Frequently asked questions

F(x)Core is the Function X mainnet built with the Cosmos SDK/Tendermint, using FX as the native token for gas, staking, and on-chain governance; it combines f(x)EVM for Ethereum-compatible smart contracts with IBC for Cosmos interoperability. Primary use cases include cross-chain DeFi and asset transfers through its bridge, Web3 payments tied to the Pundi X ecosystem, NFTs, and validator/delegator staking. Performance profile: low gas fees (often sub-cent), block times measured in seconds, and throughput in the high double- to triple‑digit TPS range, suitable for high-frequency cross-chain dApps.

F(x)Core uniquely pairs native IBC interoperability with an integrated EVM (f(x)EVM), letting developers route liquidity between Ethereum and Cosmos while using familiar Solidity tooling and wallets like MetaMask with fast finality. Compared to Ethereum L1, it delivers far lower fees and faster blocks, and offers higher throughput than Bitcoin and speeds comparable to leading Cosmos zones—an advantage for bridges and omnichain applications. It also differentiates with tight Pundi X payment stack integration plus delegated staking, slashing, and on-chain governance securing the network.

F(x)Core Network uses FX as the gas token for transaction fees. You can obtain FX by bridging from other chains or purchasing using thirdweb Bridge.

To bridge FX to F(x)Core Network, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select F(x)Core Network as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.

To build on F(x)Core Network 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 F(x)Core Network 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 FX on F(x)Core Network, ensure your wallet is connected to the F(x)Core Network network, enter the recipient's address, specify the amount of FX to send, review the gas fee, and confirm the transaction in your wallet.
