The Elastos mainchain-sidechain architecture is designed in such a way that ELA is the native token on the mainchain and all supported sidechains. ELA can be mapped between the mainchain and its various sidechains at a 1:1 ratio.
In addition, wrapped versions of ELA may be available on other public blockchains. The table below lists the different existing versions of ELA.
|Elastos Mainchain||Native asset||A UTXO-model chain in which ELA is used to pay transaction fees, stake, register a validator, and participate in governance. The mainchain is the trust zone for the ecosystem on account of it being secured by Bitcoin.|
|Elastos Smart Chain (ESC)||Native asset||An EVM-compatible chain in which ELA is used to execute smart contracts. ESC is the primary place to deploy dApps (DeFi, NFTs, etc.).|
|Ethereum||ERC20 token||A Wrapped version of ELA available on Ethereum (created by bridging ELA from ESC to the Ethereum blockchain). [Contract Address]|
|Elastos Identity Chain (EID)||Native asset||An EVM-compatible chain specifically designed to support W3C compliant decentralized identifiers (DIDs).|
