Starknet Network Facts

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](workflows/default.md)

References

• Module index: [references index](references/README.md)

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. |
