# ── Chainlink price feeds (per chain, per asset symbol) ───────────────────
# Only feeds listed here are polled by the PriceCache. Add more as new
# Venus markets become relevant. Feed addresses from docs.chain.link.
#
# Note on BTCB: docs.chain.link historically advertised the 8-decimal
# proxy 0x264990fb…1f0 as "BTC / USD" on BSC, but that address has no
# bytecode on mainnet today (decimals()/latestRoundData() abi-decode
# garbage). The address used below was discovered by walking Venus's
# ResilientOracle (0x6592b5DE…) → ChainlinkOracle facet (0x1B210344…)
# → tokenConfigs(BTCB) and then verified to be Chainlink-owned by
# matching its `owner()` (0xcb6754D5…) against the BNB/USD canonical
# feed's owner. It is an 18-decimal aggregator; PriceCache reads
# `decimals()` per feed and `CachedPrice::scaled_to` rescales, so the
# 8-vs-18 difference is invisible to consumers.
