Smart Contract Auditor. Blockchain Protocol Engineer.
Founder of Alcor — Decentralized AI Data Infrastructure.

I find critical vulnerabilities in DeFi protocols and build sovereign, Rust-native infrastructure for the decentralized economy. Based in West Africa. Building in the open.

About
Veritas in Umbra.

I'm Astrophel — a smart contract security researcher and protocol builder from West Africa. I hunt critical vulnerabilities in DeFi protocols on Code4rena and Cantina, and build decentralized infrastructure in Rust.

My work spans the full stack — Solidity auditing, Rust/Anchor development, zkML integration, and decentralized storage pipelines. I don't just find bugs. I understand the architecture deeply enough to break it.

Currently building Alcor Protocol — a decentralized voice data marketplace for underrepresented African languages, bringing local knowledge to the global AI economy.

Smart contract development on Solana. Payment contracts, CID storage, automated settlement.
Primary Chain
Solidity
EVM smart contract auditing on Jupiter, Morpho Blue, Rujira Credit, and more.
Auditing
zkML / EZKL
Lightweight ZK proof generation for on-device ML voice liveness and language verification.
Zero Knowledge

Python
ML model training, ONNX export, encryption tooling for the Alcor voice classifier pipeline.
ML / Scripting
{ }
TypeScript
Glue code, deployment scripts, bots. Bridges decentralized infra to traditional APIs.

Alcor Protocol.

The invisible data settlement layer for African languages.

Alcor
Decentralized Voice Data Marketplace

In Ursa Major, Alcor is the faint star hidden behind Mizar. Ancient armies used it as an eyesight test — if you could see Alcor, you were elite.

The AI industry has the same blind spot. Billions of African language speakers are invisible to AI models. Alcor pays locals to contribute verified voice data in Hausa, Swahili, Yoruba and more. Verified on-chain. Encrypted end-to-end. Instant settlement.

// How it works
01Contributor records voice — speaking in their native language about a bounty topic.
02zkML verifies on-device — proves human, correct language, accurate content. No server.
03Asymmetric encryption — payload encrypted with AI company's public key. Only they decrypt.
04IPFS + Solana CID — encrypted payload pinned to IPFS, hash stored on-chain permanently.
05Instant payment — Solana contract automatically pays contributor wallet on verified submission.
06AI company gets clean API — Alcor bridges to USD. No crypto on buyer's end.
