Product preview with illustrative data. Balances are read from Sui Testnet in the live app.

The problem

Your wallet tracks transactions. It doesn't understand decisions.

Wallets show balances and history. They don't connect what you're about to do with the goals you set, the risks you've reviewed, or the choices you made last month.

So every decision starts from zero: one address, one amount, one confirm button.

With Walguardian

Same transfer, four kinds of context:

  • Protect

    First payment to this recipient. Amount is above this wallet's usual range.

  • Save

    Would take your Gas reserve below the 50 SUI minimum you set.

  • Invest

    SUI would fall outside your target allocation band.

  • Memory

    On Oct 3, 2026 you chose to keep a minimum SUI reserve.

Protect · Save · Invest

One wallet. Three layers of intelligence.

Security, savings and investing usually live in different tools. Walguardian analyzes them together, from the same on-chain data.

01Protect

Understand the risks

Each outgoing transaction is scored against your wallet's own history. Every signal says what was unusual and why, so you can judge it yourself.

Transaction history analysis
A behavioral baseline built from your past Sui activity.
Explainable anomaly signals
Deterministic rules with the evidence behind every score.
Security reviews and feedback
Mark activity as expected or suspicious. Critical signals are never cleared automatically.
Recipient and transaction context
First-time recipients, new packages and outflow size in context.

Anomalies are deviations from your history, not proof of fraud. Analysis is historical, not real-time monitoring.

Give every asset a purpose

Set aside funds for a target or keep a minimum reserve. Walguardian tracks progress against your live balance, not a separate account.

Savings goals
Targets with a date, or reserves you never want to go below.
Earmarked balances
Funds you explicitly assign to a goal, checked against what you hold.
Reserve tracking
See when spending would take a reserve below its minimum.
Progress and contribution planning
Monthly contributions needed and an estimated completion date.

Earmarks are a planning layer. Funds stay in your wallet and are never moved.

See the bigger picture

Compare what you hold with the allocation you want. Values use reference prices you set, so the assumptions are always visible.

Portfolio allocation
SUI, stablecoins and other assets as a share of the whole.
Target strategies
Your target mix and the drift band you are comfortable with.
Allocation drift
How far each asset class has moved from its target.
Illustrative rebalancing scenarios
What it would take to return to target. Never executed.

Testnet assets have no market price. Scenarios are illustrations, not investment advice.

Financial memory

A financial copilot that remembers what matters.

Your decisions shouldn't disappear after every session.

Walguardian keeps the preferences, goals, reviews and decisions you choose to save. It brings back the relevant ones the next time they matter, with their source and date.

Explanation · cites your memory

This transfer would reduce the reserve you previously chose to maintain. M1

Your own preference, saved 2026-10-03. Not verified evidence.

Illustrative example. Dates and amounts are synthetic.

What it remembers

Preferences
Reserves, risk comfort, target allocations and notes in your own words.
Savings goals
Targets, minimums and the funds you earmarked for them.
Security reviews
Activity you marked as expected, suspicious or unsure.
Investment decisions
Scenarios you accepted or rejected, and why.

Every record keeps its source and timestamp. Things you said are kept separate from what the AI inferred, and memories personalize assessments without silencing critical warnings.

Built for Walrus Memory

Walrus Memory is the intended persistence layer: decentralized storage for the context your copilot relies on. Here is where it stands today.

  • Integration

    Built on the official Walrus Memory SDK behind a provider-neutral memory layer.

  • This demo

    Runs on a clearly labelled development mock. The mock is not Walrus.

  • Live persistence

    Pending a reachable Walrus Memory Testnet relayer. Not yet verified end-to-end.

Memories are scoped to your browser session, not to a wallet. Store only non-sensitive information.

Pre-transaction intelligence

Think before you transfer.

Enter a hypothetical transfer and Walguardian evaluates it across all four layers before you go anywhere near a signature.

  1. 01Protect

    Transaction and recipient risk signals from on-chain history.

  2. 02Save

    What happens to your balance, earmarks and reserves.

  3. 03Invest

    How your allocation moves against your targets.

  4. 04Memory

    Relevant notes, reviews and decisions you saved earlier.

Simulation only: nothing was signed or sent. Guardian cannot guarantee that a real transaction would succeed or that a recipient is safe.

An explainable verdict

Deterministic rules set the verdict. Each finding is labelled by how much weight it can bear, so a preference is never presented as evidence. The AI explains the result but never decides it.

AI copilot

Ask better questions about your money.

The copilot sits beside your data, not in place of it. Every claim in an answer cites where it came from, so you can check it before you act.

Your setting

Goals, targets and preferences you configured

Memory

Notes, reviews and decisions you chose to save

The AI explains; it does not verify facts on its own or predict outcomes. Claims without a valid citation are flagged, figures not found in the data are marked, and the copilot falls back to a deterministic summary when the model is unavailable. Nothing it says is financial advice.

How it works

From on-chain activity to informed decisions.

Five steps, each one inspectable. Calculations happen in code; language models only explain them.

Technology

Built on the ecosystem.

Each layer is a separate adapter, so the status of every integration is explicit, including the ones still in progress.

  • Sui
    Blockchain network

    Wallet activity, balances and transactions come from the Sui network. Development and the demo use Sui Testnet.

    Testnet
  • Tatum
    Blockchain data access

    Sui data is read through Tatum's Sui Testnet gRPC gateway and normalized before any analysis runs.

    Live on Testnet
  • Walrus Memory
    Financial memory infrastructure

    The memory layer is integrated with the official Walrus Memory SDK. Live decentralized persistence is not yet verified.

    Demo runs on a labelled mock
  • Gemini
    AI explanations

    Google Gemini writes cited explanations on the server. Without it, the copilot returns deterministic summaries.

    Optional

Walguardian is an independent project. Naming these technologies does not imply a partnership, endorsement or certification.

Security and transparency

Intelligence without surrendering control.

Walguardian helps you decide. It never acts for you, and it tells you what it doesn't know.

  1. 01

    Read-only blockchain analysis

    Walguardian reads public on-chain data. Entering an address is watch-only and does not prove ownership.

  2. 02

    Simulation-only transfer assessments

    Transfer check evaluates hypothetical transfers. It never executes them.

  3. 03

    No signing or broadcasting

    No private keys, no wallet connection and no transactions sent on your behalf.

  4. 04

    Deterministic financial calculations

    Balances, progress, allocation and anomaly scores are computed in code, not by a language model.

  5. 05

    Evidence-backed AI explanations

    Every AI claim cites its source. Unsupported claims and unknown figures are flagged.

  6. 06

    Explicit unknowns and limitations

    Missing data, estimates and assumptions are shown, never filled in.

  7. 07

    Session-based memory isolation

    Memories are scoped to a signed browser session, not shared across users.

Make every financial decision count.

Your wallet already knows what happened. Walguardian helps you understand what comes next.
