> Skill based on Starknet specs (starkware-libs/starknet-specs), generated from `sources/starknet`. Doc path: `sources/starknet/` (README.md, starknet_vs_ethereum_node_apis.md, api/release.md, api/*.json, wallet-api/wallet_rpc.json).

Starknet specifications define the node JSON-RPC API (read, write, trace, WebSocket) and the Wallet RPC for dApp–wallet interaction. The node API mirrors Ethereum naming with a `starknet_` prefix and uses field elements, block tags, and structured errors. Use this skill when implementing or calling Starknet RPC clients, indexers, or wallet integrations.
