Wallet Addresses Management
Payid19Wp needs wallet addresses to receive payments. You can add the addresses manually (recommended) or you can use the addresses created just for you from Payid19 servers automatically by obtaining them via Payid19Wp Plugin (Payid19 servers do not give the addresses given to you to others and do not save them).
There are three different address types in Payid19Wp:
| Payment receiving addresses: | These are the addresses shown to users to receive payments. |
|---|---|
| Feeder Addresses: | These are the addresses used to transfer the fee required for the transfer of tokens. Feeder addresses can also be used as main wallets. |
| Main address: | These are the main addresses where the tokens arriving at the payment receiving addresses are collected. |
Getting Addresses
You can enter your wallet addresses manually. After entering the Addresses section via the plugin, you can add your addresses manually via the opened modal by clicking the Add Addresses Manually button. Depending on the density of your site, adding an average of 20-30 addresses for each network and coin will be enough to start.
If you do not want to enter the addresses manually, Payid19Wp automatically takes 20 addresses from the Payid19 servers for the coin selected on the Checkout page and saves them in your database.
You can also enter the main wallet and feeder addresses manually.Feeder addresses and Main Wallet addresses are found in the Main Wallets tab.
Feeder addresses are used to transfer the fee required for the transfer of tokens.
Main wallet addresses are the addresses where all incoming payments are collected.
You can also use feeder addresses as main wallet addresses.
If you do not want to enter the Feeder and main wallet addresses manually, Payid19Wp automatically takes from the Payid19 servers when you click "Get Main Address From Payid19 Servers" button.
Collecting Payments
Payid19Wp can collect your payments in your main wallet address thanks to the Flow service, which can be enabled/disabled via Dashboard.
When using the Flow feature, the private key of the payment address and the feeder address are sent to Payid19 servers(addresses and private keys are not recorded by Payid19 servers.)
Stable coins such as USD Tether, USDC, BUSD and TUSD require some fee (gas, energy, etc.) for transfer, You need to keep some Coins in the feeder addresses.
Ether is required to transfer tokens using the ERC20 network, BNB is required to transfer tokens using the BEP20 network, and TRX is required to transfer tokens using the TRC20 token.
Payid19Wp takes enough fees from your feeder addresses and transfers them to the payment receiving addresses on your behalf.
You can managing Main Wallet address, Feeder address and collect payments manually and using applications such as Metamask, Tronlink, Bluewallet, TrustWallet without using the Flow feature.
What is Margin Ratio?
Since users who want to receive payments with cryptocurrency usually transfer money from exchanges, they may sometimes send incomplete payments.
By using the Margin Ratio feature, you can accept payments that are incomplete enough to not cause you losses, and your customers will have a better experience.
Example:
If you enter USDT TRC20 1 in the Margin Ratio section when you want to receive a payment of 100 dollars, the order will be processed as Completed even if the payment is 99 dollars.Another Example:
You want to receive a payment of 100 dollars and you set BTC 0.0001 in the Margin Ratio section. After 100 dollars is converted to BTC, even if 0.0001 BTC is missing, it is considered successful and the order is recorded as 'Complated'.
Request Extra Fee
You can charge your customer more for the coins you want.
Example:
If you write 5 in the Request extra fee for USDT section, 105 USDT will be requested from your client for a $100 deposit.
