What happens when someone pays you
No exchange account, no nodes to run. This is the whole flow.
-
Create a payment
From the dashboard, the API, or an embeddable widget. Price it in USD, EUR, or crypto.
-
Your customer pays
Every payment gets its own fresh address with a QR code, in the customer's language.
-
Nothing counts until the chain says so
Deposits are confirmed on the blockchain and re-verified before anything is credited.
-
The money is yours
The net amount lands in your balance. Withdraw it a minute later if you want.
The annoying parts are handled
Wrong network, wrong amount, paid after expiry. On most processors these are support tickets. Here they are features.
Wrong-network rescue
A customer pays USDT on the wrong chain. It happens more than you would think. Liddie detects it, verifies the deposit on the blockchain, and credits it, usually with no action from you. Allow up to two days.
Short, over, or late
Paid 2% short? Overpaid? Two days late? You set the tolerances once and stop thinking about it.
Balance conversions
Move your balance between any of the 23 coins. The quote you see is locked for 60 seconds.
Getting money out is free
Withdrawals, auto-withdrawals, and mass payouts to 500 recipients carry no Liddie fee. You pay the network cost and that is the end of it.
Widgets without code
Design a payment or donation button, copy one snippet, paste it into your site. That is the integration.
Checkout in 7 languages
Your customers pay in English, Spanish, French, German, Italian, Portuguese, or Finnish.
23 currencies. 13 networks. One integration.
From Bitcoin to Solana, plus USDT on six networks and USDC on four. XRP credits in seconds; Bitcoin takes about half an hour.
Pricing that fits in one sentence
One flat fee when a payment succeeds. Nothing monthly, nothing to set up, no minimum volume.
What you never pay
- Monthly or setup fees
- Chargeback fees: completed crypto payments are final
- Fees on withdrawals or payouts, network cost only
- A markup on network fees: they pass through untouched
Security that fails closed
When something cannot be verified, nobody gets credited. We would rather be slow than wrong.
- Passkeys and mandatory two-factor authentication
- Withdrawals only to addresses you whitelist, confirmed with MFA
- A unique deposit address for every payment, never reused
- On-chain verification before any balance credit
- Everything sensitive is encrypted at rest
- The books are checked against the blockchain around the clock
Integrate it this afternoon
One POST creates a payment. A signed webhook tells you when the money is real. Same envelope on every response.
And if you never want to touch the API, payment links and widgets do the same job without a line of code.

}Questions merchants actually ask
What does it cost?
One flat fee per successful payment, nothing else from us. The exact rate lives on the pricing page.
When is the money mine?
Once the network has confirmed the payment enough times and it passes on-chain verification, the net amount is credited to your balance and can be withdrawn immediately.
What if a customer sends the wrong coin or the wrong amount?
Wrong-network deposits are detected and credited once the deposit can be verified on the blockchain, which can take up to two days. Underpayments and overpayments follow tolerance rules you configure, and late payments are recovered for up to two days after expiry.
Do you hold my funds?
Yes, Liddie is custodial: payments are credited to your Liddie balance. You stay in control: withdrawals go exclusively to addresses you whitelist, and auto-withdrawal rules can keep your balance near zero.
Which coins can I accept?
23 currencies across 13 networks: BTC, ETH, SOL, XRP, TRX, BNB, LTC, DOGE, DASH, BCH, MATIC, AVAX, plus USDT on 6 networks and USDC on 4.
Do I need to write code?
No. Create payment links from the dashboard or paste an embeddable payment or donation button into your site. The API is there when you want it.
What does signing up take?
An email, a password, and two-factor authentication. Restricted business categories go through an onboarding review before accepting payments.
How do I turn crypto into stable value?
Accept stablecoins directly (USDT on 6 networks, USDC on 4) or convert your balance between coins in seconds with quotes locked for 60 seconds. Liddie is crypto-in, crypto-out: there is no bank settlement.

Signing up is free and takes minutes. You pay one flat fee when you get paid, and nothing when you do not.
