After two years of development, Ark Labs has officially launched the public beta of Arkade, a new native Layer 2 network built directly on Bitcoin. Backed by investors including Draper Associates, Axiom, and Fulgur Ventures, the project represents one of the most significant advancements to Bitcoin’s scalability and programmability since the Lightning Network’s debut nearly a decade ago.

Virtualizing Bitcoin Transactions Without Changing Its Core
Arkade is based on the Ark Protocol, first proposed in 2023. It introduces Virtual Transaction Outputs (VTXOs) — offchain representations of Bitcoin’s native Unspent Transaction Outputs (UTXOs). This design enables faster, cheaper transactions while maintaining Bitcoin’s existing security and consensus model.

Unlike many newer “Layer 2” projects that rely on sidechains, bridges, or wrapped tokens, Arkade remains fully native to Bitcoin. It doesn’t require any changes to Bitcoin’s base layer or introduce additional trust assumptions. Instead, it works through Ark Service Providers (ASPs) — operators that coordinate offchain transactions and periodically batch them into a single onchain transaction.
Importantly, ASPs never take custody of user funds. Each VTXO is backed by a presigned Bitcoin transaction, allowing users to withdraw assets to the main chain at any time, even if an ASP goes offline or acts maliciously.
Expanding Bitcoin Beyond Payments
While Arkade initially emerged as an alternative to the Lightning Network, its role has evolved into something broader. Beyond payments, Arkade enables lending, trading, and asset issuance — financial operations that were previously impractical on Bitcoin without wrapped tokens or custodial systems.
“We realized we weren’t just building another payment rail,” said Alex Bergeron, Ark Labs’ Ecosystem Lead. “Arkade supports lending protocols, trading platforms, and smart wallets directly on Bitcoin. These are applications that were previously impossible without compromising custody.”
Ark Labs CEO Marco Argentieri added that the launch marks “the beginning of Bitcoin’s evolution as programmable money.” The company argues that while Bitcoin’s $2 trillion market cap proves its staying power as “digital gold,” its limited base-layer functionality has prevented it from competing with programmable ecosystems like Ethereum.
“Arkade unlocks Bitcoin’s full potential without compromising what makes it valuable,” Argentieri said. “By virtualizing Bitcoin’s transaction layer, we’re enabling developers to build directly on Bitcoin, not around it.”
Arkade also complements the Lightning Network rather than replacing it. Integrations with services like Boltz, Breez, BlueWallet, BTCPayServer, and exchanges such as BullBitcoin allow users to move liquidity between Lightning and Arkade seamlessly.
Bringing Stablecoins Back to Bitcoin
Alongside the Layer 2 launch, Ark Labs introduced Arkade Assets, a framework for issuing and managing multiple asset types — including stablecoins — on Bitcoin.
Stablecoins, now a core part of the digital economy with over $200 billion in circulation, have largely migrated to other blockchains due to Bitcoin’s limited programmability. Arkade Assets aims to change that, providing a native foundation for stablecoin infrastructure similar to Lightning Labs’ Taproot Assets protocol.
“Tether pioneered stablecoins on Bitcoin over a decade ago, but the ecosystem lacked the infrastructure to support the sophisticated applications users demand,” Argentieri explained. “Arkade finally provides that foundation — bringing stablecoins back to the world’s most secure blockchain.”
The Road Ahead
The public beta marks the beginning of a broader rollout. Ark Labs plans to expand Arkade with enhanced scripting tools, additional security features, and support for advanced financial applications in the coming months.
“We’re not just launching a product,” Bergeron said. “We’re establishing the infrastructure for the next decade of Bitcoin development.”
