# Staking Badges (Historical)

> Summary of the historical 2025 SOPH airdrop staking-badge programme

<Warning>
  This programme is historical. Its eligibility window closed on **July 27, 2025**,
  and SOPH staking is now being phased out with the Sophon Chain.
</Warning>

Eligible airdrop recipients could qualify for a Sophon profile badge by staking
their airdrop during the 2025 claim window and maintaining that stake for at least
three months after the window closed.

## Historical badge tiers

| Tier       | Historical requirement                                                  |

| **Gold**   | Staked more than 75% of the airdrop and at least 250,000 SOPH in total. |
| **Silver** | Staked more than 75% of the airdrop.                                    |
| **Bronze** | Staked more than 50% of the airdrop.                                    |

These requirements are preserved for reference and are not an active offer. For the
