Connext provides non-custodial layer 2 payment-channel technology that enables off-chain, instant payments with low (or zero) transaction costs, helping scale the Ethereum network and paving the way for use cases like micropayments. Focusing on user experience and adoption, Connext launched its own implementation - the Dai Card - in March 2019. The Dai Card hosts an Ethereum wallet in the user’s web browser. Users can load the card with Dai (or ETH, which will automatically be swapped for Dai). Once funded, the Dai Card can be used to send instant payments to any other Dai Card holder (or non-holder via a link that sets up a Dai Card and let the recipient redeem the payment). The Dai Card currently recommends $30 maximum deposit, and the sole payment hub is currently operated and collateralized by the Connext team.
Connext launched its V1.0 and the Dai Card to showcase payment channel capabilities and gather user info to improve future iterations in development. [Connext V2.0, https://medium.com/connext/connext-v2-0-is-on-mainnet-b818864d3687] and [Dai Card on V2.0, https://medium.com/connext/dai-card-on-connext-v2-0-eed923c52de2] launched in Sept 2019 and Oct 2019 respectively. v2.0 runs on Counterfactual’s framework for general state channels. Connext has no native token and currently charges no fee.
