About#
Vortex provides on and off ramps betwen FIAT and crypto in a decentralized manner, by the use of smart contract protocols, a special purpose DEX designed specifically for FIAT and several cross-chain protocols.How it works#
In a nutshell, Vortex provides a comprehensive transaction handling which works cross-chain and cross-protocol to deliver the funds from the starting chain and token into the corresponding payment processors, that provides the redeem to FIAT.
The same is true for the onramp counterpart, where the flow is reversed.All the bridging and swap operations happen in a decentralized and trustless manner. This is achieved by traditional smart contract logic as well as a set of pre-signed transactions from special-purpose accounts (ephemeral accounts), that live only for the purpose of a specific transaction, and are in full control of the client since the keys are generated right before any ramp, and by the client itself.These transactions that must be pre-signed are defined by the Vortex backend and once signed, are delivered back to Vortex were they are sent in the correct sequence ensuring the flow of funds moves seamlessly.This architecture ensures that Vortex does NOT control funds and any point along the ramp flow until it reaches the FIAT payment processors, and should the backend not fulfill the proper handling, the client can complete the ramp manually.
At the core of the architecture we find a special purpose DEX running on Pendulum chain, which is used to get the best crypto-to-forex prices for the main swap.Modified at 2025-05-21 15:54:26
