Development Fund Proposal Submission
Proposal file: /proposals/2026-06-Eunoia-cip56-erc20-middleware.md
SIG Label: token-asset-standards Champion: Canton Foundation
---
Summary
MetaMask-compatible middleware exposing an Ethereum JSON-RPC facade over CIP-56 token contracts, plus a distributed indexer and an Ethereum↔Canton bridge relayer. Any EVM wallet, dapp, explorer, or indexer can transact against Canton-native tokens through the RPC surface it already uses, while Canton's privacy and finality guarantees are preserved. Phase 2 adds fully non-custodial signing via a MetaMask Snap plus an institutional custody path; all deliverables are Apache 2.0 open source.

Notes for Reviewers
- Resubmission of #440 (auto-closed for missing SIG label + Champion). Both now included: SIG label
token-asset-standardsand Champion Canton Foundation. - Includes a CIP-112 (Token Standard V2) migration plan with per-layer code-reuse estimates and a contingency clause for mid-Phase-2 ratification.
- Includes an explicit audit policy (independent third-party audits of the MetaMask Snap and the full middleware stack, reports published under
docs/audits/) and a post-grant long-term sustainment commitment funded by the Applicant. - Total request: 40M CC (Phase 1: 15M, Phase 2: 5M, Maintenance Y1: 10M, Y2: 10M). Project duration > 6 months, so the 6-month CC re-evaluation stipulation applies.
