Mine. Every trillion verified hashes of the whole pool, one toad is drawn among everyone holding Spawn, weighted by how much each holds, and minted to the winner for free. There is no other way to get a new one.

Not from Toadex: there is no sale. Once a toad is yours it is an ordinary NFT on Robinhood Chain, so you can keep it, send it, or sell it like any other.

In the contract. The palette, every layer and every trait are written to contract storage, and the contract builds each toad’s image from them when asked. Nothing depends on an outside server.

The tickets are frozen and their fingerprint committed to the contract first; the random seed comes from a block made afterwards, so nobody knew it when the tickets were fixed. Every snapshot is public, so anyone can rebuild a draw and check the winner.

Points for verified mining work: one Spawn per million hashes. Spawn is your tickets for the next draw and carries over from draw to draw until you win. It cannot be sent, bought or sold.

An NVIDIA GPU and the Toadex miner, on Windows (the desktop app) or Linux. The NFT Mining page walks you through it.
