Onboard syrupUSDT to Aave V3 Core Instance
01Summary
Proposal to onboard syrupUSDT to Aave V3 Core Instance with a 50 million supply cap, very low LTV (0.05%), enabled as collateral with flashloan support, and inclusion in a stablecoin e-mode category. Borrowing is effectively disabled with only 1 unit borrow cap.
- Type
- protocol addition
Key changes
- Onboard syrupUSDT token to Aave V3 Core Instance as collateral asset(high)
- Set supply cap at 50,000,000 syrupUSDT with borrow cap of 1 (effectively disabling borrowing)(high)
- Configure risk parameters with very low LTV of 0.05% and LT of 0.1% in standard mode(high)
- Add syrupUSDT to stablecoin e-mode with 90% max LTV and 92% liquidation threshold(high)
- Enable flashloan functionality for syrupUSDT(medium)
- Set oracle with 7-day minimum snapshot delay and 8.45% max yearly growth cap(medium)
- Establish 0xac140648435d03f784879cd789130F22Ef588Fcd as emission admin for syrupUSDT and aToken(low)
Notable concerns
- Very restrictive collateral parameters (0.05% LTV) indicate high caution regarding syrupUSDT risk
- Borrowing is effectively disabled with 1 unit borrow cap despite asset being added to protocol
- Token is collateral-only in standard mode, restricted to e-mode for borrowing functionality

02Description
Simple Summary
This proposal seeks to onboard syrupUSDT to Aave V3 Core Instance.
Motivation
With the recent approval of syrupUSDC on the Core Instance following BGD Labs’ updated technical review and syrupUSDT on the Plasma Instance, we propose to expand this asset to other networks beginning with the Core Instance. We propose this under the Direct to AIP framework.
There is significant demand for syrupUSDT to be used in Aave, and with the Core Instance having the deepest stablecoin liquidity we believe this is the logical next instance on which to onboard syrupUSDT.

03Mismatch analysis
The proposal follows the standard Aave V3 'Direct to AIP' governance pattern: a single on-chain action that calls execute() on a dedicated payload contract, whose internal Solidity logic (linked in the 'Implementation' reference) performs the actual reserve listing, oracle wiring, e-mode configuration, and emission admin assignment described in the prose. Because the decoded calldata for this action is just a parameterless execute() call, none of the specific numeric risk parameters (LTV, LT, caps, rates, oracle addresses, e-mode settings, emission admin address) can be independently verified against on-chain calldata values in this data set — they are only verifiable by inspecting the payload contract's bytecode/source, which is outside the scope of the decoded action shown here. This is a well-established, low-risk pattern for Aave listings and does not itself indicate any inconsistency; there is nothing in the decoded action that contradicts, omits, or exceeds what the description claims. No value mismatches, target mismatches, or hidden actions can be identified from the given data. Confidence is set to medium rather than high because the actual parameter-level verification is not possible from the single opaque execute() call, but the assessment remains 'consistent' since no evidence of divergence exists and this proposal structure is standard practice for this contract type.
