Metraxia

Stock-aware infrastructure for autonomous portfolio management.
Tokenized stocks on Base. Owner-defined mandates. Enforced execution rules.

[Metraxia @MetraxiaHQ]

Metraxia's first policy engine is working.

Today, I completed the initial engine and ran it through 43 automated tests. All 43 passed.

The demo also verified a chain of 20 decision receipts across normal trading and adversarial scenarios.

A few things it handled: 👇

[Vantarix @VantarixHQ]

One agent. Three interfaces. The same wallet.

An onchain agent might initiate a transaction through an MCP server, a trading platform or a custom-built application.

The security of that wallet shouldn't depend on which interface the agent happens to use.

As the founder of Metraxia, I want to make this absolutely clear: we have not launched a token.

Bankr has acknowledged that the deployment was unauthorized and that the token has no official affiliation with Metraxia.

[Metraxia @MetraxiaHQ]

Allowed trading to resume when the relevant conditions were satisfied.

The agent can adjust and resubmit a proposal, but the deterministic engine makes the final decision.

All executions in this demo are simulated.

43 tests passed. 20 receipts verified.

[Metraxia @MetraxiaHQ]

- Blocked trades exceeding a 20% position cap.
- Held trades during corporate action windows.
- Blocked stale-price trades.
- Enforced trading halts through an owner-controlled kill switch.
- Rejected an agent's attempt to lift the halt without the owner's signature.

@bankrbot @ShoutoutStock This deployment was requested by an account impersonating @MetraxiaHQ.

Metraxia has not launched or authorized $SOUT. The account copied our branding, original posts and mascot Xia to create a false association with our company.

[Metraxia @MetraxiaHQ]

@ShoutoutStock @bankrbot To be absolutely clear:

Metraxia has NOT launched a token. $SOUT is NOT affiliated with us.

We are building autonomous portfolio infrastructure for tokenized stocks on @base.

Please report and block @ShoutoutStock. Help us protect the community from this impersonation.

[Metraxia @MetraxiaHQ]

SCAM ALERT ⚠️

An account operating as @ShoutoutStock is impersonating @MetraxiaHQ, copying our bio, original posts and mascot Xia.

The account has used this stolen identity to request a token deployment through @bankrbot, resulting in the deployment of $SOUT.

Meet Xia 👀 The mascot for @MetraxiaHQ.

While my workspace was down, I designed 29+ screens for Metraxia from scratch on my phone. Now, I'm writing the Policy engine while I wait for the repair.

[Metraxia @MetraxiaHQ]

@base The beginning

[Metraxia @MetraxiaHQ]

@base This is our starting point.

[Metraxia @MetraxiaHQ]

We are building for the emerging market of autonomous stock finance.

As tokenized equities become part of onchain markets, portfolio management will require infrastructure designed around the specific characteristics of assets

Metraxia is developing that infrastructure on @base

On Metraxia you can manage tokenized stock portfolios through autonomous agents.
Set investment mandates that define how your agent can operate.
Enforce stock-aware trading rules before transactions are executed. And much more

I'm building Metraxia for the Agentic Stock Finance track.

@MetraxiaHQ is focused on making autonomous portfolio management safer through stock-aware execution controls and owner-defined trading mandates.
