A funding protocol determines the method by which a card is provided with available balance. How a cardholder can deposit or withdraw, and how the Immersve platform can settle or refund.
Cards can be funded by a variety of protocols. These variants and their use cases are described in the following sections.
On-Chain Funding
Whether your app is custodial or non-custodial you can pre-fund cardholder spend with deposits on-chain.
Non-custodial On-Chain Funding
Users pre-fund card spend by making deposits to your instance of the Protocol.
Custodial On-Chain Funding
Your app funds card spend by making deposits to your instance of the Protocol.
Flexi Variant
An on-chain funding protocol variant that is designed to be optimized for decentralization. Each individual cardholder has their own funding address. Cardholder balance can be inspected on-chain and permission-less withdrawal is supported. See Algorand Funding Protocol for more information.
Universal Variant
An on-chain funding protocol variant that is designed to be optimized for gas fees. It can be used by both custodial and non-custodial users. Individual cardholder balances are pooled together and recorded off-chain. See Universal EVM Funding Protocol for more information.
Funding Simulator
A test funding protocol which can be used for experimenting with Immersve APIs without configuring on-chain components. See Simulator Funding Protocol.
Funding Types
A Funding Type is the combination of a protocol, network and token. It determines the behavior of any Funding Source related to a particular partner Funding Channel.
The table below shows the supported Funding Types on the Immersve Platform.
