Toucan Protocol

Toucan builds infrastructure for carbon credit tokenization, having brought over $100 million in carbon credits on-chain and enabled $4 billion in transactional volume. The protocol's Carbon Bridge tokenizes verified credits from Verra and Puro.earth registries as TCO2 tokens, while Carbon Pools bundle similar credits into liquid index tokens like BCT (Base Carbon Tonne) and NCT (Nature Carbon Tonne). Toucan represents 85% of all digital carbon credits.
