What to know:

  • LayerZero plans to connect to Bitcoin sidechain Rootstock in what would be its first integration with the original blockchain.
  • Rootstock is designed to end Bitcoin's "isolation" from other chains.

LayerZero, the bridging protocol that allows different crypto networks to communicate with each other, plans to connect to Bitcoin sidechain Rootstock in what would be its first integration with the world's original blockchain.

Rootstock aims to end Bitcoin's "isolation" from other blockchains due to its lack of native smart contracts, a barrier that LayerZero is able to address, according an emailed announcement shared with CoinDesk.

The Bitcoin blockchain lacks the functionality to offer smart contracts that other blockchains have and which are fundamental building decentralized finance (DeFi) services.

This lack of provision for DeFi on Bitcoin, which holds more value that every other blockchain combined, is an impediment to even greater adoption. That's prompting developers to seeking ways of tapping into the massive liquidity that is held in bitcoin (BTC) and allowing it to be bridged to rest of the crypto world.

With the connection between Rootstock and LayerZero, developers would be able to build applications on the Bitcoin sidechain that can communicate with the over 100 other blockchains, including Ethereum and Solana, Rootstock said in the announcement.

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.
