FEI: Fei Protocol officially dissolved in August 2022 (Tribe DAO voted to redeem FEI->DAI and wind down operations). Observed in production: CoinGecko price for this token gets stuck/fails to refresh for 25+ minutes at a stretch while every other configured token refreshes normally each cycle. RENBTC: the backing bridge (RenVM) shut down in late 2022 following the Alameda/FTX collapse, with no active development since. On-chain volume is negligible (~$3/24h as observed), making it unsuitable as a fee token even though it still resolves a price. Neither token is a good candidate for fee collection: FEI is a defunct stablecoin and RENBTC is functionally illiquid.

Problem
Two tokens in Ethereum's default fee-token set (
STABLES_ETH/REN_TOKENS_ETH) correspond to defunct projects:Fix
Removed both from the active token sets, moved their addresses to commented-out entries in
config-token-addresses.tswith explanatory notes, following the existing convention used forRAILBSC/RAILPOLY.Verification
Ran a broadcaster with the current defaults on Ethereum mainnet; observed FEI failing to refresh in CoinGecko for 25+ min straight while 9 other tokens refreshed normally each ~16s cycle. RENBTC's backing bridge status confirmed via public reporting (Blockworks, CoinMarketCap) — RenVM has had no active development since 2022.
