Frequently Asked Questions
MoltyDEX is the only x402 payment handler with automatic token swapping for AI agents on Solana. It enables AI agents to automatically pay for APIs using any token, with zero platform fees and best prices via Jupiter aggregator. MoltyDEX handles the entire x402 payment flow automatically, from detection to token swapping to payment confirmation.
An x402 payment handler is a service that automatically processes HTTP 402 Payment Required responses. MoltyDEX is the only x402 payment handler that includes automatic token swapping, allowing AI agents to pay for APIs even when they don't have the exact token required. It handles token conversion, payment processing, and request retries seamlessly.
When an AI agent makes an API call and receives a 402 Payment Required response, MoltyDEX automatically intercepts it, parses the payment requirements, checks the agent's token balance, swaps tokens if needed using Jupiter aggregator, makes the payment on Solana blockchain, and retries the original API request. All of this happens automatically without any manual intervention.
MoltyDEX supports all SPL tokens on Solana, including SOL, USDC, USDT, and any custom token. It automatically swaps between any tokens as needed for x402 payments, routing through Jupiter aggregator to find the best prices across all Solana DEXes.
MoltyDEX charges 0% platform fees - completely free x402 payment handling and token swaps. No platform fees, no hidden costs. You only pay Solana network fees (paid in SOL separately).
Yes! MoltyDEX is highly secure. All transaction signing happens client-side - your private keys never leave your wallet or system. MoltyDEX only builds unsigned transactions that you sign locally before sending to Solana. This ensures maximum security for your funds and eliminates the risk of key exposure.
MoltyDEX is the only DEX aggregator built specifically for x402 payments and AI agents. While other aggregators focus on trading, MoltyDEX focuses on automated payment flows. It includes the only x402 auto-pay agent with automatic token swapping, handles edge cases specific to agents, and is optimized for pay-per-use API scenarios.
Yes! While MoltyDEX is optimized for x402 payments, you can use it for any token swap on Solana. The web interface provides a simple way to swap tokens manually, and the API works for any programmatic use case. You get the same benefits: 0% fees, best prices via Jupiter, and secure client-side signing.
Getting started is easy! For humans: simply connect your wallet on the homepage and start swapping tokens. For AI agents: install the MoltyDEX SDK (@moltydex/agent), configure the HTTPInterceptor with your Solana wallet, and enable autoSwap. Check out our developer documentation at /developers for detailed integration guides.
MoltyDEX includes robust error handling. If a swap fails, the system provides clear error messages and the agent can handle it gracefully. The x402 auto-pay agent includes retry logic and proper error reporting. Common issues like insufficient balance or network congestion are handled automatically with appropriate user feedback.
