A Time Capsule Gift Mini-App built on the Base ecosystem.
Base Capsule lets you send time-locked crypto gifts to anyone on Base — gifts that stay sealed until the exact moment you choose. Whether it's a birthday surprise, a future milestone, or just a thoughtful gesture, your gift waits patiently on-chain until it's time.
🌐 Live App: basecapsule.space
📱 Base App: base.app/app/basecapsule.space
Send ETH or USDC to someone, locked until a future date and time you set. The recipient can't open it early — not even peek at your hidden message. When the moment arrives, the gift unlocks and they can claim it on-chain.
Inspired by the tradition of giving, Red Packets let you drop crypto rewards for multiple people at once. Create a shareable link, set a total pool, choose equal split or lucky draw — and let your friends race to claim their share.
💌 Hidden Messages
Every gift comes with a personal note that stays encrypted until unlock. Your words are part of the gift.
Recipients receive a unique NFT as proof of their gift — a digital keepsake that lives on Base forever.
Want to keep the mystery? Send anonymously and let the recipient wonder who cared enough to send.
No middlemen. No custodians. Everything runs on a smart contract deployed on Base Mainnet — trustless, transparent, and verifiable by anyone.
Send gifts directly to Base usernames like username.base.eth — no need to copy-paste wallet addresses.
