When 42 | [a development chain is started](https://github.com/substrate-developer-hub/substrate-node-template#run), 43 | Alice's EVM account will be funded with a large amount of Ether (`U256::MAX`). The 44 | [Polkadot UI](https://substrate.dev/docs/en/next/development/front-end/polkadot-js#polkadot-js-apps) 45 | can be used to see the details of Alice's EVM account. In order to view an EVM account, use the 46 | `Developer` tab of the Polkadot UI `Settings` app to define the EVM `Account` type: 47 | 48 | ```json 49 | "Account": { 50 | "nonce": "U256", 51 | "balance": "U256" 52 | } 53 | ``` 54 | 55 | Use the `Chain State` app's `Storage` tab to query `evm > accounts` with Alice's EVM account ID 56 | (`0x57d213d0927ccc7596044c6ba013dd05522aacba`); the value that is returned should be: 57 | `{"nonce":0,"balance":"0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff"}`. 58 | 59 | > Further reading: 60 | > [EVM accounts](https://github.com/danforbes/danforbes/blob/master/writings/eth-dev.md#Accounts) 61 | 62 | Alice's EVM account ID was calculated using 63 | [a provided utility](/utils/README.md#--evm-address-address). 64 | 65 | ## Contract Deployment 66 | 67 | The [`truffle`](/truffle) directory contains a [Truffle](https://www.trufflesuite.com/truffle) 68 | project that defines [an ERC-20 token](/truffle/contracts/MyToken.sol). For convenience, this 69 | repository also contains 70 | [the compiled bytecode of this token contract](/truffle/build/contracts/MyToken.json#L259), which 71 | can be used to deploy it to the Substrate blockchain. 72 | 73 | > Further reading: 74 | > [the ERC-20 token standard](https://github.com/danforbes/danforbes/blob/master/writings/eth-dev.md#EIP-20-ERC-20-Token-Standard) 75 | 76 | Use the Polkadot UI `Extrinsics` app to deploy the contract from Alice's account (submit the 77 | extrinsic as a signed transaction) using `evm > create` with the following parameters: 78 | 79 | ``` 80 | init: 81 | value: 0 82 | gas_limit: 4294967295 83 | gas_price: 1 84 | ``` 85 | 86 | The values for `gas_limit` and `gas_price` were chosen for convenience and have little inherent or 87 | special meaning. 88 | 89 | While the extrinsic is processing, open the browser console and take note of the output. Once the 90 | extrinsic has finalized, the EVM pallet will fire a `Created` event with an `address` field that 91 | provides the address of the newly-created contract. In this case, however, it is trivial to 92 | [calculate this value](https://ethereum.stackexchange.com/a/46960): 93 | `0x11650d764feb44f78810ef08700c2284f7e81dcb`. That is because EVM contract account IDs are 94 | determined solely by the ID and nonce of the contract creator's account and, in this case, both of 95 | those values are well-known (`0x57d213d0927ccc7596044c6ba013dd05522aacba` and `0x0`, respectively). 96 | 97 | Use the `Chain State` app to view the EVM accounts for Alice and the newly-created contract; notice 98 | that Alice's `nonce` has been incremented to `1` and her `balance` has decreased. Next, query 99 | `evm > accountCodes` for both Alice's and the contract's account IDs; notice that Alice's account 100 | code is empty and the contract's is equal to the bytecode of the Solidity contract. 101 | 102 | ## Contract Storage 103 | 104 | The ERC-20 contract that was deployed inherits from 105 | [the OpenZeppelin ERC-20 implementation](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol) 106 | and extends its capabilities by adding 107 | [a constructor that mints a maximum amount of tokens to the contract creator](/truffle/contracts/MyToken.sol#L8). 108 | Use the `Chain State` app to query `evm > accountStorage` and view the value associated with Alice's 109 | account in the `_balances` map of the ERC-20 contract; use the ERC-20 contract address 110 | (`0x11650d764feb44f78810ef08700c2284f7e81dcb`) as the first parameter and the storage slot to read 111 | as the second parameter (`0xa7473b24b6fd8e15602cfb2f15c6a2e2770a692290d0c5097b77dd334132b7ce`). The 112 | value that is returned should be 113 | `0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff`. 114 | 115 | The storage slot was calculated using 116 | [a provided utility](/utils/README.md#--erc20-slot-slot-address). 117 | 118 | > Further reading: 119 | > [EVM layout of state variables in storage](https://solidity.readthedocs.io/en/v0.6.2/miscellaneous.html#layout-of-state-variables-in-storage) 120 | 121 | ## Contract Usage 122 | 123 | Use the `Extrinsics` app to invoke the `transfer(address, uint256)` function on the ERC-20 contract 124 | with `evm > call` and transfer some of the ERC-20 tokens from Alice to Bob. 125 | 126 | ``` 127 | target: 0x11650d764feb44f78810ef08700c2284f7e81dcb 128 | input: 0xa9059cbb0000000000000000000000008bc395119f39603402d0c85bc9eda5dfc5ae216000000000000000000000000000000000000000000000000000000000000000dd 129 | value: 0 130 | gas_limit: 4294967295 131 | gas_price: 1 132 | ``` 133 | 134 | The value of the `input` parameter is an EVM ABI-encoded function call that was calculated using 135 | [the Remix web IDE](http://remix.ethereum.org); it consists of a function selector (`0xa9059cbb`) 136 | and the arguments to be used for the function invocation. In this case, the arguments correspond to 137 | Bob's EVM account ID (`0x8bc395119f39603402d0c85bc9eda5dfc5ae2160`) and the number of tokens to be 138 | transferred (`0xdd`, or 221 in hex). 139 | 140 | > Further reading: 141 | > [the EVM ABI specification](https://solidity.readthedocs.io/en/v0.6.2/abi-spec.html) 142 | 143 | After the extrinsic has finalized, use the `Chain State` app to query `evm > accountStorage` to see 144 | the ERC-20 balances for both Alice and Bob. 145 | 146 | ## Polkadot UI 147 | 148 | This project contains [a Polkadot UI](/ui) with some custom components for the EVM pallet. 149 | 150 | ## Raspberry Pi 151 | 152 | See [the `rpi` directory](/rpi) for information about cross-compiling a Substrate node for execution 153 | on a Raspberry Pi. 154 | -------------------------------------------------------------------------------- /build.rs: -------------------------------------------------------------------------------- 1 | use vergen::{ConstantsFlags, generate_cargo_keys}; 2 | 3 | const ERROR_MSG: &str = "Failed to generate metadata files"; 4 | 5 | fn main() { 6 | generate_cargo_keys(ConstantsFlags::SHA_SHORT).expect(ERROR_MSG); 7 | 8 | build_script_utils::rerun_if_git_head_changed(); 9 | } 10 | -------------------------------------------------------------------------------- /makefile: -------------------------------------------------------------------------------- 1 | init-wasm : 2 | ./scripts/init.sh 3 | 4 | build-chain : init-wasm 5 | cargo build --release 6 | 7 | purge-chain : 8 | ./target/release/substrate-evm purge-chain --dev 9 | 10 | clean-chain : purge-chain 11 | rm -fr ./target 12 | 13 | start-chain : 14 | ./target/release/substrate-evm --dev 15 | 16 | build-ui : 17 | cd ./ui && yarn 18 | 19 | clean-ui : 20 | rm -fr ./ui/node_modules 21 | 22 | start-ui: 23 | cd ui && yarn start 24 | 25 | podman-build : 26 | podman build --tag subpi:latest ./rpi/ 27 | 28 | pi-build : podman-build 29 | ./rpi/pi-build.sh 30 | -------------------------------------------------------------------------------- /rpi/Dockerfile: -------------------------------------------------------------------------------- 1 | FROM rust:latest 2 | 3 | RUN dpkg --add-architecture armhf && \ 4 | apt-get update && apt-get upgrade -y && \ 5 | apt-get install -y aptitude && \ 6 | aptitude install -y \ 7 | gcc-arm-linux-gnueabihf \ 8 | libgtk-3-dev:armhf \ 9 | pkg-config \ 10 | libasound2-dev:armhf \ 11 | g++-arm-linux-gnueabihf \ 12 | cmake \ 13 | libssl-dev \ 14 | git \ 15 | clang \ 16 | libclang-dev \ 17 | libssl-dev:armhf \ 18 | libsdl2-dev:armhf 19 | 20 | # Install nightly with w32-u-u and add arvm7 to stable 21 | RUN rustup target add armv7-unknown-linux-gnueabihf 22 | RUN rustup install nightly && \ 23 | rustup target add wasm32-unknown-unknown --toolchain nightly &&\ 24 | cargo +nightly install --git https://github.com/alexcrichton/wasm-gc --force 25 | 26 | ENV CARGO_TARGET_ARMV7_UNKNOWN_LINUX_GNUEABIHF_LINKER arm-linux-gnueabihf-gcc 27 | ENV PKG_CONFIG_ALLOW_CROSS 1 28 | ENV PKG_CONFIG_PATH /usr/lib/arm-linux-gnueabihf/pkgconfig/ 29 | 30 | RUN useradd rust --user-group --create-home --shell /bin/bash --groups sudo 31 | WORKDIR /home/rust/src 32 | -------------------------------------------------------------------------------- /rpi/README.md: -------------------------------------------------------------------------------- 1 | # Cross-Compile for Raspberry Pi 2 | 3 | The Dockerfile and build script in this directory can be used to create an executable that will run on a [Raspberry Pi](https://www.raspberrypi.org).

To build the executable, run `make pi-build` in the project root and copy `substrate-evm` from the `./target/armv7-unknown-linux-gnueabihf/release` directory to the Raspberry Pi.
