Who it's for
Different segments, one infrastructure: exchange, wallets, liquidity and AML are already assembled and work together.
Building an engine, wallets and exchange integrations is slow and expensive — and hot wallets get hacked.
Every network is a separate integration: addresses, incoming tracking, gas for tokens.
You need swaps inside your product, not a dedicated team for them.
How a deal works
No sign-up for the user: a pair, an amount and a payout address — and they get a unique deposit address. From there the system runs the deal on its own.
The payout address and memo/tag are validated. A unique deposit address is issued with a 3-hour waiting window.
The block scanner catches the deposit and waits for confirmations. Sender and payout addresses are checked against the blacklist and AMLBot.
Disputed deal → operatorThe deal follows the pair's route: KuCoin, HTX or Changelly. Same coin on a different network — the swap is skipped.
Floating rateThe signer verifies the transaction and limits and sends funds to the user's address. A payout never goes out twice.

Features
Three stages, each through its own provider. Cross-chain transfers of the same coin between networks.
For each pair you set where to accept the deposit, where to swap and where to pay out from. “Any coin → X” templates.
KuCoin and HTX order books over WebSocket, Changelly every 20 s. ≈2,000 directions are recalculated every second, with a fallback calculation on failure.
Blacklist and AMLBot for sender and recipient. Disputed deals go to manual review; manual address checks from the admin panel.
Deals with statuses and logs, treasury across all exchanges and wallets, pairs, networks, routes, blacklist.
A fee is set on every deal and split between you and the partner who brought the client. The share is calculated in USDT.
Security
Not “the most secure” — specific mechanisms. Each one closes a real attack scenario against a hot wallet.
It re-parses it and refuses if it doesn't match the operation: an extra recipient, a foreign token contract, an inflated fee.
Per transaction and per 24 hours for each asset. Optionally — a whitelist of recipient addresses.
Every payment is idempotent — even if the process crashes mid-send.
The signer signs nothing until the operator unseals it.
The log entry is written before the signature is issued. Withdrawals and refusals are sent to Telegram.
Key storage — Argon2id + XChaCha20-Poly1305. One BIP39 phrase restores all 9 networks.
Networks & assets
No middleman: deposit addresses, incoming tracking and payouts go through your signer. No nodes of your own needed: public or paid RPCs with failover.

With Cloud we run a dedicated server for you; with self-hosted everything runs on your servers and only you hold the keys. The core and features are the same.
Only successfully completed deals, in USDT equivalent at the rate at the time of the deal. Failed, refunded and expired deals don't count.
Exchange and network fees, AML checks at AMLBot rates, paid RPCs and servers for self-hosted. You pay these directly to the providers.
No. The core works through public or paid RPCs with automatic failover.
Swap routes go through KuCoin, HTX and Changelly. You register the accounts in your name and put the API keys into your instance — funds on the exchanges belong to you.
Sender and recipient addresses are checked against the blacklist and through AMLBot. Disputed deals go to the operator for a manual decision, and addresses can be checked manually from the admin panel.
