The goal of MOB, which is based on Stellar blockchain technology, is to be able to work efficiently on mobile devices while also protecting users' privacy. The launch on Signal has long been rumored, dating back to when Facebook announced plans to launch its libra stablecoin in early 2019.

MOB stands out from a pack of messenger-native crypto coins because it has actually launched. Telegram’s TON was nuked by U.S. regulators; Facebook’s libra (now diem) remains in a state of near-completion.

At this time, the MOB payment feature will only be available to users in the U.K., and only on iOS and Android. Desktop support is not included.

"I'm terrified for Signal," Matthew Green, a cryptographer at Johns Hopkins University who sits on the Zcash Foundation board, told Wired, adding:

"Signal as an encrypted messaging product is really valuable. Speaking solely as a person who is really into encrypted messaging, it terrifies me that they're going to take this really clean story of an encrypted messenger and mix it up with the nightmare of laws and regulations and vulnerability that is cryptocurrency."

On the other hand, integrating privacy-oriented cryptocurrencies into relatively popular communications apps may give users an attractive onramp and interface to enter into the world of crypto.

In a blog post announcing the launch of the feature in beta, the company said users can link a MOB wallet to Signal, send funds, receive funds, keep track of their balances and review transaction histories.

“As always, our goal is to keep your data in your hands rather than ours; mobile coin’s design means Signal does not have access to your balance, full transaction history, or funds,” Signal wrote. “You can also transfer your funds at any time if you want to switch to another app or service.”

Mobilecoin is currently only trading on FTX.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

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.
