Back up seed phrases offline
Write your seed phrase on paper or keep it in offline media. Do not screenshot it, upload it, or send it through chat, email or web forms.
Security
Astryn Wallet is based on self-custody. No wallet can reverse confirmed on-chain transactions or recover lost seed phrases, private keys or file vault passphrases.
Write your seed phrase on paper or keep it in offline media. Do not screenshot it, upload it, or send it through chat, email or web forms.
Astryn Wallet will not ask for your seed phrase, private key, file vault passphrase or verification code. Stop immediately when a page asks for them.
Before sending assets, confirm the chain, target address, asset, amount and fee. Confirmed transactions usually cannot be reversed.
A watch wallet stores only public addresses. It can monitor cold wallets or public addresses, but cannot sign or send transactions.
Use a long, hard-to-guess passphrase and keep it offline. If it is lost, encrypted file contents cannot be recovered.
Use the official Astryn Wallet website for Android, Windows and Linux packages, and verify the SHA256 value.
Use trusted devices, keep systems updated and avoid importing wallets on compromised or public devices.
