Functions Documentation¶

function load_chainlist_from_json_text¶

json::JsonResult< std::vector< RpcEndpointConfig > > load_chainlist_from_json_text(
    std::string_view json_text
)

Parse chainid.network chains.json into normalized RPC endpoint configs.

Parameters:

json_text Raw chains.json array text.

Return: Vector of RpcEndpointConfig, or JSON parse error.

Filters deprecated chains, wss:// URLs, and API-key placeholder URLs. Deduplicates by chainId + URL.

function filter_to_configured_chains¶

std::vector< RpcEndpointConfig > filter_to_configured_chains(
    std::vector< RpcEndpointConfig > endpoints,
    const std::vector< uint64_t > & configured_chain_ids
)

Filter endpoint configs to only those matching configured chain IDs.

Parameters:

endpoints Endpoints to filter (consumed by move).
configured_chain_ids Set of chain IDs that are configured/provisioned.

Return: Filtered endpoints (only configured chains remain).
