Odyssey is building a DeFi hub built on ERC-4337 smart contract accounts. Odyssey offers gasless, cross-chain execution and smart contract wallets for programmable account behavior.
Loopr, Bundlr, and Yieldr are DeFi modules on Odyssey that automate leveraged yield strategies. Each position is isolated in a smart contract, preventing risk spillover across strategies.
Odyssey has integrated Aave, Compound, Morpho, and Ajna, and plans to integrate LayerZerofor seamless multichain strategy execution. Odyssey’s supported chains include Ethereum, Base, and Optimism, with support for Hemi coming soon.
Upcoming modules include Tradr (portfolio management), and Odyssey AI (strategy engine), as well as expanding automation and mobile support.
Primer
Odyssey is a DeFi application for cross-chain portfolio management and leveraged yield strategies that supports several top DeFi protocols on Ethereum, Optimism, and Base. Odyssey is built on ERC-4337 infrastructure, which shifts account logic to smart contract accounts, enabling programmable and customizable account behavior. This infrastructure powers gasless transactions, letting users interact with multiple protocols and chains even if they don’t hold native gas tokens.
The platform's architecture includes two key interfaces: Loopr and Bundlr. Loopr automates leveraged yield strategies via looping (depositing collateral, borrowing against it, and redepositing the borrowed assets), eliminating manual looping execution. Bundlr batches multi-step DeFi actions like deposits and swaps into a single transaction.
Metronome, Odyssey's primary integration, issues synthetic assets backed by user-deposited collateral. These synthetics function as dynamic debt instruments, useful for looping and leveraged strategies. As of Q2 2025, Odyssey is in public beta.
DeFi is hindered by structural and UX challenges that make it difficult for users to monitor, understand, and manage their assets across multiple platforms. Some of these problems include:
Deep fragmentation: Protocols operate in isolation, forcing users to switch between products and hindering a cohesive view of their positions.
User-level complexity: Each protocol has unique mechanics that require time and technical understanding to use effectively.
Inconsistent UX: The lack of interface standards creates steep learning curves and can frustrate users performing basic tasks.
Odyssey simplifies the DeFi experience, allowing users to swap, loop, access yield, and manage their position in a single application.
Odyssey’s Architecture
In March 2023, Ethereum deployedERC-4337, enabling smart contract accounts (SCAs). Unlike externally owned accounts (EOAs)—wallets controlled by a single private key (i.e., MetaMask or Phantom)— SCAs are programmable accounts that can batch transactions, abstract gas fees, and manage execution logic onchain through smart contracts.
Odyssey supports two core ERC-4337 features: UserOps, a programmable transaction format for batching and automation, and EntryPoint, a standardized, trustless coordinator that processes these operations. Together, they enable SCAs to perform more complex actions than EOAs, which are limited to basic transactions. Example SCA use cases on Odyssey include:
An SCA on Odyssey could automate a yield farming strategy by periodically harvesting profits, reinvesting them, and adjusting leverage, all within a single UserOp processed by the EntryPoint, without repeated user input.
With interfaces like Loopr or Bundlr (two DeFi integrations on Odyssey), users can batch actions such as borrowing from Aave, swapping on a DEX, and depositing into Metronome into one UserOp, reducing transaction steps for the user.
SCAs on Odyssey can operate without holding ETH and use a paymaster (e.g., funded by the platform or a partner) to cover gas fees. EntryPoint manages the fee process, enabling seamless execution of complex strategies.
Odyssey uses ERC-4337 to simplify multi-step DeFi workflows through a unified smart contract account interface. By introducing account abstraction through gasless fees, batched transactions, and automation, Odyssey users can create and manage multi-step strategies across multiple protocols and chains on a single account-based system.
The Odyssey team previously built Metronome, a synthetic asset protocol used in Loopr. In April 2025, Zane Huffman (AKA Jeff Green on X), a DeFi trader known for strategy research, transitioned from leading strategy to CEO. Odyssey is in public beta with an alpha launch planned sometime soon. Future development will prioritize new protocol integrations, improved transaction routing, and user feedback implementation.
Integrations
Odyssey adds conditional logic to protocols like Aave and Metronome through smart contract accounts, enabling composable strategies that are more capital efficient and convenient for users. Each position is isolated in its own smart contract to reduce systemic risk and prevent cross-position interference. This design also lets users manage multiple strategies in parallel from a single interface.
Metronome integrates with Odyssey through its synthetic asset engine, allowing users to mint synthetics against crypto collateral. This lets users retain exposure while unlocking liquidity for additional yield.
Vesper Finance, a core yield source in Odyssey, provides pools for earning passive returns. Within the Loopr module, Vesper serves as the initial deposit point, accepting various collateral types, including naked assets like ETH, WETH, and vaETH pool tokens, before capital is routed through Metronome. This is separate from the FlashLoanExecutor contract, which implements the ERC-7579 module interface to perform flash loans on behalf of SCAs.
Vesper Finance, a core yield source in Odyssey, provides pools for earning passive returns. Within the Loopr module, Vesper is the initial deposit point before capital is routed through Metronome, which employs flash loan leverage and synthetic leverage strategies. These strategies enhance user flexibility, offering greater freedom and access to a wider range of blue-chip assets for leveraging yield.
Other integrations include:
Aave: A widely used lending protocol for overcollateralized borrowing with variable interest rates. Aave’s flash loan feature enables uncollateralized borrowing, which is repaid within a single transaction.
Compound: An interest-rate protocol for earning and borrowing assets with an algorithmic interest rate. Odyssey has integrated Compound, like Aave, as a base layer for lending operations within automated workflows.
Morpho: A peer-to-peer lending protocol that matches borrowers and lenders directly atop Aave and Compound. Odyssey routes through Morpho to optimize lending and borrowing rates when matches are available.
Ajna: A permissionless lending market with no governance or price oracles that instead relies on time-weighted average pricing and bucket-based liquidity. Odyssey abstracts Ajna’s unique mechanics to offer standard borrow/repay flows and leverage strategies.
Odyssey supports Ethereum, Optimism, Base, and soon, Hemi—an EVM-compatible L2 interoperable with Bitcoin. This multichain approach allows users to select the optimal network for their specific strategies/needs, such as speed or cost. Odyssey plans to incorporateLayerZero, a cross-chain messaging platform, enabling seamless asset management across blockchains through a single interface.
New Product Features
Loopr: Automated Collateral Looping
Loopr automates borrowing, swapping, and redepositing to compound exposure. It integrates Metronome to generate synthetic assets that track underlying collateral (e.g., converting USDC into msUSD), enabling yield compounding through a single transaction.
Because Odyssey isolates each Loopr position within a user's smart contract account, users can manage isolated strategies with different risk profiles in one account. Loopr’s performance fees (taken from user profits) scale based on protocol usage. Users who combine Metronome and Vesper pay 2%; using either individually costs 6%, while non-integrated strategies incur a 10% fee.
On May 25, Odyssey announced a UI update that lets users loop strategies across all supported chains on one dashboard.
Bundlr: Multi-Step Execution
Bundlr allows users to bundle multiple DeFi actions, like send, swap, deposit, and borrow, into a single atomic transaction (i.e., all actions in a transaction either fully succeed or fail together). This reduces gas costs and prevents partial execution.. Users can edit, reorder, and preview sequences before signing.
Bundlr currently supports transfers, token swaps, and bridging. Future updates will add conditional logic and support for composable operations. On May 25, Odyssey announced a UI update for users to access Bundlr from anywhere in the application.
Yieldr: Curated DeFi Vaults
Yieldr is Odyssey’s yield aggregation module, designed to simplify access to DeFi vaults across multiple protocols and chains. It standardizes yield discovery and deployment through a unified interface, allowing users to earn yield without navigating multiple platforms.
Yieldr integrates with ERC-4626-compliant vaults for uniform interactions and share-based accounting. When a user deposits assets like USDC, their SCA executes the transaction, receives vault shares, and accrues yield over time.
Yieldr supports 4,600 vaults from protocols such as Vesper, Yearn, Morpho, and other vault providers.
Gas Sponsorship and ERC-20 Payments
During its beta, Odyssey will subsidize gas for up to 10 daily L2 transactions, or up to $1 in gas costs per user, whichever comes first. L1 transactions still require ETH. Future support for ERC-20 gas payments will let users pay fees in USDC or other tokens, reducing friction for newcomers who don’t hold ETH.
Roadmap
Odyssey’s four-phase roadmap centers on expanded functionality, usability, and capital efficiency. No launch dates have been made public for these roadmap items.
Phase 1: Launch of Loopr and Bundlr, plus leaderboard and points system.
Phase 2: Bundlr 2.0 and EIP-7702 integration for enhanced account abstraction.
Phase 3: Tradr (portfolio management suite) and support for conditional transactions through Fillers.
Phase 4: Odyssey AI (strategy engine) and mobile application with full feature access
Closing Summary
In April 2025, Odyssey introduced its core infrastructure for a modular DeFi platform built around smart contract accounts. Using ERC-4337, the protocol enables users to perform DeFi actions, such as swapping, borrowing, and looping collateral, without holding ETH or signing every transaction. The announcement of two key tools, Loopr and Bundlr, adds functionality to improve the UX for DeFi. Loopr automates leveraged yield strategies using synthetic assets, while Bundlr allows users to bundle multiple DeFi steps into a single transaction. These features reduce approvals and combine portfolio management across networks.
Odyssey also integrated DeFi protocols Metronome, Vesper, Aave, and Morpho, adding yield generation, synthetic asset minting, and peer-to-peer lending to the protocol’s unified interface. Depending on desired strategies, cost, and latency requirements, users can choose between Ethereum, Optimism, and Base. The roadmap outlines upcoming features like Tradr (a trading interface) and an AI strategy engine designed to simplify complex workflows without sacrificing control.
As a unified DeFi execution layer tackling the ecosystem’s key usability and structural challenges, Odyssey has the potential to onboard new users of all experience levels, growing the DeFi market towards its TAM of the entire global financial services market.
