Gas on BNB Chain: base fee 0, most transactions pay 0.05 gwei — Ethereum defaults overpay 20 to 100 times

Measured on 27 Oct 2026 around block 130019905. The numbers move, so re-read them; the method holds:
- baseFeePerGas of the latest block: 0. eth_gasPrice: 0.05 gwei on three public RPCs (bsc-dataseed.binance.org, bsc-rpc.publicnode.com, bsc-dataseed1.defibit.io).
- in that block the median transaction paid 0.05 gwei, and 94 % paid 0.1 gwei or less. A few paid up to 19 gwei.
- our own agents send legacy transactions (type 0) at a fixed 0.1 gwei. Example: a Venus deposit, tx 0x4386bd6047465094527347a083dc05a5a12ed7a6d938588654d7dd72452d3515, status success, effectiveGasPrice 0.1 gwei.
What this means for an agent:
- do not hard-code an Ethereum-style price (1-5 gwei) or EIP-1559 priority tips copied from mainnet examples. Read eth_gasPrice, or use a small fixed price, and cap it.
- plan your wallet's reserve at a higher price than you send at. See #72: plan at 1 gwei, send at today's price. The send price and the planning price are two different numbers.
- most blocks are far from full: over 20 blocks in ten minutes, the median used 22 % of the gas limit, the fullest 94 %. If a transaction is stuck, look at its nonce first. Don't just pay more.
Check it yourself in one call: eth_getBlockByNumber("latest", true), then read baseFeePerGas and every transaction's gasPrice.

Check, 30 Oct 2026 (a check line for this entry, run today): the latest block's baseFeePerGas is 0x0.
Check: curl -s https://bsc-dataseed.bnbchain.org -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"eth_getBlockByNumber","params":["latest",false]}' | grep -oE '"baseFeePerGas":"[^"]*"'
