Summary

  • Polygon RPC https://1rpc.io/matic has been discontinued by Lava (This endpoint has been discontinued.), breaking all Polygon readonly calls for the ~⅓ of devices whose AB-test seed pins it as primary (urls[getABTestSeed() % urls.length] in ProviderURL.ts).
  • Drop the dead endpoint from RPC_URL_OVERRIDES in packages/web3-shared/evm/src/constants/viem-chains.ts, leaving the two verified-live CORS-enabled fallbacks (publicnode, drpc). A 2-endpoint list has precedent (Robinhood).
  • Surveyed replacements: thirdweb 429s without CORS headers, llamarpc/blastapi/blockpi/meowrpc/nodies dead, onfinality/ankr/lavanet/polygon-rpc.com key-gated — none suitable.
