US crypto firm Nomad has been hit by a US$190-million (R3.2-billion) theft, blockchain researchers said on Tuesday, the latest such heist to hit the digital asset sector this year.

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 said $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 US exchange Coinbase Global, makes software that connects different blockchains — the digital ledgers that underpin most cryptocurrencies.

The heist targeted Nomad’s “bridge” — a tool which allows users to transfer tokens between blockchains.

Blockchain bridges have increasingly become the target of thefts, which have long plagued the crypto sector. Over $1-billion has been stolen from bridges so far in 2022, according to London-based blockchain analytics firm Elliptic.

Heists

In June, US crypto firm Harmony said that thieves stole around $100-million worth of tokens from its Horizon bridge product.

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 US linked North Korean hackers to the theft.

Nomad described itself as “security-first” business which Zwould 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. — Elizabeth Howcroft, (c) 2022 Reuters
