Vangrid treats physical capture as an on-chain service agents can buy directly. @vangrid_io A bounty specifies a site, budget, and deadline; a person films an orbit or walk-through; the platform reconstructs the 3D model and releases escrow on acceptance. Platform fee and reconstruction cost are deducted before the contributor is paid, with full refunds on cancel or expiry. Arc’s deterministic finality keeps the payment leg under a second, matching the chain’s design for agent-run businesses. Coverage so far includes streets, docks, interiors, and other operational spaces. The model is simple: agents request ground truth, humans supply it, and the chain settles the exchange. The grid expands one accepted capture at a time.
