0x review 2026 — wallet-signed DEX swaps on SwapZilla
0x is a DEX aggregator that finds the best-priced route across on-chain liquidity and hands it back as a transaction your own wallet signs. No account, no deposit address, 26 EVM networks.
What is 0x?
0x has been building on-chain trading infrastructure since 2017 and today powers swap features in wallets and apps across the industry. It is not an exchange that holds your coins: it reads the order books of automated market makers — Uniswap, Curve, PancakeSwap, Aerodrome, DODO and dozens more — splits your trade across whichever pools give the best price, and returns a ready transaction.
That makes it a different animal from every other provider on SwapZilla. The exchangers here take your coins at a deposit address and pay out from their own float. 0x never touches your coins at all: they move from your wallet straight into the DEX contract in a single transaction that you sign yourself.

Pros & cons
Pros
- Your coins never sit with a third party — no deposit address at all
- Best price across dozens of pools, chosen per trade
- No account, no KYC, no e-mail
- Settles in about a minute, in one transaction
- A guaranteed minimum output is written into the transaction itself
Cons
- Needs an EVM wallet such as MetaMask — this is not a send-and-forget swap
- Both coins must live on the same network: no cross-chain routes
- You pay network gas yourself, which hurts on small amounts
- ERC-20 tokens need an approval transaction first
How to swap via 0x on SwapZilla
- Open the SwapZilla calculator and pick two coins on the same EVM network — say ETH and USDC on Ethereum, or USDC and WETH on Base.
- Enter the amount. SwapZilla asks every provider at once, 0x among them, and shows the routes side by side.
- If 0x has the best rate, select its card. The button turns into Connect wallet.
- Connect your wallet. The route is rebuilt for your address, and the button becomes Swap from your wallet.
- Confirm in the wallet — an approval first if you are selling a token, then the swap. The coins arrive in the same wallet a block later.
Fees
The number you see in the calculator is what lands in your wallet: SwapZilla's 0.3% service fee and 0x's own protocol fee are already inside it. On top of that you pay the network's gas, which the wallet quotes before you sign — that is paid to the blockchain, not to us.
SwapZilla verdict
If you already hold your coins in an EVM wallet and both sides of the trade live on the same network, 0x is usually the cleanest way to swap them: nobody takes custody, nothing is queued behind an exchanger's float, and the whole thing is over in a block. For cross-chain moves, or if you would rather just send coins to an address and walk away, the custodial providers on SwapZilla are still the answer.
