NAUT tracks 19 Bitcoin layer 2 projects whose own description says they are a Bitcoin L2, rollup or sidechain, read on 13 November 2026. Of the 19, 12 have launched a token and 12 have at least 1 funding round on NAUT's record, while 4 show neither.
How this list was built: on 13 November 2026 NAUT read 29 project rows that looked like Bitcoin scaling projects and kept a row only when its own description says it is a Bitcoin L2, rollup or sidechain. 10 rows came out, each for its own reason: 1 Ethereum L2, 1 data-availability layer that runs its own L1, 1 bridge, 1 wallet and DEX, 1 lending app built on an L2, 1 launchpad, 1 Ordinals marketplace, 1 memecoin, 1 RWA asset platform and 1 learn-to-earn education token. 12 of the 19 projects then had at least 1 claim put to outside sources (19 claims in all): 11 came back confirmed, 6 contradicted and 2 not found. The 7 projects never read outside NAUT are Bitcoin Hyper, GEB, nexio, Bison, Taproot Chain, Dovi and AILayer.
Which Bitcoin layer 2 projects are on NAUT, and which have a token or funding?
All 19 are below, grouped by the type each project's own description gives. "Rounds" means at least 1 round sits on the project's NAUT page. The Raised column prints a total only where an outside source confirmed it; "Partial" means NAUT holds only part of the rounds, "Disputed" means outside sources gave a different figure, and "Unchecked" means no outside source was found.
| Project | Type | Token | Rounds | Raised |
|---|---|---|---|---|
| zk-rollup | CTR | Yes | $16.7M | |
| zk-rollup L2 | MERL | Yes | Partial, left out | |

By type, the Bitcoin rollups lead with 4 zk-rollups and 2 other rollups, then 5 EVM-compatible L2s, 2 projects that call themselves a Bitcoin sidechain and 6 L2s on other designs. 9 projects have both a token and rounds on NAUT, 3 have rounds and no token (Botanix, Ark Labs, Bitcoin Hyper), 3 have a token and no round (Dovi, Fractal Bitcoin, AILayer) and 4 have neither (GEB, nexio, Bison, Taproot Chain).
Which Bitcoin L2 tokens did outside sources confirm?
8 of the 12 tokens were confirmed on an outside page this run. Bitlayer's docs say "BTR is the governance token of the Bitlayer ecosystem, primarily used for ecosystem incentives and governance." Citrea's docs call CTR "the coordination asset for the Bitcoin economy", and The Block reported the CTR launch in May 2026. CoinMarketCap says "$FB can be used as the transaction fee for the network itself" for Fractal Bitcoin. Merlin Chain MERL, BOB BOB, Zulu Network ZULU and SatoshiVM SAVM were each found listed as live tokens. Mintlayer's own blog announced the ML pre-TGE sale for 13 March 2023. The tokens of Plasma, Mezo, AILayer and Dovi rest on NAUT's record alone.
Which Bitcoin layer 2 projects list the most backers on NAUT?
These are distinct backers across each project's rounds on NAUT, so they count NAUT's record, which can miss names a press release gives. Plasma carries 1 backer on its record and sits outside the chart.
Which investors back more than 1 Bitcoin L2?
8 backers appear on 2 or 3 of these projects in NAUT's record. None carries a lead flag on NAUT, so treat each as a participant.
