+title: "Onboard syrupUSDC to Aave V3 Core Instance"
+author: "Aavechan Initiative @aci"
+discussions: "https://governance.aave.com/t/arfc-onboard-syrupusdc-to-aave-v3-core-instance/22456"
+snapshot: "https://snapshot.org/#/s:aavedao.eth/proposal/0xf5951af5d6d7d70be998a72c531708db3ff9c46b033e3e27bfd59fb87542d0ea"
+---
+
+## Simple Summary
+
+This proposal seeks to onboard syrupUSDC — a USDC-based yield-bearing token issued by Maple Finance — as a collateral asset on Aave V3 Core Instance. syrupUSDC is built on top of Maple's infrastructure and offers access to overcollateralized, fixed-rate institutional loans, which provide high and consistent yields to DeFi users.
+
+Maple, launched in 2021, is an on-chain asset manager whose team has decades of traditional finance and crypto experience. As of June 2025, Maple has $2.3b in AUM. Maple combines deep capital markets expertise with DeFi innovation to offer digital asset lending and yield products.
+
+## Motivation
+
+Onboarding syrupUSDC to Aave V3 Core Instance provides:
+
+- New Token Type: A new collateral option backed by real yield from fixed-rate institutional lending strategies
+- AAVE TVL: Maple has a large network of institutional capital allocators, ready to allocate $500M+ USDC/USDT into syrupUSDC if it is available on Aave as collateral to loop it and get to their hurdle rates.
+- Higher Rates and Utilization: Increases USDC rates and utilization due to strong expected borrower demand.
+- Growth Incentives: Maple has $250k of incentives available to bootstrap the growth for Aave users.
+
+The Aave and Maple partnership will enable:
+
+- New Yield Opportunities: Commercial alignment with Maple's large institutional network, unlocking additional yield generation opportunities for Aave.
+- GHO Adoption: Maple can help with growing other strategic priorities for Aave, including GHO adoption. E.g., GHO lending to institutions.
+- Future Collaboration: Future asset listings, including the Maple liquid yielding Bitcoin asset.
+
+## Specification
+
+It's a USDC-based, yield-bearing token whose principal and yield are backed by the secured lending strategy of Maple. (More details below).
+
+Technical details: ERC-4626 token standard built on top of Maple's smart contracts.
+High Yield. Maple has a track record of generating consistently high underlying yields of 7-15% net APY.
+
+Loans are fully collateralized by digital assets ensuring lending positions are protected, even if borrowers default or asset prices fall. More on: https://app.maple.finance/earn.
