Polygon PoS

Polygon PoS, a Bor execution client checkpointing to Ethereum through Heimdall. Chain ID 137 (0x89), fees in POL, blocks about every ~2 s. Served by Bor 2.10.0. Every example below was captured from a live response on this network.

Endpoint​

https://rpc.public.crouton.digital/mainnet/polygon

Public, no API key, JSON-RPC 2.0 over HTTPS. Batch requests are supported, and the endpoint sends CORS headers for any origin, so browser clients can call it directly.

curl --request POST \
  --url https://rpc.public.crouton.digital/mainnet/polygon \
  --header 'content-type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}'

The Try it console on this page calls exactly this endpoint from your browser, so every snippet it generates is the request that just ran.

Node notes
  • Bor adds its own namespace: bor_getAuthor, bor_getCurrentValidators, bor_getRootHash and bor_getSignersAtHash.
  • State sync transactions appear at the end of a block and are not signed by a user account.
  • debug_getBadBlocks, debug_getRawHeader and debug_getRawReceipts are not implemented on this node.
