Espresso Airdrop Claim

The current claim pays ESP to original airdrop recipients who followed a specific staking path. The first boost is 256% of the staking rewards accrued since token launch. It is a boost to the reward amount, not a 256% return on the number of ESP staked. The Foundation also adds 155 ESP to each eligible account.

Two later milestones are announced. The one-year milestone has a 359% boost on rewards accrued since the three-month mark. The two-year milestone has a 420% boost on rewards accrued since the one-year mark. The claim period stays open until one month after the final window opens. The Foundation did not state the exact final calendar date in the page reviewed.

The original airdrop used 10% of ESP's initial 3.59 billion token supply. A further 24.81% was reserved for future airdrops, grants, and incentives, but that reserve is not a current public task. Do not farm random activity because the reserve exists.

Checking the portal does not require a deposit. The current article does not say whether a claim needs Ethereum gas, so check the wallet before confirming. A network fee, also called gas, is the payment for processing a blockchain transaction. The wallet should show the network, contract, action, and fee.

The larger risk comes from staking. ESP can rise or fall in price while it is staked. Smart contracts can fail, and a validator can go offline. Under the boost rules, unstaking more than half before a milestone can forfeit that milestone. The Foundation allows up to 14 days to move to another validator if the selected validator goes offline.

Phishing is the immediate claim risk. The only verified portal in this guide is claim.espresso.foundation. The Espresso Foundation says its team will not contact you first or ask for a seed phrase.

• Use the same wallet that claimed and staked the original airdrop.
• Check the portal before paying any fee. It should show whether the wallet qualifies.
• Keep at least 50% of the original allocation staked if you intend to preserve later milestone eligibility.
• If your validator goes offline, follow the official 14-day redelegation exception rather than an unsolicited support message.
• Do not buy ESP or start a new stake expecting it to qualify for past airdrop boosts.

Claim if you are an eligible original airdrop staker; everyone else should skip

Best for: Original ESP airdrop recipients who met the three-month staking rules

Skip if: You did not receive and promptly stake the original ESP airdrop

• The current claim and exact reward formula are official.
• The claim portal uses a Foundation domain and is linked from the official announcement.
• No new deposit is needed to check or claim an existing allocation.
• Eligibility is narrow and based on activity that is already over.
• Future boost dates are milestone-based and the exact calendar deadlines are not fully published.
• Re-checked 2026-08-11: claim.espresso.foundation still responds 200; the Foundation's 2026-07-28 article still describes the 256% boost + 155 ESP bonus as the open window; no new milestone window or material change in the public record.
• Re-ranked 2026-08-12: confirmed Series A ($29.9M, Mar 2022, Greylock + Electric Capital led, with Sequoia, Blockchain Capital, Slow Ventures, Polychain, Coinbase Ventures) and Series B ($28M, Mar 2024, a16z crypto led); confirmed external audit history via Informal Systems, Cantina, and Runtime Verification (ESP token review 2025-11-13); no material change to score or tier.

Team & Transparency 24/25 + Fundamentals & Traction 24/30 + Tokenomics & Airdrop Design 23/25 - Risks 4/20 = 67/100. Espresso has a highly reputable funded team, production network, published audits and bug bounty, a 10% initial airdrop, four-year contributor and investor vesting with a one-year cliff, broad eligibility, and comprehensive anti-sybil methodology. The active boosted-reward claim is narrow: only original recipients who staked on time qualify, and staking, Ethereum fees, validator performance, and token-price exposure remain. Re-ranked 2026-08-12: refreshed the project_overview to reflect the shared-sequencer framing and the funding_info to cite Series A ($29.9M, 2022, Greylock + Electric Capital led) and Series B ($28M, 2024, a16z crypto led); no material change in score.

Espresso is a shared sequencing and data-availability network that other Layer-2 and rollup chains plug into to get fast finality, preconfirmations on transaction ordering, and cross-chain state visibility. Its consensus layer is called HotShot (a BFT protocol) and its DA layer is Tiramisu; together they let rollups publish blocks to a shared confirmation point rather than running their own isolated sequencer. Espresso Mainnet 0 went live in November 2024. Espresso Systems builds the network; the Espresso Foundation manages the ESP token and the airdrop.

ESP is an Ethereum-based proof-of-stake token used to secure Espresso's validator set. The original ESP airdrop was not a generic "swap or bridge to qualify" campaign: eligibility came from past activity across the Espresso community and selected partner ecosystems, gated by a proof-of-humanity registration that closed on February 9, 2026.
