Using our risk framework and Uniswap V3 price impact tool we give LINK a strong oracle rating.
This report is related to eIP 6.
For maximum security of the oracle, it needs to fulfil 3 criteria:
- Liquidity is provided over the full price range
- Elevating the TWAP (Time-Weighted-Average-Price) to a meaningful extent is impossible or extremely costly.
- Depressing the TWAP to a meaningful extent is impossible or extremely costly.
LINK/WETH appears to have full range liquidity (non-zero% is 100%) provided by a multitude of liquidity providers (64895 initialised #).
We have analysed the cost of moving the TWAP of XYZ/WETH by 20% up and down over 1 to 10 blocks. The results are:
This shows that manipulating the TWAP over a 1-2 block attack (the most realistic for an attacker) would cost at least $639 million, which is clearly not feasible.
Given the presence of full-range liquidity and substantial cost of attack, we give the asset above a strong oracle rating.
