1gwei.dev

A no-KYC "gas station" for when you're stuck without native gas. 1gwei.dev lets you pay a small invoice in Monero (private) or Lightning (fast) and receive native gas — ETH, or the chain's own token — on 8 chains (Ethereum, Arbitrum, Base, Polygon, BNB, HyperEVM, Robinhood, Sepolia), delivered to any address in minutes. No account, no email, no SIM, no login: paste a destination, pay a one-time invoice, receive gas. Amounts are deliberately tiny ($0.72–$3.59, or custom) — enough to unstick a wallet, approve a token, claim an airdrop, fund a fresh address unlinked to any exchange, or bankroll a dev/testnet wallet.

Unusually honest about what it is. The site *labels itself* a "custodial gas station" and tells you plainly: *"send only the small amount of gas you need, then move on — it isn't an exchange or a savings account."* Live ETH/USD spot pricing with the margin shown up front, plus sensible reliability handling (never double-pays, retries failed sends, keeps the order open until the gas is broadcast). That proactive custody disclosure is rare, and to its credit.

Why C. It is custodial — your funds pass through the operator during the swap, so this is not "non-custodial" in the atomic sense — and it is new (© 2025-26, no web-archive history) with an opaque operator (no named team, no public source, no Tor mirror). What keeps it a *confident* C rather than a wary one is that the custodial risk is structurally tiny: you pay cents-to-a-few-dollars for gas you immediately spend, never parking real value. No-KYC, XMR-native, transparent on price. It climbs toward B- on a clean curator test-order and a track record.
