An EVM-compatible testnet using ETH (Chain ID 1924), Swellchain Testnet provides a stable, low-cost environment for dApp testing with standard Ethereum tooling.
Swellchain Testnet is a public, Ethereum-compatible testing network that uses test ETH as its native gas token, designed to safely prototype and validate cross-chain bridge flows before mainnet. It provides a sandbox for deploying and auditing smart contracts, wallet/relayer integrations, and end-to-end QA of asset transfers without real economic risk. Primary use cases include dApp integration testing, load and stress experiments, and CI pipelines for bridge transactions.
Compared to generic testnets, Swellchain Testnet is tailored for bridge-centric workflows—full EVM tooling support, ETH-denominated gas, and predictable developer ergonomics for multi-chain simulations. As of September 2025, official performance benchmarks (average gas cost, block speed, TPS, on-chain activity) are not publicly published; verify live metrics via the chain’s block explorer or by sampling RPC data (eth_gasPrice, block timestamps, transaction counts) during your test window. Treat observed testnet metrics as non-representative of mainnet and use them for relative, not absolute, performance comparisons.
Swellchain Testnet 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 Swellchain Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Swellchain Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Swellchain Testnet 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 Swellchain Testnet 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 Swellchain Testnet, ensure your wallet is connected to the Swellchain Testnet network, enter the recipient's address, specify the amount of Eth to send, review the gas fee, and confirm the transaction in your wallet.
