1inch review
This swap aggregator, operated by Degensoft Ltd. in the British Virgin Islands, functions across various blockchains. Swaps do not require an account. You sign them within your own wallet, keeping your coins there. There is no routine ID check, but 1inch may ask for due-diligence data in limited cases, and 1inch says it does not interact with wallets tied to sanctioned persons. Currently, access to the 1inch interface is free, and in Fusion mode, the resolvers cover the gas fees. In our view, this aggregator suits EVM users who accept wallet screening.
ID only if flagged
1inch asks for ID only if a payment is flagged, per its own pages. You hold the keys.

1inch in the US and elsewhere
In the US
US availability: Available
If you are a US person, US sanctions rules apply to you whether or not a service asks for ID.
Outside the US
Where 1inch does not serve
2 places in its terms- Prohibited Localities: any state, country or region subject or target of comprehensive trade or economic sanctions, embargoes or similar restrictive measures, or included in the Sanction Lists (UN, US/OFAC, EU, UK, British Virgin Islands)
- Regional Availability: certain products or features unavailable in certain countries or regions, including the United Arab Emirates
Regional rule: Not stated1inch's own pages we checked do not say. This is not the same as no.
Where you live and the provider's terms
Many services on this page do not serve every country. Some exclude people because of where they live or their citizenship, not only where they connect from. Read the provider's terms before you send funds. If the terms exclude you, do not use the service, and do not try to get around the restriction, for example with a VPN.
Taxes
A service that does not ask for ID does not change your taxes. In the US, the federal income tax return asks a yes-or-no question about digital assets, and you must report digital asset transactions whether or not they result in a gain or loss. In the UK, you may owe Capital Gains Tax when you sell, swap or spend crypto, and you must keep your own records. Rules in other countries differ.
No KYC is not anonymity
"No KYC" here means the provider says it does not ask for ID in the cases its terms describe. It does not make you anonymous. 1inch's terms say it can ask for ID in these cases: Due Diligence Checks or verification requirements when separately requested by 1inch; Additional eligibility, verification, accreditation or whitelisting requirements set by third parties, issuers or protocols for certain products or assets; Incentive Programs: compliance screening including sanctions and risk screening. Regulated exchanges you send funds from or to may have to collect information about who sends and who receives a crypto transfer. Your tax duties stay the same.
Funds can be held
If a provider asks for more information during a swap or a withdrawal, it may hold your funds until it gets it. Its terms decide what happens next. In the UK, a crypto business that asks for information on a transfer to or from a self-custody wallet, and does not receive it, must not pass the funds on. Read what the provider's terms say before you send. 1inch's terms say that if a check is requested and not completed: no funds held: assets stay in the user's self-custodial wallet; restriction only affects access to 1inch products.

Every value carries the date we last checked it. The values on this page were checked between October 14, 2026 and October 23, 2026.
