Nomad said in a tweet that it was "aware of the incident" and was currently investigating, without giving further details or the value of the theft.
Crypto analytics firm PeckShield told Reuters $190 million worth of users' cryptocurrencies were stolen, including ether and the stablecoin USDC. Other blockchain researchers put the figure at over $150 million.
San Francisco-based Nomad did not immediately respond to a request for comment.
The company has notified law enforcement and is working with blockchain forensics firms to try to identify the accounts involved and get back the funds, it said in a statement to crypto news outlet CoinDesk.
Nomad, which last week raised $22 million from investors including major U.S. exchange Coinbase Global, makes software that connects different blockchains - the digital ledgers that underpin most cryptocurrencies.
In March, hackers stole around $615 million worth of cryptocurrency from Ronin Bridge, used to transfer crypto in and out of the game Axie Infinity. The United States linked North Korean hackers to the theft.
Nomad described itself as "security-first" business which would keep users' funds safe.
PeckShield said that a small proportion of the coins were moved to a so-called "mixer", which masks the trail of crypto transactions, while around $95 million was held in three other wallets.
Canadian online brokerage Wealthsimple wants to chart a future enabling the real-world use of cryptocurrencies rather than simply facilitating trading, but is likely to face unexpected costs and uncertain regulatory terrain along the way.
