Migrator ETHBelgrade
MigratoOor is a community-goods tool to migrate a project's token from L1 to Scroll with the possibility to customize different types of incentives mechanisms in a verifiable way through zk-EVM and vLayer, and leveraging Scroll's L1SLOAD precompile.

Project Description
MigratoOoR is a tool that offers a simple framwork for projects who originally launched their tokens on Ethereum L1 to easily migrate their governance token to Scroll L2 in a trustless manner. Projects that initially launched their tokens on Ethereum L1 can take advantage of the lower costs and increased throughput of the Scroll rollup network, all while preserving Ethereum L1's security as a settlement layer and helping to alleviate network congestion.
A token migration includes the following steps:
- Migration Proposal: Protocol operators deploy a new governance ERC20 token on Scroll L2 through the MigratoOoR! dashboard and creates a migration proposal in MigratoOor! bridge contract. This token will be minted by the L1 -> L2 bridge as tokens migrate from L1.
- Migration Process: From a certain point in time the users can start to migrate the tokens through MigratoOoR! bridge in a trust-less manner.
- Rewards Distribution: As an additional configurable option, protocol operators can execute a final step of rewards distribution among the holders. These rewards are configurable through the MigratoOoR! dashboard and can incentivize users for early migrations and long-term holding.
Hosting the token's canonical supply on an L2 offers transaction cost benefits for both users and the project's team. It can also serve as an excellent way to align with Ethereum's rollup-centric scaling roadmap, particularly with Scroll's values and technical features. LDR; MigratoOoR! provides projects using our protocol with a decentralized, L2-native alternative to their pre-migration infrastructure setup.
How it's Made
To construct a trustless L1 -> L2 bridge for token migrations, MigratoOoR! leverages Scroll's new L1SLOAD precompile, which allows users to verify users token locks in the L1 bridge contract.
In the rewards distribution system MigratoOoR! migrator uses Vlayer time travel feature to compute and verify in ScroCrossll L2 the amount of rewards acquired by long therm holding the tokens.
To introduce multichain functionality for the new token on Scroll, protocol owners can opt to deploy it as a Chainlink Cross-Chain Token, unlocking enhanced interoperability across multiple chains.
