Non-Custodial Crypto Swaps Explained: Who Holds Your Coins?

What is a non-custodial crypto swap?

A swap is non-custodial when you keep the private keys to your coins, so no company can move them without your permission. There are three common ways to swap. In an exchange account, the exchange holds the keys. With a wallet-connected service such as 1inch, you keep your keys and authorise swaps or token spending from your wallet. With a deposit-address service, you need no account: you send coins to a one-time deposit address for that swap, and the swap runs under the provider's terms. Each asks you to trust something different.

SwapBee publishes this guide and works the third way. ChangeNOW and 1inch, both quoted below, are two of SwapBee's 22 providers (as of 26 October 2026). Sources were checked on 9 October 2026 unless an archive date is given.

What do "custodial" and "non-custodial" mean?

Custody is about who holds the private keys. Ledger Academy puts it this way: custodial wallets are "issued by a third party that holds your private keys for you, whereas non-custodial wallets allow you to hold your own keys" (Ledger Academy). A wallet does not store coins. It holds the keys that sign changes to them on the blockchain.

With a custodial account, Ledger says, you "hold a claim against the provider" for your assets, much like a bank balance, and the platform can freeze or restrict your account. With a non-custodial wallet, only you can authorise a transaction, and you alone look after the recovery phrase.

1inch describes the same split. It says most centralized exchanges have been custodial, which leaves users exposed to risks such as "exchange hacks" and "freezing of withdrawals". It says its own platform and wallets are non-custodial, which "prevents 1inch Network from accessing or moving funds without permission" (1inch Help Center).

What are the three ways to swap, and who holds the keys?

Exchange account

On an exchange such as Coinbase, you sign in to your account and pick Convert to trade one coin for another (Coinbase Help, as archived 7 October 2025). Coinbase calls its balances a "Hosted Cryptocurrency balance service" (Coinbase fees, as archived 2 October 2026). Ledger notes that with a custodial account, your access "depends entirely on the provider remaining secure, operational, and solvent".

Wallet-connected DEX aggregator

Here the service finds a route and you authorise it from your wallet; check the scope of each approval. 1inch says all activity on its protocols requires users "to sign each transaction within their own wallet", and the first trade of most tokens needs an approval transaction.

• Jupiter is a Solana example. Jupiter Spot searches "Meteora, Raydium, Humidifi, and >100 other liquidity sources", and you connect Jupiter Wallet, another Solana wallet, or a Ledger or Trezor. Its Quick Accounts let you log in with email or a social account; Jupiter says they are non-custodial and "Your private key can be exported at any time". It also calls them "Signless": trades go through "without approving every transaction" (Jupiter docs).
• Zerion calls its wallet a self-custody wallet, "available as a mobile app and browser extension", where "only you hold your private keys", and you can swap and bridge from it (Zerion Help Center). Its security page says you can "Set your own spending limit on every approval" and "Review and revoke what you've already approved" (Zerion).

What you trust here is the code you sign for, and your own reading of each request. 1inch's security page adds that "all interactions with smart contracts and decentralized protocols carry inherent risks" (1inch).

Deposit-address service

ChangeNOW calls this kind of service an "exchanger": "you conduct trading operations with it", and "All you need is to enter the amount of coins you want to exchange and the wallet address" (ChangeNOW Help Center, article from 2020, as archived 7 October 2025).

Its current FAQ says standard swaps need no registration or account. Its fee list includes a "network fee for transferring coins to our liquidity provider". It says flagged transactions are put on hold until the customer confirms their identity, and that it will try to "temporarily freeze" funds reported as stolen when there is "substantial evidence". ChangeNOW describes itself as offering "both non-custodial and custodial options" (ChangeNOW FAQ).

So you hand over no keys and open no account, but you rely on the provider's terms; read them before you send.

What should I check before I swap?

Our trust checklist covers how to vet a platform. For custody, ask five things:

1. Who holds the keys, and where do the coins go?
2. What am I signing? An approval can let a contract move a token; set a limit if your wallet allows it.
3. Where can a refund go? The refund address is where the provider can return your coins if the swap fails. Refunds follow the provider's policies and decisions. On SwapBee, the refund address must be on the same network as the coin you send.
4. Whose terms apply? On SwapBee, the order screen names the provider and links its rules and privacy policy.
5. Can a check pause the swap? Providers may run their own checks. Our AML page explains how checks are split between SwapBee and providers.

Where does SwapBee fit?

As of 26 October 2026, SwapBee compares quotes from 22 providers and lists 9,152 coin/network entries across 51 blockchains. There is no account and no wallet connection: you send your coins to a deposit address. You set a receiving address; most providers also ask for a refund address. After you confirm, you get a Swap ID to track the swap. SwapBee doesn't charge a separate fee, but it does earn from your swap. On swaps through exchange services, the provider shares part of its fee with SwapBee. On on-chain DEX swaps, SwapBee adds a small markup to the quote. Both are already in the quote you see; nothing is added on top (see our terms). Your wallet also charges its usual network fee to send the deposit.

There are no accounts, balances or pooled wallets: most swaps send your deposit straight to the provider, and on-chain DEX swaps use a one-time swap address SwapBee operates, which executes the swap and sends the output to your wallet automatically. Before you confirm, each quote's provider policy shows who holds your deposit. As of 26 October 2026, that is a one-time address SwapBee operates for LI.FI, 0x, KyberSwap, Bungee and 1inch, and the provider's deposit address for the other 17. Our launch post explains why we built SwapBee. SwapBee is part of the BlockBee ecosystem.

FAQ

Is swapping on a DEX aggregator always non-custodial?

1inch says its design "prevents 1inch Network from accessing or moving funds without permission". But an approval is that permission, so check what you approve and revoke old approvals you no longer need.

What happens to my coins with a deposit-address service?

You send them to a one-time deposit address for that swap, and the swap runs under the provider's terms. If the swap fails, the provider can return your coins to your refund address; refunds follow the provider's policies and decisions.

Where does my deposit go on SwapBee?

There are no accounts, balances or pooled wallets: most swaps send your deposit straight to the provider, and on-chain DEX swaps use a one-time swap address SwapBee operates, which executes the swap and sends the output to your wallet automatically. Before you confirm, each quote's provider policy shows who holds your deposit.

Can an exchange freeze my coins?

Ledger says a custodial platform "can freeze or otherwise restrict your account". In a non-custodial wallet, no third party holds the keys to do that.
