sentri-simulator

Transaction simulator for Sentri invariant testing.

Simulates blockchain transactions against invariant specifications to detect violations before deployment.

Usage

[dependencies]
sentri-simulator = "0.1.3"
sentri-core = "0.1.3"
sentri-ir = "0.1.3"

Key Components

• TransactionSimulator: Executes transactions in sandboxed environment
• StateTracker: Tracks blockchain state changes during simulation
• InvariantChecker: Real-time violation detection
• ReportGenerator: Produces detailed violation reports

Example

use sentri_simulator::{TransactionSimulator, SimulationConfig};
use sentri_core::{Target, Invariant};

let config = SimulationConfig::default();
let mut simulator = TransactionSimulator::new(config);

let tx_data = vec![0x00, 0x01]; // Transaction data
let invariants = vec![/* your invariants */];

let result = simulator.simulate(&tx_data, &invariants, Target::EVM)?;
println!("Violations found: {}", result.violations.len());

Simulation Capabilities

• EVM transaction simulation
• Solana instruction simulation
• Move transaction simulation
• State change tracking
• Invariant violation reporting
• Gas estimation

Features

• Sandboxed execution (no external state)
• Multi-transaction scenarios
• State rollback/recovery
• Detailed violation reporting
• Performance metrics
