Circle’s Arc blockchain to debut with institutional access via Fireblocks

Circle’s new layer 1 blockchain will debut with Fireblocks support as the stablecoin sector expands, with Circle and Tether vying for market dominance.

Circle’s new layer-1 blockchain Arc will integrate with Fireblocks, a New York–based digital asset custody and tokenization platform serving more than 2,400 banks, asset managers and fintechs.
