live archiveBase · Farcaster · NFT indexing
WarpletScan
A free, real-time, searchable archive of Warplet NFT mints on Base, enriched with Farcaster profiles and transaction evidence.
WarpletScan tracks every indexed mint, resolves social identity, serves NFT media through resilient gateways, and links each record back to Basescan and OpenSea. The original mint closed in 2025. The public archive remains useful.

02 / CURRENT PORTFOLIO

03 / INFRASTRUCTURE LAYERS
The chain is not the product.
It is one layer.
Arca uses onchain systems where public identity, settlement, ownership, and composability actually improve the product. Ordinary infrastructure stays ordinary.
- Identity
- ERC-8004 registrations and verifiable metadata across EVM networks and Solana.
- Payments
- x402, EIP-3009, USDC, Solana Pay, and wallet-native checkout experiments.
- Social
- Farcaster clients, mini apps, profile enrichment, casts, signers, and portable identity.
- Data
- NFT indexing, RPC access, contract reads, media resolution, and public explorer links.
- Operations
- Node preflight, diagnostics, safe repair, sanitized reports, and source-backed support.
04 / FIELD HISTORY
Before the company,
there was the work.
Arca Computer was incorporated in 2026. The founder’s web3 practice started years earlier in art, virtual worlds, communities, and onchain social systems.
- 2021–2023
Art entered the chain
Analogue ink work minted across Tezos, Polygon, and Ethereum, alongside community and gallery work in Cryptovoxels and Monaverse.
- 2022–2024
Platforms and communities
Product, community, and creator work across Versum, Voxels, and Screensaver sharpened the operating view: culture is infrastructure too.
- 2024–2025
Farcaster-native products
Mini apps, bots, social experiments, wallet-aware games, and WarpletScan turned protocol participation into shipped software.
- 2026–
Onchain systems for agents
Arca now builds identity, payments, data access, node operations, consumer worlds, and developer tooling as one evidence-led portfolio.
05 / PUBLIC EVIDENCE
Software should leave receipts.
Live products, source repositories, contracts, transaction explorers, package manifests, and contribution records. Claims stay attached to something another person can inspect.
SANTIAGO / OPEN CHANNEL
Build with the products.
Inspect the boundary.
Arca Computer builds products, developer infrastructure, and public tools. Onchain when useful. Evidence by default.
