Tempo on Aug. 12 introduced Tempo Earn, a product designed for fintech platforms to offer rewards on idle stablecoin balances while keeping part of the return, with payroll platform Deel named as the first deployment. Deel has now integrated the earn feature directly into its stablecoin wallet, allowing contractors to opt in with one tap and receive automatically accruing rewards on idle DLUSD balances without lockups or minimum holdings while retaining full liquidity. The setup routes rewards through Morpho vaults on Tempo. Tempo said its Morpho integration went live on May 18, 2026, and the earn feature deployment began in June 2026. Argentina was the first market to receive access, part of a rollout focused on contractors outside traditional banking strongholds such as the U.S., UK and Eurozone. Tempo has positioned itself as Deel's exclusive blockchain partner for wallet infrastructure and yield services, alongside Stripe's Bridge for stablecoin rails and Privy's embedded wallet technology. Tempo's mainnet launched in March 2026 and was built with native account abstraction, enabling functions such as batched transactions, gas payments in tokens other than the native chain token and social recovery. Deel, which serves more than 40,000 businesses and 1.5 million contractors across more than 150 countries, introduced stablecoin capabilities in January 2026. The partnership adds a yield layer to that payroll flow while relying on Tempo's roughly $0.001 per-transaction fee model, paid in stablecoins and fully sponsored by Deel for users. The product remains relevant to a broader policy debate around the GENIUS Act's ban on issuer-paid stablecoin interest. Deel's help center says the launch includes a promotional target rate of up to 4% APY, but describes that rate as variable, not guaranteed and driven by market conditions. Deel and Tempo have not disclosed who funds the rate or what share Deel retains.
