Scroll Gas Tracker

Scroll is a zkEVM rollup built for bytecode-level equivalence with Ethereum (a Type 2 zkEVM): existing Solidity contracts deploy unmodified, and every batch of transactions is proven correct with a zero-knowledge validity proof rather than waiting out a week-long fraud-proof challenge window like an Optimistic rollup. Gas on Scroll is paid in ETH, the same asset used for gas on Ethereum mainnet — not SCR, Scroll's own governance token.

A Scroll transaction fee is two charges added together. The L2 execution fee is simply gas used times the gas price you (or your wallet) set — closer to Ethereum's pre-2021 pricing than to a live congestion-driven base fee, and it sits low because Scroll's block capacity usually outpaces demand. The L1 data fee, sometimes called the rollup fee, is your share of publishing a compressed batch of Scroll transactions back to Ethereum as an EIP-4844 blob, a switch Scroll made with its July 2024 Curie upgrade.

The formula behind that L1 data fee changed again with the December 2025 Galileo upgrade: fees are now priced with a linear term based on your transaction's compressed size plus a quadratic term that only kicks in hard for outsized transactions. Galileo replaced an earlier flat "penalty over threshold" model that attackers had learned to game by sending oversized transactions to inflate the L1 blob fees other users pay.

Scroll's own execution fee rarely moves much — most of what changes your quote traces back to Ethereum's blob market or the size of the transaction itself.

• Ethereum blob market demand — The L1 data fee is priced off Ethereum's live blob base fee. A busy stretch on mainnet raises what every rollup, Scroll included, pays to post data, even with nothing happening on Scroll itself.
• Transaction size, since Galileo — Larger, calldata-heavy transactions — contract deployments, complex swaps — now pay a quadratically scaling penalty on top of the linear base charge, so an oversized transaction costs disproportionately more than a plain transfer.
• Network congestion on Scroll — Scroll's sequencer typically runs with spare capacity, so the L2 execution fee has room to absorb normal traffic without rising; sustained demand spikes can still push it up.
• Prover throughput — Batches need a validity proof generated and verified on Ethereum before they finalize. Proving capacity affects how quickly, not how much, a batch settles, which can widen the gap between submitting a transaction and seeing it final.

Most Scroll confusion comes from either the token or the timing.

• No SCR token needed for gas — Every Scroll transaction fee is paid in ETH. SCR, Scroll's token launched in October 2024, is for governance — you don't need to hold or acquire it to transact.
• Withdrawals don't take a week — Scroll's validity proofs typically finalize on Ethereum within hours, not the roughly seven-day fraud-proof window Optimistic rollups like Arbitrum, Optimism, or Base use for their canonical bridges. A third-party bridge can still be faster for a fee, but Scroll's own bridge isn't held to that longer delay.
• Oversized transactions cost more than they used to — Since the Galileo upgrade, a transaction with unusually large calldata — some NFT mints, batched contract calls — can cost noticeably more than gas used alone would suggest. The quadratic size penalty is doing that, not a spike in network demand.
• Pick the right network when withdrawing from an exchange — Sending funds to a Scroll address requires selecting “Scroll” as the network, not “Ethereum” or generic “ERC-20”. The address format looks identical across EVM chains, so a withdrawal on the wrong network still sends, just to a chain you can't see the funds on without bridging.
