Hackers returned about half of the $610 million or so they pilfered Tuesday in what was likely one of the biggest cryptocurrency thefts on record in the burgeoning DeFi sector.

In a unusual twist, the online thieves pledged to return the entire amount stole from a decentralized finance, or DeFi, protocol known as PolyNetwork that lets users swap tokens across multiple blockchains. It isn’t clear from the PolyNetwork website who runs the protocol.
