On October 21st, TRON's decentralized stablecoin, USDD, officially launched on BNB Chain and launched the sUSDD Merkl limited-time airdrop. This event, exclusively co-organized by Merkl, a decentralized incentive distribution platform, is open to all users on both Ethereum and BNB Chain.
From October 21st to October 26th, 2025 (SGT), users holding sUSDD during this promotional period will receive a 12% base annualized yield (Base APY) and receive a limited-time airdrop bonus of 5,000 USDD. This promotion aims to incentivize long-term holding, increase ecosystem lock-up volume, and enhance user engagement, providing DeFi users with a stable and sustainable income experience.
Hold sUSDD and enjoy double benefits: 12% fixed annualized return + additional 5,000 USDD airdrop
sUSDD is an interest-bearing token within the USDD ecosystem, with automatically compounded returns and the ability to unlock them at any time. Users can deposit USDD into USDD Savings to instantly mint sUSDD, which automatically begins accruing interest, with a base yield of up to 12% annualized.
This limited-time airdrop event launched in partnership with Merkl will further increase user benefits. Details of the event are as follows:
- Event period: October 21, 2025 to October 26, 2025 (SGT)
- Total reward pool: 5,000 USDD
- Chain Allocation: Ethereum and BNB Chain each have a 2,500 USDD reward pool
- Single household limit: no more than 3% of the annualized return of sUSDD holdings
- Rewards distribution: After the event ends, qualified users can directly receive rewards through the Merkl platform
Users simply need to hold sUSDD during the event period to automatically qualify. The Merkl platform will snapshot user holdings during the event period and calculate and distribute rewards based on on-chain data, ensuring a fair, transparent, and traceable process.
The participation process is as follows:
1. Go to the official USDD PSM page and exchange USDT or USDC for USDD:
- Ethereum: http://app.usdd.io/eth/psm
- BNB Chain: http://app.usdd.io/bsc/psm
2. Deposit the USDD you redeem into USDD Savings to obtain interest-bearing tokens (sUSDD):
- Ethereum: http://app.usdd.io/eth/earn
- BNB Chain: http://app.usdd.io/bsc/earn
3. Ensure you hold sUSDD until the end of the promotion to automatically qualify for the Merkl snapshot.
4. After the event ends, go to the Merkl platform to claim your rewards (supports Ethereum and BNB Chain):
- Ethereum: https://app.merkl.xyz/opportunities/ethereum/ERC20LOGPROCESSOR/0xC5d6A7B61d18AfA11435a889557b068BB9f29930
- BNB Chain: https://app.merkl.xyz/opportunities/bsc/ERC20LOGPROCESSOR/0x8bA9dA757d1D66c58b1ae7e2ED6c04087348A82d
The entire activity process is conducted entirely on-chain, with no additional operations or registration required. As long as you hold sUSDD within the specified time, the system will automatically recognize it and include it in the reward calculation.
On-chain incentives upgraded again: continuing the “locking and earning” model
This sUSDD Merkl airdrop builds on the successful collaboration between USDD and Merkl in their previous "Hold USDD" campaign. Through a decentralized smart contract distribution mechanism, all reward data is traceable on-chain, ensuring open, fair, and verifiable incentive distribution.
This activity not only continues the "Hold-to-Earn" design concept but also further optimizes the user experience. Holding sUSDD not only means enjoying stable returns, but also allows for additional airdrops during specific periods, thereby enhancing overall returns.
USDD's simultaneous distribution of rewards across both Ethereum and BNB Chain reflects its commitment to openness and liquidity expansion within a multi-chain ecosystem. By operating simultaneously on two major public blockchains, USDD aims to provide a unified, secure, and transparent earnings experience for more DeFi users.
