ETH Bridge (qETH)

Bridge ETH from Base mainnet to RougeChain as qETH, and back.

Status: LIVE (hardened R1 bridge), tested end-to-end; deposits reopened 2026-10-05 through the contract's depositETH with automatic claiming. qETH uses classical Base-side authorization (the RougeBridge owner and release key is a single operator hot key; unaudited) and is outside the scope of the V3 post-quantum XRGE bridge.

Deposit (ETH → qETH)

Step 1: Send ETH to the Bridge

Connect your MetaMask (or other EVM wallet) to Base and call depositETH(rougechainPubkey) on the RougeBridge contract (the Bridge page does this for you), passing your RougeChain public key. This emits a BridgeDepositETH event carrying your recipient key.

Step 2: Automatic claim

The relayer's deposit watcher sees the event and claims it for you — qETH is minted to the RougeChain key you encoded in the deposit, once the deposit reaches the required confirmation depth (QV_BRIDGE_MIN_CONFIRMATIONS, default 6 Base confirmations). No manual claim step is needed.

The node verifies before minting:

• The transaction exists on Base and was sent to the correct contract
• The amount and sender match the deposit
• The transaction has at least the required confirmation depth (default 6)
• It hasn't been claimed before (auto-claim and manual claim share one dedup store)

Manual claim: the node's manual claim route (POST /api/bridge/claim, which needs a signature from the depositing EVM wallet) is closed at the public mainnet endpoint. A deposit that the watcher has not credited is handled by the operators; the Bridge page tracks the deposit until it is credited.

Conversion Rate

1 ETH = 1,000,000 qETH units (6 decimal precision). Deposit amounts should be multiples of 0.000001 ETH (1e12 wei); smaller remainders cannot be represented on L1.

For example, depositing 0.01 ETH gives you 10,000 qETH units.

Withdraw (qETH → ETH)

1. Go to the Bridge page and select the Bridge Out tab
2. Select ETH as the token
3. Enter the amount of qETH to bridge out
4. Enter the Base address to receive ETH
5. Click Bridge Out

The transaction is signed client-side (your private key never leaves the browser), then:

• qETH is burned on RougeChain
• A pending withdrawal is created
• The bridge relayer picks it up and sends ETH to your EVM address
• Release status (pending / failed / refunded) shows on the Bridge page. Automatic refunds are disabled in production; a release that can't be completed is handled by the operators.

A 0.1 XRGE fee is charged for the withdrawal transaction.
