# FAQ for transition to Open Source

This page provides more details on the May 2025 strategic announcement to incrementally transition Toucan Protocol to Open Source licenses.  The summary is that this transition will cause no significant changes to tokens or existing infrastructure.

* **What will happen to my CHAR?**

  There will be no significant change. CHAR will continue to be available on Base and Celo, with cross-chain bridging remaining available between these chains. On/off-chain bridging of underlying TCO2s will continue to be supported via our Puro Bridge. Deposits/redemptions will continue to be supported at [app.toucan.earth](http://app.toucan.earth). Liquidity will remain at the discretion of liquidity providers, as before.
* **What will happen to my NCT?**

  No significant change. Cross-chain bridging will remain available between Polygon, Celo, and Regen. Deposits/redemptions will continue to be supported at [app.toucan.earth](http://app.toucan.earth).
* **What will happen to my BCT?**

  BCT is no longer a Toucan product, as admin control of the BCT contracts was transitioned to KlimaDAO in 2024. While there will be no significant changes, cross-chain bridging is deprecated - please inquire with KlimaDAO regarding bridge availability. Deposits/redemptions will continue to be supported at [app.toucan.earth](http://app.toucan.earth). Liquidity will remain at the discretion of liquidity providers.
* **What will happen to my TCO2s?**

  There will be no significant changes to TCO2s. Puro TCO2s eligible for the CHAR carbon pool can continue to be deposited and redeemed. On/off-chain bridging and retirement of Puro TCO2s will continue to be supported for the foreseeable future. Verra TCO2s will continue to be eligible for BCT and selectively, NCT as well. Note that Verra credits not already tokenized are not eligible for tokenization and have not been since 2022. All Verra TCO2s will continue to be retirable at any time.
* **Will my existing tokens and assets remain secure during and after the transition?**

  We don't anticipate any impact to the security of your assets.
* **Who will govern and make decisions for the project?**

  There will be no significant changes. We welcome community input on the structure moving forward.
* **What will happen to the bridge to Puro.earth?**

  This will continue to remain operational.
* **How can I get involved in the open source project?**

  Reach out to us on [Discord](https://toucan.earth/discord) or via [GitHub](https://github.com/ToucanProtocol).
* **Will there be any changes to the existing smart contracts?**

  We will be open sourcing our smart contracts. Any maintenance and development of smart contracts will be handled along the same lines as before.
* **Will the code continue to undergo regular audits?**

  Smart contract upgrades and new deployments will continue to be audited.
* **How will security and maintenance be handled going forward?**

  Security and maintenance procedures for smart contracts will be handled along the same lines as before.
* **Will there be any changes to fees or cost structures?**

  No.
