ as a wrapped token with a deterministic address, minted when a staked relayer attests a deposit and burned to withdraw — every cross-chain message is signed with post-quantum ML-DSA-44, which is what makes this bridge quantum-safe. This is a live testnet: the HQ node acts as the relayer so you can try the full flow end-to-end. Production mainnet bridging adds deposit contracts/light clients on each source chain, a decentralized staked relayer set, and a security audit before it custodies real funds.
