#Quirks

  • 18 decimals on stablecoins. USDT and USDC on BNB Chain use 18 decimals, not 6. If you read raw values yourself, use the decimals value from /chains/bnb. Farbeam's amount is already adjusted.
  • Many blocks per poll. The measured distance between reads was about 38 blocks on 2026-11-04 UTC. The log scan was changed after that measurement and now reads up to 200 blocks per poll, so a slow poll is caught up on the next one. See indexing.
  • Estimated times. Older logs in a poll get a ts from a fixed block time of 0.75 s in the config. The measured block time on 2026-11-04 UTC was about 0.45 s, so these estimates can be off by several seconds. Use block for order.
  • **ETH here is a token.** Symbol ETH on this chain is a bridged BEP-20 token with kind: "token".
  • Base fee. base_fee_gwei read 0 in captures on this chain. Use gas_price_gwei for a cost estimate.
  • Source ids differ from the chain id. DexScreener and GeckoTerminal use bsc, and DefiLlama uses BSC. The API id is always bnb.

#Try it

curl -s "https://farbeamlabs.com/api/v1/chains/bnb"
const res = await fetch("https://farbeamlabs.com/api/v1/chains/bnb");
const { data } = await res.json();
console.log(data.status.status, data.status.head, data.tokens.length);
import requests

data = requests.get("https://farbeamlabs.com/api/v1/chains/bnb", timeout=30).json()["data"]
print(data["status"]["status"], data["status"]["head"], len(data["tokens"]))

A rule for this chain, from the Beamline examples style: chain == "bnb" and token in ["USDT", "USDC"] and usd >= 1m.
