Abstract is an Ethereum Layer 2 blockchain built on a ZK rollup stack, focused on consumer applications and mass adoption. It launched mainnet in 2025 with EVM compatibility, low fees, and fast transactions, using ETH as its native gas token.

Two things and you are ready. A wallet that can hold Abstract and a little ETH 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.
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 ZK Rollup, 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 suited to quick ZK rollup blocks., and once confirmed the balance is entirely yours to move with no platform anywhere in the path.
Execution runs through the aggregated DEX route, which means the number you approved is the number that happens or the transaction reverts: swaps are atomic, with no half-settled state to unwind and no exposure window between legs. If a route cannot fill at your approved bounds it fails cleanly and you re-quote, which is the failure mode you want, cheap and loud rather than silent and expensive.
One account unlocks accept, swap, buy, and the rest of the U.CASH network across 35 networks.
