# SOPH

> SOPH utility, chain transition, and official contract addresses

SOPH is an ERC-20 token native to Ethereum. It launched with an original supply of
**10 billion SOPH** and was used as the Sophon Chain's gas token and for staking.

<Warning>
  The Sophon Chain is being wound down. Gas and staking—the two chain-era SOPH
  utilities—will be phased out with the chain. If you hold SOPH on Sophon, follow
  the [migration guide](/migration) to withdraw it.
</Warning>

SOPH itself does **not** need to be migrated or swapped. SOPH on the Sophon Chain is
a bridged representation of the Ethereum-native token.

## Product-funded buybacks and burns

SOPH's new model links token burns to revenue from products built by Sophon. A
portion of profits will be used to buy SOPH on the open market on an ongoing basis,
and the purchased tokens will be permanently burned. They will not be redistributed
to token holders.

The first announced burn covers more than **46.5 million SOPH** from the unutilized
staking-reward pool and node buybacks. Subsequent purchases are intended to be
funded by product revenue.

Pyre's announced revenue sources are:

* interchange fees from card transactions;
* performance fees from vault usage;
* reserve yield from PYRUSD, Pyre's custom stablecoin and settlement currency.

As tokens are burned, circulating supply contracts. Percentages in the historical
allocation schedule are calculated against the original 10 billion issuance.

## Chain-era utility transition

### Staking

Staking remains available while the Sophon Chain is operational and will be
discontinued when the chain is decommissioned. Staked SOPH positions are transitioned
to Ethereum automatically. SOPH that is unstaked is claimable on Ethereum through
[claim.sophon.com](https://claim.sophon.com).

### Guardian rewards

The Guardian programme continues on its original schedule: Guardian NFT holders
receive a pro-rata share of **20% of the original SOPH supply over three years**.
Current reward streams continue vesting on Sophon through **September 29, 2026 at
00:00 GMT**. New rewards then accrue on Ethereum. Guardian NFT holders do not need
to migrate their NFTs manually.

* Ticker: **SOPH**
* Token standard: **ERC-20**
