4th March Update

Progress is continuing at a good pace.


The current version of the Fusion Multi-Ledger Rollup has running since before Christmas. Key features implemented and tested recently are as follows:

  • Token withdrawals via the optimism route: tested for all token types, i.e. QNT, unified tokens, single chain tokens.
  • "Instant" Token withdrawals via the Secure Asset Exchange Protocol (SAEP)*: tested for all token types.
  • Deposit UI: Accessible via Quant Connect & Metamask. Swap UI and Withdrawal UI are currently being worked on.
  • Lots of infrastructure hardening for the mainnet production environment

*progress has been made for SAEP to become an official working group item within the Internet Engineering Task Force (IETF) Secure Asset Transfer Protocol (SATP) Working Group. We await final confirmation on this.


For the Fusion Network of Networks we expanded on the "Bring Your own Node" functionality so that users can now "Bring Your own Network". Currently this is enabled for public testnets of the DLT types:

  • Aptos
  • Cosmos
  • Ethereum Virtual Machine
  • Hedera
  • Solana
  • SUI

Expanding to other DLTs and expanding to private or permissioned networks is now just an incremental change away.

Additionally we implemented the architecture for "Bring your own App" (BYO-app), which allows internal or external developers to code a service against a specification and then have it be displayed & useable inside Quant Connect, as well as consumable for AI Agents at the same time. BYO-app is currently being internally tested before release.

Next Steps

We are making key decisions regarding:

  1. When to add load to most of the new fusion networks
  2. The final configuration of the staking feature (to be trialed on testnet first)
  3. The final configuration of the Fusion Rollup mainnet
  4. The priority order of Fusion Network of Network releases (BYO-app, private/permissioned networks, other DLTs,...)
