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.

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.

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.
