Fill City

Fill City was a decentralized spot exchange built on Solana, branded as "The Ultimate Solana Spot Exchange" and pitched at sophisticated traders looking for a purpose-built trading venue on Solana. The platform also maintained a parallel deployment on Eclipse, a Solana Virtual Machine (SVM) Layer 2 network, accessible at eclipse.fill.city.

What It Was

Fill City positioned itself as a dedicated spot trading destination on Solana, distinct in emphasis from general-purpose DEX aggregators. The platform maintained token-specific trading pages — for example, a dedicated page for SOL and a /markets route listing available trading pairs — suggesting it supported multiple SPL tokens across Solana's ecosystem. The tagline "where sophisticated traders go to trade on Solana" indicated it was aimed at active traders rather than casual swappers.

Its presence on Eclipse as well as Solana mainnet suggested the team was expanding to SVM-compatible chains beyond Solana L1, a pattern common to Solana-native DeFi projects during 2024–2025.

Domain Registration and Timeline

Fill City's domain, fill.city, was registered on January 7, 2024, placing its likely launch in early 2024. The Wayback Machine recorded 354 indexed pages across 26 crawls, indicating the platform had meaningful content depth when active. The most recent Wayback Machine snapshot is dated August 12, 2025.

As of mid-2026, fill.city redirects to an expired domain resale listing and is offered for purchase at $100 USD via GoDaddy. All associated subdomains — including eclipse.fill.city and docs.fill.city — are NXDOMAIN. No shutdown announcement has been located. The platform appears to have quietly ceased operations sometime after August 2025 when its domain was last captured by the Wayback Machine.

Social Media and Team

Fill City left no active social media footprint in available records. Its Compass project entry lists no Twitter, Discord, Reddit, or GitHub links. Independent media coverage of the platform is absent from Solana DEX roundups published in 2025 or 2026. No security audits, team disclosures, or investor announcements have been located through web searches.

Current Status

Fill City is no longer accessible. The expired domain, NXDOMAIN subdomains, and absence from DeFi tracking services (DefiLlama, DexScreener, CoinGecko) all confirm the platform is inactive. Anyone encountering references to fill.city should treat the project as defunct.
