# sUSDp Factsheet

sUSDp is the yield-bearing version of USDp. Depositing USDp into the Savings Module returns sUSDp, a liquid ERC-4626 share that grows with the protocol's revenue. This sheet gives the facts a listing or integration team needs first.

## Key facts

| Field | Value |
| --- | --- |
| Name | Savings USDp |
| Ticker | sUSDp |
| Type | Yield-bearing savings token |
| Standard | ERC-4626 vault share (ERC-20 compatible) |
| Underlying | [USDp](/resources/factsheets/usdp); the share price rises as yield accrues, so 1 sUSDp is worth more than 1 USDp over time |
| Issuer | Parallel V3, a DAO-governed protocol built by Cooper Labs |
| Chains | 4 chains: Ethereum, Base, HyperEVM, Avalanche. A Sonic deployment is being wound down (exit only). See [USDp contract addresses](/developers-hub/contract-addresses/parallel-v3/usdp) |
| Canonical contract (Ethereum) | [0xd3a452B305C8285c0Dd7b8537665c734d3D279eF](https://etherscan.io/address/0xd3a452B305C8285c0Dd7b8537665c734d3D279eF#code) |
| Yield source | 90% of the fees generated by the USDp codebase. Under current parameters the return on the assets backing USDp is, in practice, what funds the rate (pending confirmation by the protocol). See [Fee Distribution](/products/parallel-v3/stablecoins-and-savings/usdp-and-susdp/fee-distribution) |
| Rate | Set by DAO-approved [keepers](/security/keepers) (currently Cooper Labs), hard-capped at 35.00% by the DAO. Live rate on the [Earn page](https://app.parallel.best/earn) |
| Fees | No deposit, withdrawal or staking fee. See [Fees](/products/parallel-v3/fees) |
| Lock-up | None. sUSDp is liquid and can be transferred, lent or used as collateral at any time |
| Governance role | None. sUSDp carries no voting power; the Savings Module parameters are set by the [DAO](/products/parallel-v3/governance) |
| Licensing | Savings contracts are part of the Parallelizer repository, BUSL 1.1. See [Licensing](/products/parallel-v3/licensing) |

## How it works

The [Savings Module](/products/parallel-v3/how-it-works/savings-module) is a plain ERC-4626 vault: you deposit USDp and receive sUSDp, and yield accrues to the share price from the first block. The rate reflects the return the protocol earns on the USDp backing across the Parallelizer, Flashloan and Bridging modules, and keepers adjust it under the 35.00% cap so no single actor can inflate it. Holding sUSDp adds no trust assumption beyond holding USDp: there is no external strategy, no lending counterparty and no lock-up. Redeeming returns USDp at the current share price without slippage.

## Backing and risk

sUSDp is backed one for one by the USDp held in the vault, so it inherits USDp's backing and its risks: a depeg of a backing asset, an oracle failure or a bridge failure. The USDp reserves are auditable live on the [Proof of Solvency](/security/proof-of-solvency) page. On top of that, the savings rate depends on keepers, which is why the DAO caps it. Read [Risks](/security/risks) for the full list, including the Savings fix audits listed on the [Audits](/security/audits) page.

## Where to get it

* **Deposit USDp** on Ethereum, Base, HyperEVM or Avalanche: [app.parallel.best/earn](https://app.parallel.best/earn)
* **Withdraw** to USDp at any time from the same page
* **Get USDp first**: mint at [app.parallel.best/mint](https://app.parallel.best/mint) or bridge at [app.parallel.best/bridge](https://app.parallel.best/bridge)
* **Step-by-step**: [How to earn yield on USDp with sUSDp](/resources/user-guides/stake-usdp-into-susdp)

sUSDp is not bridged by the protocol. Bridge USDp, then deposit on the destination chain.

## Integrate it

* [Savings Module integration](/developers-hub/parallel-v3/build-on-parallel/savings-module-integration): deposit, redeem and read the rate with the standard ERC-4626 interface
* [USDp contract addresses](/developers-hub/contract-addresses/parallel-v3/usdp): the sUSDp vault on each chain
* [Subgraphs](/developers-hub/parallel-v3/offchain-tools/subgraphs) for rates, deposits and share-price history; [Dune](/developers-hub/parallel-v3/offchain-tools/dune) dashboards are planned
* [MCP server](/agents/mcp): live on 5 chains with 36 tools, giving any AI client the live savings rate and ready-to-sign deposit transactions
* [x402](/agents/x402): sUSDp is accepted by Parallel's x402 facilitator (gas sponsored on Base, HyperEVM, Avalanche; Ethereum supported but not sponsored). Agents can pay in USDp, USDC or sUSDp
