Discover Oasis Sapphire: The Future of Smart Privacy on EVM

What’s Oasis Sapphire?

Oasis Sapphire is the first production-ready confidential EVM-compatible ParaTime on the Oasis Network. It lets developers build smart contracts that are not just decentralized and scalable, but also private by design.

  • End-to-end encrypted state

  • Confidential randomness

  • Full EVM compatibility (Hardhat, MetaMask, Remix)

Why Should You Care?

Smart Privacy: You decide the confidentiality spectrum (public ↔ fully private).

Perfect for privacy-preserving DeFi, auctions, vaults, or even on-chain AI.

Smooth Migration
Already on Ethereum? No need to rewrite everything. Port your Solidity contracts using the same tools you already know: Hardhat, Ethers, MetaMask.

Speed + Cost

  • ~6 second finality

  • Gas fees more than 99% cheaper than Ethereum

  • Scalable thanks to multiple ParaTimes running in parallel

Level Up with ROFL

ROFL (Runtime Off-chain Logic) is a framework for secure, verifiable off-chain computation.
Use cases include oracles, AI workloads, and backend services.

Dev Kit Essentials

Docs: https://docs.oasis.io/build/sapphire/

  • Sapphire-Hardhat plugin for quick setup

  • Testnet endpoints and faucets to start building

Real-World Example

Oasis Safe (a Gnosis Safe fork) is live on Sapphire: a secure, programmable wallet with confidentiality built in.

Why 2025?

  • ROFL mainnet is live, enabling confidential + hybrid off-chain apps today

  • Sapphire 1.0 launched August 2025, a stable and production-ready runtime

Sapphire is a big step forward for EVM devs. Confidentiality isn’t just a "nice to have" anymore, it’s becoming core to DeFi, AI, and real-world dApps. Excited to see how builders leverage ROFL + Sapphire to push privacy into the Web3 mainstream!!
