[genedeyev]

Name, symbol and decimals are read from the contract, not from a listing:

name()     Stobox Token
symbol()   STBU
decimals() 18

Against the criteria in CONTRIBUTING.md

• Official website referencing the address: https://www.stobox.io/stbu – the contract address is on the page, and the token list at https://stbu.stobox.io/stbu.tokenlist.json carries the same address and logo.
• Website explains the project: Stobox has built tokenization infrastructure since 2018. STBU pays for services of the Stobox group at a discount on the list price. https://www.stobox.io
• Signs of activity: the token migrated one-for-one from Ethereum, BNB Chain, Polygon and Arbitrum to this single contract on Base on 15 September 2026, with a live claim portal at https://stbu.stobox.io and public GitHub activity at https://github.com/StoboxTechnologies.
• Verified source code: yes – STBUToken, solc v0.8.28, verified on BaseScan. https://basescan.org/address/0xe0c0F44A84CC4a60206360006ebA237a5e8fC2dd#code
• CoinGecko: https://www.coingecko.com/en/coins/stobox-token (the record points at this Base contract).

Against STYLEGUIDE.md

The icon is an SVG of pure vector paths – no <image>, no <foreignObject>, no nested <svg>, no animation, 1.5 KB.

The one change from the logo we publish elsewhere: the background is a square filling the whole artboard rather than a rounded square, because the guide asks for exactly that – a rounded background with transparent corners loses its corners to the circular crop. Rendered and checked in light and dark at 96, 48, 32 and 20 px in a circular mask; the mark stays inside the safe area and stays legible at the smallest size.

Why it matters for MetaMask users

token.api.cx.metamask.io/token/8453 already answers for this token with the right symbol and decimals, and the price API quotes it, but static.cx.metamask.io/api/v1/tokenIcons/8453/0xe0c0f44a…png returns 403. Holders who see the token therefore see it grey and unnamed next to a logoed ETH, which is how a fake looks. This PR gives it its own mark.

Note

Low Risk
Additive token metadata and static icon only; no runtime or security-sensitive code paths.

Overview
Registers Stobox Token (STBU) on Base (0xe0c0F44A…) in the token assets repo by adding a new metadata entry and matching SVG icon.

The JSON lists name, symbol, decimals (18), and points the logo field at the new vector icon (square gradient background with the STBU mark). No application or contract code changes—only list assets so MetaMask can show the correct name and icon instead of a generic placeholder.
