Second, a Bitcoin development lab, has officially launched Bark — its implementation of the Ark protocol — on the Bitcoin mainnet, opening up self-custodial bitcoin payments to developers and everyday users alike without the complexity traditionally associated with Lightning Network Or on-chain transactions.
It is a bark that has been built. Ark protocol. A layer-2 solution which allows for large number of users sharing on-chain UTXOs by using trees of presigned off-chain transactions. Fee costs are spread across the participants and individual custody is preserved.
Ark is a custodial alternative that does not need channel management.
“We wanted to make it ridiculously easy for users to get started with self-custodial bitcoin, hold it, and spend it, without surprise fees, and without having to manage channels or liquidity,” Steven Roose, the CEO of Roose Group Inc. wrote a blog.
Second’s Ark is now publicly available for payment. The launch includes a full developer toolkit — the Bark SDK — written in Rust with language bindings for Kotlin, Swift, React Native, Flutter, Go, Python, and WebAssembly. Second ships Barkd for server environments. This standalone wallet daemon exposes a REST API with OpenAPI specification.
Many applications have already been enabled for mainnet at the launch.
Noah is the full stack mobile Ark wallet, combining a React Native Frontend and a Rust Backend. Arke is an open-source iOS wallet designed around bitcoin.design’s UX principles. Satsigner is a mobile wallet that brings Sparrow’s UTXO workflows and management to users. Bark Wallet, an Umbrel application, supports Ark, Lightning and on-chain payment.
A BTCPay Server plugin — also built by Second — lets merchants process self-custodial Lightning payments without opening channels or managing liquidity.
Second has raised Private investor provides $5.1 Million and the team consists of 11 members. It has attracted notable talent in the industry, such as former Blockstream engineers.
The launch comes at a moment of heightened competition in the Bitcoin layer-2 space, with multiple protocols — including Ark Labs’ Arkade and statechain-based solutions — vying to close the gap between self-custody and user experience.
Second Will also host a live AMA on Stacker News On June 9, at 10:00 am EST.
