L2Savings.eth 🦇🔊

How much in fees have you saved by using Ethereum L2s? Special thanks to @DCbuild3r for the ENS name!

New update: Say hi to @base!

[L2Savings.eth 🦇🔊 @L2Savings]

@0xgunboats @Optimism It would be really nice if a good RPC provider sponsored, just saying...

[L2Savings.eth 🦇🔊 @L2Savings]

@0xgunboats @Optimism Haha, wow. Let me know if it loads or not. L2Savings uses batch request but still it has to wait for around ~300 ms between each request and repeat rate-limited requests.

[L2Savings.eth 🦇🔊 @L2Savings]

L2Savings has been updated!

- Improved accuracy for Arbitrum savings using eth_feeHistory calls
- Experimental support for @LineaBuild
- A better UI! Now you can see the savings for any address without connecting a wallet

L2Savings now supports Arbitrum Nitro!

@hamidrezamehr12 I love Starkex, but it's hard to calculate savings.
- They don't have an explorer
- No way to get all transactions of an address
- Multiple modes, rollup, volition, validium, each with different fee(s), making it hard to calculate

Congrats to 0xA28F....F941C for having the highest savings on Optimism (that I know of).

This bot has saved over 1036 ETHER by using Optimism, 2511x cheaper than mainnet.

Their cheapest transaction was 3584x cheaper.

The new update is live! Now L2Savings batches RPC requests to calculate your savings faster!

Please report on Github if you encounter any bugs.

How is better accuracy achieved?

- L2Savings now uses eth_getTransactionReceipt to extract the L1 gas price during the time of transaction. Although this approach takes slightly more time to calculate, it's much more accurate

[L2Savings.eth 🦇🔊 @L2Savings]

L2Savings has been updated to have 100% accurate Optimism Savings 🎉

The new update also includes:
- Less UI Bugs & Mobile support
- Better Arbitrum & ZkSync estimations
- A FAQ page on calculations

L2Savings relied on Poloniex for historical eth price data to calculate fees paid in USD. The new version will be rolling out soon, with some extra features. Stay tuned!

[Lefteris Karapetsas @LefterisJP]

Hey @Poloniex, what the heck are you guys smoking?

You are doing:
- 10 hours maintenance
- roll out a new trading system
- roll out a new API
- immediately deprecate the old API without living any grace period for consumers to implement support for your new API?!??!

Wtf?

[L2Savings.eth 🦇🔊 @L2Savings]

L2Savings will be down until Poloniex API is back up again / replaced.

The issue should be "almost" fixed. A thread on why the exact fees spent can't be calculated and have to be estimated 1/n

[Daniel Fetz @danftz]

@litocoen @L2Savings Something seems wrong with it.

It overstates most of my L2 transaction costs by the factor of 7. For example, this one transaction did cost me 0.00006 ETH and @L2Savings says it cost me 0.0005 ETH. Quite a dramatic difference.

[L2Savings.eth 🦇🔊 @L2Savings]

@etherscan In conclusion, the data would be more accurate for Optimism if:
- @etherscan API on Optimism provided fees paid in ether, which means the exact L1 gas price can be extracted, or
- If there was an API that provided accurate historical gas price data (for each hour/minute)
