I build guardrails for people's money.

I'm a chemical engineer from Lagos. In 2026 I shipped 20+ products, most of them live onchain with real money in them.

01 Now building

Plinth

Savings on tokenized US stocks with a floor under them.

You deposit dollars, pick a stock and a floor. Part of the money rides the stock and the rest earns interest. When the stock falls, an agent moves money to safety on its own, at 3am on a Sunday if it has to.

Banks have sold this for decades as the capital protected note, with minimums, lockups and desks that only trade in New York hours. Plinth runs one contract per saver, from $1, with no lockup.

02 The ledger

Everything I shipped this year, still live.

16 products, strongest first. Open a row to see it. Every link goes to the real thing.

01 Tifo Your matchday sales, run by an agent. Arc mainnet

A shop puts its stock on a big match. Buyers get money back in USDC if their team wins, the contract caps what the shop can lose, and an agent runs the money inside a weekly limit. Buyers pay by card, bank transfer or naira.

02 Freeze Lock today's crypto price. Decide later. Arbitrum, in PayBox

Tell your AI agent to freeze today's BTC or ETH price for a small fee. If the price rises, the gain is yours. If it doesn't, all you lose is the fee.

03 Kept A trading wallet that keeps part of every win. Solana mainnet, Android

Every profitable sell banks a share of the profit into a vault with a slow way out, so a winning streak leaves something behind.

04 Floorline Protect your MON without selling it. Monad mainnet

Pay once to set a floor under your MON until a date you pick. If MON ends below it you are paid the difference, and you keep your coins and the upside. Fully backed and priced onchain.

Built forMonad Metropolis

Open Floorline Code

05 Breaker Halt protection for tokenized stocks. Solana

One call a trading venue adds, so halted stocks stop trading, daily limits hold and every trade is published.

06 Keel Borrow against your Bitcoin. Never redeemed. Mezo testnet

A strategy that plugs into Mezo's MUSD savings vault. It lends idle savings to Bitcoin holders outside redemptions, and the interest goes to savers.

07 Shunt See what could break your trade before you place it. Bitget

Say your trade in plain words. Shunt finds every earnings report, Fed decision and weekend inside your hold, and measures how far each one moves that exact stock.

08 RESIDUAL Trade only what belongs to the company. Bitget

Strips the market, the sector and the liquidity effect out of an earnings move, then trades only the part left. Tested out of sample across 46 companies, with the failed hypothesis published.

09 Safe Journal Write it down. Keep it safe. Make it count. Arkiv

A private journal for documenting abuse. Nothing stays on the phone, every entry's time can be checked by anyone, nobody can delete an entry, and a lawyer gets a read link.

10 Proof of Exploit Get paid for the bug. Never say who you are. Midnight

03 How I build

1
Test the risky part first

Before I build, I prove the one thing that could kill the idea, live, with real data. Plenty of ideas die at this step, and that's the point of it.
2
Ship to mainnet

Most of the ledger runs on mainnet with real money, because that's where the edge cases live.
3
Correct in public

When I found Plinth's backtest claim only held for the sample I had tested, I published the correction and then lowered five risk levels onchain.
4
Think like a process engineer

Chemical engineering is about keeping a system inside its limits while shocks hit it. Most of what I build is that loop, applied to money.

04 About

I'm Jennifer Eze.

I trained as a chemical engineer at Nnamdi Azikiwe University and did my industrial training in operations at the Warri refinery. In 2026 I started building software full time and haven't stopped: 20 hackathon entries this year, each one a real product.

I build for people like the ones around me in Lagos: people saving in dollars, trading on their phones and running small businesses.

Degree: B.Eng Chemical Engineering, Nnamdi Azikiwe University, 2026
Training: Operations, Warri Refining and Petrochemical Company (NNPC), 2025
