⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

Verify token address and decimal count on-chain.

The token metadata specifies 18 decimals for a USDC variant (aArbUSDCn), which is unusual since standard USDC uses 6 decimals. While this may be intentional for an Aave-wrapped variant, confirm that address 0x625e7708f30ca75bfd92586e17077590c60eb4cd on Arbitrum actually has 18 decimals by checking the block explorer.

🌐 Web query:

What are the decimal places for token 0x625e7708f30ca75bfd92586e17077590c60eb4cd on Arbitrum?

💡 Result:

The token 0x625e7708f30ca75bfd92586e17077590c60eb4cd (Aave Arbitrum USDC / aArbUSDC) uses 6 decimals. [1]

Fix incorrect decimal count for aArbUSDCn token.

The token 0x625e7708f30ca75bfd92586e17077590c60eb4cd on Arbitrum uses 6 decimals, not 18 as currently specified in the metadata. Update the decimals field from 18 to 6.

In src/public/images/42161/0x625e7708f30ca75bfd92586e17077590c60eb4cd/info.json
around lines 1 to 10, the token metadata incorrectly sets "decimals": 18 for
aArbUSDCn (0x625e7708f30ca75bfd92586e17077590c60eb4cd) — change the decimals
value from 18 to 6 to reflect the token's actual 6-decimal precision; update the
JSON field accordingly and validate the file is still valid JSON after the edit.
