Square Crypto Hires Matt Corallo to Boost Bitcoin Development
Square Crypto just hired one of the world’s most prolific bitcoin developers.

Square Crypto, the division of the publicly traded payments company that focuses exclusively on bitcoin, just hired one of the world’s most prolific bitcoin developers.
Chaincode Labs alum and Blockstream co-founder Matt Corallo previously authored notable efficiency improvements such as the rust-lightning implementation, which makes it easier for users to build and interact with layers of the bitcoin network. Corallo tweeted Tuesday that he’ll be joining the team to experiment with models for accelerating bitcoin development.
Corallo told CoinDesk he hopes to work with “a team that crosses the entire range of talent and type of experience” in order to address issues related to the bitcoin user experience for various use cases.
“It’s a little bit different than Chaincode or Blockstream research,” he said. “To work together on projects with a tightly knit team that are a little bit more focused. Hopefully take on bigger problems, and problems that cross more talent bases.”
This team, headed by former Google director Steve Lee, is still hiring for several positions. According to a tweet by Square founder Jack Dorsey, the team will need at least two more engineers and a designer to work full-time on open source contributions to bitcoin. Job listings reveal the San Francisco fintech company is seeking an additional operations lead as well.
In reference to the range of companies that now sponsor open-source development in the cryptocurrency space, from BitMex to the Zcash Foundation, Corallo added:
“I think things have improved greatly in terms of the breadth of different funders. … We’ve had an explosion in people that want to fund open source work in the space.”

Pudgy Penguins: A New Blueprint for Tokenized Culture

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.
