What is this?
A custodial bridge between native Zero Chill Units (ZCU) and its ERC-20 twin on Ethereum, wZCU (0x61b1F4D5db2436C089593828C26F21e25c4A9C9d). wZCU is minted when you wrap and burned when you unwrap, so total supply always equals the ZCU held in the bridge reserve — 1:1, verifiable on both chains.
How much does it cost?
Wrap (ZCU → wZCU) is 5%. Unwrap (wZCU → ZCU) is free. Fees are set by the operator and shown live on the swap form before you confirm.
Why custodial and not a smart contract?
Native ZCU transfers on the Zero Chill Units chain don't touch our bridge contract, so somebody has to custody the native coin. We keep that side deliberately simple: one operator wallet, and a wZCU contract that only mints against a confirmed ZCU deposit and only burns on unwrap. There is no pre-mined float sitting around, so wZCU total supply is a live proof-of-reserves number anyone can check.
Which networks and tokens can I send from?
Native ZCU on the Zero Chill Units Mainnet (chain ID 90031273), or wZCU on Ethereum. We do not offer stablecoin or ETH on-ramp swaps.
Which assets can I receive?
Native ZCU (paid to any Zero Chill Units 0x… address) or wZCU (paid to any Ethereum 0x… address).
How long does a swap take?
Around 5 minutes end-to-end. We wait for chain-specific confirmations on your deposit, then sign and broadcast the payout from the hot wallet. Slower chains (Ethereum mainnet) take longer than the Zero Chill Units network.
What if I send the wrong token or wrong chain?
Funds sent on an unsupported chain or with an unsupported token aren't picked up automatically. Contact the Help Center with your order ID and deposit tx hash — manual recovery may be possible.
What if my destination address is wrong?
We can only send to the address you provided at order creation. Double-check before confirming — payouts can't be reversed.
What happens if the quote expires before I pay?
Each quote is valid for the expiry window shown on the order page (15 minutes by default). Late deposits are held for manual reconciliation — contact support with your order ID.
Do you take custody of my funds?
Yes — that's the model. The bridge is custodial by design. The ZCU backing wZCU stays in the operator wallet for as long as that wZCU is in circulation, and is released the moment it's burned on unwrap.
Where can I track my swap?
After creating an order you're redirected to a live status page that auto-refreshes through every stage. Your browser also keeps a local history of recent swaps on /swap.
Is there a minimum or maximum order size?
Minimums and maximums are shown live on the swap form and enforced at order creation. They can change based on hot-wallet liquidity and operator limits.
