What is $MUSD?
$MUSD is a yield-bearing stablecoin. When you swap USDC for $MUSD, your USDC is held in reserve and generates yield through our vault strategies. This yield accrues to $MUSD holders automatically.
Key Properties
- Fully backed: Every $MUSD is backed by real USDC in reserve
- Always redeemable: Swap $MUSD → USDC anytime on the Memento dApp
- Yield-bearing: Earns ~8-10% APY from vault reserves automatically
- Stakeable: Stake for $sMUSD to earn additional yield from Memento Engine
How to Get $MUSD
Connect Your Wallet
Connect a Solana wallet with USDC to the Memento dApp. Make sure you have some SOL for transaction fees.
Navigate to Swap
Go to the $MUSD swap interface on the Memento dApp.
Enter Amount
Enter the amount of USDC you want to swap for $MUSD.
Confirm Swap
Review the transaction details including the 1% swap fee. Confirm the transaction in your wallet.
Start Earning
Your $MUSD will appear in your wallet and immediately start earning base yield from vault reserves. Optionally stake in Memento Engine for additional returns.
$MUSD Backing & Yield
Every $MUSD is backed 1:1 by real USDC. The backing is split between liquid reserves and productive deployment in Memento Vaults:
| Component | Allocation | Purpose |
|---|---|---|
| Liquid USDC Reserve | 40% | Held in qualified custodian for instant redemptions (~4% APY) |
| Memento Vaults | 60% | Deployed in vault strategies earning 9-14% APY |
How Yield is Generated
The 60% of reserves deployed in Memento Vaults generates yield through our curated strategies (basis trading, dividend arbitrage, stablecoin lending, etc.) earning 9-14% APY. Combined with the 40% liquid reserve earning ~4%, this results in approximately 8-10% APY on your $MUSD holdings. The 40% liquid reserve ensures there is always sufficient liquidity for instant redemptions.

Swap Fees
A 1% fee applies to both directions of the swap:
| Action | Fee | Recipient |
|---|---|---|
| USDC → $MUSD | 1% | $MM Buyback & Burn |
| $MUSD → USDC | 1% | $MM Buyback & Burn |
$MM Buyback & Burn
100% of swap fees are used to buy $MM tokens from the open market and burn them permanently. This creates deflationary pressure on $MM:
- More $MUSD adoption → More swap volume
- More swap volume → More fees collected
- More fees → More $MM burned
- $MM supply decreases → Value accrues to remaining holders
$MUSD vs $sMUSD
Both tokens earn yield, but from different sources:
| Token | Type | Yield | Source |
|---|---|---|---|
| $MUSD | Yield-bearing stablecoin | ~8-10% APY | Vault reserves (60% in 9-14% vaults) |
| $sMUSD | Staked $MUSD | 15-17% APY total | $MUSD yield + Memento Engine |
Two Layers of Yield
$MUSD earns base yield automatically from the 60% of reserves deployed in Memento Vaults. To earn additional yield, you can stake your $MUSD in Memento Engine to receive $sMUSD. The staked version earns extra returns from institutional commodity finance (trade finance, collateralized lending, producer bonds), bringing the total APY to 15-17%.

Risk Disclosures
Users should understand the risks associated with holding $MUSD:
Smart Contract Risk
$MUSD relies on smart contracts for minting, redemption and yield distribution. While audited by reputable firms, smart contracts may contain undiscovered vulnerabilities that could result in loss of funds.
Vault Strategy Risk
The 60% of reserves deployed in Memento Vaults is subject to strategy-specific risks including market volatility, counterparty risk and liquidity risk. In adverse conditions, vault yields may decrease or principal may be impacted.
USDC Dependency
$MUSD is backed by USDC. If USDC experiences a de-peg event or issuer (Circle) faces regulatory or operational issues, $MUSD value could be affected.
Regulatory Risk
Changes in cryptocurrency regulations could impact the operation of $MUSD or its availability in certain jurisdictions.
Not FDIC Insured
Technical Implementation
$MUSD is implemented as an SPL token on Solana with yield-bearing mechanics:
| Property | Value |
|---|---|
| Token Standard | SPL Token |
| Blockchain | Solana |
| Decimals | 6 (same as USDC) |
| Yield Mechanism | Rebasing (balance increases) |
| Transferable | Yes |
| Program Address | TBA (launching Q1 2026) |
Yield Distribution
$MUSD uses a rebasing mechanism where holder balances increase proportionally as yield accrues. This happens automatically without any user action required. The rebase occurs daily based on vault performance.
Security Audits
$MUSD smart contracts will undergo multiple security audits before launch. Audit reports will be published publicly. We maintain an ongoing bug bounty program for responsible disclosure.
