The Problem
Accepting crypto payments today is painful
You are overpaying
You fund TRX for every wallet, pay for each transfer, maintain a Vault. For two payments (100 + 16 USDT), it's $16.90 — 14.6% of turnover.
0
real client cost
You are at risk
Private keys for your clients' money are stored on your server. One hack — and you are fully liable. You are effectively an unlicensed bank.
0
loss upon server hack
You are dependent
Custodial processing can freeze your account, delay withdrawals, or shut down. Your turnover is on someone else's wallets.

Real Numbers
Save 4x on a real case
A crypto card service. Two operations: card issuance (100 USDT) + top-up (16 USDT)
Real case: a card service processes two payments — $100 deposit and $16 top-up. On the left — what they pay now. On the right — what they'd pay with VaultFree.
Current setup
Deposit 100 USDT$5.82 gas
Top-up 16 USDT$11.08 gas

Why so expensive?▾
Each payment requires a separate gas deposit to the customer's wallet, a separate transfer transaction, and if the receiving address is new — gas doubles. Two payments cost $16.90 in network fees alone.
Technical detail: you manually send TRX to each HD wallet for gas. Card issuance — sweep to one address, 23.3 TRX. Top-up splits across two wallets (your fee + user's card balance) = 44.3 TRX, because one recipient address was new and gas doubled.

Why cheaper?▾
You pay a flat 5% fee (min $2.00). Gas is included — no extra charges. The smart contract handles everything, so there are no manual costs on your side.
Technical detail: the contract deploys once on the first payment. Subsequent top-ups are a cheap transferFrom ($1.05). No TRX deposits to wallets needed. Your address and platform address are already activated — no double gas. Two transfers (to you + fee) in a single transaction.
At 500 operations per month, the difference is $2,400+. That's money currently burned on gas and infrastructure.
How it works
Four steps — and you're done
For the buyer — a regular transfer. For you — API and webhook.
1
Wallet Creation
Create a unique address for your customer via API. Instantly, for free.
2
USDT Transfer
Buyer sends USDT to the address. A regular transfer from any wallet.
3
Webhook
You get notified instantly: who topped up, how much, and when.
4
Money in your wallet
Smart contract transfers USDT directly to you. Not through us.
01
No keys
No seed phrases, no Vault, no storage. Nothing to hack — nothing to steal.
02
No middlemen
A smart contract instead of a person. Code won't freeze your account or delay withdrawals.
03
No hidden fees
3–5% — and that's it. Gas, monitoring, webhooks included. No network fees, subscriptions, or surprises.
04
No dependency
Your money — in your wallet. If we disappear — you withdraw it yourself via the contract.
Security
No keys — nothing to steal
Even if we are hacked — your funds are safe

Use cases
Build your own crypto service — without holding anyone's money
Crypto cards, gaming platforms, exchanges — anyone can launch a service where users deposit USDT. VaultFree handles the hard part.
Crypto Cards
Your users top up with USDT — you issue cards. Each user gets a permanent wallet address. No invoices, no time limits. User saves the address once and tops up anytime — like a bank account number.
Gaming & iGaming
Players deposit instantly — no checkout pages, no waiting. One address per player, funds on balance in under a minute. Five deposits in one evening? No problem.
Exchanges & Wallets
Launch a crypto service without building wallet infrastructure from scratch. Unique deposit addresses, automatic sweep, webhook notifications — all through one API.
E-commerce & SaaS
Accept USDT for goods, services, and subscriptions. Regular top-ups from repeat customers on the same address. No invoice expiration, no checkout friction.
Any Crypto Business
Every service that accepts USDT deposits builds its own wallet infrastructure — servers, keys, Vault, monitoring. And still overpays on gas and security. We already built it. Connect via API in one day.
You provide the service. We provide the payment rails. Your users' funds go straight to your wallet — never stored on our servers, never at risk of being frozen.

FAQ
Frequently asked questions
Do my clients need to install anything?▾
No. The client makes a regular USDT transfer from any wallet. TronLink, exchange, Trust Wallet — anything.
How fast will I get the money?▾
Enterprise: instantly upon each deposit. Growth: batch sweep once a day. Free: sweep via TronLink (free, you pay gas) or request sweep via platform (5% fee, gas included).
Can I try before I buy?▾
Yes. Free plan — 0% fee forever, up to 5 wallets. Sweep via TronLink for free, or request platform sweep for 5%. Webhooks and monitoring are included for the first 30 days.
Why 3–5% instead of 1% like competitors?▾
Competitors with 1% are custodial: they hold your money and can freeze it. CoinRemitter with '0.23%' actually costs ~1.4% + $100/mo. Our 3–5% is all-inclusive: gas, webhooks, monitoring. Your money is never in our wallets.
What if VaultFree shuts down?▾
You call the emergencySweep function on the smart contract and recover all funds. The contract lives on the blockchain independently of us.
