There was a BASE_GOERLI PR, that was closed due to not sufficient LP liquidities. Can you add LP liquidities on BASE_SEPOLIA?

[danielcrt]

@jsy1218 I saw there's also no liquidity on Ethereum Sepolia for ETH/USDC

What would be the min requirements to move this forward?
Is 1 ETH/USDC (0.3%) LP on Base Sepolia enough or do I have to create multiple tiers?
What's the min liquidity I have to provide?

I can create a ETH/USDC pool on Base Sepolia with ~100 ETH / 100 USDC.

I can create a ETH/USDC pool on Base Sepolia with ~100 ETH / 100 USDC.

~0.1 ETH / 300 USDC should be good enough. A single fee tier should be fine, I would create 0.05% instead of 0.3%, since 0.05% WETH/USDC is the most popular fee-tier pool on v3 L1.

I saw the WETH/USDC pool is already initialized: https://sepolia.basescan.org/address/0x94bfc0574ff48e92ce43d495376c477b1d0eeec0
But with a very bad ratio:
0.000000000000000001 WETH
0.900001 USDC

I tried to mint a new position and add liquidity in order to balance the pool but without success. Can you please guide me how to fix this imbalance? Or what other solution can I work towards?

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
