Supported Chains & Assets

- Unified Experience: Send stablecoins across different chains using a single interface
- Automatic Routing: Transactions are automatically routed to the most efficient chain
- Cost Optimization: Smart routing reduces gas fees and transaction costs
- Hyperlocalized Assets: Access region-specific stablecoins and assets

Frequently Asked Questions
Can I send assets across different chains?
Yes! NEAR Intents automatically handles cross-chain routing, so you can send USDC from NEAR to a recipient who prefers to receive on Ethereum (when available).
Do I need different wallets for different chains?
No. reply.cash provides a unified wallet experience across all supported networks.
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.
