Polygon
Each BCT represents one verified carbon credit (tonne of CO2) from the Verra registry meeting the pool's acceptance criteria, bridged and made fungible through Toucan's infrastructure on Polygon. BCT established the reference liquidity pool for on-chain voluntary carbon.
One tonne of verified carbon, bridged on-chain.
Prism analyst note
BCT is a lesson in commodity-quality dynamics: the pool's broad acceptance criteria attracted older vintage credits, and prices collapsed with the wider voluntary carbon market after 2022. It remains the most liquid on-chain carbon instrument and a functional retirement rail, but should be treated as a speculative environmental commodity, not a stable store of value. Newer selective pools command premiums over BCT.
