#PROM is thrilled to introduce another infrastructure partner into our ecosystem. Meet @arpaofficial, a permissionless threshold BLS signature network.

ARPA builds a verifiable on-chain randomness oracle, Randcast, which is now live on Ethereum, Optimism, Base, and Redstone, with plans to expand to more chains. This innovation aims to enable more builders in the realm of Web3 gaming.

Strong infrastructure products always empower the Web3 ecosystem, and we’re looking forward to boosting cross-product exchange within our ecosystem with the impact of the ARPA team.

Stay tuned for further announcements!
