Add UST1 unstablecoin (Terra Classic) - #903
Conversation
CW20 token_info circulating supply as peggedUSD. Crypto-backed via ust1-window / vFDUSD. No $1 hardcode.
📝 WalkthroughWalkthroughChangesUST1 Terra Classic integration
Merge Risk: 🔵 Low · up to A stalled Terra Classic request could delay UST1 circulating-supply updates because the fetch has no request timeout. The PR is otherwise mergeable with explicit owner follow-up to add a per-attempt timeout. Sequence Diagram(s)sequenceDiagram

It does not follow the repository template and omits several template fields, including the logo, mintRedeemDescription, wiki, Twitter link, and audit links. Resolution Use the repository template headings and complete each field. Add the missing mintRedeemDescription, wiki, Twitter, logo, and audit information. Explicitly leave Coingecko and Coinmarketcap fields empty when they do not apply, and identify any unavailable metadata as N/A.

Axios 1.7.7 request config timeout default 0 documentation async-retry 1.3.1 retries only when promise rejects
💡 Result:
In Axios 1.7.7, the request configuration property timeout specifies the number of milliseconds before a request times out, with a default value of 0, which signifies no timeout [1][2][3]. Regarding async-retry 1.3.1, the library is designed to retry when the provided function throws an error or returns a promise that rejects [4][5]. If the function resolves successfully, async-retry considers the operation complete and does not retry [4][5]. Therefore, retries only occur when the promise rejects or an error is thrown [4][5]. Note that if you need to abort retries manually within the function, you can invoke the bail function provided as the first argument to the retrier [4][5].

Bound the Terra LCD request.
axios.get(url) uses Axios 1.7.7 with the default timeout: 0. A stalled request remains pending, so async-retry cannot start another attempt and terraMinted may not publish a supply update.
Set a per-attempt timeout.
