Deploy Polygon Amoy, drop Mumbai

[dtbuchholz]

Summary

Adds a new utility function to get live gas prices for Amoy and deploys new registry contracts there. Also, drops Mumbai.

Details

For some reason, ethers' built-in method getFeeData (which makes a call to get gas prices from a node) returns absurdly wrong data for Amoy. E.g., maxFeePerGas of 1000000030n and maxPriorityFeePerGas of 1000000000n—but in reality, these are 30x larger at 35185714305n and 35185714290n, respectively. Thus, an API call to the gas station is required. Note: there is a built-in custom gas fee class in ethers, but I couldn't figure out how to use it.

How it was tested

Deploying on live net.

i found this on some SO issue... might not be right

[dtbuchholz]

ah, yeah should be https://www.oklink.com/api/v5/explorer/contract/verify-source-code-plugin/AMOY_TESTNET. still can't get it to work tho:

We tried verifying your contract TablelandTables without including any unrelated one, but it failed.

• docs ref: here
• potentially, a known issue with hardhat: here

hmm, 500 error should mean it's an error on oklink's side, but who knows. is the browserUrl correct?

did you by change compile some changes after deploying? NomicFoundation/hardhat#1349 (comment)

[sanderpick]

might be worth doing a fresh build, deploy, and verify to make sure something weird didn't happen

[dtbuchholz]

hm, i didn't change the hardhat compiler version or any of the build settings, so i don't think it's that. but, if i change the compiler version to 0.8.20 and try to verify, it confirms that 0.8.19 is the correct version for the contract i deployed:

The contract you want to verify was compiled with solidity 0.8.19, but your configured compiler version is: 0.8.20.

based on the polygon discord, others are having the same issue with oklink. however, the polygon team noted polygonscan will be supporting amoy within the next 2-3 weeks, so it's probably a moot point.

edit: i tried rebuilding/deploying/verifying a new contract w/ my personal wallet. same result, couldn't verify

[sanderpick]

cool. sg!
