Proof availability depends on the node retaining that state. The balance field is the native EVM account balance, not the default MIP20 balance returned by Metal eth_getBalance. To prove a MIP20 balance, query the token contract and its balance storage slot. Verify proofs against a trusted finalized header. See https://eips.ethereum.org/EIPS/eip-1186 for the standard response fields. ## OpenAPI ````yaml /reference/json-rpc/json-rpc.json post /eth_getProof openapi: 3.1.0 info: title: Metal JSON-RPC version: 1.0.0 description: Interactive playground for Metal's public JSON-RPC endpoints. servers: - url: https://rpc-testnet.metalntwx.com/v1/{endpointId} variables: endpointId: default: YOUR_ENDPOINT_ID description: >- Your endpoint ID from the Metal console.
