Powered by 0x Protocol
Blanket DEX uses 0x Protocol, one of the most trusted and widely-used decentralized exchange infrastructure providers in the DeFi ecosystem.
🔍 What is 0x?
0x is an open protocol that enables the peer-to-peer exchange of tokens on the Ethereum blockchain. It acts as a liquidity aggregator, searching across dozens of decentralized exchanges to find you the best possible price.
🌊 Liquidity Aggregation
Instead of relying on a single DEX, 0x checks multiple sources including:
- Uniswap V2 & V3
- SushiSwap
- Curve Finance
- Balancer
- And 70+ other liquidity sources
💰 Better Prices
By splitting your order across multiple DEXs, 0x can often get you better rates than trading on a single exchange. The protocol automatically finds the most efficient route for your swap.
⚡ Gas Optimization
0x's smart routing minimizes gas costs while maximizing price efficiency. You get professional-grade execution without paying enterprise fees.
🔒 Security & Trust
0x Protocol has been audited multiple times by leading security firms and has facilitated over $100+ billion in trading volume since launch. Your swaps are executed through battle-tested smart contracts.

❓ Frequently Asked Questions
Do I need a wallet to use the DEX?
Yes, you need a Web3 wallet like MetaMask, Coinbase Wallet, or WalletConnect-compatible wallets. For buying crypto, you can send it to any Ethereum address.
What networks are supported?
Currently, Blanket DEX supports Ethereum mainnet, with plans to add more networks soon.
Why do I need to approve tokens before swapping?
Token approval is a security feature that allows the smart contract to access only the specific amount of tokens you want to swap. This is a one-time action per token.
Can I cancel a transaction?
Once confirmed on the blockchain, transactions cannot be reversed. Always double-check details before confirming. If your transaction is pending, you may be able to speed it up or cancel it through your wallet.
What if my swap transaction fails?
Failed transactions can happen due to slippage, insufficient gas, or network congestion. You'll only pay gas fees for failed transactions. Try adjusting slippage tolerance or increasing gas fees.
