Solana

• Solana is a leg like any other: the manifest carries a synthetic chain id (501 mainnet, 5010 devnet), and the crossr_launchpad program runs the same curve in SOL with the same fees and snipe tax. It hashes the manifest exactly like the EVM contracts, so the launch id is shared; the mint is a PDA of that id, the CREATE3 equivalent.
• Solana legs are not relayed through LayerZero. The creator opens them directly: an Ethereum creator signs a short message binding a Solana wallet as the fee recipient (verified on chain with secp256k1), a Solana-only creator launches with an address derived from their public key. The launch form does this right after the home-chain transaction; a missing leg can be created later from the token page.
• Tokens are Token-2022 mints with 9 decimals and on-chain metadata. Fees go straight to the creator and treasury wallets on every trade, so there is nothing to claim. Graduation happens inside the crossing buy into a constant-product pool held by the program forever; swap trades against it with a 1% fee plus the creator tax on the SOL side.
• Pair with stocks on Solana: any SPL / Token-2022 mint such as the xStocks (TSLAx, SPYx, …) can be a quote asset once the owner enables it. The manifest carries the mint's 20-byte tag, trades move the stock between token accounts, and the graduated pool holds the stock. USD pricing comes from Jupiter.
• Bridging to and from Solana is not live yet: the program exposes bridge_mint / bridge_burn for a LayerZero OApp, and until then Solana legs trade independently.
