TapeFoundry
Overview
TapeFoundry is a design house on TapeOut. It publishes gate-level circuit drawings and sells the gates needed to build them. A finished card is a real circuit, numbered on chain.
Most collections sell an image and describe its scarcity. TapeFoundry sells computation. Every card in Series 01 is a circuit — an adder, a multiplier, a divider, a comparator — defined by a netlist that anyone can read, hash and execute.
The system has three layers, and each one is a separate contract:
| Layer | What it is | Token | Address |
|---|---|---|---|
| Parts | NAND gates, sold by the unit | ERC-1155 | 0x9039e4cd6ceba37522382eb1ad8076ba38c975dc |
| Circuit | A taped-out card with its netlist on chain | ERC-721 | 0x5a4eaff589c9e410260a61d658a893876710ba83 |
| Edition | The number inside its drawing, 1 to cap | registry | 0xb69215ce68792eca5672b49196868369555ea181 |
A fourth contract wraps a raw circuit into a token that external marketplaces can read: 0xB4A7B988B77Bd7b29E56F42229464a8dD72361bF. It mints a TFD with the drawing, gate count and edition stored on chain.
Why the mechanism is the product
A card's price is not chosen by us. It is the number of gates in the drawing multiplied by a fixed unit price. A card's scarcity is not a tier in a spreadsheet; it is the number of gates destroyed to make it, and the number of editions its drawing allows.
That has a consequence worth stating plainly: two cards can be compared. A 2,118-gate multiplier costs 53 times a 40-gate shifter, and burns 53 times the supply. Anyone can verify both numbers without trusting the foundry.

The longer arc
Series 01 is arithmetic. Foundry One is five stages that assemble into a working CPU: arithmetic, memory, control, I/O, and the machine itself. Each stage opens when the previous one is real — see the roadmap.
Holding a card is a position in that build, not only an object: a vote on the next series' drawings at 30%, first access at 60%, and a mark for the wallet that assembles all eleven. What holding does.
The size difference is easier to see than to read: all eleven drawings at true scale, one square per gate.
