"Saving it in the spankbank" wasn't a double entendre before Spankchain.![camgirl1-600x370.jpg](https://steemitimages.com/DQmNqKvaCvKZVXuQfhRWogfot7V3vvVhi1vRXvd5AqBFHox/camgirl1-600x370.jpg)
*But to the company, SpankBank is just one  part of a technology stack that makes cheap, quick and easy micropayments to performers possible.

*It starts, though, with the company's spankwallet , an in-browser wallet that connects to an ethereum payment channel. This wallet allows users to load ether into a payment channel with SpankChain and use that value to tip performers.

*Ethereum's fee mechanism, gas, is only charged when users open a new payment channel or exit a payment channel, otherwise users can make as many transactions as they want without a fee from there.

*In building this, SpankChain seems ahead of ethereum developers more broadly who have been working on building useful payment channel technology for the blockchain for some time.

*The spankcoin token then is used for staking to the SpankBank, and it then regularly emits another token called "booty."
