Bitcoin is a trusted cryptocurrency. However, its ability to run complex Smart Contracts and create DApps is minimal. Bitcoin experiences inherent scalability issues.

Developers & Enthusiasts are creating Bitcoin Layer 2 that helps develop innovative Smart Contracts and Decentralized applications.

If you are a techy looking for a Bitcoin Layer 2 solution, you have landed on the right page.

I have listed Top 10 Bitcoin Layer 2 that you should know about 2024 in this listicle.

Each of the discussed Layer 2 solutions has a unique value proposition and history. The items are listed according to the longevity of the projects.

Let’s get the ball rolling.


Stacks is a Bitcoin Layer 2 enables smart contracts & apps with Bitcoin as a secure base layer. Stacks founders include Muneeb Ali, Peter Czaban, & Ryna Shea. Initially founded as BlockStack, later renamed as Stacks.

Muneeb Ali holds a Ph.D. in computer science from Princeton University. Stacks was founded in the Princeton Computer Science Department to solve the underlying problems of current web and mobile apps.

Stacks was founded in the year 2013.

BlockSurvey is built on the Stacks Ecosystem.

This EVM-compatible Bitcoin Layer 2 and Smart Contracts Platform is designed for a more decentralized world. Deploy smart contracts on Rootstock and leverage the security of the Bitcoin network. Rootstock is secured by the same computing power that secures Bitcoin.

Rootstock was founded in 2015 by RSK Labs to overcome Ethereum’s limitations. It leverages Bitcoin’s unmatched security & stability.

Additionally, RSK offers faster transaction speeds that are approximately 10 times faster than Ethereum, with gas fees that are 50 times cheaper.

Rootstack uses Smart BTC (RBTC) as its native coin. This coin facilitates minting, swaps, gas fees, and more.

Make sure you use a wallet that supports RBTC. MyEtherWallet, Metamask, Trezor, & Exodus are a few wallets that support RBTC.

Zulu is the first Bitcoin Layer 2 platform to introduce a dual-layer architecture. ZuluPrime acts as Layer2 on Bitcoin with EVM compatibility. ZuluNexus acts as Layer3, focusing on native Bitcoin format innovations.

Like other Layer2 solutions, Zulu helps build Smart Contracts & DApps on the BitCoin network.

Zulu is compatible with EVM (Ethereum Virtual Machine) & UTXO (Unspent Transaction Output). This fusion of technologies opens endless possibilities. Zulu is a High-Performance Zero Knowledge Stack.

Francis and Luke are the co-founders of the Zulu Network. After a remarkable 20-year journey in finance, Francis led transformations in corporate and startups before finding the Zulu Network along with Luke.

Tuna Chain

The first modular Bitcoin Layer 2 that features a ZK-OP (zero-knowledge / Optimistic) hybrid approach. Experience the seamless fusion of Bitcoin's security with Ethereum's versatility. TUN is the native coin.

While Bitcoin is the most trusted cryptocurrency, its capability for complex smart contracts and advanced applications remains limited. Tuna Chain ambitiously endeavors to bridge this gap, integrating EVM compatibility into Bitcoin’s L2 framework and thus expanding the realm of possibilities for Bitcoin’s application and utility.

It has a modular DA Layer. DA layer ensures that all kinds of data, such as transaction details, smart contracts data, and other off-chain data, are available to all the nodes on L1, L2, and L3 networks.

With this groundbreaking dual-phase architecture, you can accelerate Secure Transactions and Empower Smart Contracts. In addition to security, you can also experience slashed transaction costs.

Tuna Chain is backed by investors like ArkStream Capital, Normie Capital, Serafund, and a few more.
