Overview

The what, why, and how of CoinTap

Bitcoin's Promise, Actually Delivered

CoinTap is cryptocurrency backed by real precious metal you can physically hold. Buy it, sell it, trade it—all digitally—while the actual silver or gold stays in your possession or a vault of your choosing.

01

The Problem with Precious Metals Today

  • Hard to sell. Finding a buyer means visiting dealers, negotiating, and often accepting below-market prices.
  • Hard to verify. Is that bar real? You need expensive assays or trust the seller.
  • Hard to trade. Shipping physical metal is slow, risky, and expensive.
  • Easy to fake. Counterfeits are everywhere. Tungsten-filled bars pass basic tests.

The result? People avoid precious metals, or buy "paper gold" that's just a promise from a bank.

02

What CoinTap Changes

  • Sell digitally, instantly. List your coin on the marketplace. Buyer pays. You ship or they pick up. Done.
  • Verify with your phone. Tap the coin. Cryptographic proof in 2 seconds. No experts needed.
  • Trade globally. Ownership transfers on-chain. The coin can change hands anywhere in the world.
  • Impossible to fake. Each chip has a unique key that can't be copied. Destroy the chip, destroy the value.
03

How It Actually Works

Every CoinTap has an NFC chip embedded inside the metal. This chip contains a cryptographic private key that:

  • Can never be extracted or duplicated
  • Signs a unique challenge every time you tap it
  • Links to a blockchain record of the coin's specs and current owner
  • Protected by EAL6+ certified hardware—the same security level used in banking cards and passports

When you buy a CoinTap, you get the physical coin AND blockchain ownership. When you sell, the buyer verifies the coin, pays into escrow, you transfer ownership with a tap, and funds release automatically.

04

You Decide How to Store It

  • Hold it yourself. Keep your coins at home, in a safe, wherever you want. True self-custody.
  • Use a vault. Partner vaults can store your coins securely. You still own them on-chain.
  • Trade without moving it. Coins in vaults can change ownership without physical shipping.

Your metal, your choice. No one can freeze your account or deny you access.

05

Beautiful, Collectible Designs

CoinTaps aren't generic bullion rounds. Each release features original artwork, precision minting, and limited editions. They're investments AND collectibles—coins you'll actually want to own and display.

Think of it as the intersection of numismatics, precious metals, and crypto.

Questions

Hold your phone near the coin. The NFC chip sends a cryptographic signature that proves authenticity and shows current ownership—takes about 2 seconds.
No. Each chip has a unique ID and private key that can't be extracted. The chip signs challenges cryptographically—without the key, signatures can't be faked.
No. The coins are real metal you can hold. The blockchain is there when you want to prove or transfer ownership, but it's completely optional.
Buyer pays into a smart contract. A time window opens where only you can transfer to that buyer. Tap your coin to confirm—ownership transfers and you receive payment automatically.
Marketplace: 2% (seller pays). Blockchain gas: fractions of a cent. Verification: always free.
