The New Direction: Agent Execution—and Its Real Cost

The current working direction for defi.io is straightforward to describe:

Let AI agents execute DeFi strategies within rules controlled by the user.

The user stays on defi.io, configures an agent, grants limited authority, and watches every action in real time. The agent can interact with protocols such as Uniswap or Aave without asking for a wallet signature for every routine step.

This is technically possible. It is not a normal web feature.

One signature must not mean unlimited authority

A user can authorize future actions through a smart account and a session key. The key can be restricted by time, assets, protocols, action types, amounts, and spending limits. It must be revocable, and the user’s primary wallet must remain in control.

A plain signature that hands broad authority to a backend agent is not acceptable. Neither is storing the user’s private key on defi.io.

The agent must not hold the signer directly

The planning model should propose actions, not possess unrestricted signing power. A separate policy and execution service must validate every proposed transaction against deterministic rules before a narrowly scoped signer can authorize it.

The safe path is closer to:

user policy
-> agent proposal
-> protocol and parameter validation
-> transaction simulation
-> limit checks
-> scoped signature
-> broadcast
-> monitoring and audit log

An allowlist of protocol addresses is not enough. A permitted Uniswap router can still receive a malicious token, extreme slippage, or an attacker-controlled recipient. Controls must inspect function calls, parameters, assets, destinations, price impact, and expected state changes.

The first version must be narrow

A credible MVP should support one chain, a small set of audited protocols, and a few repetitive actions. For example: swap approved assets within a daily cap, supply or withdraw from one lending market, and rebalance under explicit thresholds.

It should use small balances, conservative defaults, emergency revocation, transaction simulation, rate limits, and real-time user-visible logs. “Supports all DeFi” would be a security failure disguised as product ambition.

From website cost to infrastructure cost

This direction requires smart-account integration, session-key policies, contract registries, protocol adapters, simulation, secure signer operations, monitoring, incident response, and independent security review. The work moves from application-level engineering toward wallet and transaction infrastructure.

That means higher cost, slower protocol expansion, and a much higher standard of operational reliability. A polished interface cannot compensate for weak key management or incomplete policy enforcement.

Demand is still unproven

The stronger user value does not remove the need for validation. The decisive question is behavioral:

Will users put real funds into a smart account, approve a limited session key, and continue allowing an agent to execute without manual prompting?

Interviews can test trust boundaries. A prototype can test setup friction. Only a small real-money pilot can test continued delegation.

The current thesis is not “autonomous finance will win.” It is narrower: recurring DeFi actions may be delegated when authority is explicit, constrained, revocable, and visible. Whether that value justifies infrastructure-level cost is the question for the next phase.
