Just a reminder: CosmWasm is the heartbeat of Cosmos! With 100 chains (over 90% of the ecosystem) using it and 1.77M downloads of the standard library, it’s clear: #CosmWasm is THE go-to for smart contracts. When everyone’s using it, you know it’s gotta be next-level.🔥🚀

/3 💸 Transfer callbacks that actually help.
 3.0 adds a transfer field so you instantly know who sent what over IBC — no more parsing raw packets like it’s 2022.

🎂CosmWasm just turned 6 — that’s like… 42 in #blockchain years. From "hello world" contracts to powering real interchain apps, we’ve come a long way. Still #Wasm. Still spicy. Still cooking. Happy Birthday to the smart contract king of @cosmos.👑
