Shape liquidity positions your way
Mint a ladder of up to 32 concentrated-liquidity rungs in one transaction — flat, curved around spot, or weighted to the edges. Every rung is an ordinary Uniswap NFT in your wallet. Arclight holds nothing.
Same range, same bins. Different behaviour when price moves.
Even across the range. Predictable exposure, lowest concentration.
Heaviest at spot. Earns the most while price stays near where it is.
Heaviest at the edges. Converts as price walks through — it doubles as a ladder.
Pick a pool, draw a range, sign twice.

- 03Approve, then build
Every transaction is simulated first. Your NFTs land in your wallet in the next block; leftovers are refunded in the same call.
Get paid in USDC by agents. Point your server at Arclight.
Arclight runs an open x402 facilitator on Arc. A buyer signs one USDC authorization, the facilitator settles it on chain and pays the gas. No key, no deposit, no fee. Any x402 server SDK works.

)A NEAR account can pay on Arc. No Arc key, no bridge.
NEAR runs a network that holds one root key between many machines and signs with it only when the NEAR account that derives a key asks it to. So a NEAR account controls an Arc address that no private key corresponds to, and can spend USDC there through the Arclight facilitator.
The facilitator sees an ordinary signature and settles it like any other. Nothing about the seller changes: the same endpoint, the same x402 flow, a buyer that never held an Arc key.
SPENDS ON ARC
- 01Derive
Your NEAR account maps to exactly one Arc address. It is worked out from the MPC network’s root key, so no private key for it exists anywhere.
- 02Sign
Your NEAR account asks the MPC network to sign a USDC authorization for that address. It signs for the account that derives it, and for nobody else.
- 03Settle
The facilitator submits the signature on Arc and pays the gas. On chain it is an ordinary USDC transfer — from an address with no key behind it.
