Crypto Settings

Crypto Settings are the various BUY and/or SELL configurations for your operation:

• the types of trades your BATM terminals will allow (and how),

• the interfaces and parameters between CAS, wallets, and exchanges,

• the retail prices displayed & offered.

Open

You may set various configurations depending upon your organization’s preferences. This permits you to granularly fine-tune your terminals, or apply broader rules if you should so choose.

Open	+ADD: creates a new Crypto Setting.
	Displays current balances for all Hot Wallets.
	Click to edit the configuration, or click on the setting “Name”.
	View the Terminals that use that individual Crypto Setting.
	Duplicate to use the existing configuration as a template. Click to copy, then use a new name and adjust it as needed.
	If you have more than one Crypto Setting, you will have the option of deleting one. The setting must be unused to delete it.

COMMON SETTINGS:

The first few fields are the same no matter what type of Crypto Setting you’ve created.

Name*: Add a description of the type of purchase/sale. Specify the crypto type and exchange, with a markup% to help identify it, i.e. “Coinbase BTC 10% Buys”

Crypto Currency*: identify the type of crypto being used – selecting one will open a customization window for further refining the supported transactions.

Organization*: typically the default, sole organization already setup, used to help segregate settings. You can setup multiple organizations if you host a CAS for other companies.

• The fields here may vary by crypto type.

Currency Unit: Select the standard unit of measurement for exchange rate to be displayed.

Allowed Discount Codes: check if you wish to allow discount codes for this type of trade.

Configuration Cash Currency*: select the standard currency that you wish to set as the default.

BUY SETTINGS:

Minimum Cash Amount Per Transaction*: the smallest fiat amount you'll trade at this set rate.

1. set this to the smallest possible trade you can manage.

2. The first bill inserted into the acceptor must be at least this size. Additional banknotes can be smaller (as determined by your Fiat Settings).

3. ALWAYS exceed any Exchange minimum transaction amount! (normally ~ $20 USD)

Don't generate vanity addresses for paper wallets: this privacy measure reduces the exposure footprint to your customers.

Minimum Card Amount Per Transaction*: the smallest credit/debit amount you'll trade at this set rate.

Buy Rate Source: select one of the supported wallets/exchanges for quoted rates (only).

• Your Buy Rate Source should match your Exchange provider when possible.

• Some rate sources are limited in frequency (“rate limited”). If you experience frequent rate failures, try a different provider, and understand that for each coin the source is listed, it will request a rate.

  • e.g. three coins = 3x the rate

Parameters (Buy Rate Source): (typically optional) enter any fiat currency for rates (e.g. USD, EUR) if the default (blank) doesn’t produce expected results.

Rate Fetching Period: determines the frequency of rate requests from your BATM to CAS. Some rate providers limit the number they’ll provide in a given time, and you don’t want to exhaust that. You also want a responsive price - so this setting allows you to adjust the rate calls to your needs.

Stabilize Buy Rate Source: Stabilizes the rate source using a moving average.

• Stabilizes the rate source using a moving average. When the buy rate moves down, the stabilized rate will slowly follow but when the rate goes up the stabilized rate will go up immediately. This way the stabilized rate source is always equal or more favorable for the ATM operator compared to the non-stabilized source.

Hot Wallet Buy: this is one of two possible sources of crypto for a BUY. You may also use an Exchange in addition to (or in place of) a hot wallet depending upon your needs & desires.

• Documented Hot Wallets: Hot Wallets

• “no forward” wallets are relevant in SELL transactions. See: https://generalbytes.atlassian.net/l/cp/QVg60Nyt

Parameters (Hot Wallet Buy): (required) enter the wallet parameters here.

• Documented Hot Wallets: Hot Wallets

• The format of the parameters varies by provider.

Wallet Tunnel Enabled: only offered for nodes, this option secures access to node servers.

• Find instructions here: Install the GB Wallet Tunnel Server

• Enter the tunnel password (after installation) in the Wallet Tunnel Password parameter.

Output Queue: enables batch submission of BUY transactions.

• This option may reduce your mining fees & increase security.

• See: CAS: Output Queues

Secondary Output Queue: Secondary output queues can only be used with custom server extensions (otherwise the selected secondary output queue is not used).

The Secondary Queue enables you to specify which transactions go into the [main] Output Queue - and which transactions will go into the Secondary Queue.

Example:
Let’s say that you enable a donation screen where all small donations will queue until $1000 USD is reached - and then the $1000 queue is flushed.

• Without the Secondary Queue, the [main] Output Queue would flush donations too often - generating high mining fees, and making those low-priority transactions too expensive.

Transaction unlock delay: the delay (in minutes) before a transaction is broadcast. The default is 0 (no locking). Locked transactions will display with a lock icon in the transaction log and output queue list. This setting is useful to address government-forced refund periods (e.g. Connecticut, USA).

Exchange Buy: this is one of two possible sources of crypto for a BUY. You may also use a Hot Wallet in addition to (or in place of) a hot wallet depending upon your needs & desires.
