Announced Tuesday, the new kit includes an API, language tools, demo apps and other features to help developers integrate support for Lightning payments into their own wallets. Existing bitcoin wallets will also be able to support Lightning through the new kit, rather than requiring companies to build a separate wallet.

The tools will help developers create better user experiences, a Medium post explained.

"For bitcoin to become a widely used global currency – one that can’t be stopped, tampered with or rigged in anyone’s favor – improvements to bitcoin’s UX, security, privacy, and scaling are required," the group said.

The post indicated the kit is still being built out and did not provide a timeline for release, but said "today's Lightning infrastructure is incomplete without features like these."

Pudgy Penguins: A New Blueprint for Tokenized Culture

Pudgy Title Image

Pudgy Penguins is building a multi-vertical consumer IP platform — combining phygital products, games, NFTs and PENGU to monetize culture at scale.

What to know:

Pudgy Penguins is emerging as one of the strongest NFT-native brands of this cycle, shifting from speculative “digital luxury goods” into a multi-vertical consumer IP platform. Its strategy is to acquire users through mainstream channels first; toys, retail partnerships and viral media, then onboard them into Web3 through games, NFTs and the PENGU token.

The ecosystem now spans phygital products (> $13M retail sales and >1M units sold), games and experiences (Pudgy Party surpassed 500k downloads in two weeks), and a widely distributed token (airdropped to 6M+ wallets). While the market is currently pricing Pudgy at a premium relative to traditional IP peers, sustained success depends on execution across retail expansion, gaming adoption and deeper token utility.
