        "note": "Lido's net staking APR (after Lido's protocol fee), derived directly from the on-chain wstETH→stETH exchange rate, which only grows as staking rewards accrue. For each window (1d, 7d, 30d) the rate at that point in the past is read from historical chain state and the growth is annualised using the real elapsed time between blocks — so these are the actual yields a wstETH holder earned, not a marketing figure. A window may be null if historical state for it is unavailable. The 7d and 30d figures are the more stable reads (1d is noisier). Live, cached ~90s.",
