Square Crypto Is Creating a 'Lightning Development Kit' for Bitcoin Wallets
Square Crypto is hoping to galvanize Lightning development with a new tool kit, currently under construction.

Square Crypto, the payment company's bitcoin-focused wing, is building a "Lightning Development Kit" for wallet and app developers to more easily build on the layer-2 solution.
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."

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Here are the winners and losers (so far) in bitcoin mining from Nvidia's $2B CoreWeave investment

Nvidia’s deepened partnership with CoreWeave raises pressure on bitcoin miners pivoting to AI infrastructure.
What to know:
- Shares of most bitcoin miners who have shifted business plans to AI infrastructure fell after Nvidia announced a fresh $2 billion investment in CoreWeave.
- One analyst says Nvidia’s deepening partnership with CoreWeave could divert GPU access and funding away from independent miners trying to pivot into AI and high-performance computing.
- Core Scientific, which CoreWeave attempted, but failed, to acquire in 2025, is the only miner posting gains on Monday.
