Tempo on Aug. 12 launched Tempo Earn, a product that lets fintechs pay their users rewards on idle stablecoin balances and keep part of the return, with payroll platform Deel as the first named deployment.

Section 4(a)(11) of the GENIUS Act bars any permitted payment stablecoin issuer from paying holders "any form of interest or yield" for holding the token. Tempo Earn sources the yield somewhere else: tokenized money market funds, onchain lending and institutional credit, with the platform choosing the assets and deciding "how rewards are split between your platform and your customers," according to the announcement. The issuer never pays the holder. A lending protocol does.

Deel built the reference implementation in June, when it launched DLUSD with what is effectively Stripe's full stack: Bridge issuing the token through Open Issuance, Privy providing embedded wallets, Tempo settling. Morpho vaults deployed on Tempo generate the rewards.

Deel's help center, last updated June 2, puts a number on it: "At launch, the promotional target rate is up to 4% APY," described as "a promotional incentive rate" that is "variable, not guaranteed, and driven by market conditions." Neither Deel nor Tempo has disclosed who funds that rate or what share Deel keeps. Deel covers transaction and network fees, which Tempo's case study puts at $0.001 per transfer paid in stablecoins.
