Best Multi-Chain Crypto Cards

Multi-chain crypto cards let you spend assets from multiple blockchains without manual bridging or swapping. Sweepbase has identified 13 crypto cards with explicit multi-chain or cross-chain support — connecting Ethereum, Solana, Polygon, Avalanche, Base, Arbitrum, and other networks to a single Visa or Mastercard. This matters because DeFi users increasingly hold assets across multiple chains; a multi-chain card eliminates the friction of consolidating funds before spending. Key factors include the number of supported chains, whether the card auto-bridges at the point of sale, gas fee handling, and which tokens are directly spendable vs. requiring conversion.
