However, some exchanges that advertise as non-custodial take control of your crypto during specific parts of trade execution. When creating this list, we put each exchange through a battery of tests and identified which ones are truly non-custodial.
In this guide, we’ll go over what a non-custodial exchange is, its pros and cons, and how to pick the best one for your needs.

A non-custodial crypto exchange is a platform where you can trade while maintaining control over your crypto throughout the process.
The most popular crypto exchanges are custodial, meaning you deposit your funds into the exchange’s wallet. This leaves you vulnerable to the exchange being hacked or acting maliciously, as the saying goes, “not your keys, not your crypto.”
A non-custodial exchange, on the other hand, never holds your funds itself. Instead, you connect your wallet and sign off on every transaction yourself before it’s executed directly on-chain. However, this also means that you are responsible for your own security and gas fees.
Architecture models differ between non-custodial exchanges. There are two main ones:
There’s no one-size-fits-all non-custodial exchange. Instead, you should take a close look at a variety of factors and prioritize them according to your needs. Let’s take a look at the most important ones.
The non-custodial umbrella encompasses three main custody models, with varying degrees of adherence to self-custody.
All of the features in the world won’t matter if your non-custodial exchange doesn’t support your wallet. For traders or investors with their funds split across wallets, the number of supported types tends to matter more. Look for WalletConnect support and integration with hardware wallets, along with a large number of supported wallets.
Beyond a baseline level of support, look at integration quality. If you’re using multiple browser-extension wallets, you’ll want EIP-6963 functionality to avoid entanglement. Similarly, if you’re using a hardware wallet, use an exchange that supports clear signing.
What chains a non-custodial trading platform supports determines what you can trade. The more chains are available, the more asset variety you’ll be able to take advantage of. If you’re interested in a small, up-and-coming blockchain, there may only be a few exchanges supporting it.
Cross-chain support can be one of the biggest boons, simplifying trading and increasing liquidity. Here, it’s important to check whether the cross-chain support is native or routes your trades via a 3rd-party bridge. With the latter, you’ll need to keep in mind that the 3rd party has its own risk profile, so you should always verify it’s trustworthy.
Issues with the exchange’s underlying smart contracts are the only source of exchange-side risk when using a non-custodial exchange. If malicious actors find a vulnerability in the code, you could be left with no funds and no way to recover them.
Independent audits of the smart contracts help mitigate this by verifying that the code is secure and safe. Ideally, the smart contract is regularly audited, with bug bounties available for anyone who finds a vulnerability.
When using a non-custodial crypto exchange, self-custody makes it more difficult to recover your tokens if something goes wrong. The recourse available to you will vary depending on your exchange and wallet.
With MPC exchanges, you’ll be able to recover your funds so long as you have the requisite number of shares, even if a part is lost. Smart contract wallets, meanwhile, may allow for social recovery.
Outside of this, you can create an encrypted cloud backup of your wallet. However, make sure you’re using a trusted provider with robust encryption in case your cloud provider is breached.
Fees factor into every trade, whether they be on the exchange’s side or imposed by the blockchain itself. A platform with lower fees will, in a vacuum, let you keep more of your trading profits.
However, this doesn’t paint the full picture. If a platform has lower fees but higher slippage, it’ll oftentimes be more expensive to use than a platform with higher fees that offers customizable slippage. Before committing to an exchange, make sure you understand the real cost of using it, not just the headline fees.
Ideally, you want your self-custodial exchange platform of choice to support all of the trading pairs you actively trade. More trading pairs also make it easier to enter new, promising tokens. With more trading pairs, you can respond to market shifts and pivot your portfolio more easily.
However, the number of trading pairs doesn’t tell the whole story. If some of these trading pairs have low liquidity, the resulting slippage can make those pairs not worth trading. Always research order book depth on your favorite pairs before committing to an exchange.
| Pros | Cons |
|---|---|
| More secure, no risk to your funds even if the exchange gets hacked or breached. | Few to no options for recovering funds if private keys are lost. |
| The exchange can’t freeze your assets or restrict what you get to do with them. | Slightly steeper learning curve for newcomers. |
| Little to no KYC on most platforms. | Fewer advanced trading features available. |
| Fewer jurisdiction-based restrictions on trading and DeFi activities. | Little to no recourse through customer support for user errors, such as sending funds to the wrong address. |
A non-custodial crypto exchange is a trading platform that lets you trade without depositing your funds into a platform-owned wallet.
On custodial exchanges, you deposit funds into an exchange account, through which trading happens. On non-custodial exchanges, you connect your wallet, and the entire trade executes via a smart contract or protocol without the platform ever holding your funds.
All decentralized exchanges (DEXs) are non-custodial by definition, but not all non-custodial trading platforms are DEXs. Decentralized exchanges run on smart contracts with a permissionless architecture, usually using liquidity pools to facilitate trading.
Non-custodial exchanges are a broader category. They cover DEX aggregators, instant swap platforms, and more. These platforms can use centralized servers or centralized matching engines, and may require email or other forms of verification.
Most non-custodial exchanges do not require KYC by default. However, some non-custodial exchanges still require KYC for certain functionalities(such as cross-chain swaps). Most fiat on/off-ramp providers also require KYC, so unless you’re doing crypto-to-crypto swaps, you’ll likely encounter some KYC along the way.
Depending on your jurisdiction and platform, you may also be blocked based on your IP or wallet address, preventing you from accessing the platform.
If you’re looking to avoid KYC altogether, we recommend taking a look at our list of the best no-KYC crypto exchanges instead.
It depends on your wallet. With most wallets, losing your seed phrase entirely means completely losing access to your funds. Because of this, seed phrase safety should be your top priority when using a decentralized exchange. Ensure you keep your recovery phrase in a safe, offline location, with at least 1 backup.
However, some of the best crypto wallets have developed ways to regain access to your funds even if you do lose your seed phrase. MPC technologies and cloud backups can be incredibly helpful here, providing an additional layer of protection against losing your funds.
As a general rule, yes. On centralized exchanges, you have to trust your exchange’s storage, cybersecurity protocols, and internal policies to keep your tokens safe. Self-custody means you are always in control of your tokens, mitigating any risks associated with the exchange itself.
Because of this, many of the safest crypto exchanges are self-custodial exchanges. However, non-custodial crypto exchanges have their own downsides. You’re entirely responsible for keeping your seed phrase safe and are more exposed to smart contract risks.
In practice, non-custodial exchanges are more secure if you’re technically savvy, follow security best practices, and keep your private key safe at all times. Otherwise, the lower personal burden on custodial exchanges may make them the more secure choice for you.
Yes, but it’s not always so simple. The exchange itself will only rarely facilitate this, with most fiat on-ramps handled by 3rd-party providers like Wert or Ramp Network. Off-ramps are usually more limited and may be completely unavailable in some regions. Because of this, we recommend using a reliable crypto exchange or a dedicated on/off-ramp provider to turn your crypto back into fiat.
