Oasis Emerald is the Oasis Network’s EVM-compatible ParaTime on Mainnet that runs Solidity/Vyper smart contracts and uses ROSE for gas. Typical transaction fees are sub-cent (<$0.01), blocks finalize in about 6 seconds, and throughput reaches hundreds to ~1,000 TPS, making it well-suited for DeFi, NFTs, gaming, and cross-chain dApps. Builders often pair Emerald’s public EVM with Sapphire (confidential EVM) to keep sensitive logic private while keeping liquidity and UX on Emerald.
Emerald is unique due to Oasis’s ParaTime architecture, which separates execution from consensus and isolates runtimes to minimize congestion and deliver predictable low fees and fast finality. Compared with Ethereum L1 (~12–15s blocks, ~15 TPS, $1+ average fees), Emerald typically posts ~6s blocks, higher throughput (hundreds TPS), and sub-cent gas while remaining a drop-in for Ethereum tooling like MetaMask and Hardhat. It also composes natively with Sapphire for on-chain privacy—functionality most EVM chains do not offer.
Oasis Emerald uses ROSE as the gas token for transaction fees. You can obtain ROSE by bridging from other chains or purchasing using thirdweb Bridge.
To bridge ROSE to Oasis Emerald, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Oasis Emerald as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
