Secure Payments With Smart-Contract Escrow
Buy and sell with payment terms both sides agree to.
Shake DeFi provides non-custodial payment escrow for commercial and direct transactions. Agree on the transaction, lock the payment in a smart contract on Base, and release the funds according to the agreed escrow terms.
Payment Escrow for Real-World Transactions
Buying a vehicle, sourcing bulk commodities, purchasing equipment, hiring a contractor, or selling goods?
Shake gives buyers and sellers a structured way to transact without sending payment directly to the other party.
You choose the escrow duration, agree to the transaction terms, and fund the smart contract. The payment remains locked while the transaction is completed.
How It Works
Agree on the transaction
The buyer and seller agree on the item or service, price, escrow duration, and other transaction terms.
Fund the escrow
The buyer sends the agreed payment to the Shake smart contract.
Shake supports USDC and USDT, as well as other supported cryptocurrencies including ETH and TON. Additional assets may be available through supported currency-swapping features.
Complete the transaction
The seller delivers the goods or services while the payment remains locked according to the agreed escrow terms.
Release the payment
When the applicable escrow period and release conditions are satisfied, the payment is released to the seller according to the smart contract rules.
Dispute when necessary
If the transaction does not go as agreed, the buyer can request a refund during the applicable dispute period. Shake's human review process evaluates the available transaction evidence and processes the outcome according to the escrow rules.
Non-Custodial by Design
Shake does not take custody of escrowed customer funds.
Your payment is held by a smart contract on the Base network rather than in a Shake-controlled account. The smart contract defines the conditions under which funds can be released or returned.
You use your connected wallet to authorize transactions.
Use the Cryptocurrency You Already Have
Shake supports USDC and USDT, along with ETH, TON, and other supported cryptocurrencies.
The seller can specify the cryptocurrency they want to receive. Where supported, buyers can use integrated currency-swapping functionality to convert another supported cryptocurrency into the required payment currency.
Shake is designed around cryptocurrency payments, but you do not need investment expertise to understand the basic transaction process: agree on terms, fund the escrow, complete the transaction, and release the payment according to those terms.
Optional Fiat Conversion
On supported mobile platforms and in eligible locations, Coinbase provides optional fiat onramp and offramp services.
You can use Coinbase to purchase supported cryptocurrency using available payment methods or convert cryptocurrency back to fiat.
Shake does not hold your fiat money or operate the Coinbase conversion service. Coinbase availability, supported assets, payment methods, and fees vary by country.
Transparent Fees
Shake charges 0.1%–1.0% for escrow transactions depending on the release option selected.
The standard service fee is 0.1%. Additional fees may apply when a merchant chooses an early withdrawal option.
Blockchain network fees may also apply. Third-party services such as cryptocurrency conversion and swapping may have their own fees.
Identity and Transaction Records
Shake uses identity verification to establish accountability between transaction participants.
Each transaction can include a signed agreement, transaction details, supporting documentation, and on-chain payment records.
For disputed transactions, a human reviewer evaluates the available evidence.
Built for Real-World Commerce
Shake can be used for transactions involving:
Vehicles
Buy and sell vehicles with agreed payment terms.
Commodities & Wholesale
Secure high-value orders, raw materials, wholesale goods, and commercial bulk supply.
Marketplace Goods
Add escrow to purchases originating from online marketplaces and direct commerce.
Services
Use payment escrow when hiring contractors, freelancers, or other service providers.
Other Transactions
Create an escrow transaction whenever both parties want payment held according to agreed terms.
Payment Service, Not an Investment Product
Shake DeFi is a payment and escrow service. It is not an investment platform and does not offer investment products or investment advice.
Cryptocurrency is used as the payment method for transactions.
Your Payment. Your Terms. Your Escrow.
Create a Shake transaction and give both sides a clear payment process backed by smart-contract escrow.
