What is a ZK-rollup and how does Loopring use it?

A ZK-rollup batches transactions off-chain and submits a cryptographic proof (ZK-SNARK) to Ethereum, proving all transactions are valid without revealing individual details. Loopring uses this for its DEX.

Can I swap LRC without KYC?

Yes. SyntheticSwap supports LRC swaps with no registration or identity verification.

Is Loopring Exchange non-custodial?

Yes. Users retain custody of their funds — they cannot be accessed by Loopring operators. Assets in the L2 can be withdrawn to Ethereum at any time.

What is the connection between Loopring and GameStop?

GameStop partnered with Loopring to launch an NFT marketplace using Loopring's ZK-rollup technology, though the GameStop NFT marketplace was later shut down.

How fast is the Loopring exchange?

Loopring's ZK-rollup achieves up to 2,000 transactions per second with near-instant finality and fees that are 100x cheaper than Ethereum mainnet.

About Loopring

Loopring (LRC) is an open-source ZK-rollup protocol for building high-throughput, low-cost decentralized exchanges and payment apps on Ethereum. By batching thousands of transactions off-chain and submitting ZK proofs to Ethereum, Loopring achieves up to 2,000 TPS at a fraction of Ethereum mainnet gas costs while inheriting Ethereum's full security. The Loopring Exchange (loopring.io) lets users trade and transfer tokens in a non-custodial environment. LRC is the protocol token used for staking by exchange operators and for governance. Loopring pioneered ZK-rollup DEX technology and influenced many later ZK scaling solutions.

How to Swap LRC

Exchanging Loopring (LRC) on SyntheticSwap is straightforward and requires no registration or identity verification. LRC is an ERC-20 token built on Ethereum, so you can use MetaMask, Coinbase Wallet, Trust Wallet, or any other Ethereum-compatible wallet to send and receive it. Select LRC in the SyntheticSwap interface, choose your destination coin, enter a receiving address, and confirm the rate. Your swap processes automatically — the destination token arrives in your wallet once the Ethereum transaction is confirmed.

How to Store LRC

LRC (ERC-20) is stored in MetaMask, Ledger, Trust Wallet, or any Ethereum wallet. For using Loopring's ZK-rollup DEX, visit loopring.io and connect your wallet — your funds will be in the L2 environment but can be withdrawn to L1 Ethereum at any time.
