Adds a 💸 Tip button to every tweet on X. Click it to open arcpay.finance, sign in, and send USDC on Arc. 2% fee, no KYC. ArcPay adds a 💸 Tip button under every post on X. See a take you like? Click the button and send the author USDC in seconds — no new account, no KYC, no "follow us" pop-ups. ━━━ How it works ━━━ 1. Install the extension and pin it to your toolbar. 2. Visit x.com. Every post now has a 💸 Tip button next to reply / retweet. 3. Click it. A small window opens on arcpay.finance. 4. Sign in with email or wallet, pick an amount ($1 / $5 / $10 / custom), and send USDC. 5. The transaction settles on Arc Network in under a second. 6. The creator gets the USDC directly in their wallet. That's it. ━━━ Why Arc ━━━ Arc is Circle's stablecoin-native L1. Built for USDC — fees are sub-cent, finality is under a second, and there is no separate gas token. No bridges, no "wrong network" errors. ━━━ What makes it different ━━━ • Email login via Privy — creators don't need an existing wallet. One is created for them behind the scenes, and the key can be exported anytime. • 2% flat protocol fee on tips. No hidden spread, no gas passed to the tipper. • Non-custodial — your keys stay in your wallet (or your embedded Privy wallet). ArcPay never holds funds. • Works with MetaMask, Rabby, Coinbase Wallet, and any standard EIP-6963 wallet. • If the recipient doesn't have a registered wallet or handle yet, the tip is held on-chain keyed by their X handle. They can claim it later via X OAuth. ━━━ Privacy & permissions ━━━ The extension only runs on x.com and twitter.com. It reads the handle shown on the post to route the tip. It never reads your DMs, your timeline, or anything else. No analytics, no tracking. Full privacy policy at https://arcpay.finance/privacy. ━━━ Who this is for ━━━ • Readers who want to pay creators in a currency that actually settles • Creators tired of Stripe's 7-day holds and 2.9% + $0.30 per charge • Anyone on X who's ever wished tipping wasn't 12 clicks deep on another platform Built for the lablab.ai "Agentic Economy on Arc" hackathon.
