Why it matters?

This bill could mark the first serious attempt to treat stablecoins as payment tools rather than speculative assets. If adopted, it may accelerate real-world crypto usage while reshaping investor behavior across staking and DeFi lending markets.

Stablecoin Payments Get A $200 De Minimis Exemption

The draft proposes a $200 tax exemption for regulated stablecoin payments used to purchase goods and services. The exemption does not apply to investment gains and is framed strictly as an administrative simplification. Lawmakers are still evaluating whether an annual aggregate cap should apply to prevent repeated use from eroding tax collection.

The Treasury Department would receive authority to introduce anti-abuse rules. These may target coordinated transactions, related-party arrangements, and recordkeeping requirements. Additional guidance could also clarify cost basis allocation and gain characterization when the exemption does not apply.

Clear Tax Treatment For Digital Asset Lending

Another key section addresses digital asset lending. The bill extends nonrecognition treatment only to true lending of liquid and fungible digital assets. Lenders must retain the right to receive identical property back, ensuring the transaction does not function as a sale or disposal.

The framework explicitly excludes NFTs, illiquid tokens, thinly traded assets, tokenized securities, and synthetic or derivative-based instruments. Treasury guidance would aim to prevent disguised sales, basis shifting, and other tax avoidance structures within DeFi lending models.

Staking And Mining Rewards May Qualify For Tax Deferral

The proposal defines staking and mining as transaction validation activities on a cryptographically secured shared ledger. Taxpayers could elect to defer income recognition on rewards until the end of the fifth taxable year following receipt.

This approach reduces immediate tax pressure on long-term network participants. It also differentiates infrastructure contributors from short-term speculative actors, potentially influencing on-chain participation trends.

Overview

Avalon Labs is designed to help Bitcoin holders unlock liquidity, borrow, and earn yield without selling their BTC. Its foundation includes BTC-collateralized yield-bearing CDPs (USDa), CeDeFi lending (blending CeFi liquidity with DeFi models), DeFi lending pools, and complementary services. 

Investors & Partners

Avalon Finance is backed by top investors and partners including YZi Labs, Framework, Kenetic, Mirana, SNZ Holding, Matrixport, Antalpha, UTXO, CEiC, Summer Ventures, Comma 3 Ventures, Geekcartel, ViaBTC, Trinito, Presto, Marblex, Paka, DOMO (BRC20 creators), Taiko, and the BNB Chain MVB incubation program. 

Key highlights: 

• Institutional partners like YZi Labs and BNB Chain MVB program. 
• Token listings on Bybit, Binance Alpha, and Bithumb. 
• Notable co-founder: Venus Li. 

Vision

Avalon’s vision is to evolve Bitcoin beyond “digital gold” into a yield-generating, credit-enabling asset active in lending markets. With BTC-backed stablecoins, CeDeFi liquidity, and multi-chain lending, Avalon seeks to integrate BTC into everyday and institutional finance. 

How It Works (Products) 

USDa (CeDeFi CDP): A BTC-collateralized yield-bearing stablecoin, claimed as the world’s first and largest BTC-CDP. 

• USDaLend: Borrowing and lending protocols based on USDa. 
• CeDeFi Lending: Hybrid model merging DeFi with institutional CeFi liquidity providers. 
• DeFi Lending (Isolated Pools): Risk-controlled lending pools, supporting collateral types like LSDFi. 
• Flow: Users lock BTC → mint USDa or borrow → use in Avalon products (USDaLend, DeFi lending). 

Governance — AVL & sAVL 

• AVL: Governance token, total supply 1B, used for incentives, fee reductions, and governance. 
• sAVL (staked AVL): Earned by staking AVL; grants governance rights, emission shaping, and fee rebates. 

Roadmap Highlights 

• TVL milestones ($500M → $800M → $1B+). 
• Launch of USDa. 
• Fixed-rate borrowing. 
• Multi-chain expansion. 
• AVL token listings (from Feb 2025). 

Token Utility

AVL and sAVL provide: 

• Governance power. 
• Access to ecosystem benefits (AVL Lend, fee rebates). 
• Yield rewards through staking. 
• Borrowing cost reductions. 

Tokenomics 

• Total Supply: 162.25M AVL 
• Circulating Supply: 161.68M AVL 
• Max Supply: 1B AVL 

Distribution

• Community Incentive: 28% (48m vesting) 
• Airdrop: 20% (50% TGE, rest 6m) 
• Ecosystem & Treasury: 15% (48m vesting) 
• Team: 10% (18m cliff, 18m linear) 
• Advisors: 4% (12m cliff, 12m vesting) 
• Initial Liquidity: 4% (75% TGE, 3m vesting) 
• Investors: 19% (12m cliff, 12m vesting) 

Ecosystem Components 

• USDa: BTC-backed stablecoin 
• USDaLend: Lending protocols 
• CeDeFi Lending: Hybrid liquidity model 
• DeFi Lending / Isolated Pools: Risk-managed lending 
• AVL & sAVL: Governance, staking, rewards 
• Explorer, docs, and audit reports 

Key Features & Advantages 

• BTC-backed CDP (USDa): Yield-bearing stablecoin on Bitcoin. 
• CeDeFi hybrid model: CeFi liquidity + DeFi innovation. 
• Fast TVL growth & multi-chain expansion. 
• Audits & Security: Contracts audited by SlowMist, BlockSec, Salus.

Aave’s Deployment on Aptos: Supported Assets and Protocol Strength 

Aave enters Aptos to extend its multichain strategy across different ecosystems. At launch, the protocol supports native USDC, USDT, APT, and sUSDe. Aptos Foundation attracts users through incentive programs, ensuring faster growth in adoption. 

The Block’s data shows Aave managing over $50 billion in net deposits and nearly $37 billion in total value locked. The protocol enables users and institutions to earn interest on deposits. It also lets them borrow crypto against collateral and issues the overcollateralized GHO stablecoin. 

Chainlink oracles secure price data, strengthening transparency and reliability in lending markets. This integration gives users confidence in safe and resilient borrowing activity. 

Aptos and Aave: Building a Shared Vision 

Aptos runs as a proof-of-stake Layer 1 blockchain built with Move, a Rust-based smart contract language. The network emphasizes low-latency finality and high throughput to attract developers. 

Aave Labs re-implemented Aave V3 in Move and developed a new SDK and front-end. Chaos Labs and LlamaRisk created market risk parameters. Zellic, Ottersec, SpearBit, and Certora conducted security reviews. Aave also launched a $500,000 bug bounty program paid in GHO. 

The Aptos ecosystem currently holds around $1.3 billion in stablecoins, dominated by USDT. Only 8.1% of APT supply is in liquid staking tokens, while 76% remains directly staked. Aave and Aptos see this gap as an opportunity to unlock new collateral markets. 

Ultimately, Aave’s launch on Aptos opens a new chapter in DeFi expansion. Developers gain direct access to Aave’s lending infrastructure with full tooling support. Users benefit from lending, borrowing, oracle-secured markets, and incentive programs at launch. In the coming months, both teams plan to add more assets, refine risk settings, and strengthen security through ongoing audits.

The post Aave Debuts on Aptos with USDC, USDT, APT and sUSDe appeared first on Coin Engineer.

On April 26, a hacker siphoned around $5.7 million USDC and 1,200 SOL by executing a series of undercollateralized loans, co-founder Mary Gooneratne said.

Following the attack, Loopscale announced it had re-enabled loan repayments, balance top-ups, and loop closing. However, “all other app functionalities, including Vault withdrawals, remain temporarily restricted” as investigations continue.

Gooneratne clarified that only the USDC and SOL vaults were impacted, with the losses representing about 12% of the protocol’s total value locked (TVL).

DeFi Sector Continues to Face Cyber Threats!

The Loopscale team emphasized that they are fully mobilized to investigate the incident, recover the stolen funds, and protect users.

In the first quarter of 2025, hackers stole over $1.6 billion in cryptocurrencies from exchanges and on-chain smart contracts. Over 90% of these losses were attributed to the $1.5 billion hack on the centralized exchange ByBit, reportedly orchestrated by North Korea’s Lazarus Group.

Loopscale’s Innovative Lending Model

Loopscale officially launched on April 10 after a six-month closed beta. The platform aims to boost capital efficiency by directly matching lenders and borrowers.

Unlike traditional DeFi platforms like Aave, Loopscale operates on an order book model rather than liquidity pools.

Its main USDC and SOL vaults currently offer annual percentage rates (APRs) exceeding 5% and 10%, respectively. It also supports lending markets for tokens such as JitoSOL, BONK, and looping strategies for over 40 token pairs.

Loopscale holds approximately $40 million in total value locked and has attracted over 7,000 lenders, according to researcher OurNetwork.
