Note

Low Risk
Adds a new ERC-20 asset entry (metadata + SVG logo) without changing any runtime logic; main risk is incorrect token details or asset ID/path causing display issues.

Overview
Adds contract metadata for the EURC (Circle Euro Coin) ERC-20 on Optimism (eip155:10), including name/symbol, decimals: 6, and a logo reference.

Introduces a new corresponding SVG token icon at the CAIP-19 path used by the metadata.

Potentially unofficial EURC token added to registry

High Severity

Circle's official documentation (as of April 2026) lists EURC on Avalanche, Base, Ethereum, Solana, Stellar, and World Chain only — Optimism is not a supported network. The address 0xDCB612005417Dc906fF72c87DF732e5a90D49e11 appears on Scroll attributed to Ether.fi, not Circle. The logo SVG also uses an inverted color scheme (white background, blue foreground) compared to the existing official EURC entry on Ethereum in this repo (eip155:1, which uses a blue background with white foreground). These discrepancies suggest this may not be an official Circle deployment and warrant verification before merging.
