Nerdjango Labs builds the payment, blockchain, and AI systems a business runs on, plus the web and mobile products around them.
We are the software engineering agency of Nerdjango Limited and the team behind Planbok.
Payments, keys, and the processes teams still run by hand. That is where we do our best work.

Where we go deepest
Payments and Smart Contract Development. These two are where our strongest work lives.
Payments
We build the layer above the providers: one API, routing that survives a provider going down, and a ledger that reconciles.
Two modes, one discipline
- Payment orchestration
- Cross-border corridors
Nerdjango builds payment software for licensed operators, who keep their licence, merchant contracts, and funds.
Cross-border corridors are named as NGN, GHS, KES, and ZAR, alongside multi-chain onchain rails.
Planbok's wallet infrastructure supports 40+ chains, and the runtime truth for a given environment is GET /v2/tokens/metadata.
Smart Contract Development
Solidity and onchain contract work, with a review pass over every contract before it ships.
What the work covers
- Contract development
- Security review
- Chains supported by Planbok
- 40+Runtime truth: GET /v2/tokens/metadata
- Cross-border corridors named
- 4NGN, GHS, KES, ZAR
Seven Services
Five development disciplines, plus Management & Optimization and Consultation for the work that comes before a build and after a launch. Each has its own page.
Web development
Web products that hold up under real traffic.
Mobile development
One codebase, two app stores, no drift.
Blockchain development
Contracts written, then reviewed before they ship.
AI development
Automation, agents, and models inside the product you already run.
Payments
Orchestration above providers, and cross-border corridors.
Management & Optimization
We keep what you already run fast, current, and able to take more.
Consultation
A second opinion before you commit the team.
Planbok
Planbok is programmable wallet infrastructure with built-in rails for stablecoin and fiat. We built it, we run it in production, and it is where most of what we know about wallets came from.
Planbok is non-custodial in one specific sense: a private key is never fully constructed, so no single party can sign alone. That is a statement about key material, not about who holds fiat.
Questions we get asked
The four things we get asked most, answered in a sentence each.
Which African payment corridors do you build for?
We build cross-border payment software for the NGN, GHS, KES, and ZAR corridors, together with multi-chain onchain rails.
Do you work onchain as well as on fiat rails?
We build onchain rails alongside fiat flows, and the chains behind them come from GET /v2/tokens/metadata rather than from a published list.
How do you handle smart contract security?
Every contract we write gets a review pass before it is deployed, and that review is part of the engagement rather than a separate purchase.
What does AI work with you start with?
AI work usually starts with workflow automation, then moves to agents and LLM integration into existing products once the process is understood.
Tell us what you are building
Five short steps and we know what you need. The first reply comes back specific, not with a request for a call.
