What Goes Into a Modular Onchain Agent? (1)
While many AI agents rely on APIs, interfaces, and orchestration layers, EarnKit was designed to power fully autonomous, onchain actors. This article explores the core components of EarnKit’s agent architecture—from memory and modular capability sets to smart wallet infrastructure and transaction routing—and explains why modularity is the foundation for scalable, programmable agent ecosystems.
What Goes Into a Modular Onchain Agent?
A Deep Dive into EarnKit’s Architecture
The next generation of crypto infrastructure won’t be built for users—it will be built for agents. These agents aren’t interfaces. They’re systems: autonomous actors capable of observing the world, making decisions, and executing transactions across protocols.
At EarnKit, we’re not building agent UIs or wrappers. We’re building the system underneath them.
This is what we call the modular agent architecture—and it’s designed from the ground up for execution.
Why Modularity Matters
Web3 moves fast. Protocols change, strategies evolve, tooling shifts. A tightly coupled agent that can’t adapt to new inputs or extend its abilities is a dead end.
EarnKit agents are designed to be modular—meaning their functions can be composed, updated, and reused without rewriting the whole system. Think "agent as a strategy stack," not "agent as a product."
This modularity powers flexibility, safety, and scale.
The Four Core Layers of an EarnKit Agent
Every EarnKit agent has four architectural layers:
- Smart Wallet Execution Layer
The agent’s “body”—responsible for signing and submitting transactions. Built with security and modular control in mind, this wallet system enables gas logic, capability scoping, and transaction routing.
- Modular Capability Layer
Capabilities are isolated, reusable functions that the agent can call (e.g., swap, vote, bridge, rebalance). They are permissioned, version-controlled, and context-aware.
- Semantic Memory Layer
Agents learn from past interactions. EarnKit’s memory system enables agents to persist state, track performance, and adapt strategies based on prior behavior.
- Intent Orchestration Layer
This is where reasoning happens—transforming user input, time-based triggers, or data signals into executable onchain actions using the agent’s available capabilities.
Together, these layers form the full execution stack.
Why This Approach Works
EarnKit agents aren’t one-off automations. They’re reusable primitives that can be:
- Forked and remixed
- Observed and audited
- Deployed across verticals
- Upgraded without downtime
This is how we scale: not by building monolithic bots, but by enabling thousands of programmable agents that evolve over time.
A Platform for Builders
Whether you’re running a fund, designing governance workflows, or deploying DeFi strategies—EarnKit provides the composable infrastructure to do it autonomously, with execution guarantees and observability built in.
Agents aren’t apps.
They’re systems.
And modular systems are the only ones that scale.
