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.
Universal Variant
A protocol designed for gas optimisation, that can be deployed on any EVM chain. It can be used by both custodial and non-custodial users. Individual cardholder balances are recorded off-chain. See Universal EVM Funding Protocol for more information.
Flexi Variant
A flexible protocol that supports individual Funds Storage Contracts per cardholder, supporting on-chain balances and permission-less, decentralized withdrawal.
Webhook Funding
Funding via webhook. Authorization requests are forwarded and decisioned by your app.
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.
