EchoCart only spends what you have already funded.

How it works
A controlled shopping loop, designed for real spending.
EchoCart acts like a calm concierge. It searches, scores, explains, and only buys within the balance and rules you already set.
01
Fund your EchoCart balance
Add USDC to your EchoCart balance. EchoCart uses it to pay merchants on your behalf — your details stay private.
02
Set clear spending rules
Define order caps, daily and weekly limits, plus an auto-buy threshold for smaller purchases.
03
Describe what you want
Say what you want, your budget, and any preferences. EchoCart searches the web and ranks the best options.
04
Approve or auto-buy
EchoCart buys automatically when the deal is within your rules, or asks before bigger purchases.
Why EchoCart is different
It judges the deal, not just the product.
EchoCart compares price advantage, ratings, merchant quality, delivery speed, discount signals, and your own spending preferences to decide what is genuinely worth buying.

Product preview
A simple app surface behind the intelligence.
The UI stays deliberately minimal so the recommendation quality and financial control model stay front and center.
Assistant
Natural shopping requests
Describe what you want and get ranked recommendations with clear reasons to trust the result.
Wallet
Balance visibility
Track available funds, top-ups, and deductions without leaving the flow.
Controls
Spend with guardrails
Per-order caps, daily and weekly limits, plus auto-buy only when it makes sense.
Private by default
Merchant privacy built in
Merchants see EchoCart's card, not yours. Your wallet address is never shared.
Trust and controls
Safe enough to automate.
- Max spend per order keeps one request from turning into an oversized checkout.
- Daily and weekly limits keep EchoCart aligned with your actual budget.
- Auto-buy only happens below the threshold you define.
- Larger orders pause for confirmation before any deduction happens.
Search experience
Use it like a shopping assistant.
