THE LOST PIXEL GEM

What it is — a one-way migration. You burn your OLD gem (an ERC-721 whose art lives off-chain on IPFS) and mint the same token # as a brand-new PIXELGEMS — an ERC-721 whose art is stored 100% on-chain and stays re-editable forever. You also receive PIXELS pool rewards (flat, once per wallet).

The contracts (Ethereum mainnet)

• OLD — burned: THE LOST PIXEL GEM · standard ERC-721, art on IPFS.
• PIXELGEMS — minted: on-chain collection · 100% on-chain SVG, re-editable.
• POOLGEMS — the controller: burn/claim contract · burns your OLD, mints the NEW & pays the reward — atomically, in one tx.

How you interact — 3 steps

1. Connect your wallet — non-custodial: your gems never leave your wallet until they burn in the tx you sign.
2. Select the OLD gems you own — ownership is verified on-chain.
3. Burn & claim — approve once, then sign one atomic transaction per batch: it burns your OLD, mints your PIXELGEMS (same id) and pays the pool reward. You only pay gas.

Security — each claim is authorized by a platform EIP-712 signature (dedicated backend signer, enforced by the contract) and a per-wallet nonce; the burn + mint is a single transaction you sign. Nothing is custodial, and the migration is permanent.
