Show HN: Fundhog – A Ko-Fi Alternative for Accepting Crypto Donations

I’m thrilled to share Fundhog, a platform I built to let creators, developers, and nonprofits accept cryptocurrency donations directly. It’s like Ko-fi, but for Web3, supporting Ethereum, Polygon, and other EVM-compatible chains—with no middleman. Every transaction happens straight between the donor and creator.

Why FundHog?

Fiat platforms charge steep fees and limit access. Fundhog uses blockchain for direct, low-fee, transparent donations. Here’s the scoop: Button Builder: I added a simple tool so creators can design their own donation buttons. Pick size (small/medium/large), border radius, and colors to match your site, then grab the embed code.

No Middleman: Funds go directly from donor to creator. I don’t handle your crypto—Fundhog just connects wallets.

Easy Embedding: The ~1KB embed.js script adds your button to any site (HTML, React, etc.) in minutes.

Multi-Chain: Donors pay via MetaMask or similar on Ethereum, Polygon, and more. Chain detection ensures a smooth flow.

Secure: A lightweight iframe modal keeps transactions safe, with no heavy dependencies.

Use Cases Open-Source Devs: Fund your GitHub repos with ETH or MATIC tips.

Creators: Accept global crypto without platform cuts, styled your way.

Nonprofits: Raise funds transparently, wallet-to-wallet.

How It Works

Use the button builder to customize your look.
