I am looking for Multiple Cryptocurrency Custody services with API access, where I can generate payment addresses and receive payment notifications (IPN), and the API also has the option of sending payments.

I found BitGo, but there are only 7 coins in the Pay As You Go plan. I also found NowPayments that would be perfect for my purpose, however they are a Non-Custodial service, so it is not feasible for my project.

In short, what I need are service recommendations that have the following characteristics.

. Multiple currency options (the more the better), mainly: BTC, ETH, LTC, DOGE, TRX
. API for generating payment addresses and sending payments
. IPN for notifications of payments received
. Custody of balances, because the balance needs to stay in the account until I decide to withdraw it or make payments when necessary

My goal is to create a micro-wallet system for small value transactions avoiding fees from the Blockchain network. I know that the best option would be to host the wallets on my own server so as not to depend on third party services, but for the time being this option is not viable because the initial cost will be high.


Sites that do exactly what I want to do in my project: Faucetpay, Expresscrypto


Anyone who has suggestions for services that have these characteristics, comment here.


Best regards
