Overview

Kast is a Solana-native card that turns on-chain USDC into everyday spending power. Rather than routing through a centralized exchange balance, Kast settles purchases directly against stablecoins held in the Solana ecosystem, taking advantage of Solana's sub-second finality and near-zero transaction costs. Issued on the Visa network, the card is accepted at tens of millions of merchants worldwide and works through Apple Pay and Google Pay.

Kast's pitch is speed and global reach: instant settlement, no staking lock-ups, and availability in 150+ countries including many regions underserved by older crypto cards. Rewards are paid in SOL on eligible spending, giving holders exposure to Solana's native asset rather than a card-specific utility token.

How It Works

You fund the card by holding USDC (and supported stablecoins) in your Kast account on Solana. At point of sale the card converts the required amount of USDC to fiat instantly, using Solana settlement under the hood. Because there is no pre-staking requirement, you can start spending as soon as your balance is funded.

SOL rewards accrue on eligible purchases and are credited to your Kast wallet. There is no tier lock-up — your reward rate is consistent regardless of how long you have held funds. Virtual cards can be issued instantly for online spending, with physical cards available in supported regions.
