Solidity Development
WAYF is a Solidity Development Agency:
Smart Contracts. Serious Stakes.
Smart contracts that handle real money. Built with the caution that responsibility requires.
Solidity development isn't like other software. Bugs aren't fixed with patches—they're exploited for millions. Deployed code can't be easily changed. The stakes are different, and so is our approach: conservative architecture, comprehensive testing, and an honest assessment of whether a smart contract is even the right solution.
What We Build
Smart contracts for Ethereum and EVM-compatible chains. Token contracts, governance systems, staking mechanisms, escrow logic. The on-chain components that power decentralized applications.
DeFi protocol components. Lending pools, automated market makers, yield strategies, cross-protocol integrations. We understand the composability of DeFi and the risks it introduces.
NFT infrastructure. Minting contracts, marketplace integrations, royalty mechanisms, on-chain metadata. Beyond basic ERC-721—custom logic that serves specific collection requirements.
DAO tooling. Voting mechanisms, treasury management, proposal systems. Governance that actually works, not just governance that looks good in a pitch deck.
Protocol integrations. Connecting your application to existing DeFi protocols, oracles, bridges. Working with the Ethereum ecosystem rather than rebuilding it.
What we build less of: speculative tokens with no utility, contracts designed primarily to extract value from users, or projects where the smart contract is a solution looking for a problem. We're selective. The reputation cost of participating in exploitative projects isn't worth the revenue.
Why Us
How We Work
Solidity projects require more upfront design than typical software. Changing deployed contracts is difficult or impossible. We invest heavily in specification, threat modeling, and architecture before writing production code.
Development follows a deliberate sequence: specification and threat modeling first. Test suites that encode expected behavior. Implementation against those tests. Internal review. Testnet deployment and verification. External audit coordination. Mainnet deployment with monitoring.
When we work with existing protocols, we start with a thorough assessment. Code review, architecture analysis, identification of risks and technical debt. Some protocols need optimization. Some need security improvements. Some need honest conversations about fundamental design choices. We provide clarity on which.
What makes Solidity projects different: the immutability. Traditional software can be patched; smart contracts often can't. Upgradability patterns exist but introduce their own complexity and trust assumptions. We design for the permanence that blockchain implies—or implement upgrade patterns when the tradeoffs make sense.
What stays constant: direct communication about risk. If we see a vulnerability, you hear about it immediately. If a design choice introduces systemic risk, we raise it—even if the timeline implications are uncomfortable.
Technical Approach
Security-First Development
Every contract gets threat modeling before implementation. We identify attack vectors, analyze economic incentives, consider composability risks. Test suites include not just happy paths but adversarial scenarios—reentrancy attempts, front-running, oracle manipulation, governance attacks.
Comprehensive Testing
Unit tests for individual functions. Integration tests for contract interactions. Fuzz testing for edge cases. Fork testing against mainnet state. Formal verification for critical invariants when the protocol justifies the investment. Test coverage isn't a vanity metric—it's confidence in behavior.
Multi-Chain Considerations
EVM equivalence isn't perfect. Gas costs differ, opcodes behave differently, ecosystem integrations vary. We test on target chains, not just mainnet forks, and account for the differences in deployment and monitoring.
Monitoring and Incident Response
On-chain monitoring for anomalous transactions. Alerting systems that catch exploits early. Runbooks for incident response—pause mechanisms, communication plans, recovery procedures. The security work doesn't end at deployment.
What We See Go Wrong
The most common pattern: treating smart contracts like web applications. Move fast, iterate in production, fix bugs with deploys. This mentality has cost protocols hundreds of millions of dollars. Smart contract development requires a different mindset—closer to aerospace engineering than web development.
We also see protocols skip audits or treat them as checkboxes. An audit from a reputable firm takes weeks, costs significant money, and often reveals issues that require substantial rework. Teams that budget neither the time nor the money end up with false confidence.
Another pattern: excessive complexity. Every line of Solidity is attack surface. Gas optimization that obscures logic, clever patterns that auditors struggle to verify, architecture that's sophisticated beyond what the problem requires. Simple contracts with clear logic are easier to secure. We push for simplicity.
We also see teams misunderstand upgradability. Proxy patterns solve the immutability problem but introduce trust assumptions—whoever controls the upgrade key controls the protocol. For some applications, that tradeoff is fine. For "decentralized" protocols, it undermines the entire value proposition. We help teams think through these implications.
We're not here to criticize how protocols got where they are. Market pressure, limited budgets, and genuine uncertainty all contribute. We assess what exists, identify the risks, and figure out the safest path forward.
Who We Work Well With
Teams building protocols where decentralization matters—not as a buzzword but as a genuine design requirement. Applications where trustlessness, censorship resistance, or permissionless access provide real value.
Also: established protocols that need security improvements, gas optimization, or feature development from engineers who understand the stakes. And traditional companies exploring blockchain for legitimate use cases—supply chain verification, credential systems, settlement layers—where the technology fits the problem.
What all share: understanding that smart contract development is slower and more expensive than traditional development, and accepting that tradeoff because the security requirements justify it.
Who We're Not For
If you want smart contracts developed quickly and cheaply, without the testing and review that security requires, we're not a fit. The cost of doing this work properly is less than the cost of an exploit. Every time.
If your project is designed to extract value from users—whether through economic manipulation, deceptive tokenomics, or pump-and-dump mechanics—we won't participate. The Web3 space has enough bad actors; we don't contribute to the problem.
If you're adding blockchain because it sounds innovative, without a clear answer to "why does this need to be on-chain?"—we'll have that conversation first. Sometimes the answer clarifies a genuine use case. Sometimes it reveals that traditional architecture would serve you better. Either outcome is useful.
