Herein is an experimental custom vm that, assuming, a stablecoin as the native gas token attempts to aim for a $0.01 transfer fee for most accounts and $0.10 for new accounts.
Fees are accumulated to the validators instead of being burned
Three new config properties have been added:
-
defaultFeeRecipient Added this config to prevent the burning gas tokens at the subnet level. Typically, one would first set
allowFeeRecipients=truein the subnet config; however if a validator mistakenly does not include afeeRecipientin their chain config (unique to their node), the default behavior would have been to burn the gas value for any blocks produced by that validator. -
nonceThresholdForNewAccounts If set, any account with a nonce less than this value is considered a new account for the purposes of transfer fees (see below)
-
gasMultiplierForNewAccounts New accounts, as defined above, have their gas usage multiplied by this factor. This allows you to, for example, set a target transfer fee of X for new accounts and X/10 for established accounts, as defined by their nonce.
You can check out the config used in scripts/run.sh
In addition to the above new properties, the config uses 2 stateful precompiles: contractDeployerAllowListConfig and contractNativeMinterConfig
In this example:
- Only the BRIDGE user can deploy new contracts. Uses an EOA as the bridge user for simplicity.
- The BRIDGE user can mint native tokens
- Gas costs are set such that established users can make transfers at a cost of $0.01/tx (assuming the native token is a stablecoin)
- New users pay 10x ($0.10/tx) for spam prevention
- Gas fees are meant to accumulate to the validators instead of being burned. We add an extra safety net in case the validator erroneously does not include a
feeRecipientin their chain config by adding a newdefaultFeeRecipientproperty at the subnet level - Disallows custom contract creation; but we modify the vm to permit contract creations from allowlisted contracts even if user (tx.origin) does not have deploy permissions
The examples below use cast
First create 3 new addresses with cast wallet new and then run a local network with the subnet:
## only the bridge account will be able to
## (1) mint new native tokens, (2) deploy new contracts
export BRIDGE=<0x...>
export FEE_RECV=<0x...>
export SOME_USER=<0x...>
export BRIDGE_KEY=<KEY_FOR_BRIDGE>
./scripts/run.sh 1.7.13 $BRIDGE $FEE_RECV
export ETH_RPC_URL=<ADDRESS_PRINTED_OUT_BY_ABOVE>
$ cast balance $BRIDGE | cast --from-wei
100
$ cast balance $FEE_RECV | cast --from-wei
0
$ cast balance $SOME_USER | cast --from-wei
0
## send 10 transactions from BRIDGE -> SOME_USER
$ for i in $(seq 0 9); do cast send --private-key $BRIDGE_KEY $SOME_USER --value 1ether --cast-async --nonce $i; done
## First 5 transactions should have a gas usage of 210,000 (since we used a multiplier of 10x)
## Next 5 transactions should have a gas usage of 21,000 (since the nonce threshold for new accounts was set to 5)
## Total fees accumulated this point should be a less than $0.55
$ cast balance $FEE_RECV | cast --from-wei
0.523215000000000000
## User should have received $10
$ cast balance $SOME_USER | cast --from-wei
10.000000000000000000
## Let's try out native token minting
## Confirm BRIDGE is on the allowlist
$ cast call 0x0200000000000000000000000000000000000001 'readAllowList(address)(uint256)' $BRIDGE
2
## And, mint $5...
$ cast send --private-key $BRIDGE_KEY 0x0200000000000000000000000000000000000001 'mintNativeCoin(address, uint256)' $SOME_USER $(cast to-wei 5)
$ cast balance $SOME_USER | cast --from-wei
15.000000000000000000
Allow users to deploy (only) from allowlisted contract factories:
## using safe-contracts (https://github.com/safe-global/safe-contracts) (details left to the reader)
## deploy Gnosis Safe on this new subnet
$ NODE_URL=$ETH_RPC_URL PK=$BRIDGE_KEY CUSTOM_DETERMINISTIC_DEPLOYMENT="true" yarn hardhat --network custom deploy
factory: 0x5ec817e60bb24161d098Da64F711d734c1991a93
GnosisSafe singleton: 0x5ec817e60bb24161d098Da64F711d734c1991a93
## enable GnosisSafe factory to create contracts on behalf of users
$ cast send --private-key $BRIDGE_KEY 0x0200000000000000000000000000000000000000 'setEnabled(address)' "0x5ec817e60bb24161d098Da64F711d734c1991a93"
## confirm
$ cast call 0x0200000000000000000000000000000000000000 "readAllowList(address)(uint256)" "0x5ec817e60bb24161d098Da64F711d734c1991a93"
1
## Now users who do not normally have permission to deploy custom contracts can still
## deploy contracts via an allowlisted contract factory (in this example, Gnosis Safe proxies)
## using safe-tasks (https://github.com/5afe/safe-tasks)
$ NETWORK=custom NODE_URL=$ETH_RPC_URL PK=$USER_PKK yarn safe create --factory 0x5ec817e60bb24161d098Da64F711d734c1991a93 --singleton 0xc5539e0e5579A85D6A5c51eF722DA54190f7Ad6B
This changes in this fork are experimental and not meant for production use. It's just for fun!
Avalanche is a network composed of multiple blockchains. Each blockchain is an instance of a Virtual Machine (VM), much like an object in an object-oriented language is an instance of a class. That is, the VM defines the behavior of the blockchain.
Subnet EVM is the Virtual Machine (VM) that defines the Subnet Contract Chains. Subnet EVM is a simplified version of Coreth VM (C-Chain).
This chain implements the Ethereum Virtual Machine and supports Solidity smart contracts as well as most other Ethereum client functionality.
The Subnet EVM runs in a separate process from the main AvalancheGo process and communicates with it over a local gRPC connection.
[v0.1.0] AvalancheGo@v1.7.0-v1.7.4
[v0.1.1-v0.1.2] AvalancheGo@v1.7.5-v1.7.6
[v0.2.0] AvalancheGo@v1.7.7-v1.7.9
[v0.2.1] AvalancheGo@v1.7.10
[v0.2.2] AvalancheGo@v1.7.11-v1.7.12
[v0.2.3] AvalancheGo@v1.7.13-v1.7.14
[v0.2.4] AvalancheGo@v1.7.13-v1.7.14
[v0.2.5] AvalancheGo@v1.7.13-v1.7.14
The Subnet EVM supports the following API namespaces:
ethpersonaltxpooldebug
Only the eth namespace is enabled by default.
Full documentation for the C-Chain's API can be found here.
The Subnet EVM is compatible with almost all Ethereum tooling, including Remix, Metamask and Truffle.
- Added configurable fees and gas limits in genesis
- Merged Avalanche hardforks into the single "Subnet EVM" hardfork
- Removed Atomic Txs and Shared Memory
- Removed Multicoin Contract and State
To support these changes, there have been a number of changes to the SubnetEVM block format compared to what exists on the C-Chain and Ethereum. Here we list the changes to the block format as compared to Ethereum.
BaseFee: Added by EIP-1559 to represent the base fee of the block (present in Ethereum as of EIP-1559)BlockGasCost: surcharge for producing a block faster than the target rate
First install Go 1.17.9 or later, however as the time of writing, please don't use Go v1.18.x versions. Follow the instructions here. You can verify by runing go version.
Set $GOPATH environment variable properly for Go to look for Go Workspaces. Please read this for details. You can verify by running echo $GOPATH.
As a few software will be installed into $GOPATH/bin, please make sure that $GOPATH/bin is in your $PATH, otherwise, you may get error running the commands below.
Download the subnet-evm repository into your $GOPATH:
cd $GOPATH
mkdir -p src/github.com/ava-labs
cd src/github.com/ava-labs
git clone git@github.com:ava-labs/subnet-evm.git
cd subnet-evmThis will clone and checkout to master branch.
scripts/run.sh automatically installs avalanchego, sets up a local network,
and creates a subnet-evm genesis file. The usage of this script is
./scripts/run.sh [AVALANCHEGO VERSION] [GENESIS_ADDRESS]# to startup a local cluster (good for development)
cd ${HOME}/go/src/github.com/ava-labs/subnet-evm
git pull
./scripts/run.sh 1.7.13 0x8db97C7cEcE249c2b98bDC0226Cc4C2A57BF52FCNote: make sure you check the version compatibility above between AvalancheGo and Subnet-evm and use the proper version of AvalancheGo.

You can create a new metamask account by importing the private key 0x56289e99c94b6912bfc12adc093c9b51124f0dc54ac7a766b2bc5ccf558d8027 and start experiencing with this account.
When building developing your own blockchain using subnet-evm, you may want
to analyze how your fee paramterization behaves and/or how many resources your VM
uses under different load patterns. For this reason, we developed cmd/simulator.
cmd/simulator lets your drive arbitrary load across any number of [endpoints]
with a user-specified concurrency, base-fee, and priority-fee.
To get started, open the directory cmd/simulator and add your network's endpoints to
the file at .simulator/config.yml (these will be provided after running
./scripts/run.sh. With the example above, the correct endpoints is http://127.0.0.1:14463/ext/bc/28N1Tv5CZziQ3FKCaXmo8xtxoFtuoVA6NvZykAT5MtGjF4JkGs/rpc to replace http://localhost:9650/ext/bc/my-chain/rpc.):
endpoints:
- http://localhost:9650/ext/bc/my-chain/rpc
base-fee: 25
priority-fee: 1
concurrency: 10Once your config is specified, you can run the tool by either invoking go run main.go under the directory cmd/simulator or by installing the tool (go install -v .) and running the binary
(simulator).
To make getting started easier, the ewoq key 0x8db97C7cEcE249c2b98bDC0226Cc4C2A57BF52FC
has been pre-added to the simulator key directory and can be added to genesis during local network
creation (./scripts/run.sh [AVALANCHEGO VERSION] 0x8db97C7cEcE249c2b98bDC0226Cc4C2A57BF52FC).
If you do not add this key to genesis, you'll need to manually fund the
master account when prompted in the terminal.
The private key for the ewoq address (0x8db97C7cEcE249c2b98bDC0226Cc4C2A57BF52FC) is
0x56289e99c94b6912bfc12adc093c9b51124f0dc54ac7a766b2bc5ccf558d8027.

The WAGMI ("We're All Going to Make It") Subnet Demo is a high throughput
testbed for EVM (Ethereum Virtual Machine) optimizations. It is parameterized
to run at a factor more capacity than Fuji/Mainnet C-Chain and will be used
to experiment with release candidates before they make it into an
official coreth release.
We created a basic WAGMI explorer that surfaces aggregated usage statistics about the subnet. If you'd like to see any other stats added to this site, please send a DM to @_patrickogrady on Twitter.
Everyone that has used the the C-Chain more than twice (~970k addresses) has been airdropped 10 WGM tokens. With the current fee parameterization, this should be enough for hundreds of txs.
This is one of the first cases of using Avalanche Subnets as a proving ground for changes in a production VM (coreth). Many underestimate how useful the isolation of subnets is for performing complex VM testing on a live network (without impacting the stability of the primary network).
To create WAGMI, all we had to do was run the following command:
subnet-cli wizard \
--node-ids=NodeID-9TCq8np31pHjjhGaHtLjs6ptYYPEt3LGb,NodeID-BrYXghQSu6KKGjuzhs3nrkcB46Wc2yYHy,NodeID-89UCR1CsPzzEHuknxhJHKxuFPNCyPz7Bu,NodeID-Hfm8gpD4DpCz4KTzt2osJPfFvu7az3qiD,NodeID-LkdxkfYhg6nSw1EEUxDUSYPXPwmr2cUet \
--vm-genesis-path=networks/11111/genesis.json \
--vm-id=srEXiWaHuhNyGwPUi444Tu47ZEDwxTWrbQiuD7FmgSAQ6X7Dy \
--chain-name=wagmiThis added these NodeIDs as validators on Fuji, created the WAGMI Subnet, added all validators to the WAGMI subnet, and created the WAGMI chain.
