Strengthening Stablecoin Infrastructure on Zilliqa: Introducing zUSDC via XBridge
Stablecoins play a foundational role in decentralized ecosystems, enabling liquidity, trading efficiency, and interoperability across markets.
As Zilliqa continues building Regulatory-ready and Institutionally aligned blockchain infrastructure, we are strengthening how stablecoin liquidity operates within the network.
Today, we are introducing zUSDC, a USDC representation powered by Zilliqa’s native XBridge infrastructure.
This transition strengthens Zilliqa’s control over critical financial infrastructure while ensuring stablecoin liquidity continues to operate seamlessly across the ecosystem.
What is zUSDC?
zUSDC is a representation of USDC bridged to Zilliqa through the network’s native XBridge infrastructure.

The migration process involves:
- Bridging existing USDC liquidity back to Ethereum
- Minting zUSDC under Zilliqa-managed infrastructure
- Re-bridging funds to Zilliqa via XBridge
- Redeploying liquidity into ecosystem trading pools
For users, zUSDC continues to support the same core functionality, including:
- Stablecoin trading liquidity
- DEX liquidity pool participation
- Arbitrage opportunities across stable pairs such as kUSDC, zUSDT, and zUSDC
Why This Change Is Being Made?
USDC liquidity has historically been available on Zilliqa through third-party bridging infrastructure. While this enabled early ecosystem access, current usage patterns show that most stablecoin liquidity is concentrated within DEX pools supporting trading and arbitrage activity.
Operating external infrastructure under these conditions introduces operational dependency without proportional ecosystem benefit.
To improve long-term reliability and infrastructure sovereignty, Zilliqa is transitioning stablecoin liquidity to native infrastructure through XBridge. This ensures sustainable operations while maintaining uninterrupted ecosystem functionality.
This transition also aligns with Zilliqa’s broader strategy of building Institutionally compatible blockchain infrastructure, where critical financial rails are operated directly by the network.
Migration Timeline
The transition occurs in phased stages designed to minimize ecosystem disruption.
Phase 1 - Preparation (Completed)
- Deployment of zUSDC support via XBridge
Phase 2 - Liquidity Migration (Completed)
- Existing bridged USDC unwound via Ethereum
- Liquidity re-bridged through XBridge
- Deployment of zUSDC liquidity
Phase 3 - Ecosystem Rollout (Completed)
- Public introduction of zUSDC
- Launch of zUSDC trading pair on Plunderswap
Phase 4 - Legacy Infrastructure Sunset
- Debridge support on Zilliqa will sunset on 31 March 2026
Impact on Users
Users holding USDC on Zilliqa should bridge their assets out via Debridge as soon as possible.
Available Debridge widget:
After 31 March 2026, Debridge will no longer operate on Zilliqa.
Any user holding USDC on Zilliqa after this date will need to email Zilliqa team for support, [email protected].
This transition does not remove stablecoin liquidity from Zilliqa. Instead, liquidity is being migrated to network-operated infrastructure to improve long-term stability and operational resilience.
Operational Enhancements
Alongside the launch of zUSDC, Zilliqa is improving XBridge operations to enhance reliability and processing efficiency.
Xbridge UI overhaul has already started. Check out Xbridge with brand new and clean UI https://xbridge.zilliqa.com.
While XBridge settlements are not instant, we currently work on progressive automation of bridge transaction processing that will bring back seamless token transfer across all supported chains.
Looking Ahead
The launch of zUSDC marks another step in Zilliqa’s evolution toward Native financial infrastructure.
As the ecosystem expands across Institutional integrations, RWA platforms, and Cross-chain financial infrastructure, maintaining control over critical network components becomes increasingly important.
Long-term ecosystems are built on infrastructure they own and operate.
