Intent trading

We compete to fill signed swaps on CoW Swap and other intent markets. We solve 1inch Fusion orders through Arctic Bastion.

CURRENT

Onchain arbitrage

We compare prices for the same asset across venues on a single chain and between networks. Fees, slippage, and inventory costs determine which trades make sense.

PLANNED

Leveraged trading on HyperEVM

We plan to develop leveraged trading strategies on decentralized exchanges on HyperEVM.

02 INTENT EXECUTION

From intent
to settlement.

A trader signs a swap with the terms they'll accept. We compete to find a route that meets those terms.

EXAMPLE SWAP

03 TRADE WALKTHROUGH

Arbitrage
across venues.

Compare a trade between two venues on one chain with a trade that moves an asset between chains.

WETH / USD Illustrative example

Venue A

$2,000per WETH

Buy venue

Venue B

$2,008per WETH

Sell venue

ONE CHAIN, TWO VENUES

01 QUOTED SPREAD

$8per WETH

Venue B quotes $8 more for one WETH than Venue A on the same chain. This is the spread before costs.

02 ROUTE CHECK

Compare two pools on one chain
Buy 1 WETH at Venue A
Sell 1 WETH at Venue B

Both swaps can execute in one transaction. The route still needs to account for gas and price movement.

03 EXAMPLE COSTS

Quoted spread: $8
Swap fees: -$3
Gas: -$2
Slippage allowance: -$1
Remaining spread: $2

If the quotes move or costs rise, the remaining spread can disappear.
