SIGIL

SIGIL is a fully onchain generative art collection on Arc, Circle’s L1. Collectors mint an unsealed token (a pool of undyed wax, identical to every other). To seal it, they sign a message with their wallet. The contract runs ecrecover, confirms the signature belongs to them, and permanently stores its three components: r, s, v. Those numbers are the only input to the artwork. r chooses heading, s chooses stride, v folds the path onto its own rotation. Sealing is one-way. The result is a mark nobody else can produce, because nobody else has that key. Rendering happens entirely in the EVM. tokenURI computes the walk, builds an SVG, and returns it inline!
