PANews reported on December 15th that Ripple announced the first expansion of its stablecoin RLUSD to Layer 2 networks, according to its official blog. Ripple will collaborate with the cross-chain interoperability protocol Wormhole and the NTT token standard to launch testing on Optimism, Base, Ink, and Unichain. Ripple expects to launch RLUSD on more chains next year after receiving final regulatory approval. Subsequent launches of RLUSD on other chains are subject to testing and approval by the New York Department of Financial Services. It is understood that RLUSD was initially only issued on XRPL and Ethereum.
