01What is a Vision - Vpioneer Test Chain RPC?
An RPC endpoint connects wallets and applications to Vision - Vpioneer Test Chain. Use the endpoints above for JSON-RPC requests, and keep alternatives available for regional endpoint failures or rate limits.
02Add Vision - Vpioneer Test Chain to MetaMask
Use “Add to wallet” to request the network configuration. Always verify chain ID 666666, currency VS, and the selected RPC before approving.
03Public RPC safety
Public endpoints are third-party infrastructure. They may log requests, enforce limits, or become unavailable. Never place private keys, seed phrases, or secrets in an RPC request.
04Common RPC errors
Rate limits, browser CORS rules, network mismatch, and temporary provider failures are common. Try another listed endpoint and verify the returned chain ID.
