Building multichain agents is hard. Developers often face fragmented SDKs, incompatible transaction formats, multiple RPC patterns, and the challenge of coordinating state across different networks. ROFL (Runtime Offchain Logic), now live on Oasis Mainnet, simplifies this with verifiable off-chain execution and native cross-chain key management.
What is ROFL Key Generation?
ROFL introduces a cryptographic key derivation system within trusted execution environments (TEEs). It allows applications running inside TEEs to:
- Generate wallet private keys for multiple blockchains natively
- Support multiple elliptic curves:
secp256k1(EVM-compatible chains) andEd25519(Solana, Aptos) - Keep keys fully isolated inside the enclave, with secure on-chain access control
This design eliminates traditional trust assumptions and removes the need for bridges or wrapped tokens for cross-chain wallet management.
How It Works
- Remote Attestation: When an agent or app is deployed on ROFL, it undergoes remote attestation, proving its integrity to the network.
- Key Generation: During this process, cryptographic keys are derived for the target chains directly inside the TEE.
- Native Transactions: The app uses these keys to submit transactions directly via RPC calls. Keys never leave the enclave.
- Cross-Chain Flexibility: The TEE can derive keys for different elliptic curves simultaneously, enabling a single agent to control wallets on multiple networks.
This approach reduces development overhead while ensuring cryptographic guarantees for users.
Why It Matters
- Unified Wallet Management: Control wallets across multiple chains from a single codebase.
- Reduced Trust Requirements: Users don’t need to trust developers with private keys.
- Simplified Multichain Operations: Direct native transactions replace complex cross-chain messaging.
- Hardware-Level Security: TEEs protect sensitive keys and transaction logic from external access.
Limitations: Assets must exist on each chain, and blockchains like Solana still require RPCs due to the lack of light clients.
Practical Examples
- Talos: Users’ keys are generated inside the TEE, eliminating the need to trust the Talos team. This enables fully autonomous treasury management across multiple chains.
- zkAGI: The Oasis_bot encrypts Hyperliquid API credentials inside the TEE, executing autonomous trading strategies securely. Future updates will expand cross-chain signing capabilities.
Conclusion
ROFL opens new possibilities for multichain agents. Developers can now build secure, verifiable, and privacy-preserving applications that operate across multiple ecosystems, while users gain confidence through cryptographic guarantees rather than trust in developers.
Start exploring ROFL to simplify your multichain development and build the next generation of autonomous blockchain agents.
