Pay with Plasma (ETH)

Why pay with Plasma

No chargebacks

ETH payments are final on-chain. No card-style disputes clawing funds back weeks later.

Borderless

Low fees

Network fees instead of card processing percentages, especially on efficient chains.

Private by default

No card number to hand over. You sign a transaction from your own wallet.

Pay by name

Send to a web3 name (ENS, Unstoppable Domains, FIO) instead of a long address.

Fast settlement

Merchants see your payment confirm quickly, then release goods or services.

Before you start

The setup is deliberately short. One wallet capable of holding Plasma and a little ETH for gas on its chain, one receiving address for the output, and you have everything: a web3 name resolves to the address just as well as the raw string. Read the preview before signing, since it carries the whole trade at a glance, the amounts in and out, the fee, and the network cost. The wallet remains yours throughout and signs nothing you have not seen on screen, which is the whole security posture in one sentence.

Fees and settlement

Two costs, both visible up front. The platform charges a flat 0.50% all-in on the swap and nothing hidden behind it, no spread and no routing cut. The network charges its gas in ETH, settling with about 1 sec blocks on Proof-of-Stake (Bitcoin-secured), itemized per leg in the preview. What settles is on-chain to the address you chose, under this asset's policy of Credited with a fast confirmation policy tuned to the chain's quick finality., and once confirmed the balance is entirely yours to move with no platform anywhere in the path.

Underneath, the aggregated DEX route executes the trade with all-or-nothing semantics: partial fills do not exist here, and a route unable to meet the bounds you approved reverts the whole transaction rather than settling something worse. Your exposure window between legs is therefore zero, the only cost of a failed attempt is its gas, and re-quoting is a click.
