Context

Quai Network is a Layer 1 blockchain designed for high throughput and parallel transaction execution. The network uses a multi-chain architecture consisting of Prime, Region, and Zone chains, which process transactions concurrently instead of relying on a single execution environment.

Quai is EVM-compatible, allowing existing Ethereum smart contracts and tooling to be used with minimal changes. The network runs on a Proof-of-Work–based consensus mechanism (PoEM) optimized for parallelism and fast block confirmation without introducing sharding-level coordination complexity.

The protocol operates with two native assets serving distinct roles: a primary gas token (QUAI) and a separate value-transfer asset (QI).

The Quai Network mainnet launched in early 2025. The network is currently focused on scalable EVM execution and infrastructure expansion rather than application-specific optimizations.

Proposal

Enable bridging functionality for Quai Network using Symbiosis smart contracts for the following assets:

• QUAI.Quai ↔ wQUAI.Ethereum
• QUAI.Quai ↔ wQUAI.Base
• USDT.Ethereum ↔ USDT.Quai

The integration will include the following steps:

• Deploy and configure Symbiosis bridging contracts on Quai Network, Ethereum, and Base to support wrapping and unwrapping QUAI and USDT.
• Activating the Symbiosis Relayers Network to work with the new blockchain.
• Extend Symbiosis protocol functionality to support QUAI.Quai ↔ wQUAI.Ethereum, QUAI.Quai ↔ wQUAI.Base and USDT.Ethereum ↔ USDT.Quai bridging.
• Add Pelagos wallet support to ensure reliable token interactions on Quai Network.

Key Points

• Supporting Quai at an early stage positions Symbiosis as a cross-chain routing layer for a growing ecosystem where asset mobility is expected to be a core requirement.
• Quai Network’s architecture primarily targets developers and infrastructure projects, with end-user benefits emerging indirectly through improved execution scalability and network stability.
• Integrating Quai expands Symbiosis coverage to high-throughput Layer 1 environments.
• Full EVM compatibility allows straightforward integration into Symbiosis without protocol-level adaptations.
