Crack My Code
Created on Jun 28, 2026
**Crack My Code** is a competitive code-cracking duel built on Celo. Two sides each hide a secret 4-digit code; whoever cracks the opponent’s code first wins.
Feedback on every guess is Wordle-style — green (correct digit, correct position), yellow (digit in code, wrong position), gray (not in code) — so every guess is a logic puzzle, not a coin flip.
The product is **live and playable today** in the browser and as a **Farcaster Mini App**. Players can:

Owo
Created on Jun 27, 2026
Owo is building Nigeria's circular G$ economy: a spend rail and peer-to-peer marketplace that lets GoodDollar claimers actually use their G$ to buy airtime, data, and electricity, pay local merchants, or trade with peers for Naira without G$ ever leaving the ecosystem.
Today hundreds of thousands of Nigerians claim G$ daily but have almost nowhere to spend it, so the token sits idle and its utility stalls.
Owo closes that gap with two connected surfaces:

Cairn is an open-source (AGPLv3) coordination layer for multi-agent AI systems.

On Celo, Cairn adds verifiability: every coordination run can emit an on-chain receipt and each agent carries an ERC-8004…
