Gateway Node
The gateway node is an integral part of the Arcana Auth blockchain protocol.
It facilitates blockchain transactions and contract interactions for the Web3 apps that register with Arcana through the Arcana Developer Dashboard and integrate with the Arcana Auth SDK.
The gateway node manages app configuration for using the Arcana Auth SDK and forwards blockchain requests from Web3 apps to the Arcana Auth blockchain protocol. After a user authenticates and approves a transaction, the gateway node parses and sends it to the Arcana blockchain as a meta-transaction. A meta transaction includes the actual initial transaction.
It uses meta transactions to support 'gasless transactions' whereby app users don't have to pay transaction fees and the gateway node handles payment management via bundlers and gas tanks.
