As of April 30, 2025 the firm was acquired by and rebranded as Arca; blocktower.com now 301-redirects to ar.ca and BlockTower no longer operates as a standalone brand. The firm published no public API, developer portal, or SDK surface, so there is no API artifact set to enrich here beyond identity and a domain-security probe of the still-resolving legacy domain. url: https://raw.githubusercontent.com/api-evangelist/blocktower-capital/refs/heads/main/apis.yml x-type: company x-source: vc-portfolio x-backed-by: - a16z - union-square-ventures x-tier: stub x-tier-reason: portfolio-lead x-status: acquired x-successor: arca x-successor-url: https://www.ar.ca x-acquired-date: '2025-04-30' x-has-api: false specificationVersion: '0.20' created: '2026-07-17' modified: '2026-07-18' tags: - Company - Cryptocurrency - Digital Assets - Investment Management - Blockchain - Venture Capital - Hedge Fund - Acquired apis: [] maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io common: - type: DomainSecurity url: security/blocktower-capital-domain-security.yml - type: Website url: https://blocktower.com x-enrichment: date: '2026-07-19' status: backfilled pass: local-v1 note: backfilled from .gitignore signal + verified work evidence
