Bit Primitive is an AI and data software company from Cape Town. We design, build and run products end to end: the pipelines that collect data, the warehouses that organise it, the AI that learns from it, and the apps people use every day.

What we do

• AI products: Models that train on your own data, local AI studios and design tools, and answers that always cite their source.
• Data engineering: Raw data collected, decoded and modelled into clean, documented, tested tables in a warehouse you own.
• Apps on live data: Consumer apps that turn public data into plain answers and timely alerts, on the phone, the web and Telegram.
• Web3 and developer tools: Crypto moves explained, forecast and alerted on, and tools that show developers exactly what their AI is doing.

Estate Box. AI built in.

A small, self-hosted box that brings your statements, exchange activity and market feeds into a warehouse you own, and runs an AI brain that trains on that data every night. It packages Data Estate, the reference build that runs daily on a Raspberry Pi.

• Trains on your data: Models are trained from scratch on the box itself. No downloaded weights, no external AI service.
• Champion and challenger: Each night a new version competes with the current one on held-out data, and wins its place or is dropped.
• Forecasts that are graded: Every forecast has a range and is scored against what really happened once the date arrives.
• Answers with sources: Ask in plain words. Answers come from facts in your warehouse, with their source. It never invents a number.

Every night, on the box

1. Collect new statements and feeds
2. Rebuild and test the warehouse, then swap it in
3. Train a challenger for every model
4. Score it against the champion on unseen data
5. Promote only what measurably wins
6. Publish forecasts, insights and answers to your phone

Tap & Tank. Water and fuel, answered.

A consumer app for South Africa that answers three everyday questions from official public sources, starting in the Western Cape with more than a thousand areas: every City of Cape Town suburb and ward, plus the towns of the province's other municipalities.

• Water outages: When is the water off in my area, and when does it come back? Planned and unplanned outages from municipal sources, with their status as it changes.
• Dam levels: How full are the dams that supply me, and how long will they last? Your area linked to its dams: level, trend, last year, and a clearly labelled estimate of days of storage.
• Fuel prices: What will petrol and diesel cost next month? The official monthly price for your zone, plus a next-month direction, always labelled as an estimate.

• Restriction levels per municipality, in plain words
• Alerts by push notification or Telegram
• Every figure shown with its source and date
• Installable web app first, then iOS and Android

How we build

1. Collect (cryo · dlt · APIs): From statements, exchanges, blockchains, news and public data sources, through their own APIs, gently and within their terms.
2. Organise (dbt · DuckDB · Postgres): Into documented tables with tested keys and joins, in a warehouse on your own machine, server or box.
3. Learn (self-training models): Models trained on your own data, retrained as it grows, and promoted only when they beat the current version on data they have never seen.
4. Answer (apps · SQL · open data): Forecasts with ranges, alerts and plain-language answers on your phone, SQL for the deep dive, and open datasets anyone can use.

Public data

• Base ERC-20 transfers (100-block sample): Every ERC-20 Transfer event in 100 consecutive Base mainnet blocks, decoded, with each token's symbol, name and decimals joined in.
• Bitcoin transaction outputs (3-block sample): Every output of every transaction in 3 consecutive Bitcoin blocks: who received how much, the output's script type, and the sender when every input came from a single address. OP_RETURN and other outputs without an address are kept, with no address.
• ERC-20 token directory (Ethereum and Base): Every ERC-20 contract seen in the Ethereum and Base transfer samples, with the name, symbol and decimals it reports and how many transfers it had. Useful for decoding amounts.
• Ethereum ERC-20 transfers (200-block sample): Every ERC-20 Transfer event in 200 consecutive Ethereum mainnet blocks, decoded, with each token's symbol, name and decimals joined in. A sample of what chainstar produces from a single command.
• Ethereum transaction fees (200-block sample): The execution fee of every transaction in the same 200 Ethereum blocks: gas used, the price paid and the base fee, in wei and in ETH. Blob fees are not included.
• Solana DEX swaps (300-slot sample): Every swap in 300 consecutive Solana slots through Raydium, Orca Whirlpool, Meteora DLMM, Jupiter, Pump.fun or PumpSwap: what the signer gave and got, with a USD value from prices derived from the same on-chain swaps.
• Solana token and SOL transfers (20-slot sample): Every SPL, Token-2022 and native SOL transfer in the successful transactions of 20 consecutive Solana slots, inner instructions included, with each mint's standard and decimals.
• Solana token prices from on-chain swaps (300-slot sample): Hourly and daily USD prices for every Solana mint traded in the same 300 slots, derived only from on-chain swaps against USD stablecoins and SOL: outliers rejected, each price with its method, observations, volume and confidence. Low-confidence prices are left NULL, with the observed median kept.
