Frequently Asked Questions​

Can I top up from other blockchains?​

Yes! You can top up your Solana wallet from other chains. See Cross-Chain Topup for instructions.

Do I need different wallets for different chains?​

No. You only need a Solana wallet to use reply.cash. If you want to top up from other chains, you can use wallets on those chains, but funds will be converted to Solana USDC.

How are exchange rates determined?​

We use real-time market data from multiple sources to ensure competitive and fair exchange rates.

What happens if a transaction fails?​

All transactions are atomic - if any part fails, the entire transaction is rolled back and your funds are returned.
