An EVM-compatible testnet on the Oasis Network, Emerald enables low-fee, high-throughput Solidity dApp testing using ROSE gas on scalable ParaTime architecture.
Oasis Emerald Testnet is the EVM-compatible test network for the Oasis Network’s Emerald ParaTime, using ROSE as gas to safely trial Solidity dApps, wallets, cross-chain bridges, and infrastructure. Typical performance: ≈6s block time, single-digit gwei gas prices (simple transfers often <0.001 ROSE), and hundreds of TPS capacity; activity is developer-driven and spikes around releases and hackathons, lower than mainnet.
Emerald Testnet is unique due to Oasis’s ParaTime architecture, which isolates EVM execution from the consensus layer to minimize shared congestion and keep fees low and predictable. Compared with many EVM chains it offers ≈6s finality (vs ≈12s on Ethereum L1), sub-cent gas for simple transfers (vs dollar-level on L1), and hundreds of TPS (vs ~15 TPS on Ethereum), while retaining standard Ethereum tooling and paying gas in ROSE.
Oasis Emerald Testnet uses ROSE as the gas token for transaction fees. You can obtain ROSE by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge ROSE to Oasis Emerald Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Oasis Emerald Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Oasis Emerald 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 Oasis Emerald 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 ROSE on Oasis Emerald Testnet, ensure your wallet is connected to the Oasis Emerald Testnet network, enter the recipient's address, specify the amount of ROSE to send, review the gas fee, and confirm the transaction in your wallet.
