Install

Clone https://github.com/to-nexus/skill-cross-nft into a temporary directory and run the install.sh script inside it to install the skill-cross-nft skill into my Claude Code environment. Tell me the result in one line when you're done.
  1. For personal testing, keep local signer config in the skill .env before marketplace writes.
  2. For team, hosted-agent, or production funds, prefer Vault/KMS/HSM-backed signing.
  3. Listings and accept-offer trigger setApprovalForAll automatically.

Heads-up: CROSS NFT runs on local agent runtimes only — see the Where it runs section for the supported list. Hosted chat environments cannot execute this skill.

Safety & credentials

This skill signs on-chain transactions

  • 🔴 Signs on-chain transactions — local signer config required.
  • Auto-approvals: setApprovalForAll(MarketplaceV1, true) — on listing / accept-offer.
  • approve(payment_token, MarketplaceV1, amount) — on buy.

Troubleshooting

›listing_not_active?
Already sold or canceled. Verify with listing <id>.
›Listing not visible after create?
GraphQL indexing lag of 5–15s.
›Offer acceptance failed?
The offerer's ERC-20 balance or approval may be insufficient.
