AI Agent Execution
How autonomous AI agents operate on-chain with deterministic execution, native oracle access, and gas-metered compute.
Xhavic provides first-class protocol support for autonomous AI agents operating on-chain. Unlike other L2s that treat AI integration as an application-layer concern, Xhavic builds agent support directly into the execution environment.
Why AI Agents Need a Different Chain
Standard EVM chains create friction for AI agents:
- Non-deterministic ordering โ MEV and gas auctions make multi-step strategies unpredictable
- External oracle dependencies โ Agents need real-time data but must rely on third-party oracle networks
- Unpredictable costs โ Gas price volatility makes budgeting impossible for autonomous systems
- High latency โ 12-second block times on Ethereum are too slow for real-time decision loops
Xhavic solves each of these at the protocol level.
Agent-Friendly Features
Deterministic Execution Ordering
The sequencerโs threshold encryption and time-weighted ordering ensure that multi-step agent strategies execute in the intended order without front-running or sandwich attacks.
Native Oracle Access
AI agents read price feeds and data directly from EVM precompiles at addresses 0x00...F0 through 0x00...FF. No external contract calls, no bridge latency, no third-party dependencies.
// Direct precompile call โ no oracle middleware needed
(bool success, bytes memory data) = address(0xF0).staticcall(
abi.encode("ETH/USD")
);
uint256 price = abi.decode(data, (uint256));
Gas-Metered Compute
Fixed, low gas costs allow agents to budget their operations precisely:
| Operation | Gas Cost | USD Cost |
|---|---|---|
| Oracle price read | 50 gas | < $0.001 |
| Token swap | ~150,000 gas | ~$0.12 |
| Multi-step strategy (5 ops) | ~500,000 gas | ~$0.40 |
Sub-200ms Latency
With 2-second block times and sub-200ms soft finality, agents can operate in real-time decision loops โ reading data, computing strategies, and executing transactions within a single cycle.
Dual Wallet for Agents
AI agents can leverage both wallet types:
- Instant Wallet โ For time-sensitive DeFi operations (swaps, arbitrage, liquidations)
- Secured Wallet โ For high-value operations where human oversight is beneficial. The 24-hour escrow window allows a human operator to review and cancel agent actions if needed.

Floating-Point Precompiles
Xhavic includes custom precompiles for floating-point arithmetic, essential for ML inference and financial calculations:
| Precompile | Operation | Gas Cost |
|---|---|---|
0x00...E0 | fp64_multiply | 30 gas |
0x00...E1 | fp64_divide | 35 gas |
0x00...E2 | fp64_sqrt | 40 gas |
0x00...E3 | fp64_exp | 50 gas |
These precompiles are audited independently as part of the core protocol audit.
