How ARCO works

Swapping

Type an amount and we ask every venue on Arc for a price: ARCO's own pools and the other exchanges. You see all of them, the best one is picked for you and the trade goes there.

Inside ARCO there is nothing on top of the pool fee. When a better price lives somewhere else we still take you there, for a 0.05% routing fee that goes to ARCO lockers. Set your slippage, hit swap, done. Gas is paid in USDC because that is what Arc runs on.

Providing liquidity

Pools are concentrated. You do not spread your tokens over every possible price, you pick a range. Inside that range your capital is working and collecting the pool fee on every trade. Outside it you hold one token and wait.

That is the arch: lit where you earn, a wire cage where you do not. The crown is the price right now, green while it sits inside your range, red once it leaves.

• Tight range
  More fees per dollar, more time out of range.
• Wide or full range
  Fewer fees per dollar, almost never out of range.
• Your position is an NFT
  Collect fees any time, close whenever you want.
• The split
  LPs keep 87.5% of the fee. 12.5% goes to ARCO lockers.
• Only on ARCO
  Pools from other exchanges on Arc show up in Pools and Explore, tagged by venue, read only. Liquidity is added on ARCO pools alone.

Locking ARCO

Every fee the protocol keeps, from pools and from routing, is pushed into the staking vault and split among lockers by weight. Weight is your amount times a multiplier that grows with the lock length. Lock 1,000 ARCO for a year and you count like 4,000 locked for a week.

• Rewards arrive in USDC and ARCO, and in any other token the vault lists. Claim whenever.
• The ARCO itself comes back when the lock ends. There is no early exit.
• You can top up or extend a lock. The end date only moves later.
• Anyone can trigger the harvest that moves pool fees into the vault. Nobody holds them in between.
