FAQ

Did DOME invent Orbital?

No. Orbital was designed by Dave White, Dan Robinson and Ciamac Moallemi at Paradigm and published in 2025, where they called it just a design. DOME is a Solana program that implements it.

Why one pool instead of many pairs?

Dollar liquidity on Solana is split across many pairwise pools. A large swap between two less common dollars has to route through several of them and pays each one's price impact. In one Orbital pool every band quotes every pair at once, so a swap takes one hop.

Measured on 2026-10-17: today's best Jupiter route loses 42 bp swapping $1M of USDT to PYUSD. In the engine's model, one $40M DOME pool loses about 5.2 bp plus the 2 bp fee. On pairs that already have deep books, such as USDC to PYUSD, Jupiter is still cheaper at $1M unless the pool is large and its liquidity sits in tight bands.

What happens when a stablecoin depegs?

Its price falls, so traders sell it into the pool. Each band absorbs it only until its own edge, then stops taking it and keeps trading the other coins. A $0.99 band stops at $0.99; a $0.90 band at $0.90. The full band covers every price and takes the most.

Can someone list a bad coin into my pool?

No. A pool's coins are fixed when it is created; its address is the hash of exactly those mints. A different set of coins is a different pool, and you choose which pool you deposit into.

Is there an oracle?

No. Prices come from the reserves.

Who can change the fee?

Nobody. The fee (2 basis points) and the burn share (25% of it) are constants compiled into the program.

Where does the burn happen?

buy_and_burn buys DOME on a Raydium CP-Swap pool named once at launch and burns every token it buys in the same instruction. Anyone can call it.

Is there a token address yet?

No. DOME has not launched. No token address is published before launch; anything claiming to be one is not ours.

How many coins can one pool hold?

Between 2 and 16. All coins of a pool must use the same decimals.
