Know Your Issuer proves that a token was issued by your organization. You find the token on-chain, attest its details, and sign with the wallets that control it.
1

Paste the token address

On Overview, paste the token’s contract address into Verify a new asset. Passport finds the token on-chain and reads its controlling wallets.

Sign with each controlling wallet

Each wallet with authority over the token, such as the owner or mint authority, signs a short off-chain message. No funds move. One signature covers every token that wallet controls. For a multisig, sign as the multisig or as any one of its signers. See wallet verification for the methods per chain.
