What a router is

Every trade on a Montra coin pays a fee in HYPE. A router takes the coin's creator side of it and spends it the way its route says.

The creator side goes to one address, the coin's recipient, which is usually the wallet that launched the coin. A router is a small contract made for one coin. Point the coin's fees at it, and the router claims them from Montra and spends them by its route.

A route has one to 8 legs. Each leg has a share, and the shares add up to 100%.

Four kinds of leg

  • Supply

    Buy back & burn

    Buys the coin in its own pool and burns it, so the supply falls.

  • Holders

    Pay holders

    Sends HYPE to the coin; Montra streams it to every holder over an hour.

  • A wallet

    Pay a wallet

    Sends HYPE to a wallet. The creator's wallet unless the route names another.

  • Supply and a wallet

    Buy back & send

    Buys the coin in its own pool and sends it to a wallet. The creator's wallet unless the route names another.

What can never change

Nobody, us included, can change a router's route, pause it or take what it holds.

There is no upgrade, no sweep and no rescue function. Here is what that rests on.

No owner

No function lets anyone change a router's route, pause it or take what it holds.

One fixed master

Every router is a minimal clone of one master contract that cannot be upgraded. Its address commits to its route: the same address can only ever be created with the same route.

One way

Once a coin's fees point at a router, they stay there. The router has no way to call Montra's updateRecipient, so it can never be moved, and a coin pointed at it cannot be pointed back.

One optional exception

The only value that can ever change is the creator's address, and only if the route was created with “creator can move its own slot”. Shares, other recipients and the guard still cannot change.

The factory

Its owner can set the platform fee and treasury for routers created later, and can pause the creation of new routers. It cannot touch a router that already exists.

03Money

Fees

Each amount a router collects pays 1% to the platform treasury first; the route splits the rest.

The platform fee

A router keeps the fee it was created with for life, and the route itself caps it at 1%, so the fee can never rise on a router that exists.

Nothing else to pay

The keeper creates your router and runs it at no cost to you; you pay only the gas of the one Montra transaction that points your fees.

04Money

The buyback guard

Every route fixes two numbers for its buybacks when it is created: a cap and a pause.

A buyback that anyone can trigger can be sandwiched: someone buys the coin, triggers the buyback at the higher price, then sells to it. Montra's own fee charges them both ways, so this only pays when one buyback is large next to the pool.

A cap

One buyback spends at most what moves the coin's price by 1%, measured against the pool's starting liquidity (the default; a route can set another value, or 0 for no cap). What is above the cap waits for the next buyback.

A pause

At least 60 seconds between two buybacks (the default), and never two in the same block.

Measured on a fork

On a copy of Elysium mainnet on 2026-11-09: with 9.9 HYPE waiting to be bought back, an attacker holding 30 HYPE made 5.80 HYPE against an uncapped buyback, and lost 0.36 HYPE against the 1% cap.

05Running a router

The keeper

Every step a router takes is a public call anyone can make. Our keeper makes them for you.

Anyone can call run on a router themselves. The keeper is a convenience, not a gatekeeper, and it owns nothing.

Create, run, report

  1. 01

    Create

    About every minute it creates the routers people have requested, at no cost to them.

  2. 02

    Run

    It runs each bound router that has work: at least 0.01 HYPE waiting, or 0.001 HYPE after 24 hours.

  3. 03

    Report

    Each run's claim, buyback and burn is recorded, and shows on the router's page.

06Running a router

Elysium's inbox

Elysium does not take transactions from everyone directly yet: they reach it through a delayed inbox on HyperEVM.

Why routers take minutes

A transaction lands after 11 seconds to 2 minutes (measured on 2026-11-09). That is why a new router takes 1 to 3 minutes to appear, and why the site waits a little after you point your fees.

Readable while it waits

While a transaction waits in the inbox it can be read on HyperEVM, so every buyback the keeper sends carries its own minimum output.

Risks

A router is simple, but it is not risk free.

Independent. Not affiliated with Montra or Kinetiq.

No outside audit

The contracts have their own tests and a review by their builders, not an audit by a third party.

Memecoins are volatile

Buybacks and holder payments do not hold a price up. A coin can still fall to nothing.

It depends on Montra

Routers claim through Montra's contracts and buy in Montra's pools. If Montra changes or stops them, a router may not be able to claim or buy.

Elysium is new

Its public RPC and explorer are not open yet, and transactions wait in an inbox before they land.

It cannot be undone

Pick the route with care: it is the only one this coin will have.
