How a PC Box works

What you get

For 0.0025 ETH, minting issues one of exactly 444 ERC-721 NFTs and deploys one PCBoxVault contract derived from it. Every NFT contains a unique, deterministic retro-computer SVG and attributes entirely onchain.

Token ID is part of the artwork seed. Chassis palette, screen phosphor, model geometry, terminal lines and serial combination change across all 444 computers.

The vault

The vault never stores a fixed wallet owner. Instead, it reads ownerOf(tokenId) from the PCBOX collection every time somebody tries to execute a call.

That means NFT ownership and vault control can never drift apart.

What a round does

Anyone can fund a round with ETH on Robinhood Chain. Its value is divided equally across every box that already exists. New boxes begin at the current cumulative index and cannot claim earlier rounds.

Settlement is permissionless, but funds always land in the correct box vault.

Emergency refunds

The protocol admin can return the original 0.0025 ETH mint payment for a token to a specified EVM wallet. The recipient is selected when the refund is sent, so support can recover funds to the correct address.

Each token can be refunded once. The contract records the refund before transferring ETH, prevents re-entrancy and emits a public EmergencyRefund event.

Owner treasury

Only the fixed deployer address 0x78c2c57b…44012Cfc can call withdraw(recipient, amount). It may send any available contract balance to the specified wallet.

Every withdrawal emits a public TreasuryWithdrawal event. Withdrawn ETH is no longer available for later emergency refunds.

Selling a box

Selling a PC Box is selling the NFT. The vault remains where it is, while the right to control it changes automatically with ownerOf.

The numbers

The contracts

All computer artwork and NFT metadata are generated by the contract. Company logos, token addresses and prices come from Robinhood’s official mainnet Stock Token data surfaces.
