Encryption technology firm Evervault has launched a new subscription service that securely stores cryptocurrency wallet seed phrases to prevent theft and loss.
- Seed phrases are a series of words that give users access to the cryptocurrency in their digital wallet. The phrases usually contain 12, 18 or 24 words, leading Evervault to name its service 121824.
- The 121824 service is secured by the same encryption technology that Dublin-based Evervault offers to financial and health information companies.
- User data remains encrypted at all times, though it can still be processed and shared. Evervault never stores the data and developers don’t configure crypto algorithms or manage keys.
- Access to 121824 costs $1 per wallet per month, or $10 per wallet per year. Users access the service through the website, which currently has the waitlist open with a full launch expected in the coming weeks.
- Seed phrase security became a plot point in the headline-grabbing arrest of a couple that allegedly laundered billions of dollars in bitcoin from the 2016 Bitfinex hack.
- When the arrest was announced on Feb. 8, U.S. authorities said they were able to access wallets controlled by Ilya Lichtenstein and Heather Morgan after decrypting a spreadsheet of seed phrases saved to a cloud storage service.

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.
