## Simple Summary

Implement an inflation schedule of 20,000 YFI over the next 8 years, with 12,802 distributed in the first 3 years, ending with a trailing tail of 1% inflation.

## Abstract

- Update the YFI mint contract to reflect new inflation schedule.

## Motivation

To create an inflation schedule after the passing of YIP-0.

**FOR**: Implement an inflation schedule of 20,000 YFI over the next 8 years, with 12,802 distributed in the first 3 years, ending with a trailing tail of 1% inflation.

**AGAINST**: No changes.

## Specification

### Overview

1. Adjust supply schedule to follow [[YFI Inflation Schedule](https://docs.google.com/spreadsheets/d/1yomUGpAWR8svL9RXD-_vL2ArgQPGj1x2XPNKDEuZR9Q/edit?usp=sharing)].

- Beginning annual inflation: 22.384%
- Weekly emissions reduction multiplier: 0.9937
- Week that terminal inflation starts: 416 weeks
- Fixed % ongoing inflation (tail emission): 1%

2. This model will stay in place until it is stopped or adjusted.

### Rationale

- Liquidity provider yields are maintained at reasonably competitive levels in various YFI price and TVL scenarios (see modeling sheet).
- Lower initial inflation (22%) to keep long-term rewards reasonable.
- 8 year emission schedule to support long-term development.
