Openfort Contracts

Official Contracts of the Openfort Project.

The following standards are supported:

• ERC-20, ERC-721, ERC-777 and ERC-1155 for different token handling.
• ERC-173 for ownership standard.
• EIP-712 and EIP-5267 for typed structured data hashing and signing.
• ERC-1271 for standard signature validation.
• ERC-1967 and ERC-1822 for proxies (upgradeable Openfort accounts).
• EIP-1014 for generating counterfactual addresses using Openfort factories.
• ERC-4337 for leveraging Account Abstraction using alternative mempools.
• ERC-6551 for leveraging Token Bound Accounts

Development

Install Foundry

  curl -L https://foundry.paradigm.xyz | bash
  foundryup

Build and test

  git clone https://github.com/openfort-xyz/openfort-contracts.git && cd openfort-contracts
  yarn
  forge install
  forge build
  forge test

Unit Test Coverage

You can use Foundry to get the unit test coverage. Use the lcov report format and genhtml to view the coverage data in a nice web interface.

  forge coverage --report lcov
  genhtml -o report --branch-coverage lcov.info

Use different built-in scripts

Before executing any of the scripts below, make sure you've properly configured your .env file.

Generate a gas report

./script/gasProfile.sh

Deploy Upgradeable and Managed factories to all chains

./script/deployAllChains.sh

Check paymaster's deposit and Patron's balance on different chains

forge script CheckDeposits --force

Deploy one upgradeable factory and one account

Simulation:

forge script --force script/deployManagedAccounts.s.sol -vvvvv --optimizer-runs 1000000 --slow --fork-url $<rpc_network>

Actual deployment:

forge script --force script/deployManagedAccounts.s.sol  -vvvvv --optimizer-runs 1000000 --slow --fork-url $<rpc_network> --broadcast --verify --etherscan-api-key $<api_key>

Compare gas costs

You can compare gas costs by running the following command against different gas reports:

forge snapshot --silent --diff gas_reports/2023-05-24_11:52.snap.out

Static Analyzers

Static analysis using Slither

If you want to perform a static analysis of the smart contracts using Slither, you can run the following commands:

  pip3 install slither-analyzer
  pip3 install solc-select
  solc-select install 0.8.19
  solc-select use 0.8.19
  slither .

Static analysis using Mythril

If you want to perform a static analysis of the smart contracts using Mythril, you can run the following commands:

  rustup default nightly
  pip3 install mythril
  myth analyze contracts/core/static/StaticOpenfortAccount.sol --solc-json mythril.config.json

If you run into the error ImportError: cannot import name 'getargspec' from 'inspect' from Python3 running the commands above, please see the temporary fix on this comment.

Gas Stats

There are two different categories of benchmarks measured in this test: User Operation and Runtime.

• User Operation: Fees are calculated based on the transaction receipt and the serialized signed EIP-1559 transaction for entryPoint.handleUserOp([userOp]). As multi-user-op bundles become more prevalent, we can expect actual fees to undercut the data presented here.
• Runtime: Runtime transactions are defined as those performed outside of the user operation flow, with the owner key interacting directly with the account factory or account, akin to the way you might use MetaMask today to interact directly with smart contracts.

Gas Stats in USD

As of April 2024, the gas price range is reported as the daily average gas price for the first 90 days of 2023 ± one standard deviation.
