Shake Defi

Secure crypto payments with smart-contract escrow for buyers and sellers

Shake Defi – Safe Crypto Payments With Smart-Contract Escrow

Shake Defi makes cryptocurrency usable in the real world by giving buyers and sellers a safe, simple, and secure way to transact. Whether you're buying a car, hiring a contractor, or paying for goods and services, Shake Defi protects both parties with an automated escrow that runs on the blockchain.

Traditional escrows are expensive, slow, and require banks or certified intermediaries. Shake Defi replaces all of that with a smart contract – an autonomous program that holds funds, enforces rules, and ensures fair outcomes. No banks, no middlemen, no business hours.

How It Works
• Buyer and seller agree on an escrow duration (0–180 days)
• Funds are locked in a smart contract on the Ethereum Base network
• The seller delivers the product or service
• After the escrow period ends, the seller collects payment via the app
• If there's an issue, the buyer can open a dispute and request a refund. Or, the seller may issue a refund outside of a dispute
• If approved, the smart contract automatically returns funds to the buyer

Easy Crypto Payments – Even If You're New to Crypto

Shake Defi is designed to feel as safe and familiar as a credit card payment – without high fees or chargeback fraud.

You can transact using stablecoins like USDC or native ETH, depending on your needs.

If you don't already own crypto, Shake Defi lets you buy and sell it directly inside the app:
• Buy crypto (Onramp): Purchase USDC or ETH using a bank account or debit card
• Sell crypto (Offramp): Convert crypto back to U.S. dollars and withdraw to your bank

All crypto buying and selling is handled by Coinbase, a trusted, regulated U.S. financial platform. Shake Defi never processes or stores your fiat money.

Pay With Any Supported Cryptocurrency

Shake Defi supports flexible payment options through integrated currency swapping. If a merchant requests USDC or ETH, you can pay using Bitcoin, Cardano, Dogecoin, Litecoin, XRP, or Staked ETH. Transfer your cryptocurrency to your Coinbase wallet in the app, and it will automatically convert to the required currency using Odos, a decentralized exchange aggregator. Merchants can now accept crypto from anyone.

Note: Coinbase and Odos swap services are not available in all countries.
