Starknet Network Facts

When to Use

• Reasoning about chain behavior assumptions in contract logic.
• Validating time, fee, and transaction-version dependencies.

When NOT to Use

• Contract implementation details unrelated to chain behavior.

Quick Start

1. Identify assumptions in code about tx versions, fee tokens, and timing.
2. Verify assumptions against current network behavior before release.
3. Add tests for boundary behavior tied to block timing or tx metadata.

Core Focus

• transaction version expectations
• fee token and bounds assumptions
• block-time-sensitive logic
• sequencer and inclusion model implications

Workflow

• Main network-facts workflow: default workflow

starknet.js Example

import { RpcProvider } from "starknet";

const provider = new RpcProvider({ nodeUrl: process.env.STARKNET_RPC! });
const latest = await provider.getBlock("latest");

console.log({
  blockNumber: latest.block_number,
  l1GasPrice: latest.l1_gas_price,
  l2GasPrice: latest.l2_gas_price,
});

Error Codes and Recovery

Code	Meaning	Recovery
SNF-001	RPC/network fact unavailable	Retry with a fallback RPC and compare outputs before acting.
SNF-002	Conflicting tx-version assumption	Re-check references and update guards/tests for current tx version behavior.
SNF-003	Fee-token assumption mismatch	Add explicit fee-token checks and fee-bound regression tests.
