maybe HTS specific functions should be placed under its own module, e.g., utils/hts.js, to avoid polluting this web3.js module

evm-functional-testing/test/hip-1340/hiero.test.js

we could rename this to hts.test.js given at the moment contains HTS related tests.

Additional Hiero specific tests could be placed in their own file.

sure, will rename

nit: all amounts, either HBAR or token's should be bigints for consistency

await waitFor(tokenCreateContract.transferTokenPublic(tokenAddress, eoa1.address, 5_000));

await waitFor(tokenCreateContract.transferTokenPublic(tokenAddress, eoa1.address, 5_000n));

if log is not used, we can remove it

Good catch, I used to use it, but no longer the case

+
+        const [eoa1Nonce, eoa2Nonce, receiverNonce] = [new Nonce(), new Nonce(), new Nonce()];


Given that eoa1Nonce, et. all refers to the same nonce (no aliases) we could use Number instead, right?

I guess, I followed example here https://github.com/hashgraph/hedera-evm-testing/pull/71/changes#diff-f6817b63d43af1bcbe4015dde3b6e7b16529cd882f1d5f3743ec046e8eeec713L152

+        expect(anotherAddressBalance).to.be.equal(1000);
+
+        // Verify the HTS token address has a delegation designator pointing to 0x167


At the moment it can be verified by checking both ContractByteCodeQuery and AccountInfo.delegationAddress from CN, something like

const [code, contractBytecode, delegationAddress] = await web3.getCodes(eoa.address); // TODO(pectra): Reenable check once MN and Relay include support for EIP-7702 // expect(code).to.be.equal(designatorFor(delegateAddress)); expect(contractBytecode).to.be.equal(designatorFor(delegateToAddress)); expect(delegationAddress).to.be.equal(delegateToAddress);

const [code, contractBytecode, delegationAddress] = await web3.getCodes(eoa.address);

Does not seem to work. In my case that won't be eoa, but contract address. And we call mirror node accounts endpoint underneath. I tried using contracts endpoint instead, but mirror node did not return any info. Will look further, to see how that code can be adapted for this case.

+        // Deploy TokenCreateContract and create HTS fungible token
+        const tokenCreateContract = await Utils.deployTokenCreateContract();


why do we need to deploy a token contract here?

One way to create HTS is to use the SDK. Another way to do it is via this helper contract that is used in other test. This way we are doing it via EVM only (no native/SDK).

Oh I see, so then maybe we can parameterize this test by using both EVM and SDK HTS tokens.

@acuarica addressed most comments. Looking further into why below suggestion did not work as expected

const [code, contractBytecode, delegationAddress] = await web3.getCodes(eoa.address);
// TODO(pectra): Reenable check once MN and Relay include support for EIP-7702
// expect(code).to.be.equal(designatorFor(delegateAddress));
expect(contractBytecode).to.be.equal(designatorFor(delegateToAddress));
expect(delegationAddress).to.be.equal(delegateToAddress);

Fixed this, by querying the token endpoint instead.
