Litemint has launched a fully non-custodial ERC-721 compliant bridge for Stellar NFTs to Ethereum, enabling secure use as profile pictures on Web3 services like Twitter. The bridge locks Stellar assets and mints corresponding non-transferable NFTs on Ethereum, with decentralized recovery mechanisms. It leverages Stellar's SEP-39 for metadata and ensures high security without relying on central entities.
Litemint introduced a decentralized bridge allowing Stellar-based NFTs, including those issued outside their platform, to be used securely on Ethereum as PFPs for services like Twitter and OpenSea. The bridge is 100% non-custodial: users lock assets on Stellar with a 1 stroop supply via a verified issuer and mint ERC-721 tokens on Ethereum, which are non-transferable and restricted from auctions or sales. Security is ensured through a hash-based secret mechanism for burning tokens on Ethereum, recoverable even if Litemint is offline by submitting transactions on Stellar. The Ethereum contract is verified on Etherscan, uses IPFS metadata per Stellar SEP-39, and blocks all transfers. Technical challenges like Ed25519 signature incompatibility led to a custom hash(x) signer approach. Examples include bridge accounts on Stellar Expert and burn transactions on Etherscan. Litemint plans further cross-chain interoperability features.
