There are Claude and ChatGPT tokens on dexdo now trading as low as 1 SHELL per tic (which is 1m tokens). I bet it won’t last long but… here I said it…

To bridge the intersection between Web3 and AI, I built a local automation system using ibm/granite4:3b-h and llama3.2:3b.
​The setup automatically:

[Samuel Mwanza @WanzaBlock_]

■ Classifies incoming emails & drafts replies
■ ​Extracts local work tasks on my machine
■ ​Generates social content
​Fully local, fast, and off-cloud.

Plus, strong performance on Fill-In-the-Middle and syntax tasks makes it a surprisingly viable offline coding assistant on Android.

IBM Granite 4 (1b-h / 3b-h) is quietly killing it for local mobile AI.
​The hybrid Mamba-2 + Transformer setup keeps RAM light and decoding fast on Termux + Ollama.

USB → Ollama → Qwen2.5-Coder 7B → Local API → WanzaBlock AI web UI

In 2026, using AI to protect your smart contracts is no longer a choice, it's a necessity.

[Samuel Mwanza @WanzaBlock_]

The EVM runs your smart contracts.
Every node executes the same bytecode → same result. That's determinism.
Solidity → Compiler → Bytecode → EVM
Know your execution environment.

[Samuel Mwanza @WanzaBlock_]

The best opportunities aren't about the technology.
They're about the problem that exists whether or not the technology does.
Find the problem first. The tech is just how you deliver the solution.

5/ Whether you're a web dev or a smart contract engineer, these two interfaces are the silent heroes keeping our digital world connected and functional.

1/ Ever wonder how your code actually talks to a computer or a blockchain? It’s all about the bridge between API and ABI. Here’s a 60-second breakdown.

[Samuel Mwanza @WanzaBlock_]

4/ Why does this matter? An API helps you build the app. An ABI helps the app execute on the hardware. Without the ABI, your software wouldn't know how to pass data to the system's memory.

[Samuel Mwanza @WanzaBlock_]

The System:
- 4 Roles: Manufacturer, Distributor, Regulator, & Consumer
-No passwords-just secure wallet logins
- Lightweight and fast design
- Built with Node.js and Vanilla JS
​The toughest part was making the "who-does-what" rules secure but simple. It’s nearly ready for use.

I’m building WanzaBlock to stop counterfeit medicines and farm supplies.
​The goal: Total transparency from the factory to the person buying the product.

Foundry is the best thing that happened to my Solidity workflow.
forge build, forge test, cast call, all done from the terminal.
Tests in Solidity, Super fast aswell
No config bloat.
