What could be the reason for my AVAX endpoint not functioning?

Introduction

The Avalanche Chain is much more than an EVM-compatible ecosystem, as it comprises multiple built-in chains. Therefore, to access a particular chain, you must specify the desired chain.

Suggested solution

If you would like to call EVM methods, you will need to add the C-Chain URI at the end of your endpoint URL, as follows: https://nd-123-456-789.p2pify.com/AUTH_KEY/ext/bc/C/rpc

Here's a cURL example

curl -X POST \
'https://nd-123-456-789.p2pify.com/AUTH_KEY/ext/bc/C/rpc' \
--header 'Content-Type: application/json' \
--data-raw '{
"jsonrpc": "2.0",
"method": "eth_blockNumber",
"params": [],
"id": 1
}'

If you'd like to connect to the endpoint via WebSocket you'll need to use the following URL: wss://ws-nd-123-456-789.p2pify.com/AUTH_KEY/ext/bc/C/ws

Here's a wscat example with the eth_syncing request:

wscat -c wss://ws-nd-123-456-789.p2pify.com/AUTH_KEY/ext/bc/C/ws
Connected (press CTRL+C to quit)
> {"id": 1, "jsonrpc": "2.0", "method": "eth_syncing"}
< {"jsonrpc":"2.0","id":1,"result":false}

Conclusion

Understanding the C-Chain’s endpoint structure ensures smooth interactions with Avalanche’s EVM. By specifying the correct endpoint and utilizing the appropriate methods, developers can harness the power of smart contracts on the Avalanche network. Happy coding! 🚀
