CrossPool Overview

A digital platform for private markets! CrossPool enables digital issuance and transactions of assets.

CrossPool is built based on two blockchain systems, the R3 Corda and Hyperledger Indy, composed of the CrossPool core services and multiple instances of the distributed "node" called CrossPool Droplet, a.k.a. XPLet.



Transactions of the Digital Asset-Backed Securities (DABS), a.k.a. asset tokens, take place between the XPLets across the Corda network. Transaction recipient's DID (decentralized identifier or digital ID) will be KYC verified against the Hyperledger Indy network by the CrossPool Indy Oracle service.



XPLet is a free available package consisting of

  • front-end web client
  • back-end server and APIs
  • Hyperledger Indy SDK
  • Corda node
  • MongoDB (optional if you have an existing one of version 4.0+)
  • PostgreSQL (optional if you have an existing one)

Any DABS issuer or service provider could be able to install, customise and run the XPLet to join the CrossPool ecosystem and issue asset tokens with minimal effort.

DABS investors are served by the XPLet and the user data are managed by the XPLet owner (i.e. the issuer) locally. CrossPool processes the transactions only using DIDs and their Indy Verifiable Credentials.


Follow this instruction to setup and run the XPLet dockers.
