Symbiosis launched SIS chain for cross-chain swaps

SIS Chain replaces third-party L2

Later this month, Symbiosis is launching the SIS Chain – a custom-built blockchain that will host all core protocol operations moving forward. As part of this, Symbiosis will transition from relying on third-party Layer 2 infrastructure to running its own dedicated chain. The move brings full operational control, faster upgrade cycles, and better alignment between protocol design and execution. Most importantly, it unlocks tighter integration between token utility and usage – all swaps, bridges, and operations on the SIS Chain will now consume $SIS.

$SIS becomes the SIS Chain’s native gas token

With the launch of the new Symbiosis Host Chain, the $SIS governance token will officially become the native gas token for all protocol operations. Users won’t need to bridge manually – cross-chain swaps and protocol interactions will automatically route through the SIS Chain as part of the backend architecture. Every transaction (whether a swap, bridge, or other cross-chain action) will now consume $SIS as gas. This creates a direct and structural link between usage of the protocol and demand for the $SIS token, reinforcing its utility at the core of the Symbiosis ecosystem.
