Core Features

Protocol-level timer support enables truly autonomous agents. Actors can schedule their own execution using a hierarchical calendar queue with dynamic gas bidding.Learn more: Timers & Scheduler
Write smart contracts in Python with full determinism guarantees. The Actor VM provides a sandboxed execution environment with precise resource metering.Learn more: Actor VM
Separate pricing for computation (Cycles) and data (Cells) with independent EIP-1559 style fee markets. Pay fairly for what you actually use.Learn more: Fee Model
Run AI models, fetch external data, or perform heavy computations off-chain with cryptographic verification. VRF-based runner selection ensures decentralization.Learn more: Off-Chain Compute
