Why WeiBlocks for Austin, TX
Solidity + Rust Under One Team
Most teams specialize in one. We deliver across EVM and Solana from the same engineering org — useful for multi-chain projects.
Audit-Ready Code
Internal code reviews + audit prep for major firms (OpenZeppelin, Trail of Bits, CertiK). Your audit doesn't get sent back with 'critical' findings.
Gas Optimization
Storage packing, calldata efficiency, custom errors, library usage — gas-tuned contracts that don't bleed money in production.
Real Production Track Record
Multi-chain crypto escrow platform (Escrowly), DeFi infrastructure (MBD Financials), AI Solana trading agent — production systems handling real money.
US-Based Compliance Lens
Securities classification, KYC/AML considerations, FinCEN — we surface compliance questions during design, not after deployment.

Frequently Asked Questions
Does WeiBlocks handle the third-party smart contract audit?
We prepare contracts for audit (internal review, test coverage, NatSpec documentation, formal property checks where applicable) and coordinate with audit firms (OpenZeppelin, Trail of Bits, CertiK, Halborn) on your behalf. The audit fee is paid to the audit firm directly.
Can you audit smart contracts written by someone else?
We do internal security reviews of third-party code — not formal audits (those are done by accredited firms). Our reviews catch ~80% of what a paid audit will find and run 1–2 weeks instead of 6+ weeks.
What test coverage do you target?
100% line and branch coverage on critical paths. Fuzz testing (Foundry, Echidna) for state machines. Formal verification (Certora) when economic risk justifies it.
What's the cost of a smart contract project in Austin?
Single contract + tests + audit prep: $8K–$25K. Multi-contract DeFi protocol: $50K–$200K. NFT marketplace contracts: $20K–$60K. Add'l for third-party audit fees (typically $20K–$100K paid to audit firm).
Which audit firms have you worked with?
We've prepared and coordinated audits with OpenZeppelin, Trail of Bits, CertiK, Halborn, and several Solana-specialist firms (Ottersec, Neodyme). We can recommend the right firm for your stack and timeline.
