In an email to clients and a letter posted on the company website on Wednesday, Unchained Capital CEO Joe Kelly said ActiveCampaign (AC), an outside email marketing provider used by Unchained until earlier this year, was hit with a social engineering attack last week. Unchained Capital is a bitcoin-only financial services provider.
Kelly pointed out the attack occurred on the AC platform, meaning that only information shared with AC – client email addresses, usernames, account status, whether the client had an active multisig vault or loan with Unchained Capital and possibly IP addresses – may have been exported without authorization.
Not compromised, said Kelly, were any of Unchained's systems, meaning client profile information that was never shared with AC was not leaked. This would include data including physical addresses, Social Security numbers, dates of birth, IDs, phone numbers, bank account numbers, passwords, bitcoin BTC$89,145.47 addresses, bitcoin balances, loan balances, trading activity, vault statements and loan statements.
Kelly added that while client bitcoin custody is protected by multisig cold storage, clients nevertheless should be aware of what happened and be vigilant against phishing attacks.
"We are deeply sorry this incident occurred as we take our clients’ privacy very seriously," concluded Kelly. "We want to reinforce the fact that, due to our collaborative custody model, no such incidents could ever put any client funds at risk."
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.
As DeFi investors seek stable, uncorrelated returns, R3 is building Solana-native structures to bring private credit and trade finance into crypto markets.
What to know:
R3 has repositioned itself around tokenization and onchain capital markets, with Solana as its strategic base.
The firm is targeting high-yield, institutional assets like private credit and trade finance, packaged in DeFi-native structures.
Liquidity, not tokenization itself, is the next unlock for real-world assets onchain, according to R3 co-founder Todd MacDonald.
