Certificate of Incorporation
A legal document and license relating to the formation of a company or corporation, and is also regarded as the birth certificate of the company.

Business Registration
A legal document of registration with local authorities, establishing the business as a legal entity. For example, if your company is formed in BVI and operates in Hong Kong, please provide the Certificate of Incorporation from BVI and Business Registration from Hong Kong.

Company shareholder structure chart (also regarded as: ownership structure chart) refers to who owns how many proportions of different types of shares per company. The shareholder structure is the foundation of the corporate governance structure.
The company shareholder structure chart needs to be traced back to the ultimate beneficial owners (UBO), who could be one or more natural persons. We need passports or identity document of shareholders and UBO who hold at least 10% of the shares.
Sample:

Memorandum of Association is a legal statement that contains all the fundamental information which are required for the incorporation of the company. Articles of association are written rules about running the company agreed by the shareholders or guarantors, directors and the company secretary for company governance, purpose, operations, etc.
ERC20 is one of the most commonly used token standards on the Ethereum blockchain, used for creating and issuing interoperable tokens. It defines a set of specifications and interfaces that enable token contracts to interact seamlessly on the Ethereum network. The majority of mainstream cryptocurrencies can be traded and transferred using ERC20. However, due to Ethereum's rich architecture and ecosystem, the network often suffers from congestion and insufficient capacity. Since Ethereum network usage is priced based on transactions rather than the additional cost of Ether (ETH), users incur extremely high network fees when using ERC20 tokens.
When you need to transfer assets to iSunOne, we sincerely recommend using the TRC20 network.
TRC20 is a token standard on the Tron blockchain, similar to ERC20, used for creating and issuing interoperable tokens. TRC20 defines a set of specifications and interfaces that enable token contracts to interact seamlessly on the Tron network.
Compared to Ethereum, the Tron network offers faster transaction confirmation speeds and lower transaction fees. When transferring assets using the TRC20 network, users can enjoy faster transaction confirmations and avoid high network costs. iSunOne sincerely recommends using the TRC20 network to transfer assets, in order to achieve a faster and more cost-effective transaction experience. We are committed to providing users with convenient, secure, and cost-efficient asset management services, and choosing the TRC20 network is an ideal choice to fulfill this goal.
TXID (transaction hash) is also called blockchain hash, is a unique string of characters given to every transaction that's verified and added to the blockchain. TXID is an identification number that labels each transaction on the blockchain. With TXID, you can check your top up and send on-chain history with blockchain explorer.
For TRC20 assets such as USDT-TRC20, USDC-TRC20, the blockchain explorer is:

For ERC20 assets such as ETH,USDT-ERC20, USDC-ERC20, the blockchain explorer is:

For BTC, he blockchain explorer is:

On the Swap page, select source and target asset, enter the amount, and click submit.

In the Digital Account, please click Withdrawal.

Input withdrawal amount, then address that you are withdrawing to. You can also save an address by clicking "Add address".

Be sure to fill in the correct asset, network, and address.

Please input the email verification code and PAY code to proceed.

At turbulent times, the digital assets are safer hibernating in a cold wallet, rather than staying in a centralized exchange (essentially a database) or decentralized exchange (smart contracts can have wormholes). If you have not ordered a Ledger or Trezor yet, and happen to have 1 or 2 used iPhones, please read carefully for one of the best hidden secrets in cryptocurrency.
The simple version:
A. Make sure your used iPhone has never been jailbroken. Reset to factory origin status.
B. Download any non–custodial wallet (such as coinbase wallet, trust wallet, imtoken, exodus) app. Non-custodial means you, not the exchange or platform, controls the private key. Write down or remember 12 or 24 word “seed phrases” in private.
C. Withdraw bitcoin from exchange to the address of your cold wallet.
D. Remove SIM card, keep your phone in airplane mode, go off grid, stay off line. Turn off the phone (now a cold wallet) and let it sleep in a private physical vault.
The advanced version:
With certain types of non-custodial wallet apps (such as tokenpocket), you can set up an “observer wallet” as a companion to the “cold wallet”. Essentially, the observer wallet serves as a blockchain explorer to the cold wallet. The observer wallet stays online for monitoring, while the cold wallet stays offline to keep the private key safe. When it comes to the time to withdraw the funds, you need both the observer wallet and the cold wallet to create signatures and broadcasting.

The SWIFT system is a complex established cash flow and information flow system. iSunOne seamlessly connects to the SWIFT system, has multiple partners, and is familiar with the rules of the SWIFT system.

The U.S. government governs the SWIFT system and provides a pivotal guidance forregions, such as: Hong Kong, Singapore, Switzerland, Dubai, etc.

Circle is applying to become a US licensed and federally chartered national commercial institution. We will send wire transfer using the most befitting business partner.
iSunOne and its business partners are always ready to provide you with remote assistance. Even if the borders are closed due to the global epidemic, your assets can still flow through borders, through digital dollar USDC, to a Hong Kong account. Depending on your circumstances, our partners may offer remote witness account opening. In addition to introducing customers to overseas accounts, iSunOne is also responsible for the most important item: whitelisting.
During the process of external account opening, it is required to perform at least two types of compliance operations for each individual or business user:
1. Know Your Customer (KYC), that is, the knowledge of the user, including the ultimate beneficial owner of the company or legal entity;
2. Anti-Money Laundering (AML), that is, for the source of each fund, the receiving institution has the right to detect its legality and compliance.
The whitelist service of iSunOne is to ensure that every fund remitted from Circle Internet Financial LLC, the digital dollar issuer, will reach the overseas account of VIP customers compliantly through the iSunOne path after introducing overseas account opening. It is equivalent to iSunOne helping to place the user's account on the whitelist. If necessary, it can also help to provide necessary data to pass compliance review. This can greatly reduce the probability of any accounts being closed.
Hence, we recommend using the digital dollar U on the blockchain to carry out international trade and payments. Asset transfer between two iSunOne accounts is free and instant.

When you purchase from an international online merchant, you may notice an additional fee called an "ISA fee" on your transaction statement. ISA stands for "International Service Assessment," which is a fee charged by Visa to cover the costs associated with processing transactions across borders. This fee is typically a small percentage of the total transaction amount, and it varies depending on the country where the merchant is located. When purchased with iSunOne Global Visa Card, an ISA fee would be charged around 1% of the current single transaction amount. To deal with this fee, you can try to find out if the merchant has a local presence or if they accept payment through a local payment service.
For more details about ISA Fee, please read the article below:
