Stable RPC endpoint

Stable (chain ID 988) is served over HTTPS POST JSON-RPC 2.0. Full and archive nodes back the endpoint, supporting standard EVM methods, historical state, debug_* methods. Every plan includes Stable, including Free.

Quickstart

Fetch the latest Stable 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):

Request example

curl https://rpc.solidrpc.io/YOUR_API_KEY/evm/988 \
  -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 Stable; historical queries route to archive nodes automatically by block age, at no surcharge.

The debug_* tracing namespace is available:

Request example

curl https://rpc.solidrpc.io/YOUR_API_KEY/evm/988 \
  -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 not available on this chain; use debug_traceTransaction and debug_traceBlockByNumber instead.

Limits and errors

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