Summary

Adds metadata and the official icon for USD8 on Ethereum mainnet.

Chain CAIP-19 asset ID Name Symbol Decimals
Ethereum eip155:1/erc20:0x2fE01f5E235eeaB9045066f873f531dE20f31947 USD8 USD8 18

ERC-20 (not ERC-721/1155). Name, symbol and decimals match the contract's name(), symbol() and decimals().

What USD8 is

USD8 is a stablecoin minted 1:1 against USDC through the USD8 Treasury and redeemed against the same USDC reserve. Holders get free DeFi hack cover built in: their onchain usage of vetted protocols becomes coverage automatically (up to 80% of hack losses), backed by onchain Cover Pools. Supply comes from deposits rather than trading, so DEX volume is low by design.

Why

USD8 holders don't see their balance in MetaMask unless they import the token manually: https://token.api.cx.metamask.io/token/1?address=0x2fE01f5E235eeaB9045066f873f531dE20f31947 currently lists only the dynamic aggregator. This adds the canonical name, symbol and icon.

Verification

Activity

  • Live on Ethereum mainnet since Oct 17, 2026 (private beta); ~41.7K USD8 supply, ~$64K protocol TVL
  • DefiLlama: https://defillama.com/protocol/usd8
  • Indexed by DeBank (token and protocol), Zerion and Octav; routable on LI.FI/Jumper; logo live on Matcha

Icon

SVG, square 100x100 canvas, gold coin mark that stays visible on light and dark themes. Same file as the logo served at https://usd8.fi.
