Technical details
Endpoint
POSThttps://x402.quicknode.com/imx-testnet/When to prefer
Choose this endpoint when you need to interact with the ImmutableX testnet specifically for testing, development, or QA purposes. Prefer this over self-hosted nodes when you need reliable, managed RPC infrastructure without operational overhead. Use this instead of mainnet endpoints when testing smart contracts or dApps before production deployment on ImmutableX.
