+
+Learn about the Photon, Ethermint's staking token. {synopsis}
+
+## Introduction
+
+::: tip
+The photon's initial distribution and supply is still TBD and will be announced in the future.
+:::
+
+The photon is the staking token used in Ethermint.
+
+## Base Denomination
+
+Ethermint uses [Atto](https://en.wikipedia.org/wiki/Atto-) Photon as the base denomination to maintain parity with Ethereum.
+
+```
+1 photon = 1×10⁻¹⁸ aphoton
+```
+
+This matches Ethereum denomination of:
+
+```
+1 ETH = 1x10⁻¹⁸ wei
+```
