Building Privacy-First Web3 & AI Apps with Oasis Sapphire and GetBlock

oasis protocol
As AI-driven applications move onchain, one issue keeps resurfacing: how do you handle sensitive data without breaking decentralization or compliance? Most EVM chains expose all state by default, which makes them a poor fit for identity, AI agents, and regulated DeFi.

This is where Oasis Network and GetBlock come together.

GetBlock now supports Oasis Sapphire, Oasis’s confidential EVM runtime, making it easier for developers to deploy privacy-aware smart contracts and AI-enabled applications using familiar tooling.

Why Oasis Sapphire Is Different

Oasis Sapphire is a production EVM with programmable privacy built in. Developers can choose which parts of state or execution are confidential, instead of forcing everything to be public or fully private.

Key technical properties:

  • Smart contracts run inside Trusted Execution Environments (TEEs)
  • Sensitive inputs and state remain encrypted end-to-end
  • Privacy is optional and composable, not all-or-nothing
  • Solidity-compatible, no custom language required

This makes Sapphire particularly well-suited for:

  • AI agents handling proprietary strategies or user data
  • Identity and access control systems
  • Compliance-aware DeFi
  • Applications that require private logic but public settlement

What GetBlock Adds for Developers

With GetBlock’s Oasis support, developers don’t need to self-host or manage infrastructure to get started.

You get:

  • JSON-RPC and WebSocket endpoints
  • Mainnet and Testnet access
  • Shared or dedicated nodes
  • Archive data support
  • 99.9%+ uptime SLA

From a workflow perspective, this means you can plug Oasis Sapphire into existing tooling (Hardhat, Foundry, wallets, indexers) the same way you would with any other EVM chain.

Privacy Meets UX and Security

Oasis’s privacy model also extends to user authentication. Sapphire supports modern security patterns like:

  • Passkeys
  • TouchID / biometric auth
  • TOTP-based 2FA

This makes it possible to build applications where users don’t need to choose between usability, privacy, and compliance.

When Does This Matter?

If your application:

  • processes sensitive user inputs
  • runs AI or agent logic onchain
  • needs selective disclosure instead of full transparency
  • targets enterprise or regulated environments

then a confidential EVM is no longer a “nice-to-have,” it’s infrastructure.

With GetBlock providing managed access to Oasis Sapphire, the barrier to building these systems drops significantly.

Final Thoughts

Web3 and AI are converging quickly, but most onchain environments were never designed for private computation. Oasis Sapphire fills that gap by bringing confidentiality to the EVM itself, and GetBlock makes it accessible without operational overhead.

For developers building the next generation of AI-driven, privacy-aware dApps, this combination is worth a serious look.

Docs and RPC access are available directly via GetBlock’s Oasis integration.
