Axelar Gateway compatibility issues

This issue details the failing Gateway compatibility tests for Axelar.

Setup

Please follow the instructions in this link to set up your environment for live network testing. Additionally, you can use the provided configuration as a reference.

Replication

To run only the specified tests, add the only keyword to the following AxelarGateway tests:
Line 1024
Line 1077
Line 1135
Line 1694

Then run the following command:

npx hardhat test --network flow --grep AxelarGateway

Comparison

When the same commands are executed for other EVM-compatible chains, these tests should run smoothly. To verify this, use the following command:

npx hardhat test --network fantom --grep AxelarGateway

TL;DR

When running the AxelarGateway compatibility tests, some RPC calls fail for certain transactions without providing a clear error message. The response typically looks like this:

{
  "jsonrpc": "2.0",
  "id": 117,
  "error": { "code": -32000, "message": "internal error" }
}

This issue can be observed at this line.

Additionally, when running the Gateway tests, the gateway transaction does not produce the Transfer event as expected, unlike other chains. This can be tested at this line.

The text was updated successfully, but these errors were encountered:

@blockchainguyy Thanks for the detailed issue. I will follow your steps and run these commands locally, to see what could be causing the compatibility failures.

m-Peter · 2024-07-31T16:47:43Z

@blockchainguyy I was able to re-produce the failures locally, all the following tests:

fail with:

state error: invalid operation, can't selfdestruct an account that is just created

Can you point me to the function that is calling selfdestruct ?

Update:

blockchainguyy · 2024-08-01T09:21:47Z

Thanks @m-Peter ! Were you able to run test on Line 1077?

This is a different error on my end where the expected event is not emitted. I can still reproduce it on my end.

Sample tx: https://eth.flowscan.io/tx/0xf49c5e3fe972f9428ee366b41ca6603845fb9da8fb33ead462e4a35334f22c63?tab=logs

m-Peter · 2024-08-01T09:24:27Z

@blockchainguyy Yes, I was also able to reproduce this failure locally. I will prepare a local build with the fix in onflow/flow-go#6289, to see if this test is also related to the selfdestruct state error. And I also want to see if it will fix the other 3 errors.

m-Peter · 2024-08-01T09:47:19Z

@blockchainguyy I ran again the tests with the fix in onflow/flow-go#6289, and got:

AxelarGateway
    command burnToken
      burn token positive tests
burnToken external gas: 355039
        ✔ should allow the operators to burn external tokens (786ms)

AxelarGateway
    command burnToken
      burn token positive tests
        ✔ should allow the operators to burn the external token multiple times from the same address (881ms)

AxelarGateway
    external tokens
      ✔ should support external ERC20 token (928ms)

So we have 3/4 failing tests fixed. I still have to look into Line 1077.

m-Peter · 2024-08-01T10:30:14Z

@blockchainguyy So the test beginning at Line 1077 still fails, and If I comment this line it passes. I am not sure what is happening here, but I guess something to do with the fact that the deposit address already has some balance and selfdestruct is missing this particular case. Can you elaborate on what is the test doing, on a high-level?

blockchainguyy · 2024-08-01T13:45:32Z

@m-Peter This test sends some ethers (native token of the chain), as well as an ERC20 token on a destination contract before it is created.

Then when the execute function is called, the destination contract is deployed and self destructs in the same transaction. Before it self destructs, it sends the ERC20 tokens as well as Ether to the Gateway contract.

Some guesses on what could be wrong:

Does having balance change your [isContract](https://github.com/axelarnetwork/axelar-cgp-solidity/blob/be9f5c29b1ca4db788f59ff31c667c502d76211a/contracts/AxelarGateway.sol#L613)() implementation?
Having ether in the contract removes events from the mined transaction

Note: you should also check ethers are transferred to the gateway when it selfdestructs.

m-Peter · 2024-08-01T14:00:46Z

@blockchainguyy After some digging, I found out that in this particular case, the burnToken function returns early on this line.
Which is exactly what you mentioned above, on the first bullet 😅
I'll need to investigate further 🙏

blockchainguyy · 2024-08-01T14:22:56Z

@m-Peter this is the function which is failing: https://github.com/axelarnetwork/axelar-gmp-sdk-solidity/blob/3157ba4f704de408e356ad8236b5d81bbc82d7cb/contracts/libs/ContractAddress.sol#L6

Maybe you are storing some data on the address if you send native tokens to the contract which would be different from other EVMs.

m-Peter · 2024-08-01T15:12:09Z

@blockchainguyy To try something out, I by-passed the if (depositHandlerAddress.isContract()) return; condition,
but then the transaction reverts when coming across this line:

DepositHandler depositHandler = new DepositHandler{ salt: salt }();

Why could that be?

m-Peter · 2024-08-02T11:32:51Z

@blockchainguyy I have found the root cause of this test failure, it is basically a contract address collision, when it encounters this line:

DepositHandler depositHandler = new DepositHandler{ salt: salt }();

given that the depositHandlerAddress already has received a transfer.
When the above address has not received any transfer, we get:

Nonce:  0
StorageRoot:  0x0000000000000000000000000000000000000000000000000000000000000000

but when it has received a transfer, we get:

Nonce:  0
StorageRoot:  0xc5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470

I see, let me try to reproduce

ramtinms · 2024-08-06T01:16:52Z

This should fix the issue onflow/flow-go#6295

m-Peter · 2024-08-06T10:55:06Z

@blockchainguyy The fix linked above does indeed fix the issue for the last failing test:

AxelarGateway
    command burnToken
      burn token positive tests
burnToken external gas: 355059
        ✔ should allow the operators to burn external tokens (617ms)
        ✔ should allow the operators to burn external tokens even if the deposit address has ether (738ms)
        ✔ should allow the operators to burn the external token multiple times from the same address (626ms)
    external tokens
      ✔ should support external ERC20 token (709ms)


  4 passing (5s)

Are there any other test suites that I should try out? For example, I noticed that AxelarGatewayUpgrade has 1 failure. And RpcCompatibility seems like a good candidate to try out as well.

AxelarGatewayUpgrade
    ✔ should deploy gateway with the correct modules (137ms)
    1) should upgrade AxelarGateway through InterchainGovernance proposal

@m-Peter can you supply gas option like this in your local version axelar-chains-config/info/testnet.json:

    "flow": {
      "name": "flow",
      "id": "flow",
      "axelarId": "flow",
      "chainId": 646,
      "rpc": "https://previewnet.evm.nodes.onflow.org",

      "gasOptions": {
        "gasLimit": 10000000
      },
      "confirmations": 0
    }

once I specify gasLimit, I am able to run these tests without hiccups:

  AxelarGatewayUpgrade
    ✔ should deploy gateway with the correct modules (4598ms)
    ✔ should upgrade AxelarGateway through InterchainGovernance proposal (70704ms)


  2 passing (3m)

You can ignore the failing RPC, its just to flag on our end if a chain's gas calculation is different from normal EVM, our SDK team should be able to handle it using your docs (if it is properly documented).

m-Peter · 2024-08-07T11:03:21Z

@blockchainguyy I am continuing the investigation of those failures.

Regarding the gas calculation, Flow EVM has the same gas calculation like normal EVM, it is just that for eth_estimateGas, we add some buffer gas, in order to make sure that the return value is sufficient for a transaction to execute successfully. This is only for certain edge cases. See: https://github.com/onflow/flow-go/blob/master/fvm/evm/emulator/emulator.go#L291-L308.
I did check the values, and the gas used is indeed 27_613, which is less than 30_000.

I am running these tests on a local JSON-RPC server, to make sure that it works with the latest changes.
I am still getting these failures:

AxelarGatewayUpgrade
    ✔ should deploy gateway with the correct modules (137ms)
    1) should upgrade AxelarGateway through InterchainGovernance proposal


  1 passing (14s)

Do I need any special setup for should upgrade AxelarGateway through InterchainGovernance proposal ?

With the addition of https://eips.ethereum.org/EIPS/eip-6780, does this test make any sense now? It shouldn't be possible to selfdestruct a contract in a future transaction.

blockchainguyy · 2024-08-08T07:17:58Z

Regarding the gas calculation, Flow EVM has the same gas calculation like normal EVM, it is just that for eth_estimateGas, we add some buffer gas, in order to make sure that the return value is sufficient for a transaction to execute successfully. This is only for certain edge cases. See: https://github.com/onflow/flow-go/blob/master/fvm/evm/emulator/emulator.go#L291-L308.

eth_estimateGas should try to provide actual estimates, because buffers are already added by providers broadcasting the transaction, and it can block users with limited balance to interact with your nodes even if they have enough balance to transact. Anyway, not a blocker for us to integrate so it can be handled separately.

No need to run DepositHandler tests for comaptibility, our new amplifier gateway (which will be deployed on Flow) has removed selfdestruct so it won't be needed.

For AxelarGatewayUpgrade pls set gasOptions in you testnet config as done here: https://github.com/axelarnetwork/axelar-contract-deployments/blob/218b366103b2f1fc9c0a9ad602758725b50b5392/axelar-chains-config/info/testnet.json#L114

I have shared my config setting in this comment already: #404 (comment)

estimateGas is not able to calculate gas for the required upgrade properly and hence we need to specify the limit explicitly.

There is a sense of urgency on our end to proceed with integration, so if things could be merged and deployed quickly it would be great.

  24 passing (7s)

I have made a minor change for the eth_estimateGas test case:

expect(gas).to.be.lt(30500);

m-Peter · 2024-08-08T09:48:15Z

eth_estimateGas should try to provide actual estimates, because buffers are already added by providers broadcasting the transaction, and it can block users with limited balance to interact with your nodes even if they have enough balance to transact. Anyway, not a blocker for us to integrate so it can be handled separately.

Let me explain how gas estimation works for Flow EVM compared to normal Ethereum. Ethereum will repeatedly run a transaction, based on the given transaction arguments, with different gas limits until it finds the lowest gas limit that allows the transaction to run.
Flow EVM, on the other hand, will do a dry run of the transaction without committing the state. This will return the actual gas used from the transaction. However, in order to run the transaction, the gas limit has to be higher in many cases, although it won't be consumed. This is for cases such as refunds for slot clearance, prevention of re-entrancy attacks, and create / create2 opcodes.

No need to run DepositHandler tests for comaptibility, our new amplifier gateway (which will be deployed on Flow) has removed selfdestruct so it won't be needed.

Sounds good 👍

For AxelarGatewayUpgrade pls set gasOptions in you testnet config as done here: https://github.com/axelarnetwork/axelar-contract-deployments/blob/218b366103b2f1fc9c0a9ad602758725b50b5392/axelar-chains-config/info/testnet.json#L114

I have shared my config setting in this comment already: #404 (comment)

estimateGas is not able to calculate gas for the required upgrade properly and hence we need to specify the limit explicitly.

I still can't get this to run locally, but I am able to run it against PreviewNet. So maybe something is wrong with my local setup. But as long as you can run it against the live network, then it should be good.

Then we just have to be sure the merge does not break things. :) Thanks @m-Peter! 🙌🏼

m-Peter · 2024-08-08T11:24:49Z

@blockchainguyy Thanks for the guidance on running these tests 🙇
Let's hope things will run smoothly on PreviewNet, after we deploy those fixes 🙏

Then we just have to be sure the merge does not break things. :) Thanks @m-Peter! 🙌🏼

@blockchainguyy I was finally able to find out why this AxelarGatewayUpgrade test fails locally 🙏
This is the result of eth_getTransactionReceipt:

    "transactionIndex": "0x0",
    "type": "0x0"
  }
}

From the revertReason, we see that the revert is coming from this line: https://github.com/axelarnetwork/axelar-gmp-sdk-solidity/blob/main/contracts/utils/TimeLock.sol#L76.
This is because, when running the JSON-RPC locally against the Flow Emulator, there are basically no delays between blocks, it runs very fast. That's why the test succeeds on a live network, such as PreviewNet, but fails locally.
So after this, I think we are on a good state, and we're just waiting for a deployment on the necessary changes on PreviewNet 🙏 .

m-Peter · 2024-08-11T09:46:19Z

@blockchainguyy The fixes listed above have been deployed on PreviewNet, here are the results of running the Axelar Gateway testing suites:

AxelarGateway
    command burnToken
      burn token positive tests
burnToken external gas: 355051
        ✔ should allow the operators to burn external tokens (69023ms)

    eth_estimateGas
      ✔ should support RPC method eth_estimateGas like ethereum mainnet (230ms)
      ✔ should send tx with estimated gas (17832ms)
    eip-1559 supported rpc methods
      ✔ should support RPC method eth_maxPriorityFeePerGas (16790ms)
      ✔ should send transaction based on RPC method eth_feeHistory pricing (16283ms)


24 passing (3m)

All tests on RpcCompatibility test file, are now passing 🎉
Note: For this I made the following change locally:

// before
expect(gas).to.be.lt(30000);
// after
expect(gas).to.be.lt(30500);

This is due to the buffer gas which I described that we make use of in eth_estimateGas. We will re-work this, in the coming days. But it should be good for now.

Let me know if everything's looking good, so we can close the issue 🙏
