Tap-to-Tip

Tap-to-Tip turns any QR/NFC sticker or link into a one-tap crypto tip jar. Scan → set amount → send. No wallet popups, no seed phrases, no gas pain—thanks to MetaMask Delegation Toolkit + Embedded Wallets. Recipients get money instantly; you get analytics and optional platform fees out of the box.

The problem

Tipping creators, street vendors, streamers, and non-profits is still slow and leaky:

• Too many steps (connect wallet, confirm, sign, pay gas).

• Casual tippers bounce; small tips get killed by friction.

• Recipients lack clean analytics + payout controls.

The solution

A “scan → send” flow that feels like Web2:

• Web2-style login (MetaMask Web3Auth Embedded Wallets).

• Authorize once: user grants a narrow, time-boxed delegation.

• Frictionless sends: our delegate EOA executes tips on their behalf (we fund gas or sponsor later with a paymaster).

• Clean on-chain events via your TipJar so Envio can power dashboards, leaderboards, receipts.

Prime use cases

• Street sellers / cafés / pop-ups: QR at checkout or table tents.

• Creators/streamers: overlay QR; shout-outs per tip.

• Events & booths: QR sticker for quick tips, no cash handling.

How it works (simple)

1. Scan QR → tip page opens with ?to=recipient.

2. Login once (Embedded Wallets) → create delegator smart account.

3. Authorize once (30-day, function-scoped, optional recipient pin).

4. Tip anytime: our delegate EOA sends one tx to DelegationManager to redeem the stored delegation + call TipJar.tipTo(to, ref) with value.

5. Analytics: Tipped event → Envio → dashboard/CSV/webhook.
