• Governance and staking contract.
• YFL can be staked to participate in voting or make proposals (arbitrary code execution).
• Anyone can execute a successful proposal.

• Provides token amounts for ETH or LINK, given a USD amount.
• Based on Uniswap's ExampleOracleSimple.
• Used by LinkswapFactory for listing fee calculation and minimum listing lockup amount calculation.
• Can be swapped out via a governance proposal later if necessary.

• Handles the creation of new pairs, and stores variables that apply to new and existing pairs.
• All variables can be changed via a governance proposal.

• Contract created via LinkswapFactory for each pair.
• Based on UniswapV2Pair, with added functionality of timelocking liquidity and a circuit-breaker that prevents slippage of prices beyond a certain percent in either direction in a certain timeframe.
• Fees are customizable per-pair via a governance proposal.

• Contract based on UniswapV2Router and used for convenience by front-end.
• Has been modified to account for dynamic fees (set in LinkswapPair).
