Summary

As described in GIP-201, Mellow vaults migration made it incompatible with previously used price feeds & deposit adapters. Now the migration is done and it’s proposed to deploy upgraded integration contracts.

It’s also proposed do add new liquidity sources for Mellow LRTs.

Compatibility (zero price feed):

• Curve stable ng pzETH/wstETH (0xcec99cff3632cf1f16652cc5b1e80eb08be25983)

Trade WETH v3 Pool

Increase quota limits to match existing level of dex liquidity:

Asset	pzETH	Re7LRT	amphrETH
Quota Limit	1000	400	700

Add new quoted token (compatibility: quotaLimit = 0; minRate = 0.01%; maxRate = 0.01%):

• Curve stable ng pzETH/wstETH (0xcec99cff3632cf1f16652cc5b1e80eb08be25983)

Restaking WETH CM

Add new collateral token (compatibility: LT = 0):

• Curve stable ng pzETH/wstETH (0xcec99cff3632cf1f16652cc5b1e80eb08be25983)
