{"id":"susda","title":"sUSDa","content":"**sUSDa** is a yield-bearing token developed by Avalon Labs. It functions as the interest-accruing version of USDa, a [stablecoin](https://iq.wiki/wiki/stablecoin) collateralized by [Bitcoin](https://iq.wiki/wiki/bitcoin), and is designed to provide holders with passive returns generated from the [Avalon Finance](https://iq.wiki/wiki/avalon-finance) ecosystem. [\\[1\\]](#cite-id-l0cbfsyGd4) [\\[2\\]](#cite-id-VWcF4G190C)\n\n## Overview\n\nsUSDa is a core component of the Avalon Labs financial ecosystem, which aims to establish an on-chain financial center focused on leveraging [Bitcoin](https://iq.wiki/wiki/bitcoin) as a productive asset. The token represents a user's staked position in the USDa [stablecoin](https://iq.wiki/wiki/stablecoin) pool. By depositing USDa into the Avalon Savings Account or vault, users receive sUSDa, which is designed to increase in value over time as it accrues yield. This mechanism allows holders of the USDa stablecoin to earn passive income without relinquishing their exposure to a dollar-pegged asset. [\\[3\\]](#cite-id-of6YLjgUkf) [\\[4\\]](#cite-id-Ki3Y3LRh8a)\n\nThe parent project, Avalon Labs, operates on a Centralized-Decentralized Finance ([CeDeFi](https://iq.wiki/wiki/cedefi-centralized-decentralized-finance)) model. This hybrid approach seeks to combine the security and liquidity of centralized financial institutions with the transparency and innovation of decentralized finance. The ecosystem is built around transforming [Bitcoin](https://iq.wiki/wiki/bitcoin) from a passive store of value into an active financial instrument for lending, borrowing, and yield generation. The USDa [stablecoin](https://iq.wiki/wiki/stablecoin) serves as the primary medium of exchange and liquidity within this system, while sUSDa acts as the primary vehicle for value accrual and yield distribution to participants. [\\[2\\]](#cite-id-VWcF4G190C)\n\n## History\n\nAvalon Labs announced the launch of its [Bitcoin](https://iq.wiki/wiki/bitcoin)-backed [stablecoin](https://iq.wiki/wiki/stablecoin), USDa, and its associated yield-bearing token, sUSDa, on November 11, 2024. The launch was positioned as a solution to unlock liquidity for Bitcoin holders, allowing them to borrow against their assets without selling them. At the time of the announcement, Avalon Labs reported having already issued over $1.2 billion in BTC-backed loans, establishing a track record in the Bitcoin Finance ([BTCFi](https://iq.wiki/wiki/btcfi)) sector. [\\[2\\]](#cite-id-VWcF4G190C)\n\nIn October 2025, Avalon Labs expanded the utility of sUSDa through a strategic integration with the Movement ecosystem. On October 21, 2025, the company announced that sUSDa [staking](https://iq.wiki/wiki/staking) vaults were live on Canopy, a platform described as the \"DeFi gateway\" for the Movement Layer 1 [blockchain](https://iq.wiki/wiki/blockchain). This collaboration introduced several liquidity pools, including single-asset sUSDa staking and sUSDa-USDa liquidity provision, making Bitcoin-backed yield accessible to users on the [Movement network](https://iq.wiki/wiki/movement-network). [\\[5\\]](#cite-id-aYK9MOlRCu)\n\n### Trading Halt\n\nAccording to data from market aggregator [CoinGecko](https://iq.wiki/wiki/coingecko), trading for sUSDa tokens ceased on all listed exchanges at an unspecified date. The 24-hour trading volume was recorded as $0.00, indicating a complete halt in market activity. Prior to this event, the token had reached an all-time high of $1.07 on January 13, 2025, and an all-time low of $0.9844 on January 19, 2025. The cessation of trading marked a significant disruption in the token's lifecycle and liquidity. [\\[1\\]](#cite-id-l0cbfsyGd4)\n\n## Technology and Mechanism\n\nThe functionality of sUSDa is intrinsically linked to its underlying [stablecoin](https://iq.wiki/wiki/stablecoin), USDa, and the broader [Avalon Finance](https://iq.wiki/wiki/avalon-finance) platform. The system combines collateralized debt positions, omnichain technology, and institutional-grade custody to operate.\n\n### sUSDa Generation and Yield\n\nsUSDa is generated when a user deposits the USDa [stablecoin](https://iq.wiki/wiki/stablecoin) into the Avalon Savings Account. In return, the user receives an equivalent amount of sUSDa, which represents their share of the [staking](https://iq.wiki/wiki/staking) pool. The token is designed to automatically accrue value, meaning the holder's sUSDa balance reflects the principal deposit plus the earned yield.\n\nThe yield distributed to sUSDa holders is generated from two primary revenue streams within the Avalon ecosystem:\n\n* **Borrowing Rates:** Interest paid by users who borrow USDa by providing [Bitcoin](https://iq.wiki/wiki/bitcoin) as [collateral](https://iq.wiki/wiki/collateral).\n* **Protocol Revenue:** Fees and other income generated from the broader Avalon lending platform.\n\nThe platform aimed to provide sustainable, double-digit Annual Percentage Rates (APRs). At its launch, Avalon Labs stated that holding sUSDa could generate a yield of approximately 15% APY. The yield mechanism was also designed with an incentive structure to maintain a [staking](https://iq.wiki/wiki/staking) ratio of under 50% of the total USDa supply, suggesting a dynamic adjustment of rewards to manage platform liquidity. [\\[2\\]](#cite-id-VWcF4G190C) [\\[4\\]](#cite-id-Ki3Y3LRh8a)\n\n### Underlying Stablecoin: USDa\n\nUSDa is an omnichain [stablecoin](https://iq.wiki/wiki/stablecoin) pegged to the U.S. dollar, serving as the foundation for sUSDa. It is designed to be fully collateralized by [Bitcoin](https://iq.wiki/wiki/bitcoin) and maintain its peg through several mechanisms.\n\nThere are two primary methods for creating USDa:\n\n1. **Collateralized Debt Position (CDP):** Users can deposit [Bitcoin](https://iq.wiki/wiki/bitcoin) (BTC) as [collateral](https://iq.wiki/wiki/collateral) into Avalon's [CeDeFi](https://iq.wiki/wiki/cedefi-centralized-decentralized-finance) system to mint or borrow USDa. This process comes with a fixed borrow rate, which was set at 8% at launch. The supply of USDa is designed to scale in proportion to the amount of Bitcoin collateral held in custody, a feature intended to mitigate de-pegging risks.\n2. **Direct Conversion:** Users can convert other stablecoins, such as [USDT](https://iq.wiki/wiki/tether), into USDa at a 1:1 ratio through the Avalon vault on the [Ethereum](https://iq.wiki/wiki/ethereum) network. The platform guarantees a 1:1 conversion back to USDT, providing an [arbitrage](https://iq.wiki/wiki/arbitrage) mechanism to help maintain the peg.\n\nThis dual-minting system allows USDa's supply to expand based on both demand for BTC-backed [leverage](https://iq.wiki/wiki/leverage) and direct demand for the [stablecoin](https://iq.wiki/wiki/stablecoin) itself. [\\[2\\]](#cite-id-VWcF4G190C) [\\[4\\]](#cite-id-Ki3Y3LRh8a)\n\n### Omnichain Architecture\n\nBoth USDa and sUSDa were developed using [LayerZero's](https://iq.wiki/wiki/layerzero) Omnichain Fungible Token (OFT) standard. This technical foundation allows the tokens to exist natively across multiple [blockchain](https://iq.wiki/wiki/blockchain) networks without the need for traditional asset bridging, which can introduce security risks and liquidity fragmentation. The OFT standard facilitates seamless cross-chain transfers, enhancing the tokens' utility and accessibility across different DeFi ecosystems. sUSDa has been deployed on several [blockchains](https://iq.wiki/wiki/blockchain), including [Ethereum](https://iq.wiki/wiki/ethereum), [Nibiru](https://iq.wiki/wiki/nibiru-chain) EVM, [Mantle](https://iq.wiki/wiki/mantle-network), [BNB](https://iq.wiki/wiki/binance-smart-chain) Smart Chain, and [Base](https://iq.wiki/wiki/base). [\\[4\\]](#cite-id-Ki3Y3LRh8a) [\\[1\\]](#cite-id-l0cbfsyGd4)\n\n### Security and Collateral Management\n\nTo secure the [Bitcoin](https://iq.wiki/wiki/bitcoin) [collateral](https://iq.wiki/wiki/collateral) backing USDa, Avalon Labs partnered with several institutional-grade digital asset custodians. This approach is central to its [CeDeFi](https://iq.wiki/wiki/cedefi-centralized-decentralized-finance) model, aiming to provide users with confidence in the security of the underlying assets. The custody partners include:\n\n* Cobo;\n* Ceffu;\n* [Coinbase](https://iq.wiki/wiki/coinbase) Prime.\n\nAvalon Labs stated that the custody addresses holding the [collateral](https://iq.wiki/wiki/collateral) are publicly accessible to ensure transparency and allow for independent verification of the reserves backing the USDa [stablecoin](https://iq.wiki/wiki/stablecoin). [\\[2\\]](#cite-id-VWcF4G190C)\n\n## Tokenomics\n\n* **Name:** Avalon sUSDa\n* **Symbol:** sUSDa\n* **Token Type:** ERC-20, [LayerZero](https://iq.wiki/wiki/layerzero) Omnichain Fungible Token (OFT)\n* **Decimals:** 18\n* **Maximum Supply:** Infinite (∞)\n\nThe [tokenomics](https://iq.wiki/wiki/tokenomics) indicate that the circulating and total supply are identical, and there is no hard [cap](https://iq.wiki/wiki/cap) on the maximum supply, allowing it to expand as more USDa is staked. [\\[1\\]](#cite-id-l0cbfsyGd4) [\\[4\\]](#cite-id-Ki3Y3LRh8a)\n\n### Smart Contract Addresses\n\nsUSDa is a multi-chain token with distinct contract addresses on each supported network:\n\n* **Ethereum:** `0x2b66aade1e9c062ff411bd47c44e0ad696d43bd9`\n* **Nibiru EVM:** `0x84f682626302EA7BCA2A7c338b84863292131319`\n* **Mantle:** `0x5a61b1d8272b250729ea3f5ed3ef843f4d66bc6e`\n* **BNB Smart Chain:** `0x73a325103935b0b5e7aa3aca6dba74ad22f82b03`\n* **Base:** `0xd329f9a8589723357c36727a2d5e15974c835ccf`\n\nThese addresses allow users to interact with the sUSDa token on their respective [blockchains](https://iq.wiki/wiki/blockchain). [\\[1\\]](#cite-id-l0cbfsyGd4) [\\[4\\]](#cite-id-Ki3Y3LRh8a)\n\n## Ecosystem and Integrations\n\nThe utility of sUSDa was expanded through several key partnerships and integrations designed to bridge [Bitcoin](https://iq.wiki/wiki/bitcoin)-backed assets into broader [DeFi](https://iq.wiki/wiki/defi) ecosystems.\n\n### DeFi Partnerships\n\nA significant collaboration was established between Avalon Labs, Movement, and Canopy.\n\n* **Avalon Labs:** The core developer of the USDa and sUSDa infrastructure. The project is backed by investors including hiFramework and [Binance](https://iq.wiki/wiki/binance) Labs.\n* **Movement:** A Layer 1 [blockchain](https://iq.wiki/wiki/blockchain) built with the Move programming language, which served as the foundational network for the integration.\n* **Canopy:** A DeFi yield hub on the Movement ecosystem that hosted the sUSDa [staking](https://iq.wiki/wiki/staking) vaults, making them accessible to users on the network.\n\nThis three-way partnership enabled the deployment of several yield-generating vaults on Canopy, including sUSDa single-asset [staking](https://iq.wiki/wiki/staking), a sUSDa-USDa liquidity pool, and a USDa-USDT liquidity pool. [\\[5\\]](#cite-id-aYK9MOlRCu)\n\n### Exchange Availability\n\nOn the Nibiru [blockchain](https://iq.wiki/wiki/blockchain), sUSDa was available for trading on the Oku DEX, a decentralized exchange. It was featured in liquidity pools that allowed users to swap between sUSDa and other [stablecoins](https://iq.wiki/wiki/stablecoin). The primary pools were:\n\n* `USDC / sUSDa`\n* `sUSDa / USDa`\n\nThese pools provided a source of on-chain liquidity for sUSDa within the Nibiru ecosystem.
