Solo Testnet is an EVM-compatible test network for the bridge that uses test ETH and mirrors mainnet routes/contracts so you can validate cross-chain transfers end-to-end with no real funds. Primary use cases include integration testing, QA, and load/stress simulations across chains with faucet funding, deterministic relayer behavior, and resettable state for rapid iteration.
Unlike general-purpose testnets, Solo is purpose-built for cross-chain bridge workflows: pre-seeded test liquidity, configurable relayer delays/failures, and hooks to observe reorgs and message finality across L1/L2s. Key performance traits for comparison: avg gas cost ~$0 (faucet-funded), activity is burst-driven by scheduled load tests, and block speed/TPS are variable by campaign—use the in-app telemetry to see current block time, TPS, and gas metrics before benchmarking.
Solo 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 Solo Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Solo Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Solo 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 Solo 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 Solo Testnet, ensure your wallet is connected to the Solo 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.
