# Bridging Gauge The Bridging Gauge incentivizes those who bridge on-chain with governance tokens. With carbon assets, currently supply is only expanded when users bridge their carbon credits on chain. By giving governance to those who bridge, it significantly accelerates the supply on chain. C3T-ERC20s that are able to go into the following tokens will be eligible for bridging rewards: * **UBO** * **NBO** Unlike the Staking and Liquidity Gauge, only C3T-ERC20s are able to be incentivized. As more Carbon Pool Tokens are added into gauges, and therefore more C3T-ERC20s are able to be accepted, the criteria becomes bigger and bigger. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.c3.app/carbonomics/bridging-gauge.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
