Quickstart
Fetch the latest Arc Mainnet block number. Replace YOUR_API_KEY with a key from the dashboard, new accounts start on the Free plan, so upgrade or activate PAYG before calling this network (see getting started):
curl https://rpc.solidrpc.io/YOUR_API_KEY/evm/5042 \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'Archive access and tracing
There is no separate archive endpoint for Arc Mainnet. Historical queries route to archive nodes automatically by block age, at no surcharge.
The debug_* tracing namespace is available:
curl https://rpc.solidrpc.io/YOUR_API_KEY/evm/5042 \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"debug_traceTransaction","params":["0xTRANSACTION_HASH",{"tracer":"callTracer"}],"id":1}'Parity-style trace_* methods are also available.

Limits and errors
Quotas and rate limits are account-wide, not per-chain. Method calls to Arc Mainnet draw from the same response-unit quota and rate limit as every other network. Error bodies are identical everywhere. See the error reference.
