Download header registry ABI ↓

The viewer batches all four tokens with Multicall3. It reads counts and live state first, then the recorded ranges, pinned to the same block.

Use runCount(token) and runs(token, i) for the history. Use candidates(token, second) for a timestamp, and readCurrent(token) for the live token state. Runs can share a second; show every possible value. A current token read does not extend the recorded history.

For an 8-decimal token-priced oracle observation, share price is answer × 1e18 ÷ multiplier, still in 8-decimal USD units. Multiple candidate multipliers give a range of share prices.

For activity, index MultiplierProven and LiveStateObserved from the multiplier registry. The ranges remain the history source; events alone do not reconstruct them.
