Please try it with a lower version of node, such as 10.18.1

I feel there are no more issues with the contract migration, but there are still a lot of issues with the non-contract parts, including the use of infrastructure such as Remix, Hardhat, and SDK.

[hthuang996]

Chainlink's node application uses Go-Ethereum, and when I completely replaced it with PlatON-Go, it didn't compile properly due to the following issues
1.Address
Ethereum uses EIP55 and PlatON uses Bech32, which is difficult to deal with and requires familiarity with the address principle.

2.The lack of code
Compared to Ethereum, PlatON removed some code, such as dynamic_fee_tx.go, access_list_tx.go, legacy_tx.go, these files could not be found. Also missing are functions and data structures such as ConvertType, MetaData, EncryptDataV3, and many others.

3.Data structure changes
GasFeeCap and GasTipCap fields are missing in CallMsg.
CryptoJSON was changed to cryptoJSON, causing external import to fail.
Ethereum's TxData is an interface, which PlatON does not have. Instead, it defines a structure named txdata. There is no func NewTx(inner TxData) *Transaction function.

I also found that a lot of code was not deleted, but was commented, I don't know why.

Any incompatibility issues with the underlying tools can be raised.
Then try to fix these infrastructure issues and adapt them to PlatON|Alaya, and submit the fixed code along with the documentation. The more deliverables you have and the more usable they are, the more you will be rewarded.

[biganxin]

these questions make sense, please add the question tag [issue+N]
I can get someone to assist you in confirming and fixing them

for question 1, we use bech32 in our address, relevant instructions are here .for specific usage, please refer to here.

for question2 and 3,These are the new features of Ethereum, PlatON not support yet, and we will consider supporting them in the future.

Solved, execute command:
