Scroll Airdrop Eligibility: Snapshot Dates & Sybil Criteria Explained

Scroll Airdrop Eligibility: Snapshot Dates & Sybil Criteria Explained

The Wait is Over: Scroll Token Allocation

The cryptocurrency community has turned its full attention to Scroll, a leading zkEVM Layer 2 solution, following the official announcement of its native token, $SCR. For months, participants have engaged with the ecosystem through the "Sessions" program, accruing Marks in hopes of a retroactive distribution. As the network transitions toward decentralization, understanding the specifics of the snapshot and eligibility criteria is vital for all participants.

Critical Snapshot Dates

Timing is everything in decentralized finance (DeFi). The Scroll team has confirmed the specific timeline for the first phase of the airdrop allocation. Understanding this cut-off is essential for determining why your current Marks balance may differ from your final allocation.

  • Snapshot Date: The critical snapshot for eligibility was taken on October 19, 2024.
  • Significance: This block height captures the state of all wallets. Any liquidity provided, bridges attempted, or transactions executed after this specific date are not counted toward the "Phase 1" allocation.

Eligibility: The 'Marks' System

Unlike early DeFi airdrops that rewarded simple transaction counts, Scroll utilized a dynamic, points-based metric known as Marks. Eligibility is primarily determined by a time-weighted formula involving:

  1. Liquidity Provision: Users who bridged ETH or stablecoins (USDC, USDT) to the Scroll network via the official bridge or third-party bridges.
  2. DeFi Participation: Assets deposited into lending protocols (such as Aave on Scroll) or decentralized exchanges (DEXs like Ambient and Nuri).
  3. Session Consistency: The longer the capital was deployed, and the earlier the user entered the ecosystem (Session Zero vs. Session One), the higher the Marks accumulated.

Sybil Resistance and Disqualification Criteria

To ensure fair distribution to genuine users, the Scroll foundation has implemented rigorous Sybil detection mechanisms. This is a filtering process designed to remove "industrial farmers"—bot networks or users manipulating multiple wallets to exploit the system.

If you find your wallet ineligible despite having activity, it may have triggered one of the following Sybil criteria:

  • Cluster Behavior: Algorithms identified wallets that were funded by the same source wallet or moved funds in identical, automated patterns across a cluster of addresses.
  • Volume Thresholds: Wallets with negligible transaction volume or balances essentially at zero (dust) at the time of the snapshot were likely filtered out to prioritize high-quality users.
  • Contract Interaction: Accounts that interacted with a statistically improbable number of unique contracts in a short time frame solely to "farm" transaction counts without genuine economic activity.

What Comes Next?

For those who participated in Scroll Sessions, the focus now shifts to the official claim portal. Security Warning: Users are advised to only interact with links verified via official Scroll social media channels (such as their X/Twitter handle or official Discord) to avoid sophisticated phishing scams targeting airdrop recipients.

If you missed the October 19 snapshot, the ecosystem is still in its early stages. The introduction of the $SCR token marks the beginning of governance, and future incentives for continued liquidity provision remain a distinct possibility for subsequent phases.
