Quickstart
Fetch the latest Monad block number. Replace YOUR_API_KEY with a key from the dashboard. New accounts start on the Free plan, no card required (see getting started):
curl https://rpc.solidrpc.io/YOUR_API_KEY/evm/143 \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'Standard methods only
Monad is served by full nodes only, there is no archive state, and trace_* and debug_* methods are not available on this chain. The standard EVM method set works as usual. See the networks page for per-chain coverage.
Limits and errors
Quotas and rate limits are account-wide, not per-chain. Method calls to Monad draw from the same response-unit quota and rate limit as every other network. Error bodies are identical everywhere. See the error reference.
