FAQ

Common questions

Do you work with both Solana and EVM chains?

Yes. We have deep expertise in both ecosystems—Anchor/Rust for Solana and Solidity/Hardhat/Foundry for EVM chains. We can also architect cross-chain solutions.

Do you provide security audits?

We perform comprehensive internal security reviews and hardening. For formal audits, we coordinate with trusted audit partners and manage the remediation process.

Can you integrate with existing systems?

Absolutely. We regularly integrate with existing backends, databases, analytics platforms, and payment rails. Our APIs are designed for interoperability.

What does a typical token launch include?

Token contract, vesting/claim logic, claim portal UI, liquidity provision scripts, anti-bot protection, admin dashboard, and full monitoring setup.

How do you handle post-launch support?

We provide runbooks, monitoring dashboards, and a support period. Retainer options are available for ongoing maintenance and feature development.
