I'm Samuele, based in Italy. I care about digital ownership and about software that answers to the person running it: what you buy should stay yours, what you hold should stay yours, and what you run should run on your own machines.
Two projects carry that idea at the moment. attest, an open standard for cryptographically-signed, buyer-held purchase receipts that outlive the store which issued them. And glaux, a minimal, crypto-agile EIP-7702 smart account that keeps one address on every EVM chain by construction.
| attest | An open standard + reference implementation for cryptographically-signed, buyer-held digital purchase receipts — verifiable offline, that outlive the store which issued them. No wallet, no blockchain, no server that has to stay alive. Published as IETF Internet-Draft draft-martinalli-open-purchase-receipts-00, with two independent verifier implementations (Python + TypeScript), Apache-2.0. |
| glaux | A minimal, crypto-agile EIP-7702 smart account: one address on every EVM chain by construction — no factories, no counterfactual deploys — with a 2-of-3 threshold on the operational path, P-256/secure-enclave signers, and sign-once/replay-many rotation. One birth blob demonstrated live on two public testnets: same account, same address, byte-identical configuration. Solidity (Foundry) + TypeScript SDK + Python tooling, MIT. Unaudited reference implementation. |
- Solidity (Foundry) — invariant testing, Slither + Aderyn gates in CI, deterministic CREATE2 deploys
- Python 3.11+ — type-safe (
mypy --strict), linted (ruff), tested (pytest) - TypeScript — strict compiler settings, tested end to end
- Self-hosting first — hardened Docker, read-only rootfs, dropped capabilities
- Auditable — small, readable codebases; no telemetry; secrets only via env
