Frequently Asked Questions
Get clear answers on our development process, timelines, and security for your batch minting bridge.
A standard cross-chain NFT batch minting bridge with support for 2-3 EVM chains typically deploys in 3-5 weeks. This includes smart contract development, integration with our bridge relayers, front-end dashboard, and security audit. Complex requirements like custom minting logic or support for non-EVM chains (e.g., Solana) can extend the timeline, which we scope and quote for upfront.
