Mantis

Mantis is an intent-based trading application on Solana that lets users express a desired outcome—swap USDT on Ethereum for a Solana token, for example—and then delegates execution to a decentralized network of solvers that compete to fulfill the trade at the best price, with automatic gas handling and built-in MEV protection. The project launched its mainnet beta in December 2024 and is built by the ComposableFi team.

The Intent Model

Traditional decentralized exchanges require users to navigate liquidity pools manually, choose routes, approve gas tokens on each chain, and accept whatever price the automated market maker offers. Mantis replaces that workflow with an intent layer: users declare what they want, not how to get it. A decentralized solver network—composed of specialized algorithms competing in real time—evaluates available paths across Solana, Ethereum, and connected chains and submits the route that best satisfies the user's conditions.

Solvers earn fees by winning this competition, which creates economic pressure toward better pricing rather than toward extracting value from users. MEV—the practice of reordering or sandwiching transactions for profit at a user's expense—is structurally discouraged because solvers operate in a secured settlement environment where user intents are batched and committed before execution paths are revealed.

Cross-Chain Infrastructure

Cross-chain execution is powered by Picasso's IBC Hub, which extends the Inter-Blockchain Communication protocol beyond the Cosmos ecosystem to Solana, Ethereum, and Polkadot. Mantis leverages this infrastructure to route trades without requiring users to manually bridge assets or hold native gas tokens on each chain—the protocol handles gas conversion and bridging internally. This makes swapping between Solana-native tokens and Ethereum-based assets a single-step interaction from the user's perspective.

The Mantis on-chain program on Solana Mainnet is deployed at AhfoGVmS19tvkEG2hBuZJ1D6qYEjyFmXZ1qPoFD6H4Mj and is classified in Solana program taxonomies as an L2 product.

AI Trading Interface

Mantis distinguishes itself within Solana's DeFi landscape by pairing its solver infrastructure with a proprietary AI layer called DISE. The DISE LLM was trained specifically on the Mantis SDK to interpret natural language trading commands and convert them into structured intents the solver network can process. This powers a Type & Trade interface in which a user can type a plain-language instruction—such as "swap 500 USDC for SOL when the price drops below $140"—and the agent handles execution without further input.

Three tiers of AI capability are part of the product roadmap:

• Personalized Agents: Live at launch. Agents tailored to individual user preferences, drawing on DISE and market signals curated through a feature called Lady Mantis insights.
• Agents with Conditionality: In development. These support conditional order logic—automated strategies that trigger based on price levels, time conditions, or portfolio thresholds.
• Vault Strategies: Planned for a future phase. Collaborative, evolving yield strategies powered by specialized agents and accessible to all users on the platform.

M Token

Mantis has an SPL token, $M, with a total supply of 100 million tokens. The token is designed to support the Mantis ecosystem and its governance and incentive mechanisms, and to advance the protocol's decentralization over time. $M is listed on multiple exchanges and tracked on CoinGecko.

Team and Backers

Mantis was built by ComposableFi, the team behind Composable Finance and the Picasso Network. ComposableFi's core focus has been cross-chain infrastructure—expanding IBC connectivity to non-Cosmos chains—and Mantis is the consumer-facing trading application sitting atop that infrastructure stack. Omar Zaki, a principal at ComposableFi, presented Mantis at Solana Breakpoint 2024, framing the project as the realization of the team's cross-chain infrastructure work in a product accessible to everyday DeFi users.

In December 2024, Arthur Hayes, founder of BitMEX and CIO of Maelstrom, agreed to serve as a strategic advisor alongside Maelstrom. Hayes highlighted the cross-chain gas abstraction as a practical differentiator, describing the ability to move from USDT on Ethereum directly into Solana tokens—with gas handled automatically—as a meaningful improvement over existing cross-chain trading workflows. Maelstrom's involvement brings institutional DeFi trading expertise to the project at an early stage.

Positioning on Solana

Mantis occupies a niche that is growing in importance on Solana: the execution layer for AI agents. As autonomous on-chain agents become more prevalent, they require a trading substrate that can interpret flexible instructions, route across chains, and execute without human-in-the-loop approval of each step. Mantis is designed to serve both human users who want simplified DeFi access and AI agents that need a programmable, intent-compatible execution environment.

The project launched its mainnet beta in December 2024 and competes with other intent-centric protocols, but is differentiated by the combination of Picasso's IBC cross-chain infrastructure, the DISE LLM, and strategic backing from figures with deep roots in derivatives and high-frequency trading markets.
