Payment gateway for BANANO

accept-banano is a server program that helps you to accept BANANO payments in a fast, secure and cost-efficient way.

You can use it independently or together with it's web client accept-banano-client.

There are several options:

• Download the latest binary from releases page
• Pull Docker image: docker pull tigwyk/acceptbanano
• Compile from source: go get -u github.com/tigwyk/accept-banano

• You need a running BANANO node (version >= 21) for communicating with BANANO network.
  • If you are going to setup your own, see instructions
    • "rpc_enable" and "enable_control" options must be enabled in node config
  • If you don't want to setup your own, you can use a node proxy. There are several options. Some of them are:
    • https://mynano.ninja/api/node
    • https://api.nanos.cc/
• Create a config file for accept-banano. See Config section below.
• Run command: accept-banano -config /path/to/the/config.toml

You can create a Docker container for accept-banano that works perfectly with your Docker Nano Node. The configuration and database are stored at /opt/data so you should map that folder to your host.

docker run -d -p 8080:8080 -v ~/accept-banano:/opt/data tigwyk/acceptbanano

Example configuration with BANANO node:

version: '3'
services:
  accept-banano:
    image: "tigwyk/acceptbanano"
    restart: "unless-stopped"
    ports:
     - "8080:8080"
    volumes:
     - "~/accept-banano:/opt/data"
  node:
    image: "bananocoin/banano"
    restart: "unless-stopped"
    ports:
     - "7071:7071/udp"
     - "7071:7071"
     - ":::7072:7072"
     - ":::7072:7074"
    volumes:
     - "~:/root"

• accept-banano is a HTTP server with 2 primary endpoints.
  • /api/pay for creating a payment request.
  • /api/verify for checking the status of a payment.
• From client, you create a payment request by posting the currency and amount.
• When accept-banano receives a payment request, it creates a random unique address for the payment and saves it in its database, then returns a unique token to the client.
• After the payment is created, accept-nano starts monitoring the destination account for incoming funds. It does this by sending a request to node and listening blocks from network via Websocket connection.
• While accept-banano is checking the payment, the client also checks by calling the verification endpoint. It does this continuously until the payment is verified.
• The customer has a limited amount of time to transfer the funds to the destination account. This duration can be set in accept-banano config.
• Then the customer pays the requested amount.
• If accept-banano sees a pending block at destination account, it sends a notification to the merchant and changes the status of the payment to "verified".
• At this point, the payment is received and the merchant is notified. The client can continue its flow.
• The server accepts pending blocks at the destination account.
• The server sends the funds in destination account to the merchants account defined in the config file.

• Config is written in TOML or YAML format.
• The structure of config file is defined in config.go. See comments for field descriptions.
• All of the configuration options can be overriden with ACCEPTBANANO_ prefixed environment variables. This makes configuring the Docker container easier.

• accept-banano does not need to know your merchant wallet seed. It takes payments from customers and sends them to your merchant account address defined in config file.
• accept-banano server is designed to be open to the Internet but you can run it in your internal network and control requests to it if you want to be extra safe.
• accept-banano does not keep funds itself and passes incoming payments to the merchant account immediately. So there is only a short period of time when the funds are held by accept-banano.
• Private keys are not saved in the database and derived from the seed defined in the config. So you are safe even if the database file is stolen.
• Key generation and block signing is done in accept-nano process. That means private keys does not leave the process in any circumstances.

• Please open an issue if you have a question or suggestion.
