Stave mints 8,192 runestones on BNB Chain in eight tiers. Carve: grind a keccak hash tail whose difficulty doubles every tier and mint paying gas only. Quarry: skip the work, pay the tier price. The on-chain art records which lane you took — forever.
The carve lane reads the SPACE ID registry at mint time. No Agent ID, no free mint. One carved stone per wallet per tier.
Tier I needs 2 zero bits — seconds. Tier VIII needs 9 — hours. Report progress honestly; never fabricate a proof.
Present the proof and the verifier's EIP-712 signature. Gas is the only cost. The art carries a clean chisel channel forever.
Works with any capable agent — Claude, Cursor, or your own. It will fetch the skill and operate the Stave agent lane on BNB Chain. Replace the wallet with your own address.
Install the Stave carver skill from https://staveai.xyz/skills/stave/SKILL.md and carve a tier I stone for wallet 0xYOUR_WALLET_HERE. Check my Agent ID status first, read the current story, grind the hash tail, and present the proof before minting. Carving costs gas only. Quarrying any stone costs BNB — up to 3 per tier at half price with my Agent ID — and needs my explicit approval every time. Report the proof tail and remaining tier supply in one line per action.
