將 Optimism OP 轉換為 Base Carbon Tonne BCT

Optimism is a network of chains called the Superchain, built on the open-source OP Stack. OP Mainnet was the first chain, with several others now operating on the OP Stack architecture, including Base (by Coinbase), Unichain (by Uniswap), Ink (by Kraken), and World Chain (by Worldcoin). The OP Stack serves as a framework for Ethereum Layer 2 chains and supports significant L2 activity. Every OP Chain in the Superchain contributes back to the Optimism Collective and all chains follow a standardized revenue-sharing model: the greater of 2.5% of total chain revenue or 15% of onchain profit (defined as fees minus L1 gas costs) is paid back to the Optimism. By aligning economic incentives across many chains, Optimism aims to transform Ethereum scaling into a sustainable flywheel by delivering fast, low-cost transactions while reinvesting in the future of the ecosystem. OP holders participate in governance to shape protocol upgrades, funding decisions, and more

Base Carbon Tonnes (BCT) is a reference token representing one tonne of carbon from the Verra Verified Carbon Unit (VCU) registry from 2008 or later, bridged by the Toucan Protocol. Verra is the dominant voluntary carbon credit issuer and each VCU minted in their registry represents a real emissions saving from a project, that has been measured and audited by independent third parties. The Toucan Bridge is the first to allow any user to bridge their VCUs into crypto, and because it is a fungible ERC 20 token it can directly be integrated into any DeFi application. BCT is a foundational building block to enable an open regenerative finance ecosystem.
