Swapping Tokens

Aside from buying tokens via the CarbonPath web app (see Buying Tokens), tokens may also be exchanged via Uniswap. As defined in their website FAQs, “The Uniswap Protocol is an open-source protocol for providing liquidity and trading ERC20 tokens on Ethereum.” Using the Uniswap Interface, tokens can easily be exchanged. Steps in swapping CPCO2 tokens are as follows:

1. Access Uniswap Interface

2. Connect your wallet

3. Select tokens

4. Input swap amount

5. Confirm transactions
