Maple - AQRU Pool USDC1
Maple Finance is an on-chain institutional credit marketplace that connects institutional borrowers with on-chain lenders. Founded in 2021 and operating on Ethereum, it has originated over $12 billion in loans to institutional counterparties including crypto trading firms, market makers, and real-world asset originators.
The AQRU Receivables Pool (USDC1) is a real-world asset (RWA) lending pool launched in January 2023. It was managed by AQRU plc — a London-based publicly listed company (AQSE: AQRU) — as the pool delegate, with Intero Capital Solutions as the loan originator.
How the pool works:
- Lenders deposit USDC into the pool via an ERC-4626 vault on Ethereum.
- Intero Capital Solutions identifies US businesses with outstanding IRS tax credits (primarily COVID-era Employee Retention Credits, R&D credits, and renewable energy credits).
- The pool advances USDC to these businesses in exchange for an assignment of the receivable — i.e., the right to collect directly from the IRS.
- The IRS settles the tax credit, and repayment flows back to the pool. Historical data shows 54.8% of loans repaid within 90 days, 31.25% within 91–120 days.
- Yield is passed to USDC depositors at a gross rate of 10–16.2% APY depending on the period.
The pool was designed to run through Q3 2025, aligned with the IRS tax credit receivables pipeline, and is currently closed to new deposits.

Strategy
- Meet eligibility requirements
- Must be an accredited investor (institutional or high-net-worth individual)
- Minimum deposit: $50,000 USDC (reduced from original $250,000)
- Complete KYC/AML verification through Maple's onboarding process
- Deposit USDC into the pool
- Connect wallet at app.maple.finance
- Select the AQRU Receivables Pool and deposit USDC
- Receive pool tokens representing your share of the vault (ERC-4626)
- Earn yield from receivables
- Your USDC is deployed by Intero Capital Solutions to fund IRS tax credit receivables
- Yield accrues as the pool receives repayments and re-deploys capital
- Target gross APY: 10–16.2% (varied over the pool's lifecycle)
- Request withdrawal
- Withdrawals are available in weekly windows (Monday–Thursday) after the initial lockup period
- Withdrawals are queued via Maple's WithdrawalManager contract and subject to available liquidity
Yield Source
The AQRU Pool's yield is entirely sourced from real-world assets — specifically, US IRS tax credit receivables — rather than crypto-native mechanisms like liquidity provision or staking.
The yield generation process:
- Receivables financing: Intero Capital Solutions advances USDC to businesses that have filed for IRS tax credits (Employee Retention Credits, R&D credits, etc.) but have not yet received payment. These businesses typically wait 3–12 months for IRS settlement.
- Discount purchase: The pool purchases the receivable at a discount to face value. The spread between advance price and the IRS settlement amount is the yield.
- Revolving structure: As the IRS repays businesses, those funds flow back into the pool and are re-deployed to new receivables — creating a revolving cycle. The pool processed over $45 million in revolving loans across 382 receivables.
- Yield sustainability: The IRS receivables pipeline was finite. The pool was designed to wind down by Q3 2025 as the COVID-era Employee Retention Credit program ran off.
Because yield is driven by real-world credit rates rather than crypto funding rates, it is structurally uncorrelated with crypto market conditions — a key design goal of the AQRU pool.
Strategy Limits
Deterministic Constraints
- Pool lifecycle: The AQRU pool was designed to wind down by Q3 2025 with the expected end of the IRS tax credit receivables pipeline. It is currently closed to new deposits.
- Accredited investor gate: Participation requires accredited investor status with a $50,000 minimum — access is fundamentally restricted.
- Weekly withdrawal windows: Liquidity is not continuous; withdrawals are queued in weekly windows and are subject to available cash in the pool.
Probabilistic Constraints
- IRS settlement delays: The IRS can take longer than modeled to process tax credit claims, extending the duration of receivables beyond the 3–5 month target and reducing effective yield.
- Counterparty concentration: All loan origination flows through a single counterparty (Intero Capital Solutions). Any operational failure or misconduct by Intero directly impairs the pool.
- Regulatory changes: US legislative or IRS rule changes could reduce or eliminate the tax credit receivables pipeline, removing the yield source.
- Off-chain enforcement uncertainty: Unlike crypto-collateralized loans that can be liquidated on-chain, recovering on a failed IRS receivable requires legal action — slower and less certain.
Underlying Assets/Allocations

100% USDC deposits deployed against US IRS tax credit receivables via Intero Capital Solutions. Collateral is entirely off-chain; no on-chain asset breakdown is available.
Risk Analysis
Potential Risks
Based on Maple Finance documentation and the AQRU pool structure, the following risks may result in partial or total loss of deposited funds:
- Credit default risk — Intero Capital Solutions or its underlying borrowers may fail to repay, with no on-chain liquidation mechanism available (precedent: Orthogonal Trading 80% loss)
- Off-chain enforcement failure — Recovery on defaulted IRS receivables requires legal action in US courts; outcomes are uncertain and time-consuming
- IRS program risk — Regulatory changes or IRS delays in processing tax credits reduce receivable value and extend loan duration beyond models
- Pool delegate failure — If AQRU plc or Intero Capital Solutions ceases operations, the pool has no alternative originator and recovery becomes complex
- Smart contract risk — Despite multiple audits, vulnerabilities in Maple's contracts or the WithdrawalManager could expose depositor funds
- Liquidity risk — Withdrawal queues during stress could trap capital for extended periods
- Pool wind-down risk — As the pool closes, remaining receivables may take longer to settle than anticipated, delaying final redemptions
Risk Analysis (3rd Parties)
Summary
The Maple AQRU Pool USDC1 was a first-of-its-kind RWA lending pool that brought IRS tax credit receivables on-chain. It offered attractive gross yields (10–16.2%) uncorrelated with crypto markets, but with significant off-chain credit and enforcement risks. The pool has wound down in line with its Q3 2025 design timeline.
Maple Finance as a protocol has matured significantly since its 2022 defaults, now ranking among the top RWA lending protocols by TVL and revenue. However, the AQRU pool's high dependency on a single loan originator, off-chain collateral enforcement, and Maple's historical default track record make this a high-risk strategy suitable only for sophisticated investors with limited allocation.
DeFiSafety reviewed Maple V2.0 in March 2023 and awarded a 92% score, one of the highest in the DeFi lending category.

Smart Contract Audits
Maple has conducted 14+ independent audits since December 2022, covering each major protocol release. Auditors include Trail of Bits, Spearbit, Three Sigma, 0xMacro, Sherlock, Dedaub, and Sigma Prime. An active Immunefi bug bounty program offers up to $500,000 for critical findings.
Historical Default Events
December 2022 — Orthogonal Trading ($36M default)
Orthogonal Trading defaulted on 8 Maple loans totaling $36 million (~30% of all active loans at the time) after concealing FTX-related losses. Depositors in affected pools faced up to 80% losses. Orthogonal was subsequently placed into provisional BVI court liquidation.
June 2022 — Babel Finance ($10M default)
Babel Finance failed to service a $10 million Maple loan. Creditors suffered a $7.9 million loss, representing a ~3.2% haircut on the affected pool.
Post-2022 Recovery
Following the 2022 defaults, Maple redesigned its underwriting standards, introduced stricter KYC, and pivoted toward over-collateralized institutional lending. The protocol reported a 99% repayment rate post-restructuring and grew TVL to $4B+ by 2025, ranking 4th among RWA projects by revenue ($13.4M in February 2026).
