Launch a token.It hires a purser.
Every token launched through Purserfi gets its own on-chain officer: a wallet that collects the token’s trading fees, keeps itself fuelled with gas, and holds its liquidity positions across every venue. From block one, unattended.
What the purser does
Four duties. Each one is a function the operator key can call, and nothing else.
How it works
- 01Launch through PurserfiName, symbol, supply, quote currency, strategy. The fee recipient is set to the vault at launch, so there is no later transfer step.
- 02The purser claims fees on a scheduleClaiming is permissionless; the purser just does it reliably. Proceeds go to the vault whoever calls.
- 03It refuels its own gas within the capA small draw from the vault when the balance runs low. Usage against the cap is shown on the launch page.
- 04It builds laddersIn the token's own pool, or across the board, per the strategy the creator picked. Every rung and amount is on-chain and on the launch page.
- 05The creator withdraws or exits, any timeWithdraw from the vault, stop the operator, or hand the fee stream back to any address. Each is one transaction and needs nobody's permission.
A ladder, rung by rung
Aligned positions across a price band. Rungs below price hold the quote currency; rungs above hold the token. Only the rung the price sits in earns at any moment, so the ladder is built to be crossed.
What the contracts do
Stated as properties you can read on-chain, not as a promise.
Venues and quote currencies
Ladders are built where a builder is deployed. Positions are read everywhere. Venue parameters →
Tokenized equities are shown in token units. No dollar figure is attached to them until a price source exists.
Questions
Only the creator address recorded at launch or onboarding. The purser holds an operator key that can call claim, sweep, refuel and the ladder builder. There is no function on the vault that lets the operator send value anywhere except back into the vault or, within the daily cap, to its own gas balance.
It refuels itself from the vault, up to a fixed amount per rolling window. If the cap is spent and the balance hits zero, it stops acting until the window resets. Claims are permissionless, so anyone can still claim on the token's behalf in the meantime; proceeds go to the vault either way.
Yes, in one transaction. setOperator(0) halts every purser action. You can set a new operator later, or hand the fee stream to any address you choose. Neither step needs us.
Because that figure cannot be computed honestly. TVL is reported by a third party and is sometimes missing; fee yield divides measured revenue by that TVL, so it is missing too. A dash always comes with the reason. A zero means we measured zero.
Measured: summed by our indexer from swaps on-chain. Reported: taken from a third party and shown as given. Derived: computed from the other two, so it inherits the weaker source. Every number on both sites carries one of the three.
Not yet. Balances in NVDA, GLD and the others are shown in token units with a dash where a dollar figure would be. We will attach one when a price source we can verify exists.
