Frequently asked questions
Do you store seed phrases?+
No. BIP39 and password tools run fully client-side. We never send seeds or passwords to a server.
What addresses can I validate?+
EVM (with EIP-55), Bitcoin, Solana, and Tron format checks, plus QR generation.
Is validation a guarantee?+
Format and checksum checks help catch typos, but still confirm the address in your wallet before sending funds.
