Is Keystone safe?
Keystone's terms place the keys with you and disclaim access to them. No party is disclosed as able to block an address. No primary-source incident is recorded, which is not proof of none. Its terms name no gambling rule. Liability is capped at the price paid for the product.
Keystone: keys held on a device you hold; who can block an address: none disclosed in the documents read; gambling clause: not disclosed; 0 primary-source incidents recorded. From its own terms, documents last checked . Not a rating. Drawn by the CryptoGuardz Register Desk from the record.

Keystone review: the documents
This is a review of the documents Keystone publishes, not a test of the product: no transaction was signed and no code audit was read. The contracting party named is Yanssie HK Limited; on jurisdiction the record says: Hong Kong SAR. The custody position comes from the Keystone Terms of Use, last updated 4 March 2026, read 2026-10-07. The record quotes 6 clauses across 4 topics, and 2 sub-service clauses where the app hands a swap, purchase or staking to another party. Keystone's terms place the keys with you and disclaim access to them. No cloud or hosted backup is offered; recovery depends on the copy you keep. Liability is capped at the price paid for the product. Its terms name no gambling rule. 6 points could not be verified and are listed below.
Has Keystone been hacked?
No primary-source incident was found for Keystone in this collection: no company disclosure, no public vulnerability register entry and no regulator action. That is not proof that none happened. It is the absence of a search result, and a forum post or a press report is not recorded here until a primary source confirms it.
Keystone support and scams
The official domain in the record is keyst.one. Type the domain yourself rather than following a link to it.
Real support never asks for a seed phrase. The recovery phrase restores the whole wallet on any device, so whoever is given it can move everything it controls, and no support agent needs it to answer a question. What Keystone stores, by the record: Nothing by Keystone, by the terms. The user holds the recovery phrase.
Support links reached from ads or direct messages are the commonest drain. A search ad, a reply to a public complaint or a direct message offers help, the link opens a page that looks like keyst.one, and the page asks you to “validate” or “sync” the wallet by entering the phrase. Once it is typed in, the wallet is emptied and nothing in the terms gives a way back.
If money has already gone, the next message offering to get it back is the commonest second loss. The FBI, the FTC, the CFTC and the UK FCA warnings about it are quoted on crypto scam recovery: what is real.
Keystone fees and limits
One clause in the record set a fee or a limit on what you can do through the app. They are quoted as written. Network fees paid to the chain are not part of the record.
Swap sub-service · 1 of 1Retrieved 2026-10-07
When you use the Swap feature within the App, a service fee may apply. This fee is either included in the quoted price or otherwise disclosed to you.
The gaps in this record, as the record states them. A point listed here was looked for and not confirmed; it is neither a finding for Keystone nor against it.
The swap provider or aggregator behind the Keystone Nexus Swap feature. Not named in the terms or privacy policy.
Whether the Keystone Nexus app has a suspension or termination clause. The Terms of Use contain none that was found, and no separate app terms were located.
Whether the swap service screens addresses. Neither document says.
Place of incorporation of Yanssie HK Limited. Inferred from name and address only; not checked against the Hong Kong Companies Registry.
TON and BNB Chain. Listed as supported assets but not in a quoted network sentence, so not recorded in chains.
Documented incidents. No primary-source incident was located. Absence here is absence of a search result, not evidence of no incident.
