A solver is defined as an entity that executes a specific task requested by a user, known as an "intent."

What Is a Solver?

A solver is defined as an entity that executes a specific task requested by a user, known as an "intent." These solvers compete against each other to fulfill the user’s intent in the most efficient way possible, typically prioritizing speed, minimizing cost, or both. In return, the solver receives compensation—often in the form of alpha (i.e., economic incentives or surplus) set aside by the user as part of their intent.
Some of the most impactful solvers in the crypto space today are human participants or market makers. In the future, solvers will likely take the form of AI agents. The broad definition of Solver allows for a diversity of approaches and methodologies, enabling solvers to operate effectively in various contexts and markets.

Take, for example, a user who creates an intent to swap Ethereum for Bitcoin if a specific price ratio is met. This intent is broadcast to an open market where solvers bid for the right to execute it. The winning solver executes the task—purchasing bitcoin if and when the condition is met. This mechanism ensures that tasks are handled efficiently, transparently, and competitively.

The Role of Solvers in the Crypto Ecosystem

Solvers play a critical role in the crypto ecosystem by acting as the operational backbone for certain DeFi and other blockchain-based applications. They function as intermediaries who ensure that user intents are executed seamlessly, adding a layer of efficiency and competitiveness to the system.
At their core, solvers enable the automation and optimization of complex tasks within the crypto ecosystem. This includes activities like trading, arbitrage, liquidity provision, collateral rebalancing, and automated yield farming. By bidding to execute intents, solvers introduce market-driven efficiency, ensuring that users receive the best possible outcomes for their requests.

Moreover, solvers serve as a bridge between intent creation and execution. This makes them vital for the practical realization of web3 principles, such as decentralization, transparency, and user sovereignty. By decentralizing task execution, solvers reduce reliance on centralized intermediaries, enabling a more robust and trustless ecosystem.

Types of Solvers

In the crypto space, solvers can take various forms, each with unique capabilities and roles:

  1. AI Agents: These are algorithmically driven solvers that leverage machine learning and artificial intelligence to execute tasks with precision. They are particularly effective in tasks requiring data analysis, predictive modeling, or rapid execution.

  2. Market Makers: Traditional market makers act as solvers by providing liquidity and facilitating trades within a given market. They ensure price stability and reduce slippage for users.
  3. Human Participants: Not all solvers rely on automation. Skilled traders, developers, or other individuals can act as solvers, especially in niche markets or for complex intents requiring human judgment.

  4. Hybrid Solvers: These combine AI-driven algorithms with human oversight to achieve optimal results. Hybrid solvers are particularly effective in situations where human intuition and machine efficiency must work in tandem.

How Solvers Are Changing DeFi?

Solvers are fundamentally reshaping the DeFi landscape by introducing unparalleled efficiency, accessibility, and automation. Here are a few key ways they are transforming DeFi:

1. Optimized Liquidity Management

Liquidity is the lifeblood of DeFi, and solvers play a pivotal role in its management. By dynamically bidding for intents related to liquidity provision, solvers ensure that capital is deployed in the most effective manner. For instance, solvers can optimize liquidity pools by rebalancing assets to maximize yield or minimize impermanent loss, making DeFi platforms more attractive to users and investors.

2. Cost Efficiency

In traditional finance, intermediaries often add layers of cost and inefficiency. Solvers eliminate these inefficiencies by competing to execute intents at the lowest possible cost. This competition benefits users, as they receive better pricing for transactions, lower gas fees, and higher net returns.

3. Increased Automation

Automation is a cornerstone of DeFi’s value proposition, and solvers take it to the next level. By automating complex processes like yield farming, collateral management, and trading strategies, solvers reduce the need for manual intervention. This not only saves time but also minimizes the risk of human error.

4. Market Efficiency

The competitive nature of solver bidding drives market efficiency. Solvers continuously analyze market conditions, executing tasks in a way that optimizes outcomes for users. For example, arbitrage-focused solvers can identify and capitalize on price discrepancies across exchanges, ensuring price parity and reducing inefficiencies.

5. Enhanced Accessibility

By simplifying complex processes, solvers make DeFi more accessible to a broader audience. Users no longer need to possess deep technical knowledge or spend hours managing their investments. Instead, they can rely on solvers to execute tasks on their behalf, democratizing access to advanced financial tools.

Challenges and Considerations

While solvers offer significant advantages, they are not without challenges. Key considerations include:

  • Security: As solvers gain access to user intents and associated funds, robust security measures are essential to prevent exploitation.

  • Fairness: Ensuring that solver markets operate transparently and equitably is critical to maintaining user trust.

  • Scalability: As the crypto ecosystem grows, solver networks must scale to handle increased demand without compromising efficiency.

  • Regulation: The evolving regulatory landscape may impact how solvers operate, particularly in jurisdictions with stringent compliance requirements.


About Author: Axal

Axal is a network for verifiable autonomous agents. Any action of importance in web3 requires users to discover, specify, and maintain a series of transactions across a fragmented modular stack, a process that wastes resources and limits development possibilities. Axal outsources generalized intents to competitive solver auctions. From complex DeFi strategies to security procedures, users need only state their intent while Axal finds optimal solutions. Axal’s first product, Autopilot, is an agent-powered trading platform that automates yield generation, asset rebalancing, and cash outs catered to specific risk profiles. Founded by a Harvard computer scientist and backed by CMT Digital, a16z Crypto Startup School, Escape Velocity and other top investors, Axal is already working with prominent web3 organizations like Movement Labs and Gitcoin to automate core systems.
