SYSCALL SDK
[ BLOCKCHAIN_TO_REAL_WORLD_BRIDGE ]
The first high-performance I/O layer designed for the real-time economy. Empower your smart contracts with "hands" to interact with the physical world via Emails, SMS, and AI, powered by MegaETH.
Smart contracts are inherently sandboxed; they cannot communicate with the outside world without brittle, centralized intermediaries. Syscall SDK solves the "Action Gap." While traditional Oracles bring data in, Syscall enables trustless outbound actions.
Our infrastructure removes the need for maintaining private servers, managing complex API keys, or building custom "watchers." Syscall provides a unified interface to trigger physical world events directly from on-chain logic.
We believe Web3 infrastructure should be as permissionless as the blockchain itself. Syscall offers a "Pay-as-you-go" model with absolute freedom:
100% On-chain. Pay per use with your wallet. Simple, fast, and commitment-free.
You don't need to be a developer. Use our intuitive web interfaces to send cryptographically verified emails or SMS alerts directly from your wallet.
Build dApps that communicate. Use new Syscall(window.ethereum) to turn your interface
into a communication powerhouse without a dedicated backend.
Secure your automation pipelines. Trigger tasks from Node.js scripts or bots without managing centralized API keys. Decentralized I/O for autonomous agents.
Standard Oracles bring data onto the blockchain. Syscall is a "Reverse Oracle"—it listens for on-chain events and triggers real-world actions like emails or API calls securely.
Absolutely. Your security is enforced by the blockchain. You only pay when you sign a transaction with your wallet, ensuring you have total control over every action.
MegaETH offers sub-second block times. This allows Syscall to deliver emails and SMS almost instantly, matching the speed of traditional Web2 services while maintaining Web3 decentralization.
Yes. Syscall is perfect for DAOs that need to notify members of governance votes, treasury movements, or emergency actions directly via off-chain channels.
