About Architex

Built for a chain where gas is a dollar

On Arc, USDC is the gas token. There is no wrapped native coin and no guessing what a fee costs. Architex is designed around that: every pool is priced in dollars, every fee is paid in dollars, and every number you see is read straight from the chain.

The interface is intentionally quiet. Big numbers, clear routes, one button that moves money. You should be able to go from landing to a confirmed swap in under a minute.

Instant quotes

Prices are computed locally from pool reserves, so the screen never waits on the network to answer a keystroke.

Dollar native

USDC in, USDC out. Swaps, launch fees and creator fees are all settled in the currency you already hold.

Honest by default

No invented TVL, no fake volume. Every figure links back to the explorer and every contract source is public.

Keep it open

MIT-licensed contracts, permissionless fee collection, and plugins anyone can build.
