Connected Networks

The Quant Fusion Multi-Ledger Rollup (MLR) connects multiple public and permissioned blockchains into a unified execution environment. This section lists the networks currently supported in the test environment and their roles in the rollup.

Public Test Networks

Network	Description	Example Tokens	Key Smart Contract	Purpose
Ethereum Sepolia	Ethereum testnet for public development and cross-chain testing.	QNT Token and USD Token	Deposit Contract	When QNT is deposited to the rollup, it becomes the native token of the rollup, powering gas and execution fees within MLR. Additionally deposits/withdrawals of ERC-20 tokens are enabled to demonstrates the rollup’s cross chain asset model.
Polygon Amoy	Polygon testnet providing high-throughput, EVM-compatible testing.	GBP Token	Deposit Contract	Deposits/withdrawals of ERC-20 tokens are enabled to demonstrates the rollup’s cross chain asset model.

Permissioned Network

Network	Description	Example Token	Key Smart Contract	Purpose
Quant Besu Private Network	Ethereum-compatible private network operated by Quant, designed for enterprise and regulated use.	EURO Token	DepositPortal	Showcases how permissioned blockchains and tokens can be connected to the rollup, allowing them to be merged into one execution environment with public tokens

Future Networks

The rollup is ledger-agnostic, allowing additional networks to be connected over time, including:

Other public Layer 1 blockchains.
Permissioned enterprise DLTs
Regulated private networks requiring compliance-grade interoperability.

⚠️ Note: All testnet contracts, tokens, and endpoints are for development and demonstration purposes only. Details may change as the rollup evolves.
