EVM Test Suite

The commands (script) will clone and run the contract tests [compound, synthetix, uniswap, ...] against the Ethermint's EVM. This test will comprehensively check the EVM against that of Ethereum's to verify that the results show the exact same behaviour.

Test Suites

The following are instructions on how to run the specified EVM test suite on the Ethermint network.

Synthetix

Copy # Start the ethermint node and expose rpc endpoint on :8545 # this can be done by running `./init.sh` in the ethermint dir # Synthetix git clone https://github.com/Synthetixio/synthetix.git cd synthetix npm install npm install web3 npm i -g yarn yarn add hardhat npx hardhat compile npx hardhat test --network development

Uniswap

Copy # Start the ethermint node and expose rpc endpoint on :8545 # this can be done by running `./init.sh` in the ethermint dir # Uniswap v3 git clone https://github.com/Uniswap/uniswap-v3-core.git yarn install npx hardhat compile

Add ethermint network in hardhat.config.ts

Copy networks: { ethermint: { url: 'http://127.0.0.1:8545', accounts: 'remote', gas: 'auto', gasPrice: 'auto', gasMultiplier: 1, timeout: 20000 } } Copy # run the test suite npx hardhat test --network ethermint

Compound

Copy # Start the ethermint node and expose rpc endpoint on :8545 # this can be done by running `./init.sh` in the ethermint dir git clone https://github.com/compound-finance/compound-protocol.git npm install npx addle compile

Add ethermint network in saddle.config.ts

Copy networks: { ethermint: { providers: [ {env: "PROVIDER"}, {http: "http://127.0.0.1:8545"} ], web3: { gas: [ {env: "GAS"}, {default: "4600000"} ], gas_price: [ {env: "GAS_PRICE"}, {default: "12000000000"} ], options: { transactionConfirmationBlocks: 1, transactionBlockTimeout: 5 } }, accounts: [ {env: "ACCOUNT"}, {unlocked: 0} ] }, } Copy # run the test suite npx saddle test -n ethermint

Known Issues:

1. ether.js is not compatible with Ethermint. Currently, Ethermint is unable to interact with the test suites and there is a slight incompatibility with ethers.js. The issue has been documented and has been in the icebox for some time (https://github.com/cosmos/ethermint/issues/349).

In the future, when compatible with ethers.js, the test suites can be run with the simple command and will be run against the Ethermint EVM. If the all of the tests pass without incident, the Ethermint EVM implementation can be deemed to produce the same output as the Ethereum EVM.

2. For Uniswap V3, Hardhat tests only work for hardhat test network when loading the node accounts.
3. For Compound, some tests are failing in their CI.
