Question 1

What is the WNCG bridge?

Accepted Answer

The WNCG bridge is a web app that moves Wrapped NCG (WNCG), an 18-decimal ERC-20 token, between Ethereum (L1) and Abstract (L2), a ZK Stack chain. Deposits lock WNCG on Ethereum and mint it on Abstract; withdrawals burn it on Abstract and unlock it on Ethereum, all routed through the ZK Stack Bridgehub.

Question 2

How long does it take to bridge WNCG to Abstract?

Accepted Answer

Depositing WNCG from Ethereum to Abstract takes roughly a few minutes — funds mint on Abstract once the L1 transaction is finalized. A first-time deposit requires two wallet signatures: an ERC-20 approve, then the deposit.

Question 3

How long does a WNCG withdrawal from Abstract to Ethereum take?

Accepted Answer

Withdrawals from Abstract (L2) to Ethereum (L1) follow ZK Stack finality: the batch is committed and proven on Ethereum, with a security delay, taking about 3 hours and up to roughly 24 hours when the network is busy. After it matures you claim it on L1 in a separate transaction to receive your WNCG.

Question 4

Which wallets can I use with the WNCG bridge?

Accepted Answer

The bridge uses RainbowKit, so any EVM wallet works — MetaMask, Rabby, Coinbase Wallet, Rainbow, and WalletConnect-compatible mobile wallets.

Question 5

What are the WNCG token contract addresses?

Accepted Answer

WNCG on Ethereum (L1) is 0xf203Ca1769ca8e9e8FE1DA9D147DB68B6c919817. WNCG on Abstract (L2, chain ID 2741) is 0x3a058F406654B908a60cBE296faC03C7bF1c6769. Both are 18-decimal ERC-20 tokens.
