Quickstart

Analyze your first Solana transaction

Analyze a confirmed transaction

Get a full analysis of any mainnet transaction:

opendev tx 4W8cbHAkjJC3jKdFY39JFXtTakf5JK9rz6jyGPbbpKEqhweRYzwjveZasFin46WuApDeLoQRHieG3t5b3T7VXMRR --network mainnet

Output includes:

• Compute units used
• CPI call tree (cross-program invocations)
• Account state diffs
• AI-generated optimization suggestions (if configured)
• Rule-based insights

---

Output formats

Full analysis as JSON

Pipe into jq, save to file, process programmatically:

opendev tx <signature> --json

CSV report

Save structured data for spreadsheets or databases:

opendev tx <signature> --csv --output report.csv

---

Batch processing

Analyze multiple transactions from a JSON file:

opendev batch ./signatures.json --csv --output batch-report.csv

Before running batch commands, you’ll need a signatures.json file. The repo ships with a sample at the root. If you installed only via npm/curl, grab it:

curl -O https://raw.githubusercontent.com/OpenSubmissionn/Open_DevTool/main/signatures.json

Schema: { "network": "mainnet", "signatures": ["...", "..."] }

Simulate unsigned transactions

Test transactions without on-chain confirmation:

From a base64 blob

opendev simulate <base64-blob>

From a file

opendev simulate ./sample-tx.b64

From source code

TypeScript

opendev simulate ./build_tx.ts --network devnet

Runs npx -y tsx build_tx.ts and uses the last base64 output line.

Rust

opendev simulate ./build_tx.rs    # runs `cargo run --release`
opendev simulate ./my-rust-proj   # directory with Cargo.toml

JavaScript

opendev simulate ./build_tx.js --network devnet

Runs node build_tx.js and uses the last base64 output line.

By default, opendev simulate executes user-provided scripts. Pass --no-exec if you want to refuse source-file input (useful in CI).
