Deep Dive
1. Multichain Deployment via LayerZero (15 August 2025)
Overview: USD0 expanded to TAC blockchain using LayerZero’s Omnichain Fungible Token (OFT) standard, enabling native cross-chain transfers via InterportFi.
This upgrade simplifies bridging USD0 and its yield-bearing variant USD0++ across chains without third-party custodians. The OFT standard reduces slippage and increases interoperability with TAC-based DeFi protocols like Curve pools.
What this means: This is bullish for USD0 because cross-chain accessibility could increase utility and liquidity. Users benefit from cheaper, faster transfers between ecosystems. (Source)
2. TAC Vault Migration (16 July 2025)
Overview: The Ethereum-based TAC Vault migrated to TAC mainnet, automating user deposits and rewards without requiring manual action.
The migration involved snapshotting user balances and retroactively applying rewards. The vault now serves as a gateway to TAC’s growth, offering exposure to farming incentives and governance benefits.
What this means: This is neutral for USD0 as it streamlines user experience but doesn’t directly alter tokenomics. Existing holders retain yield opportunities, while new users gain simplified access to TAC integrations. (Source)
3. Locked Staking Rewards (7 July 2025)
Overview: Proposal UIP-9 overhauled staking mechanics, requiring USUALx (governance token) locks of 1–12 months for boosted USD0 rewards.
Locking USUALx for 12 months now provides an 8× multiplier on weekly USD0 payouts, aligning incentives with long-term protocol alignment.
What this means: This is bullish for USD0 because longer lock-ups reduce sell pressure on USUALx, potentially stabilizing its value. Users earn higher yields for committed stakes, reinforcing protocol loyalty. (Source)
Conclusion
Usual USD’s codebase prioritizes interoperability (TAC/LayerZero), user experience (vault migration), and protocol loyalty (staking boosts). These updates aim to deepen USD0’s DeFi integration while incentivizing long-term participation.
Could cross-chain expansions like TAC pave the way for USD0 to capture more real-world asset (RWA) use cases?
