Frequently asked questions

Worlds OP is an OP Stack Ethereum L2 testnet that uses ETH as gas, built for developers to deploy and iterate on EVM smart contracts, cross-chain bridges, and dApps before mainnet. It supports standard Ethereum tooling (wallets, Hardhat/Foundry) and faucet ETH for low-cost testing. Metrics note: no chain-specific benchmarks are publicly published as of Sep 2025; expect OP Stack testnet norms of sub-cent average gas cost, ~2-second block speed, and roughly 20–100+ TPS with variable network activity.

Worlds OP stands out by offering Ethereum-equivalent execution via the OP Stack in a testnet environment optimized for interoperability and bridge validation, giving near-mainnet behavior with rapid iteration and low fees. It inherits Optimism’s optimistic rollup security and Ethereum settlement while supporting standard L1↔L2 messaging and bridging patterns for realistic cross-chain testing. For comparison, OP Stack networks typically deliver gas costs ~10–100x cheaper than Ethereum L1, ~2s block speed, and higher TPS; specific Worlds OP averages are not publicly reported and may vary with testnet configuration and activity.

Worlds OP uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).

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

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