A draft ERC posted to Ethereum Magicians on October 31 proposes a model for transferring ERC-20 tokens between EVM chains with different issuers using different signer policies. Forum author 0xsptt describes the work as an early-stage proposal and invites feedback.
The opening post, created at 12:00 UTC, describes a burn-and-mint process: tokens would be destroyed on the originating chain and issued on the receiving chain. It divides the proposed implementation into three contract layers, each with a different responsibility.
The transport contract would carry messages and check threshold signatures using EIP-712. The described signature scope includes the deployment domain, both chains, both relays, and the verifier set's version and configuration. A transfer contract would manage the transfer lifecycle and token mappings. An execution contract would hold the permission to mint and burn.
The multi-issuer element sits within that shared structure. Each issuer would bind its tokens to a separate verifier set, including its own keys, signing threshold and rotation policy. The destination side would check the issuer-to-verifier binding when handling delivery. The post gives different signing thresholds as configuration examples; it does not present measurements from a running deployment.
For implementers, this separates an issuer's signing-policy configuration from the contracts used in common. The proposer explicitly identifies the relay, router and executor, alongside their governance and upgrade administration, as shared components. Issuer-specific signer settings therefore do not remove that common administrative layer from the described architecture.
The announcement concerns a proposed token-transfer specification. The forum post establishes the design being put forward, while acceptance as an ERC, implementation status and production adoption remain unverified. Its invitation for feedback should not be read as an announcement of an approved standard or an operating bridge.
