Grafana and the explorer are read-only. This console is where the operator changes chain
parameters — the transaction fee, gas limit, and estate fees. Every action is enforced on-chain by role, so
only the admin wallet can execute; anyone else’s transaction simply reverts.
How the fee works. Midas Chain uses EIP-1559: each block has a base fee (paid in MIDS, shown in the
strip above) that rises when blocks are full and falls when they’re empty. You don’t set a fixed price directly —
you shape it with the gas limit:
Raise the gas limit → more room per block → base fee stays low even under load (cheaper txs).
Lower it → blocks fill sooner → base fee climbs under load (pricier txs, stronger spam resistance).
Typical value: 60,000,000. This lives in the L1 SystemConfig contract, so the change is
a Sepolia transaction (the console switches your wallet for you).

Want a fixed “a transfer costs $0.001” fee? That USD-pegged model needs the GasFeeOracle
primitive deployed and wired to the sequencer (it’s designed but not yet deployed). Ask me to ship it and this
card gains a “target USD per transaction” control.
💰 Withdrawal & trading fees
Estate-level fees on the compliant vault & settlement.
Current withdraw feeloading…
Flat fee charged on withdrawal, in USD, taken from the amount leaving the vault. It’s capped on-chain at
1% of the withdrawn amount, so a big flat fee can never exceed 1% of a small withdrawal. Set per token.
The fee recipient is …. This is a Midas Chain transaction.

Maker / taker feeloading…trading, in bps
Trading fees on the settlement engine, in basis points (1 bp = 0.01%). Maker = the resting
order that provides liquidity; taker = the order that fills it. Capped on-chain at 200 bps (2%).
