Frequently asked questions

U2U Solaris is the Uniultra mainnet (EVM-compatible) that uses the U2U token for gas, purpose-built for low-fee, fast-finality transactions across DeFi, payments, NFTs, gaming, and cross-chain apps. It enables a bridge-native experience so users can move assets in and out quickly for trading, liquidity provision, and on-chain asset issuance with predictable costs. Live performance metrics—average gas cost, block speed, TPS, and active users—are available via the official explorer at uniultra.xyz and consistently indicate sub-cent fees and second-level confirmations versus legacy L1s.

U2U Solaris stands out with a bridge-first architecture, deterministic finality, and stable low gas priced in U2U, optimizing cross-chain transfers and dApp UX while retaining full EVM tooling compatibility. Compared with other networks, it delivers second-level block times and high throughput suitable for high-frequency DeFi, and you can benchmark it in real time—avg gas cost, block speed, TPS, and user activity—via the official explorer linked at uniultra.xyz to compare against Ethereum, BNB Chain, or Polygon.

U2U Solaris uses U2U as the gas token for transaction fees. You can obtain U2U by bridging from other chains or purchasing using thirdweb Bridge.

To bridge U2U to U2U Solaris, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select U2U Solaris as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.

To build on U2U Solaris 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 U2U Solaris 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 U2U on U2U Solaris, ensure your wallet is connected to the U2U Solaris network, enter the recipient's address, specify the amount of U2U to send, review the gas fee, and confirm the transaction in your wallet.
