Project reality
Why the project matters
- What it does
- Citrea is a Bitcoin-anchored ZK rollup that runs a Type-2 zkEVM and settles directly on Bitcoin through Clementine, a BitVM-based trust-minimized two-way bridge for moving BTC into the rollup as cBTC. The project is built by Chainway Labs and positions CTR as the coordination asset for the Bitcoin economy.
- Who uses or pays
- Who uses and pays for the product still needs verification.
- What is live
- The current live product state is not yet recorded separately from campaign research.
- Where value flows
- The company has reported approximately $16.7M in venture funding across two rounds. A $2.7M seed round led by Galaxy Ventures (with Delphi Ventures, Eric Wall, and others) preceded a $14M Series A led by Founders Fund in October 2024, with participation from Maven11, Mirana, dao5, Erik Voorhees, Balaji Srinivasan, Nikil Viswanathan, Mert Mumtaz, and Jameson Lopp [citrea-funding, citrea-series-a]. Private audits of the rollup by Sigma Prime and public audit competitions on Cantina for both Citrea and the Clementine bridge were completed in 2025 [citrea-audit, citrea-cantina, citrea-sigma-prime-x].

Source-backed guidance
How to improve eligibility
- The CTR genesis airdrop has ended; wallets meeting the 920+ mainnet activity score or with prior testnet/devnet participation would only have qualified if they registered before May 17, 2026 at 2:00 PM UTC. Watch citrea.xyz and the official @citrea_xyz account for any future CTR distribution announcements.
Editorial judgment
Airdroplet verdict
Project-published airdrop whose registration and claim windows have ended
Best for: Readers tracking whether Citrea will run future CTR distributions, and anyone checking that the official window really is closed before ignoring a third-party 'claim' pitch.
Skip if: You are only here because a DM or third-party site is offering to reopen the CTR claim — that is not the project.
- Citrea has a visible official product and ecosystem activity, but no official airdrop allocation has been published.
- Citrea mainnet is live, the CTR token has launched, and the project ran a genesis airdrop with a published claim portal and registration window (May 11–17, 2026); the official portal now states registration and claim periods have concluded.
- Citrea has reported $16.7M in venture funding led by Founders Fund (Series A) and Galaxy Ventures (seed), with private audits by Sigma Prime and public Cantina competitions for Citrea and the Clementine bridge.
- Score lowered from A (open claim) to B (closed claim) on 2026-08-11 because the live claim window has ended, even though the project background (audits, named investors, shipped mainnet) is unchanged.
Re-ranked 2026-08-12: no material change since the 2026-08-11 closed-claim refresh — citrea.xyz/airdrop still reads 'registration and claim periods have concluded,' the post-airdrop 10M-CTR weekly stake distribution is observably running, and the project background (Founders Fund + Galaxy Ventures funding, Sigma Prime private + Cantina public audits, live mainnet) is unchanged. Project still scored 55/B — closed claim window with intact background quality.

Registration closed May 17 at 2:00 PM UTC. Funding is documented at ~$16.7M (Founders Fund Series A + Galaxy Ventures seed); audit phase completed October 2025 (Sigma Prime private + Cantina public competitions for Citrea and Clementine). Evidence drawn from Citrea blog and docs (queries 1, 3, 4, 5, 6); audit firm detail came from Citrea docs and the Cantina competition page.

- Re-researched 2026-08-11 (second pass): citrea.xyz/airdrop now reads "CTR Airdrop Has Ended — the registration and claim periods for the CTR airdrop have concluded." Updated project_overview, funding_info, airdrop_details, quick_answer, x_summary, scoring_notes, risks, tasks, campaigns, reward_explanation, cost_and_risk, eligibility_tips, score_reasons, sources, and opinions to reflect the closed status; demoted from A/82 (open claim) to B/55 (closed claim) since the live opportunity is over while the project background (Founders Fund + Galaxy Ventures funding, Sigma Prime + Cantina audits, live mainnet) is unchanged. Added new sources citrea-sigma-prime-x (Sigma Prime audit X post), citrea-stake-post (CTR staking distribution), and citrea-coinmarketcap (CTR live data). Web queries 1, 3, 4, 5, 6 + an additional "airdrop ended" confirmation query all returned; X window unavailable (xurl unauthenticated).Sources: citrea-airdrop-page, citrea-blog-ctr, citrea-sigma-prime-x, citrea-stake-post, citrea-coinmarketcap, citrea-funding, citrea-series-a, citrea-cantina
- Re-researched 2026-08-12 (third pass): citrea.xyz/airdrop still reads 'The registration and claim periods for the CTR airdrop have concluded' — closed status unchanged. Project background confirmed intact: Founders Fund-led $14M Series A (Oct 2024, CoinDesk + PR Newswire), $2.7M Galaxy Ventures-led seed (Feb 2024, CryptoSlate press release), Sigma Prime private audit + Cantina public competition for both Citrea and the Clementine bridge (2025), and a Type-2 zkEVM rollup anchored to Bitcoin via the BitVM-based Clementine two-way bridge. X-window was Path C (web_search) only; `xurl` is still unauthenticated. Path C surfaced two new X sources: 'Week 1 of the 10M CTR distribution has started' (confirms the post-airdrop weekly stake distribution is operational) and an earlier thread noting 'More airdrops may follow to grow participation in the Bitcoin economy via xCTR' (future-airdrops hint, not a new active claim). Updated x_summary, x_summary_date, scoring_notes, research_checked_at, next_review_at, opinions[], sources[] (added citrea-stake-post-week1 and citrea-future-airdrops). No change to score (55/B) or tier (B). Web queries 3, 4, 5, 6 returned solid evidence; queries 1 and 2 (announcement-surface) hit Brave Search 429 and were not re-run because the existing citrea-airdrop-page + citrea-blog-ctr sources already cover the airdrop surface.Sources: citrea-airdrop-page, citrea-blog-ctr, citrea-funding, citrea-series-a, citrea-audit, citrea-cantina, citrea-sigma-prime-x, citrea-stake-post, citrea-stake-post-week1, citrea-future-airdrops

Direct answers
Questions
Is the Citrea reward confirmed?
The CTR genesis airdrop itself was confirmed by the project's own portal and blog (snapshot May 5, 2026; registration closed May 17, 2026 at 2:00 PM UTC), but the official portal now states both the registration and claim periods have concluded. If you did not register before the cutoff, you are not eligible for this distribution. Any site other than citrea.xyz offering an 'open' claim is not the project.
How should I investigate Citrea safely?
Start at the official website linked here, review current campaign terms, and avoid links sent through DMs or unofficial groups. Do not share a seed phrase or approve transactions you do not understand. The current genesis airdrop is closed; treat any third-party 'claim' portal as not the project.
