Toucan is building technology to move carbon credits onto open blockchains. It all starts with carbon credits. These represent a project’s planet-positive impact and are issued by standards bodies like Verra and Gold Standard. A Base Carbon Tonne is a fungible carbon token backed by a 1:1 verifiable link to carbon credits in a supported registry. Given BCT’s deep liquidity, it’s well-suited as a new building block for DeFi, DAOs, NFTs, and the metaverse.
