Tokens created on other chains (for example, ERC-20, ERC-721, and ERC-1155 on Ethereum) can be imported to Efinity using a bridge.
Snowfork is building an open-source bridge design between Ethereum and Polkadot. The bridge is compatible with ERC-20 tokens, and Enjin will contribute support for an ERC-1155 bridge.
Because the Enjin Ecosystem has its roots in Ethereum, Paratokens will be backward-compatible with ERC-1155 - including tokens created on Efinity. Certain features developed for Efinity will be backported to Ethereum, but we expect that most users will prefer to leave their tokens on Efinity because of its next-generation usability and speed.
There are certain cases where tokens could lose consistency between their source blockchain and the Efinity parachain. For example, an Enjin ERC-1155 token might be moved to Efinity and then be made “non-transferable” by its creator on Ethereum.
The bridge module will update and freeze parameters as needed to synchronize with the source chain.
Development of new bridge modules by the open-source community can be incentivized using the Efinity Treasury and the Ecosystem Fund. Bridges may be added to the Verifier through governance referendums so that Efinity may support future blockchains.
