Finance Smart Contract Domain Naming

I’m building a blockchain-based platform focused on smart contracts for the finance sector and need a memorable, brand-ready domain name that is still available for registration. I’d like you to research and present a concise shortlist of options—ideally .com or other widely recognised extensions—keeping regulatory and credibility concerns that are unique to financial services in mind.

To be considered, tell me about any similar naming or branding projects you’ve handled in the blockchain or fintech space and how you verified domain availability for those clients. I’m interested in your direct experience more than lengthy proposals.

Deliverable: a brief report with several viable domain names (confirmed as available at time of delivery) along with a one-sentence rationale for each choice.
