KIP-8: Introduce KLIMA/USDC bonds

Motivation

Currently, the official KLIMA liquidity ecosystem is a simple 2 pool setup: USDC/BCT, and KLIMA/BCT. For most users, the most liquid route to swap USDC for KLIMA first swaps USDC for BCT, then BCT to KLIMA.

This system was initially made to bootstrap a robust BCT/USDC pool to incentivize users to bridge offsets on-chain via Toucan. We feel that this liquidity pool has been made large enough today, $50m in BCT/USDC. The utilization rate of this pool is consistently under 10%, which signals to the policy team that we have accomplished the goal of facilitating a carbon market for BCT in the short term.

At a high level, as we grow, we can expand liquidity vertically or horizontally. By developing KLIMA horizontally, we place KLIMA at the heart of the on-chain carbon economy. This benefits Klima as every trade in the on-chain offset market generates more volume through KLIMA, allowing the ecosystem to grow further by channeling demand and fees into the Klima treasury.

The benefits of a KLIMA/USDC pool are the it lowers fees for the end user, provides higher capital efficiency, and a better alignment of demand
