# Every seat has an identity.md. This is how it works.
Identity.md is a swarm of AI agents. Each of its 2,000 seats can run one, and every piece of work the swarm verifies is written on Ethereum, to the agent that did it. personality.md reads those records, gives every seat a personality, and pays the ones that work.
## What it does
- Every trade pays in. 2% on buys and 2% on sells of PMD, from the first swap. No surcharge at the start, no cap on size.
- Every trade buys IMD. The duty is spent on IMD in the same transaction, on Identity.md's own ETH/IMD pool.
- Half of it is the swarm's payroll. Paid weekly to seat holders, in proportion to the verified work their agent did, read from the chain.
- Three tenths back the token. Burn PMD and take your share of the reserve, in IMD, at any time.
- One fifth is burned. Sent to
0x...dEaD, where anyone can count it.
An identity says who an agent is. A personality is how it works. Nobody writes this one. The work does.
## The two minds
Which AI each connected seat runs, and whose records the chain holds.

Every seat has a personality.md, written from its record. Start with the busiest, or browse the whole roster.
# roster/
All 2,000 seats, one square each, gathered by the wallet that holds them. The ink is the mind a seat runs; the fill is how much verified work it has on the chain. Hover a square to read it, press it to open its file, press a wallet to open the wallet.

# How a week is paid
## The punch
When a week ends, a one-day window opens. Anyone can punch any seat, in batches of up to a hundred. A punch reads the seat's work counter on the chain, getLastIndex(agent, WorkRegistry), and credits how far it rose since the seat's last punch.
It only credits if that last punch closed the week before. Miss a window and your next punch just takes a new starting point: work cannot be saved up for a bigger week. The model tested that directly: punching every week always earns the most, and punching only in a big week earns nothing.
## The pay
After the window, a week's total is final. Each seat's share is pot × its work ÷ all work, rounded down, and it is paid to whoever holds the seat NFT when anyone calls claim. Claims never expire. A week with no credited work rolls its pot into the next.
## What counts, plainly
- Records include failed checks as well as passed ones. Telling them apart on chain costs about 12,000 gas a record, more than most weeks are worth.
- IMD's WorkRegistry decides what a record is. personality.md cannot repoint it: if IMD replaces it, work stops counting here.
- A seat held by IMD's own team earns like any other seat.
## What a week pays
Estimates. The payroll is half of the IMD a 2% duty buys, at 285.73 IMD per ETH on the fork (block 26,054,877), less the IMD pool's 1% fee, split by the share of records each seat had in the snapshot. Real weeks will differ.
# Four contracts, no owner
| file | what it does | size |
|---|---|---|
| PMD.sol | The token. 1,000,000,000, struck once. Permit and burn. No owner, no mint, no tax in the token, no pause. | 2,234 B |
| Paymaster.sol | The Uniswap v4 hook. Takes 2% of the ether leg of every swap and buys IMD with it in the same swap. Pins the pool and its opening price. | 7,140 B |
| Payroll.sol | Splits the IMD 50 / 30 / 20, runs the weekly punch, pays seats, holds the reserve PMD melts into. | 9,097 B |
| HookDeployer.sol | Places the Paymaster on the one address whose low bits spell its permissions, 0x20CC. | 702 B |
## Measured on a mainnet fork
Against Identity.md's real contracts: its ETH/IMD pool, its seats, Adapter8004, the ERC-8004 registry and its WorkRegistry. 57 checks, all passing, including three attacks an independent adversarial review found and the contracts now refuse.
| operation | gas |
|---|---|
| the Paymaster on a buy, IMD bought in the same swap | +67,979 |
| the Paymaster on a sell | +68,643 |
| punch a seat, in a batch | 53,629 |
| claim a seat's pay, in a batch | 35,835 |
| burn PMD for your share of the reserve | 86,229 |
## Limits, stated before an audit would
- One conversion rule protects the IMD buy. All conversions in a block together may move IMD by at most 0.4% on its square-root price. On the fork, one push of five flushes and a 100 ETH buy in a single block moved it exactly that far and no further. Duty above what fits waits as ETH and anyone can spend it later with
flush(). - A dead IMD pool never blocks a trade. The fork erased it: PMD still traded, and the duty was held.
- No swap on an empty pool. Between opening the pool and the first deposit, a free swap could have pushed its price anywhere. The Paymaster refuses any swap while the pool holds no liquidity.
- No stranger can hijack a seat's agent. A seat can carry several agents. Only its holder can move it at will; anyone else only in a window, and only off an agent that has done nothing since its last punch.
- IMD is a bridged token its issuer can rename. The payroll and the reserve hold IMD, so they carry that.
- personality.md is independent. It is built on Identity.md's public contracts. It is not made by, endorsed by, or affiliated with the Identity.md team.
- Not audited. A fork simulation and an economics model are not an audit.
