Hey, I'm Davi de Jesus 🇧🇷

Python Developer building open-source tools for the Bitcoin ecosystem.

X GitHub Proton Mail


Featured project — btc-toolkit

Tests

A Bitcoin tooling project built around two principles: zero external dependencies (Python standard library only) and no Bitcoin Core required (powered by public Bitcoin APIs).

Phase 1 — OP_RETURN Reader CLI (shipped)

  • Python 3.10–3.13 support
  • 18 unit tests
  • GitHub Actions CI
  • Decodes OP_RETURN messages from any Bitcoin transaction
  • Powered by the Mempool.space public API
$ op-return-reader 3ef1d49a3146bc30368de0d17c182c78497e61398572d86f5fbd7806ca47332e

  btc-toolkit v0.1.0 · Mempool.space API

  ✓ Found 1 OP_RETURN output(s):

  Output #1
  ├─ Size:     32 bytes
  ├─ Hex:      ff7f818a8090f0d3b682808884b0b08bc02eff7fd184dad7ef94a4e0a1f98f01
  └─ Message:  (binary data — not UTF-8 text)

Roadmap

  • Phase 2 — Address Balance Checker · inspect balances for Legacy, SegWit, and Taproot addresses
  • Phase 3 — Fee Estimator · estimate optimal fees from mempool conditions
  • Phase 4 — Block Info Explorer · retrieve block metadata and transaction summaries
  • Phase 5 — UTXO Set Inspector · inspect spendable outputs for any address
