Rates Engine v0.5.0-rc.46

[v0.5.0-rc.46] — 2026-05-11

Added

• /v1/assets?network=<chain> filter. network=stellar (or
  omitted) returns the indexer's full Stellar-network catalogue;
  ethereum|solana|polygon|base|arbitrum|tron|bitcoin|bsc| avalanche|xrpl projects the verified-currency catalogue entries
  with a matching networks[] row into AssetDetail (type: external, asset_id: <network>:<contract>). Drives the
  /blockchains/{network} click-through.
• AssetDetail coin-equivalence overlay. /v1/assets/{id} now
  includes price_usd, change_1h_pct, change_7d_pct,
  top_markets, price_history_24h, price_history_7d,
  markets_count, trade_count_24h, ath, and
  issuer_scam_reason — lifted from the coins catalogue so the
  surface is a superset of /v1/coins/{slug}. Closes the
  wire-shape gap blocking the /v1/coins → /v1/assets consumer
  migration. Skipped for fiat:* assets (no coin row).
• /v1/chart?price_type=market_cap (fiat phase). Returns a
  USD-denominated market-cap series for fiat:CCY base assets,
  computed on-the-fly as M2 (verified-currency catalogue) × daily
  FX rate (fx_quotes). Crypto market-cap-over-time is deferred
  pending the market_cap_1d CAGG (returns 501 today with a
  clear "deferred" message). Closes the explorer's "no market
  cap over time" gap for the currencies surface.

Removed (explorer)

• /currencies/* page tree. The 7 files in
  web/explorer/src/app/currencies/ (~2400 lines) are deleted;
  routes consolidated under /assets/{friendly-slug}. Internal
  link generators (HomeCurrencies, SearchModal, convert pages,
  sitemap) now use the new lib/fiat-slugs.ts ticker → slug map.
• _redirects consolidated under CF's free-plan ~100-rule
  cap. 221 → 52 rules. Cloudflare Pages silently drops rules
  beyond the cap; the CNY rule was at position #117 and
  consistently failed to fire. Trims: drop UPPERCASE ISO
  variants, drop no-trailing-slash forms (Next.js
  trailingSlash:true 308-redirects bare URLs first), drop
  secondary aliases.
