NOTES

Additional relevant information:

We need separate pairs for STORJ/USD, ETH/USD and USDC/USD prices on zkSync networks (both testnet and mainnet).

For the STORJ/USD and ETH/USD pairs, we would like to have deviation-based delivery method with 5% deviation.

For the USDC/USD price feed, we would go with 1% deviation-based trigger

All assets will be updated every 24h period if there are no deviation based updates
