Smart Contracts
Solidity / EVM
Development and integration of smart contracts on Solidity for Ethereum and compatible networks: Base, Arbitrum, Polygon, BNB Chain and other EVM ecosystems.
- Solidity
- The main language for developing and formalizing on-chain logic
- 5+ networks
- Unified codebase for interoperable EVM ecosystems
- ERC-20/721/1155
- Token, NFT and Multi-Asset Standards
Are you facing these issues?
Reentrancy, Access Errors, and Permanent Asset Loss
One incorrect role check or external call before the state is updated allows you to withdraw funds again or take control of the contract.
Solution
We use checks-effects-interactions, OpenZeppelin access control, pull payments, pausable mechanics and test negative scenarios in Foundry.
High gas and dangerous proxy contract updates
Inefficient storage increases transaction costs, and changing the layout during upgrade can damage the state of an already running protocol.
Solution
We optimize storage and calldata, fix the upgrade policy, check the storage layout and protect updates with multisig and timelock control.
