Blockchain SACCO

DeFi

In developing countries, many people use loan circles because they cannot access/afford formal banking services. In Kenya, these loan circles go by the name of Savings and Credit Co-operative (SACCO). These organizations have about 9 bn USD in assets and about two-thirds of Kenya's population benefits from them. However, fraud is a well-documented problem in these institutions. Accordingly, I want to use blockchain to enhance transparency and enforce governance in SACCOs.

BlockDB- worlds best DeFi datasets. Tick-by-tick, auditable, one schema.

DeFi

BlockDB is the most detailed DeFi data infrastructure in the world. Only we offer proof-of-derivation: every row is cryptographically linked to the exact on-chain event that produced it — no other provider can do this. Tick-by-tick granularity, where competition only offers aggregated "candlesticks". Every dataset is deterministic and fully reproducible from genesis to today. Our infrastructure is production-ready to deliver on Solana.

BlockFlip

Real World Assets (RWA)

BlockFlip is a decentralized RWA protocol on Solana that tokenizes the property flipping cycle. We enable investors to fund the acquisition and renovation of distressed real estate using USDC, sharing the profits upon sale.

No crypto jargon. No wallet addresses. Just trust, post, and transact, the way blockchain should have always worked.

Blockline

Developer Infrastructure

Blockline is the MEV intelligence platform for Solana. It exposes sandwich attacks, write-lock contention, and validator↔wallet correlation through an API and a PoH-tick-precision timeline, turning the noise of Solana's mempool competition into actionable signal for MEV teams, market makers, and protocol researchers. Used in production by paying customers today.

Blockpeek

Consumer Apps

Blockpeek is a consumer-facing tool that simplifies blockchain data for everyday users. Instead of requiring users to understand complex explorers, it translates raw on-chain data into simple, readable insights.

BORE.OIL tokenizes real oil royalties on Solana — built natively on the Solana Developer Platform (SDP). Backed by a partnership with a publicly listed TSXV oil producer holding royalties on producing oil wells. BORE.OIL leverages SDP's Issuance Module to mint fully compliant, oil-backed tokens. Each token represents a direct claim on real production royalty revenue not a synthetic, not a derivative, not a wrapper. Real barrels. Real cash flow.
