How a call works

Every call is a contract with the crowd

  1. 1

    Name the call

    A caller names a token or a pool, a direction, a target price and a deadline, and puts their own USDC behind it. That stake seeds the market from the first trade.

  2. 2

    Back it or fade it

    Anyone can buy HIT shares if they think the call lands, or MISS shares if they think it will not. Every purchase moves the price.

  3. 3

    The chain settles

    The Chainlink feed decides. Reach the target, hold it for ten minutes before the deadline, and HIT pays one dollar a share. Otherwise MISS does.

The arena

One arena, four moves.

Arccast is where you make the call, trade the crowd, and let the chain keep score. Create, trade, settle, stake.

    Create

    Open a call on any token with a live price on Arc, or on a Uniswap pool. Set the target and the deadline, stake your side, and the market is live.

  • 2 of 4

    Trade

    Buy HIT or MISS shares on any open call. Prices move with every trade, so conviction has a price you can see.

  • 3 of 4

    Settle

    No judges. The Chainlink feed, the ten minute hold and the deadline decide, and winning shares pay one dollar each.

    Stake

    Stake $CAST to take your tier. Rewards from the protocol's revenue are paid out by tier in USDC.

Rules set before the fight

Settled by the feed, not by a vote.

Chainlink price feeds
  1. The target must be reached

    The price reaches the target on the Chainlink feed the call was opened against: at or above the target on a LONG call, at or below it on a SHORT call.

  2. It must hold for ten minutes

    It then holds at or past the target for ten unbroken minutes. One price back across the target ends the hold, and the ten minutes start again.

  3. It must happen before the deadline

    The hold has to finish before the deadline. If it never does, the call settles MISS once the deadline passes.

The token

Stake it to take your tier.

Stake $CAST to claim your place in the arena. Rise from Citizen through Gladiator, Centurion and Commander to Emperor. Your tier sets how much of the protocol's rewards you take, paid out in USDC.
