state_getStorage – Mythos JSON-RPC Method

state_getStorage retrieves runtime storage values at a given block state. On Mythos, use it to monitor NFT collection configs, marketplace order books, and token issuance without waiting for events.

Parameters

Parameter	Type	Required	Description
key	string	Yes	Hex-encoded storage key (Twox/Blake hashed)
blockHash	string	No	Block hash to query historical state

Example: Treasury Account Snapshot

The Mythos treasury pallet maps to the 20-byte account 0xef96002999670d623b6aa36f771d89ad527aff8b. Query its System.Account entry to verify balances before scheduling disbursements.

  "result": "0x000000000000000001000000000000000000c16ff28623000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000080"
}

Decode the SCALE payload as AccountInfo<AccountData> to obtain free = 0.01 MYTH, reserved = 0, and flags = 0x80.

Decoding in JavaScript

import { ApiPromise, WsProvider } from '@polkadot/api';

async function treasuryBalance() {
  const api = await ApiPromise.create({
    provider: new WsProvider('wss://api-mythos-archive.n.dwellir.com/YOUR_API_KEY')
  });

  const accountId = '0xef96002999670d623b6aa36f771d89ad527aff8b';
  const info = await api.query.system.account(accountId);
  console.log('Free balance (plancks):', info.data.free.toString());
}

treasuryBalance().catch(console.error);

Tips

• Snapshot state_getStorage alongside marketplace events to reconcile escrow balances.
• Use blockHash when auditing DAO proposals or NFT drops that may have been reverted.
• Combine with state_queryStorageAt for successive key updates during live events.
