We currently support the Ethereum Mainnet (ETH) and Optimism (OP) blockchains.
Optimism is a Layer 2 (L2) solution for Ethereum. If you are experiencing high gas fees on Ethereum, you can try using Optimism to greatly reduce any fees.
You can learn more about the two blockchains below:
Ethereum
Ethereum is a decentralized blockchain with smart contract functionality. Its native currency is Ether (ETH) which is used for transaction fees. Ethereum uses proof-of-stake (PoS) consensus, eliminating energy-intensive mining. Gas fees are paid to the validator and are determined by network capacity and demand. Platforms do not touch or have any control over the gas fees.

Optimism
Optimism is a fast, stable, and scalable Layer 2 blockchain that is 10x cheaper and 6x faster than Ethereum.
On Optimism, transaction data is batched and "rolled up" to the Ethereum Mainnet. A sequencer bundles these transactions, significantly reducing costs and improving transaction speeds. All transactions are posted to Ethereum, ensuring security and longevity.
