The ElastiVaultFactory was created to deploy instances of the OwnableElastiVault, ECDSAElastiVault, and ECDSAMultisigElastiVault.

This repository includes contracts related to the ElastiVault, an infinitely elastic smart contract wallet. What this means, is that you can execute any on-chain action without needing to deploy predefined logic smart contracts.

Think of it this way; your current web3 UX can be quite cumbersome. Often many of your actions need to be executed in separate transactions, or if you want to perform some grouped-actions a smart contract would need to be deployed and then called.

Each implementation of the ElastiVault offers a solution to this problem by allowing the user to execute arbitrary bytecode from the context of the wallet-vault. Basically, the vault allows users to specify "scripts" to run on-chain.

Consider this example: If you want to perform some complicated arbitrage of some erc20 from one dex to another:

• approve dex1 to swap your token
• call dex1 to perform a token swap
• transfer the tokens
• approve dex2 to swap your token
• call dex2 to perform a token swap

This can be accomplished in 1 call to an ElastiVault, as the user can define a single script that performs ALL of these actions, executing it from their wallet-vault.

The ElastiVault allows for some pretty complicated use-cases, each in 1 transaction:

• execute multiple swaps
• interact with several protocols
• read complicated state from several on-chain sources, and use that state to conditionally perform an action (require statements etc. are fully supported)

These on-chain scripts written/used here are all written in Solidity, but any language that complies to EVM-bytecode should be possible here.

Example Usage

HardHat Scripts

# start hardhat node
hardhat node
# deploy the ElastiVault factory contract
hardhat run scripts/deployVaultFactory.ts # returns <VAULT_ADDR> ex: 0x106297B870019eBbcC51E84E350899da495cE803
# deploy an "owned" vault using a chosen ElastiVault factory
hardhat --network localhost factoryDeployVault <VAULT_ADDR> owned <CHOSEN_SIGNER(S)> # returns <VAULT_ADDR>
# call a basic script from the context of a chosen ElastiVault (that the caller owns)
hardhat --network localhost callOwnableElastiVault <VAULT_ADDR> CallTest --call

HardHat Tests

# start hardhat node
hardhat node
# run the tests against the local node
hardhat test --network localhost

Factory Contract Deployments:

The ElastiVaultFactory has been deployed to 0x00000000131889aD41211C79fc63860c9720D4de on the following networks:

• Ethereum
  • Mainnet
  • Goerli Testnet
  • Sepolia Testnet

Future Plans

• ZK ownership - Allow the use of Zero Knowledge proofs to verify ownership of a vault
• Support ERC-4337 Account Abstraction

Notes

• For maximum compatibility, if storing state (storage) in an ElastiVault we highly recommended using the Diamond storage pattern. This is not required, but helps to avoid storage collisions.
• The tests included here are intended to be run against a mainnet/testnet fork due to availability of external dependencies. Currently the tests are set to run against the Goerli Testnet.
• Also consult the HyVM repo in regards to memory layout, divergence, & EVM opcode compatibility.
• Each ElastiVault implementation is by-design able to execute arbitrary bytecode (scripts) on-chain, and this comes with its associated dangers. Users of these vaults should be careful to sign transactions/bytecode, just as with any web3 interaction. Special steps should be taken by the user to ensure they are only executing bytecode they are familiar with. We invite external parties to help build out tooling that will make this safer for users.
