Offchain Labs, the company behind Ethereum scaling solution Arbitrum, announced this week the testnet launch of Nitro – a test environment for a pending major update to the optimistic rollup’s technical stack.
- According to Offchain, the update to Arbitrum will cheapen fees, speed up transactions, and make it easier for native Ethereum apps to interface with the Layer 2 chain.
- Offchain founder Steven Goldfeder told CoinDesk that Arbitrum’s fees, which were usually around 50 cents to $1 before the update, will be cut by at least 50%.
- Rollups like Arbitrum scale the Ethereum network by processing transactions and executing smart contracts – the mini-computer programs that run on blockchains – on separate rollup-specific chains.
- The data generated on Arbitrum gets bundled up and passed back down to Ethereum, where Ethereum network actors can check whether the data is valid.
- Last week, a $625 million theft from Ethereum’s Ronin sidechain showed the potential vulnerability of sidechains, which, unlike rollups, do not inherit their security from a layer 1 blockchain.
- In March, Offchain also announced Arbitrum AnyTrust chains – a cheaper, faster, more centralized alternative to its optimistic rollup.
- Arbitrum is currently Ethereum’s largest rollup solution, with nearly $2.5 billion total value locked (TVL), according to DefiiLlama.
Edit: August 30, 2022 15:24 UTC: Clarifies that the update is in testnet.

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.
