# Technology & Operations ### Mosaic Chain (Substrate base, parachain) Mosaic Chain is built on Substrate and can operate as a parachain in the Polkadot family. Substrate modules handle balances, vesting, and governance; cross-chain features enable future interoperability. Supporting EVM-compatible smart contracts widens developer and wallet support. ### Smart Contracts Sales run through audited contracts that escrow contributions, enforce caps and timelines, and trigger refunds if conditions (like soft caps) are not met. Vesting contracts release tokens over time; the claim interface calls these contracts and shows your remaining schedule. All state changes are visible on block explorers. ### Wallet & Network Support Investors can connect common EVM wallets or supported Substrate wallets depending on the sale. The UI prompts you to switch networks, shows gas estimates, and links to the explorer so you can verify each step. Keep native gas tokens handy and always confirm you are on the correct network before signing. ### Security & Audits Issuer fundraising contracts must be audited before listing. Mosaic performs routine internal reviews of platform components and partners with external auditors as needed. Keys used for administrative actions (where any exist) are protected by multi-party controls. Incident reporting and hotfix procedures are documented; critical changes are announced and, when feasible, gated by governance. ### Why this matters Operational clarity reduces avoidable errors. Audited contracts and transparent explorers make it easier to trust what you can verify. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
