Top up with native Solana  the fastest L1 we support. ~5-second settlement, fees measured in fractions of a cent, no KYC.
Solana settles in under 5 seconds at typical network conditions. For a card top-up flow where you want to issue and use a card within a minute of deciding, native SOL is the fastest path we support  faster than even USDT TRC-20.
Two properties make Solana ideal for card funding:
The trade-off historically has been network reliability (Solana has had multi-hour outages). For card funding where the worst case is "retry in 30 minutes," the speed gain on the happy path is worth the occasional retry on outage days.
We accept both. The difference:
If you fund $50-$500 frequently, native SOL is the way. If you fund $5000+ where a 1% price swing matters, prefer USDT SPL on Solana.
During heavy load, transactions may need 2-3 slots instead of 1, adding maybe 2-3 seconds. We credit when finality lands.
Deposit addresses remain valid; funds to a previously generated address still credit your account.
Your transaction will simply pend until the network resumes. We credit whenever the tx finalises, however long that takes. No funds are at risk in your wallet.

$5 equivalent. Below that, even Solana's tiny fees become noticeable as a percentage.
Not relevant to our flow  once you send the SOL, it converts to your account balance. No staking happens.
Pick a BIN above, top up with any of 20 cryptocurrencies, and your card is ready to use the moment the deposit confirms.
