⏳ Day 10/60 Building SafePay

A long, good day: half research, half code.

I studied 4 Ethiopian payment gateways (Chapa, ArifPay, SantimPay, AddisPay) and found they differ on test access, cancelling, webhook security, and status names. So I built a universal adapter framework that lets SafePay plug into any of them, and moved the provider's own details (reference IDs, raw status) into new database fields.

I also added a verify-before-trust rule: a webhook never decides a payment's status, SafePay asks the provider to confirm first. To test it without real money, I built an in-memory fake provider, and the automated tests pass.

Next: connecting Chapa in test mode.

Good morning everyone 😊😊

Have a Good Day❤️❤️

I built Fayda MCP, a Python library for connecting AI agents to Fayda eSignet identity verification.

• Start verification and track its status.
• Retrieve identity and age-check results.

pip install fayda-mcp

If you find it useful, give the repo a star!⭐️

@Atomic_izzy

Really cool project 👏👏

⏳ Day 11/60 Building SafePay

The most exciting day so far: SafePay talked to a real payment gateway.

I built the first real adapter, for Chapa, in test mode with no real money. SafePay creates a Chapa checkout page, I paid with a Chapa test card, and SafePay asked Chapa what happened and translated the answer into its own status, going from pending to succeeded.

Next: checkout sessions, so a merchant can start a Chapa payment through SafePay's own API.

Good 🌃 night 🌙 fams

Getting a job is the new "you won an iPhone 13 pro" scam 😁🤣

⏳ Day 12/60 Building SafePay

Today SafePay got its front door: a checkout session endpoint. A merchant sends an amount and an invoice number, SafePay asks Chapa to create a payment page, and the merchant gets the link back. The request needs an Idempotency-Key, so if a merchant retries, SafePay returns the same session and never creates a duplicate payment or calls Chapa twice.

Next: reading the real result from Chapa and updating the payment's status.

👀Something big is Coming👀🤯🤯

Good morning everyone ☺️❤️

Have a good Saturday ☺️☺️❤️

⏳ Day 13/60 Building SafePay

The customer paid, but does SafePay know?

Today SafePay learned to ask Chapa what really happened. When a merchant checks a payment, SafePay verifies it with the provider, then moves it through its states, pending to processing to succeeded, with a history row for each step, and sends the merchant one signed webhook.

Checking again changes nothing and sends nothing twice. The status comes only from Chapa's own answer, never from a browser redirect or an unverified message.

Next: receiving Chapa's own webhooks safely.

Announcing Vitra v0.2.3: The Universal Visual Runtime & Spatial Version Control Engine

I built Vitra, an open-source visual runtime, deterministic layout engine, and spatial version control system. It formalizes UI design into an open Visual Abstract Syntax Tree (AST), provides a Git-compatible content-addressable object store for user interfaces, maintains bidirectional real-time synchronization with Penpot and Figma, and exposes a native Model Context Protocol (MCP) server enabling autonomous AI agents to inspect, audit, build, and version software interfaces with mathematical precision.

Key Features

- Deterministic Visual AST & Object Store: Typed, immutable scene nodes with spatial layout metrics, typography, and fills, backed by a content-addressable DAG using SHA-1 object hashing and zlib-compressed trees.

- True Spatial Version Control: Full Git semantics for design files (init, add, commit, log, branch, checkout, merge). Features a true 3-way AST merge engine that automatically resolves non-overlapping structural and property changes.

- Embedded Web Studio & Zero-Dependency CLI: Single standalone native executable compiled with Bun. Serves an interactive canvas web studio and sync server directly from binary memory with zero external assets required on disk.

- Bidirectional Penpot & Figma(experimental) Live Sync: Seamless bridge connecting open design tools to code repos. Includes a hosted Penpot plugin with millisecond WebSocket synchronization directly mirroring canvas edits into your local AST.

- Headless Quality & WCAG Auditing: Automated continuous integration engine calculating WCAG 2.1 AA/AAA contrast ratios, geometry boundary overflows, and minimum touch target surface validations.

- Multi-Target Production Code Generation: Transpiles the Visual AST directly into idiomatic React with Tailwind utility classes, native Apple SwiftUI view hierarchies, and semantic HTML5/CSS.

- Zero-Dependency Bitmap & Vector Export: Headless vectorization pipeline compiling text to mathematical SVG paths, rasterizing pixel-perfect PNGs via an embedded WebAssembly engine without requiring external system font libraries or npm dependencies.

- AI-Native Model Context Protocol (MCP): 20 native JSON-RPC tools and pre-packaged agent skills installable directly into Claude Desktop, Cursor, and Antigravity (npx skills add ruhamabek/Vitra) for autonomous interface engineering.

Core Tech Stack

TypeScript, Bun, Yoga Layout, W3C Design Tokens, WebAssembly, OpenType, Resvg(Rust) , WebSocket, Lucide, React, Tailwind CSS, Model Context Protocol (MCP).

⏳ Day 14/60 Building SafePay

SafePay can now receive Chapa's own webhooks.

Today SafePay got its own door for Chapa's webhooks, which means a public endpoint anyone can knock on, so security came first. Every request must carry a valid signature, or it is rejected with a 401 and logged in an audit table that stores only a hash of the body.

Even a correctly signed message that says "paid" cannot change a payment, because SafePay always asks Chapa directly what really happened and updates from that answer.

Next: reconciliation, so SafePay catches payments whose webhook never arrived.
