HongBao
Physical cards that hand out crypto rewards at real events
What it does
Sending crypto to real people is harder than it should be. Run an airdrop and bots farm everything — most rewards end up in scripted wallets. Hongbao is a physical card that holds an on-chain reward. Hand it out at an event, the holder scans it, taps the button, and the reward lands in their wallet from a smart contract. No app signup, gas covered. Non-custodial, no admin keys, open contract.

- H6Homebrew 6.0.0▲1,481
Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
