Thirdfy is a control layer for AI finance agents, with user-defined rules, approval prompts and signed action records. Its safeguards add oversight, but do not remove the risks of trading through connected protocols.

Our verdict on Thirdfy

6.5/10

Thirdfy may suit users who want AI agents to research and prepare finance actions without giving them unchecked signing authority. Its clearest strength is the combination of user-set limits, venue checks and an approval step before a wallet signs. MCP support also lets users connect agents that run outside the app. The main caveat is that these controls do not remove the risks of connected protocols or trading, and the listed audits lack published detail here. Check fees and audit reports before relying on the service.

What is Thirdfy?

Thirdfy is a finance-agent platform that lets users coordinate AI agents and connect them to supported protocols. It presents itself as a control layer rather than simply a decentralized exchange: agents propose actions, while user-set rules and approval prompts govern execution.

The project describes rule checks for mandates, allowlists, limits and venue readiness. A wallet signs an action only after the user approves its order card, and Thirdfy says actions—including refused ones—are recorded. Its Agent Index displays signed agent records and ranks agents by reported 30-day profit and loss.

Thirdfy runs on Base and names TFY as its token. It lists two audits, but does not detail their scope or findings. Detailed fees and the token's role are also not published in the project information described here.

How Thirdfy works

Thirdfy acts as an intermediary between finance agents and connected protocols. Users can work with agents in its Command app or connect their own through MCP. Agents can research and propose actions such as swaps, lending transactions or trades on supported venues; Thirdfy describes support for Base swaps and integrations with venues including Hyperliquid and Polymarket.

5 features

Key features

Multi-agent Command

Users can coordinate multiple agents in a shared Command room and direct an individual agent with an @mention.

MCP connection

Thirdfy offers an MCP connection for agents running outside its app, so they can reach supported protocols through a common interface.

Rule-based checks

Proposed actions are checked against rules such as mandates, allowlists, limits and venue readiness before they are sent for approval.

Approval before signing

Thirdfy says a wallet signs an action only after the user approves its order card, with the rules checked again before signing.

Signed Agent Index

The Agent Index records approved and refused actions and presents signed agent scores, including 30-day profit and loss rankings.

Pros and cons

What we like

Offers approval prompts rather than signing proposed actions automatically.
Lets users set limits and restrict which venues agents can access.
Supports both its Command interface and external agents connected through MCP.
Records agent actions, including refusals, and offers signed track records through the Agent Index.

Watch out for

Thirdfy does not publish detailed fee information.
The listed audits are not accompanied by their scope, findings or dates.
User-defined rules and approval prompts can reduce execution risk but cannot eliminate smart-contract, venue or market risk.
The service depends on the supported protocols and venues being available and ready.
The Agent Index's signed performance records do not guarantee future results.

Thirdfy fees

Thirdfy does not publish detailed fees. Check its Pricing section for current charges. Fees from connected protocols or networks may also apply, and their costs depend on the action and venue.

Is Thirdfy safe?

Thirdfy says it lists two audits, but their scope, findings and dates are not detailed here. The project describes rule checks and user approval before wallet signing; these controls do not guarantee that an action is safe, correctly interpreted or profitable. Smart-contract vulnerabilities, compromised agents or wallets, and failures at connected venues remain possible.

The project does not publish a regulatory status in the information described here. Users should review audit reports and understand how their wallet interacts with each protocol before approving transactions.

6 steps

How to get started with Thirdfy

1
Open Thirdfy Command or prepare an agent that can connect through its MCP interface.
2
Connect the agent and choose the supported protocols or venues it should be able to use.
3
Set the agent's mandates, allowlists and limits before allowing it to propose transactions.
4
Ask the agent to research or prepare an action, then review its order card and rule-check results.
5
Approve only actions you understand; Thirdfy says the wallet signs after approval and checks the rules again.
6
Review the signed action record or the Agent Index to inspect recorded activity.

Who Thirdfy is for

Thirdfy is aimed at crypto users who want to use AI agents for research or transaction preparation while retaining approval over execution. It may also suit developers connecting their own agents through MCP. It is less suitable for people who want a simple exchange interface or who are not comfortable reviewing proposed transactions and managing wallet and protocol risks.
