Check the details before moving your crypto.
Review asset and network compatibility, confirm destination details, track a test transfer, and keep a record of the checks performed — without giving CryptoPreflight custody of your funds.
Who controls the destination address, and whether the platform still supports this network. Confirm both directly with the receiving platform.

One overlooked detail can make a crypto transfer difficult — or impossible — to recover.
CryptoPreflight gives you a structured pause before you press send: it compares the transfer instructions you were given against the details you are about to use, has the recipient enter their own details independently, follows a small test transfer, and leaves you a private record of exactly what was checked.
The exchange's deposit page asked for Ethereum, and Polygon is selected on the sending side. The two addresses look identical.
An XRP deposit to an exchange with no destination tag recorded. Our rules flag the asset and destination type and ask you to check.

How a preflight works
- 1Transfer details
Asset, amount, where it is going, the network and the destination address. Nothing else is asked for.
- 2Compatibility checks
Each check shows what was checked, the result, the source, when it was recorded, what could not be verified and your next step.
- 3Destination confirmation
For your own account, guidance to take the address from the deposit screen itself. For someone else, an expiring single-use confirmation link.
- 4Test transfer
Paste the hash of a small test you sent yourself. We separate seen on-chain, enough confirmations, recipient says it arrived, and exchange credit.
- 5Preflight Receipt
A private record of the checks completed and not completed, with sources, timestamps and your acknowledgements.
Four things a preflight does for one specific planned transfer.
The network, asset and address the destination asked for, set against the ones you are about to use.
The recipient types their own deposit details without seeing yours, and the server compares the two.
A small first transaction read from public chain sources, keeping on-chain confirmation separate from an account actually being credited.
A private Preflight Receipt listing the details reviewed, each result, its source and timestamp, and anything left unresolved.

Crypto transfers usually cannot be reversed. A wrong network, a missing tag or one altered character is often the end of it.

Where CryptoPreflight stops
Never enter a seed phrase, private key, recovery phrase, or a wallet or exchange password or recovery code. CryptoPreflight will never ask for any of them. Signing in to your own CryptoPreflight account is separate, and only needed to save a record.
CryptoPreflight never asks you to sign in to a wallet or an exchange, and never asks for wallet or exchange passwords, credentials or recovery information.
Separately: saving a preflight requires your own CryptoPreflight account — an email address and a password you choose here, or Google sign-in — so your records stay yours. That password is for this site only. The demonstrations need no account at all.
CryptoPreflight reports the results of limited checks using the information available at the time shown. It does not verify every risk, guarantee receipt, or authorize your transfer. Independently confirm the destination and transaction details in your wallet or exchange. Crypto transfers may be irreversible.
