Base has grown into one of the largest crypto networks, and now an everything app has been built around it. By pushing DeFi into its consumer era, Base has become a staple for new and experienced traders alike. And Matcha has been supporting from day one, with gasless swaps, instant discovery of brand new tokens, and cross chain swaps across the broader onchain ecosystem.

Gasless trades and approvals are a feature of Matcha Auto, so you can free up stuck funds and get on with your trades. It also executes faster, so you can mint quicker, and stay safe from sandwich attacks.

Make gasless swaps on Base, Ethereum, Arbitrum and 8 more chains.

What is Matcha Auto

Swapping tokens in with Matcha Auto disabled is free on Matcha, but you always need to have some native gas tokens in your wallet to pay for the transaction. Matcha Auto takes this friction out of the equation so you can move faster without worrying about gas, MEV, or other technical hurdles. 

Matcha Auto gives a whole new Web3 experience by leveraging intents or metatransactions. These are made possible by the 0x Gasless API built by Matcha's sister company 0x. By forwarding your swap request to 0x, you get to trade without gas through private channels for a more efficient experience with more competitive rates.

0x coordinates directly with private market makers, pays the gas for you, and then collects the fee back from the tokens you receive, so you never need to deal with gas again and get the same great rate you would if you used manual settings. 

The power of gasless trades

Gas fees are integral to crypto and won’t just disappear, if anything - they’ll get worse. Matcha Auto lets you abstract away the gas, so you don’t have to deal with it. This opens up new possibilities that make crypto more consumer-friendly. You can:

• Complete trades if you run out of Ether. 
• Make approvals at any time.
• Bridge tokens to a new network without a follow-up transaction to send gas. 

How Matcha Auto saves your crypto

Standard swaps on Matcha are free, but Matcha Auto is designed to make life easier, so there must be a catch, right? Actually, Matcha Auto can save you money, especially if you use it frequently. While there is a 0.25% cost for transactions made with Auto, there are several cost-saving benefits:

• Gas savings: no more dust gathered on every chain, no more gas-guzzling cross chain top-ups.
• MEV protection: MEV is a result of transaction inefficiencies and public mempools. Matcha Auto routes transactions in a way that improves execution through private market makers to save you money.
• Improved price execution: get more competitive pricing, lower slippage, and lower trade failure rates.  
• Faster confirmation: block ordering can leave you missing out on key trades, but Matcha Auto relays trades through privileged channels so they are more likely to get into the next block.

And all that for the same price you pay for regular, gassy trades with high revert rates on Uniswap!

No gas needed for approvals

Gasless trades are a key user experience improvement, but if you need gas to approve spending a token first, what’s the point? Matcha Auto makes approvals gasless, too! So if you’ve just sent some USDC to Base, you’re best going to Matcha to approve and spend your crypto in one go, without the friction.

What is Base network?

Base is a Layer-2 EVM network that was incubated by Coinbase. Using optimistic rollups, it monitors the Ethereum network state and processes transactions offchain, achieving lower gas fees while still inheriting much of Ethereum’s security. 

Base began occupying fast-growing niches of Web3, with integrations on many major platforms accompanied by a growth focus on apps such as Farcaster, where Base had been an early adopter of Frames technology and a prominent supporter of hackathons, alongside Coinbase Wallet. 

So if you're ready to speedrun Farcaster culture, you can now stock up on Degen tokens, Noice, and everything in between using USDC.

What about gas on other chains?

Matcha Auto is on most chains already. But if you’re out of gas on one of the networks where Matcha Auto is not yet available, you can easily top up on gas using a cross chain swap. Matcha’s bridge aggregation makes it affordable and fast to move your gas token to a new chain and unblock your trades. Don’t get stranded with tokens you can’t move, start using Matcha today!
