Blockchain & Web3 Engineering
BuildersLabs designs and builds the onchain part of your product. The work starts at the architecture and continues to the tests, the audit preparation, and the integration with your application.
Protocol and contract architecture
The architecture decides what you can change later and what you cannot. BuildersLabs writes it down before the first line of Solidity.
- Protocol design for tokens, NFTs, smart accounts, and custom logic
- Storage layout, upgrade paths, and access control
- Standard selection: ERC, LSP, and the trade-offs of each one
- Gas and risk analysis on the parts that carry value
Implementation and test strategy
A contract is correct when the tests prove it. BuildersLabs delivers the implementation together with the tests that defend it.
- Solidity implementation with Foundry or Hardhat
- Unit, integration, and mainnet fork tests
- Fuzz and invariant tests on the economic logic
- Deployment scripts, verification, and release steps
Review, audit preparation, and DeFi systems
An audit is cheaper when the code is ready for it. Each finding comes with example code, so your team learns from the review.
- Code review before an external audit
- Answers and fixes during the audit itself
- Integration with DeFi lending markets and automated market makers. Examples include Aave, Morpho, and Uniswap.
- Integration with liquid staking tokens (LSTs)
- Cross-chain bridges, wrappers, and message flows
Examples of protocol and product work
These are examples of the systems that BuildersLabs can design and implement.
NFT collection & minting
Minting logic, metadata flows, and upgrade-safe architecture for collectible or utility NFT systems.
Auction sale contract
Reliable settlement logic, bidding flows, and access control for onchain sales.
DAO governance system
Permissions, proposal flows, and execution paths for decentralized governance.
Liquid staking token
Staking derivatives, share accounting, and protocol integrations for LST products.
DeFi vault application
Vaults, adapters, hooks, and automation layers for composable DeFi products.
Storage-heavy protocol contracts
Complex onchain storage layouts and protocol logic for data-heavy systems.
Cross-chain bridges & wrappers
Hyperlane integrations, token wrappers, and message flows across chains.
Wallet policy & upgrade architecture
Policy enforcement, proxy patterns, and upgrade-safe smart account systems.
