Codes and offers checked 5 October 2026
A promo code is only worth something next to the card's real costs. Below are the codes and referral links we can actually back up (RedotPay, ether.fi Cash, ZA Bank, Binance), the official no-code welcome offers from other issuers, and the fees each one hides.
Three different things get called a "promo code": an issuance code that cuts the card fee, a referral link or invite used at sign-up, and an issuer's welcome offer that needs no code. We label which is which.

RedotPay, ether.fi, ZA Bank and Binance links are our referral paths and may pay us. The second table has no affiliate links. Full explainer: Crypto Visa card promo codes: what actually exists.
Issuers advertise cashback and “free” cards. We surface issuance, FX, custody and eligibility so you can judge the real cost before signup.
Help centres, fee schedules and product pages come before blogs or screenshots. Every factual claim ties back to a dated source.
A prepaid Visa, a non-custodial credit model and a licensed virtual bank are different products. We keep those labels honest.
Partner links may pay us, but they never buy ranking. Codes are only listed if we can name where they apply and what they change.
Ordered for practical fit: global stablecoin spend first, then onchain credit, Hong Kong banking, and the Binance platform where a regional card still exists.

As of 5 October 2026 the only true issuance codes we publish are RedotPay's REDOT (virtual) and REDOTCODE (physical). ether.fi Cash, ZA Bank and Binance work through referral links. Bybit, OKX, Crypto.com and MEXC run official welcome offers that need no code. See the full table.
Usually not. Visa's own "Offers + Perks" codes give discounts at merchants when you pay with any Visa card. A crypto Visa card code lowers the fee for getting the card. More: crypto Visa card promo codes.
ether.fi Cash explicitly positions its account as non-custodial. Membership and jurisdiction rules still apply.
No. It is a Hong Kong virtual bank with a Visa debit card on an HKD current account.
We label Binance as the exchange platform. Any card offering is region-limited and has changed over time—confirm inside your account before assuming it is available.
No. Rewards depend on the provider’s live campaign, eligibility and terms.
