An EVM-compatible blockchain mainnet, Swell Chain (Chain ID 1923) uses ETH as its native currency and delivers fast, low-cost transactions for Ethereum dApps and DeFi.
Swell Chain is an Ethereum Layer-2 mainnet that uses ETH as its native gas and is purpose-built around Swell’s restaking ecosystem (swETH/rswETH). Core use cases include low-fee, fast-finality DeFi (DEXs, lending, perps), yield strategies, and AVS-integrated apps that natively leverage restaked ETH as collateral and rewards. Performance is L2-grade—seconds-level blocks, sub-cent to low-cent average gas for simple transfers, and high throughput (hundreds TPS under load); check the network explorer for live averages on gas, block time, TPS, and activity.
Swell Chain is uniquely restaking-native: it provides first-class support for swETH/rswETH across ecosystem tooling and incentives so dApps can tap restaking yield and operator sets by design. It maintains ETH as the gas token for seamless UX while concentrating deep Swell liquidity and partnerships to improve capital efficiency and security for restaking-centric applications. Practically, users and builders get lower effective cost of capital plus competitive L2 performance metrics (low average gas, seconds-level blocks, high TPS) versus general-purpose Ethereum L2s.
Swell Chain uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge.
To bridge ETH to Swell Chain, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Swell Chain as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Swell Chain 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 Swell Chain 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 Swell Chain, ensure your wallet is connected to the Swell Chain network, enter the recipient's address, specify the amount of ETH to send, review the gas fee, and confirm the transaction in your wallet.
