  "totalUsers": number; // (Optional) Total number of individual wallets holding the LST.
  "totalBalanceUsd": number; // (Optional) The total balance held in USD.
  "supportedAssets": [ 
    {
      "label": string; // Name of the Earn Tier, limit to 25 characters.
      "slug": string; //  Use the Staking Rewards Asset Slug (Learn more below).
      "apr": number; // Annual Reward Rate before Fees and in %
      "fee": number; // Fees in % deducted from the APR
      "aprBreakdown": [ // % breakdown of rewards origin, check example
        {
         "slug": string; // Slug of the payout asset
         "apr": number //  Portion of total APR by this asset
        }
       ]
       "duration": number; // Time in Seconds the user locks the funds
       "minDepositAmount": number; // Minimum amount the user has to deposit, token unit - not $ !
       "maxDepositAmount": number // Maximum amount the user can deposit, token unit - not $ !
    }
  ]
}

The more detailed your breakdown is, the more data we can display on your provider profiles and the respective asset profiles.
