Frequently asked questions

ZKFair is a mainnet zkEVM Layer 2 built with Polygon CDK and Celestia data availability that uses USDC as the native gas, optimized for low-cost, high-throughput EVM apps. Core use cases include stablecoin payments/remittances, DeFi trading and lending, on-chain gaming, and microtransactions with predictable sub-cent fees. Typical performance: average gas cost often <$0.01 (in USDC), ~2s block times, hundreds+ TPS under load, and peak activity in the hundreds of thousands of daily transactions.

ZKFair stands out by charging gas in USDC and following a community-first, fair‑launch model, removing volatile gas exposure and simplifying UX for consumers and businesses. Under the hood it combines Polygon CDK zk proofs with Celestia DA to achieve low fees and fast finality while retaining Ethereum-level security and full EVM compatibility for seamless app migration. In practice this delivers consistently low, stable fees and seconds-level blocks with high TPS capacity, making it cost-competitive with leading L2s while offering clearer, dollar‑denominated economics.

ZKFair uses USDC as the gas token for transaction fees. You can obtain USDC by bridging from other chains or purchasing using thirdweb Bridge.

To bridge USDC to ZKFair, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select ZKFair as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.

To build on ZKFair you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.

To add ZKFair to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.

To send USDC on ZKFair, ensure your wallet is connected to the ZKFair network, enter the recipient's address, specify the amount of USDC to send, review the gas fee, and confirm the transaction in your wallet.
