This is the repository for the core Morpher smart contract components of https://morpher.com
Morpher Smart Contracts are a collection of solidity files for on chain transactions and trustless state recovery from sidechain. 😳
Morpher rebuilds financial markets from the ground up on the Ethereum Blockchain. All in the pursuit of the perfect trading experience.
The Non-Proxy versions of Morpher Smart Contracts are fully and regularly audited. 🙌

There are two versions of the smart contracts:
Initially MorpherProtocol was written in a non-proxy way using Solidity 0.5 and the Eternal Storage Pattern.
Contracts are residing on the nonproxy-master Branch.
Updates are barely possible, that's also why the deployments are not managed through truffle artifacts. Addresses are stored in addressesAndRoles.json.
Q1/2022 the Contracts were updated to support the following things:
-
Proxied through transparent proxies for updating the contract logic
- No more Eternal Storage Pattern.
- Contract storage is now used directly.
- Lowered Gas costs and made maintenance easier
- MorpherState now holds only a Pointer to the Contracts in the Ecosystem, instead of the Storage.
-
Advanced Roles and Access Lists instead of a simple Ownable
- Allows for more fine-grained access control
- State having Administrators and Owner roles are not managed through OpenZeppelin Access Control
-
Usage of Foundry over Truffle for Unit-Testing
- Usage for Foundry over Truffle for Tests
- Still maintain the migration functionality from Truffle
- Run Truffle and Foundry in Parallel
The Proxied Contracts can be found in the proxy-master Branch.
For proxied contracts the build-artifacts are stored in the branch, they are not deleted. There is a helper function called printAddresses in the helpers directory.
- Switch over to the proxied-contracts branch
- Connect Truffle to MetaMask:
truffle dashboard - Select the right network from MetaMask (e.g. Polygon)
- Run
truffle exec ./helpers/printAddresses.js --network dashboard
At the time of writing, these are the addresses for Morpher Sidechain (Chain-ID 21), Mainnet (Chain-ID 1) and Polygon (Chain-ID 137):
