Mantle is an Ethereum Layer 2 with a modular architecture that separates execution from data availability. Its native token MNT is used for gas and governance, and the chain is fully EVM-compatible.
Straight into the app: Swap MNT · Buy MNT · Get UCASH with MNT
Modular Optimistic L2 (settles to Ethereum). Settlement on U.CASH is non-custodial: every payment moves on-chain, direct to a wallet you control. Confirmation policy for Mantle: Credited after L2 confirmation; deeper finality once the batch settles on Ethereum..

Two things and you are ready. A wallet that can hold Mantle and a little MNT for gas on its chain, and the receiving address you want the output delivered to, which can be a raw address or a web3 name where the wallet resolves one. The preview shows the full picture before anything is signed: what leaves, what arrives, the fee, and the network cost. Nothing in the flow asks you to hand over keys; the wallet stays yours and signs only what you approved on screen.
The cost picture is two lines. The platform side is a flat 0.50% all-in on the swap, quoted before you sign, with no spread and no routing cut behind it. The network side is gas paid in MNT, settling with about 2 sec blocks on Modular Optimistic L2 (settles to Ethereum), which the preview itemizes per leg. Settlement is on-chain to the address you chose: Credited after L2 confirmation; deeper finality once the batch settles on Ethereum. on this asset, after which the balance is spendable and non-custodial in the fullest sense, yours to move with no platform 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.
One account unlocks accept, swap, buy, and the rest of the U.CASH network across 35 networks.
