Spectrum Finance
Spectrum is a pioneering open-source, cross-chain DEX reference on the eUTXO model. The team published a formal sunset notice and froze Ergo contracts in February 2024, so this page treats Spectrum as historical infrastructure rather than an active venue for new swaps or liquidity.
Historical Features
- Liquidity Provision & Yield Farming: Historical AMM and LP design reference; not recommended for new deposits.
- Babel Fees: Demonstrated token-paid fee flows where liquidity and miner inclusion existed.
- Cross-Chain Support: Historical Cardano (ADA) and Ergo (ERG) eUTXO DEX work.
- Open-Source: Pioneering codebase that remains useful as an eUTXO DeFi study reference.
Spectrum Bloom
Next-generation eUTxO-native framework for decentralized finance (DeFi), designed to address and improve upon the limitations of early decentralized exchanges (DEXes).
eUTxO Model
Utilizes the eUTxO blockchain model, as seen in Ergo and Cardano, supporting multi-stage contracts and multi-token functionality with enhanced security and transparency.

Spectrum Bloom: Next-Generation DeFi Framework
Spectrum Bloom is an upcoming eUTxO-native framework for decentralized finance (DeFi), designed to address and improve upon the limitations of early decentralized exchanges (DEXes).
Highlights from the Spectrum Bloom White Paper
- Addressing Early DEX Limitations: Spectrum Bloom aims to overcome issues such as lack of transparency, composability, and poor performance in early DEX implementations.
- Decentralization and Openness: The framework focuses on principles of decentralization, openness, transparency, and sustainability.
- eUTxO Model: Utilizes the eUTxO blockchain model, as seen in Ergo and Cardano, supporting multi-stage contracts and multi-token functionality.
- Innovative DEX Protocol: Includes a novel protocol for DEX that consists of both on-chain (UTxO and validators) and off-chain (event handlers for state transitions) elements.
- Liquidity Pooling and Execution: Spectrum Bloom proposes unique approaches to liquidity pooling and order execution, aiming to streamline processes and reduce overhead.
- Universal Order Composition: Introduces universally composable orders, which can be fulfilled from any liquidity source, enhancing flexibility and efficiency.
- Autonomous Account (AA): A key feature where an on-chain entity can validate execution and release user funds for trading, facilitating a dynamic set of applications on eUTxO blockchains.
- Future Extensions and Applications: The white paper also discusses potential extensions and applications of the Autonomous Account concept beyond DEXes.

In a Nutshell
Spectrum Finance remains important as a historical eUTXO DEX reference. For live trading or liquidity, verify current venues, contract status, liquidity depth, and official links before using funds.
