Request cr-2e8a22c3 (Chart Reviewer feedback on the USDC share-of-volume card).

What changed

  • src/lib/usdcShareCard.ts: builds the card as a 1024px SVG from src/lib/issuance.ts (same numbers as /issuance and /summary).
  • scripts/usdc-share-card.ts: writes docs/img/usdc-share-card.svg and .png (PNG needs rsvg-convert).
  • npm run card:usdc-share:fresh: re-pulls the event logs, then renders. npm run card:usdc-share renders from the snapshot and refuses one that is not from today (--allow-stale overrides).
  • src/lib/usdcShareCard.check.ts (runs in npm test): numbers match the snapshot, as-of date present, every $ is $x.xB, every share is x.x%, only navy / red / white, smallest font >= 26px.
  • src/data/issuance.json: re-pulled from Tenderly's public gateway, asOf 2026-10-25.

Result

Card reads 85.0% of $1,016.8B (USDC $864.8B), through the week of Oct 12, 2026, data as of Oct 25, 2026. The headline did not move after the re-pull: the week of Oct 19 is still partial, so it is dropped, and completed weeks are unchanged.

Checks

npm test (7 scripts) passes, npm run lint and tsc --noEmit clean. The card was rendered and viewed at 1024px.

Notes

  • The card did not exist in the repo; this adds it. Wording ("mostly market-maker churn") follows /summary.
  • Supply and rate snapshots (backfill-context.mjs) were not re-run; the card does not use them.
  • The share (85.0%) is Ethereum-only gross volume across six assets, with Circle CCTP excluded.
