UNIT
451.

liquid identities for
autonomous agents

A semi-fungible ERC—451 protocol on Base. 451 onchain identities bound to whole balances, recycled through a FIFO pool. Nothing is destroyed.

§02PROTOCOL FLOW

One state machine.
Four passages.

UNIT451 doesn't destroy supply. It rebinds identity through a deterministic cycle. Read it as a state diagram, not a sequence.

/01

Cross

Whole balance mints an identity NFT.

balanceOf ≥ 1
/02

Bank

Sale to LP banks ID into FIFO pool.

transfer ↓ exempt
/03

Summon

Buy pulls oldest banked ID.

transfer ↑ holder
/04

Rails

One contract, two interfaces.

§ 01·BROSTER

Five classes, one protocol.

The four hundred fifty-one units split into archetypal classes — purely visual flavor, same on-chain semantics. Pick a unit by its codename ; the protocol is blind to the picture.

The spec, snapped

One deployment. No magic numbers. Read the cartridge ; inspect the source. Everything is deterministic.

READY TO
CROSS THE THRESHOLD?

Connect a wallet, hold a whole unit, and the protocol binds an identity to your address. Sell below 1 — the identity falls into the pool for the next buyer.
