How Does Avalon USDa Work?
Avalon USDa lets you lock Bitcoin as collateral and mint a dollar-pegged stablecoin without selling your BTC. USDa is unique because it offers a 1:1 USDT redemption guarantee backed by a $2 billion credit line, meaning you can always swap USDa for USDT at par value. The protocol accepts various forms of BTC including wrapped and liquid staking versions.

Core Mechanisms
Stablecoin/CDP/BTC-Backed
NovelUSDa: BTC-backed CDP stablecoin where users deposit BTC and BTC LSTs (uniBTC, LBTC, etc.) as collateral to mint USDa
Novel BTC-native CDP stablecoin. Unlike ETH-backed CDPs, BTC collateral lacks native smart contract capability, requiring CeDeFi bridge infrastructure to custody and manage collateral.
Stablecoin/Peg Maintenance/USDT Redemption Floor
Novel1:1 USDa-to-USDT redemption guarantee backed by a $2B institutional credit line
Novel peg mechanism using off-chain credit line to guarantee 1:1 USDT redemption. Creates hard peg floor but introduces massive counterparty risk on the credit facility provider.
Lending/Collateral Models/Multi-Asset BTC Collateral
Accepts multiple BTC derivatives as collateral: native BTC, uniBTC, LBTC, SolvBTC, and other BTC LSTs
Multi-BTC-derivative collateral acceptance increases flexibility but introduces correlation risk — all collateral types depend on BTC price, and some (uniBTC) have their own exploit history.
Lending/Oracle Dependencies/Price Feed Oracle
Redstone oracle as primary price feed for BTC-USD market securing USDa across all supported networks
Redstone oracle dependency for BTC price feeds. Single oracle provider creates concentration risk. Oracle accuracy is critical for liquidation timing during BTC volatility.
Stablecoin/Liquidation/High-Frequency Liquidation
High-frequency automated liquidation engine for undercollateralized BTC-backed positions
Automated liquidation with high-frequency monitoring. BTC's cross-chain nature means liquidation must coordinate across CeDeFi bridge infrastructure, adding latency risk.
Cross-System/CeDeFi/Custodial Bridge
CeDeFi infrastructure bridging BTC collateral from Bitcoin chain to smart contract platforms for CDP operations
CeDeFi bridge custody model moves BTC collateral across chain boundaries. Introduces custodial counterparty risk absent in native smart contract CDPs like MakerDAO.
How the Pieces Interact
The peg floor depends entirely on the credit facility provider honoring the $2B commitment. If the credit provider faces liquidity stress, defaults, or revokes the facility, USDa's peg floor disappears and market-based depeg begins instantly.
BTC collateral must cross custodial boundaries via CeDeFi infrastructure. A custodian failure, bridge exploit, or key compromise could result in loss of BTC collateral backing USDa, creating protocol-wide undercollateralization.
Accepting BTC LSTs like uniBTC (which suffered a $2M exploit in 2024) as collateral imports the security failures of underlying LST protocols. An LST depeg or exploit drains USDa's effective collateral backing.
Without a supply cap, USDa can expand without limit during bull markets when collateral values are high. In a BTC crash, the expanded supply faces mass liquidation pressure that may overwhelm the liquidation engine and credit facility simultaneously.
Single oracle provider (Redstone) for BTC pricing creates concentration risk. During BTC flash crashes, oracle latency combined with cross-chain liquidation coordination delays could allow positions to become undercollateralized before liquidation executes.
What Could Go Wrong
- USDa's 1:1 USDT redemption guarantee backed by a $2B credit line introduces massive off-chain counterparty risk — credit line failure breaks the peg floor
- BTC-backed CDP with CeDeFi bridge model means Bitcoin collateral crosses custodial boundaries, creating opaque custody chain risk
- No supply cap on USDa creates unlimited expansion risk; if demand for borrowing exceeds prudent collateral ratios, systemic undercollateralization can develop
Credit Facility Default Triggering USDa Depeg
ModerateTrigger: The institutional credit facility provider backing USDa's $2B USDT redemption guarantee faces liquidity stress or defaults during a simultaneous BTC market crash
- 1.BTC drops 30%+ triggering wave of USDa redemptions as holders seek USDT via the 1:1 guarantee — Credit facility draws accelerate as redemption volume spikes; provider faces liquidity strain
- 2.Credit facility provider delays or pauses USDT disbursements due to liquidity constraints — USDa redemption mechanism breaks; market realizes the peg floor is not guaranteed
- 3.USDa trades at 5-15% discount on secondary markets as confidence in the USDT redemption collapses — Panic selling accelerates; CDP holders rush to close positions, flooding liquidation engine with sell orders
- 4.BTC collateral liquidations overwhelm the system; bad debt accumulates faster than stability mechanisms can absorb — USDa enters potential death spiral as both the credit backstop and collateral backing fail simultaneously
