Coinbase said Wednesday that a US regulator intends to sue it in court if it launches a planned program letting users earn interest on lending cryptocurrency.

The New York-listed cryptocurrency platform — the largest US exchange for bitcoin and other private digital currencies — said that the Securities and Exchange Commission handed it a Wells notice in relation to its Coinbase Lend program, signaling its intention to sue the company in court. As a result, Coinbase said it won't launch Lend until at least October.
