    Polygon ⇄ NEAR · atomic swaps


    Swap WETH on Polygon for NEAR without a bridge holding your funds. Both chains lock to the same hash, so either everything settles or everything refunds.

    Launch swap →How it works

    After the reveal · settled

    Both claims land, or the timelocks expire and the funds go back. No bridge custody, no counterparty risk.

    Secret revealed in time

    Both sides claim.

    The maker claims NEAR before the +30 min withdrawal deadline, and the same secret lets the resolver claim WETH on Polygon.

    Secret never revealed

    Everything refunds.

    Nothing can be claimed without the secret. After the +1.5 h cancellation time, the resolver refunds the expired HTLC.
