ChainGreets

ChainGreets started as a simple idea while exploring different Web3 ecosystems.

Over the past months, I've been interacting with several networks — MegaETH, Soneium, Robinhood Chain, Arc, Tempo — testing faucets, bridges, wallets, and transactions across these environments. That process made me realize something interesting:

I am not a professional developer. I'm someone passionate about technology, crypto, and learning how things work. So instead of only interacting with existing dApps, I decided to build a small project where I could experiment with different aspects of Web3 development.

ChainGreets is that project. It's essentially a personal playground to learn by building and interacting onchain.

The project is also heavily supported by AI-assisted development tools, which help explore ideas, write code, debug problems, and move faster when experimenting.

Another inspiration came from simple social dApps like OnChainGM and ZNS Connect — applications showing that even the simplest interactions, like saying GM, can become engaging when recorded onchain. ChainGreets builds on this idea while focusing on experimentation, learning, and multi-chain exploration.

At its core, ChainGreets enables a very simple interaction: sending a GM or GN message onchain.

In the first version, this works through a transaction where the message is encoded directly in the transaction data:

Most experiments are currently performed on testnets, allowing safe experimentation with different networks. A very small optional fee may be added on some mainnet interactions to support development and infrastructure costs.

Beyond sending GM or GN messages, ChainGreets is also an experiment in:
