What is USDP?

USDP Token is the token of the Paxos platform built on Ethereum blockchain technology (ERC-20 protocol) in 2018. USDP Token is fully backed 1:1 USD issued by the Paxos Trust Company and is approved and regulated by the NYS Department of Financial Services. PAX is also known as USD Digital.

Like other stablecoins such as USDT, PAX aims to combine the stability and reliability of the US dollar with the benefits of digital money. Namely, to make it so that it can be transmitted via the Internet to anyone on the planet, instantly, at any time and practically without commissions.

PAX smart contract

Do not submit PAX through a third party contract. Our exchanger does not accept transactions that are sent by third party smart contracts, except for the original PAX contract.

Network fee

To work with tokens, the wallet must have ETH. It is very difficult to calculate the exact amount of ETH to send a transaction. During periods of high load, it can change significantly. Each token can have a different transaction value. Therefore, it is better that the amount of ETH on the wallet is slightly higher than the average fee on the network at the moment. The average commission can be estimated using the Blockchair analytical service.

The system does not see the transaction, what should I do?

If you have sent funds, but there are no changes, check your transaction in an explorer (etherscan.io or blockchair.com) and make sure that the transaction was created.

If the transaction has already been added to the blockchain, and the system has not seen it, contact technical support, we will be able to help you promptly.

A brief history of the Lightning Network

The Bitcoin community has long been baffled by the scalability issue. The speed of transactions fell, and the network fees grew. In 2015 Thaddeus Dria and Joseph Poon proposed a solution called the Lightning Network. The idea was to carry out some of the transactions outside the network, thereby reducing the load on the BTC blockchain. In 2018, the Lightning Network was launched in Bitcoin.

The Lightning Network is a system that helps users move funds among themselves without having to use a blockchain to verify a transaction. Instead, there is a quick check of funds from the sender and a request from the recipient who agrees to the transaction.

Problems you may encounter while getting the Lightning Network

1. If during the creation of an order when inserting an invoice, an error occurs about the absence of a path, this means that there is no created channel between our node and your wallet node. A channel is required to send and receive payments on the Lightning Network. If there is no open channel between our node and your wallet node, the payment will not be executed. It is recommended to try using a different wallet.
2. If the order page indicates that the order was completed, but you did not receive the funds, then the reason for this may be:

• Disconnected intermediate node. If one of the intermediate nodes is offline, the transaction may be delayed.
• Insufficient amount of deposits on intermediate channels. Intermediate nodes cannot forward the payment due to lack of coins.
• The invoice is out of date. Each invoice has a validity period. Of this term has expired, the payment will not work.

If your order is completed, but you have not received the funds, please contact technical support. We can help you quickly.

Lightning Network Speed

Since transactions on the Lightning Network do not end up on the blockchain, they are almost instantaneous. But if one of the intermediate nodes is off the network, the transaction may be delayed.
