It activates eleven Ethereum Improvement Proposals, the largest set ever deployed in a single upgrade. Long-time Ethereum contributor [Pooja Ranjan](https://www.youtube.com/live/NbxaCZYtW-I?si=jCo8-JWw2KGVdwFN) counts Pectra as the network’s 19th upgrade [since 2015](https://ethereum.org/en/history/) and the 3rd hard fork since The Merge. > Pectra is live on Ethereum mainnet! > > \- Smart account wallet UX features now active > \- L2 scaling data storage blobs increased by 2x > \- Validator UX improvements live > > Community members will continue to monitor for any issues over the next 24 hours. > > — Ethereum.org (@ethereum) [May 7, 2025](https://twitter.com/ethereum/status/1920061243966054696?ref_src=twsrc%5Etfw) Pectra combines the separate “Prague” execution-layer changes with the “Electra” consensus-layer changes so that both halves of the protocol move forward together. The path to mainnet wasn't smooth sailing. Early activations on the [Sepolia](https://blog.ethereum.org/2025/03/05/sepolia-pectra-incident) and [Holešky](https://github.com/ethereum/pm/blob/master/Pectra/holesky-postmortem.md#holesky-coordinated-slashings) testnets revealed critical issues. To make absolutely sure the code was ready, core developers spun up a purpose-built [Hoodi](https://blog.ethereum.org/2025/03/18/hoodi-holesky) testnet, where Pectra finalized cleanly, paving the way for the mainnet slot. [![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-17.png)](https://ethereumupgrades.com/) Source: [ethereumupgrades.com](https://ethereumupgrades.com/) The 11 EIPs fall into 3 major categories to improve user experience, streamline staking experience, and support L2 scaling. The rest of the article looks at the headline EIPs in each category and shows where Etherscan surfaces the new data. ### 1) [**EIP-7702 Set Code for EOAs**](https://eips.ethereum.org/EIPS/eip-7702) This upgrade allows you to sign an authorization message that enables your EOA to temporarily adopt the capabilities of a chosen smart contract, opening the door to [better user experience](https://blog.biconomy.io/a-comprehensive-eip-7702-guide-for-apps/#what-can-eip-7702-do) via batched transactions, sponsored gas payments, and permission management. **Where to see it on Etherscan** Pectra introduces a new `Type 4` transaction that carries an `Authorization List`, used when you sign an authorization message. On Etherscan, you can find a list of EIP-7702 Authorizations at [etherscan.io/txnauthlist](https://etherscan.io/txnauthlist). [![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-8.png)](https://etherscan.io/txnauthlist) Source: [Etherscan](https://etherscan.io/txnauthlist) Open any one of the transactions in the list to view details of an authorization in a transaction under the `Authorization List` tab. [![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-9.png)](https://etherscan.io/tx/0x7b9a227b9e40976b44f98acf1320d52e314fdcbc5d55f8e71f6127cc591c9a4d#authorizationlist) Source: [Etherscan](https://etherscan.io/tx/0x7b9a227b9e40976b44f98acf1320d52e314fdcbc5d55f8e71f6127cc591c9a4d#authorizationlist) Here, you'll find: 1. **Authority**: The EOA that signed the authorization message 2. **Delegated Address**: The contract whose code the EOA will run 3. **Nonce**: The EOA's last used nonce 4. **yParity, r, s**: These are components of cryptographic signature that are used to verify the EOA's consent to delegate execution [![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-11.png)](https://etherscan.io/address/0x74Af9a4B5526f9e4f965957D6F660b323A617cd8#authlist7702) Source: [Etherscan](https://etherscan.io/address/0x74Af9a4B5526f9e4f965957D6F660b323A617cd8#authlist7702) The EOA's address page shows you: 1. The address it is currently delegated to (if any), and 2. All the past authorizations signed by this EOA To remove a previous delegation, the wallet simply signs a fresh authorisation whose delegated address is the zero-address (`0x0000000000000000000000000000000000000000`). ![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-18.png) **Important to Note:** - While this new feature makes it much easier for users to transact on Ethereum, it also makes phishing scams easier if users are not careful. As a rule of thumb: - Delegate only to trusted contracts that have been verified and audited by the community - Avoid reusing delegations across different chains, as the same contract address can point to completely different code on each network - Regularly review and revoke outdated delegations to retain control over your address - Wallet providers like [MetaMask](https://x.com/MetaMaskDev/status/1920117837554733502) and others will be slowly rolling out features that support EIP-7702.

Read more on staking-related improvements covered in the [previous article](https://info.etherscan.com/how-pectra-shapes-the-future-of-ethereum-staking/). This EIP introduces the `Consolidation Request Contract` that processes stake consolidation requests from validators. The request requires a `96` byte input with: 1. `source_address`: `Bytes20` 2. `source_pubkey`: `Bytes48` 3. `target_pubkey`: `Bytes48` Up to two consolidation requests are processed per block. The `source` validator exits, and its full balance is credited to the `target` validator after the standard withdrawal delay. **Where to see it on Etherscan** On Etherscan, simply navigate to the [Consolidation Request Contract](https://etherscan.io/address/0x0000bbddc7ce488642fb579f8b00f3a590007251) to inspect any one of the transaction. We'll use this consolidation request transaction as an example: [![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-5.png)](https://etherscan.io/tx/0x1e51fb35eb729b30297223fe881ec396d1fe3d064516a2318de194bd6339a0e4#eventlog) Source: [Etherscan](https://etherscan.io/tx/0x1e51fb35eb729b30297223fe881ec396d1fe3d064516a2318de194bd6339a0e4#eventlog) 1. This is the execution layer (EL) address that submits and pays for the consolidation request 2. This is the validator key whose balance is being withdrawn. The screenshot below shows its balance dropped to 0 after the exit [![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-3.png)](https://beaconscan.com/main/validator/0x8a8c17f7f2cf7a6f89f8750c6031d4423088f7333b58cdb660a537648dfddbd26a6a5cd61e7b5bb8808fdaedd268a162) Source: [BeaconScan](https://beaconscan.com/main/validator/0x8a8c17f7f2cf7a6f89f8750c6031d4423088f7333b58cdb660a537648dfddbd26a6a5cd61e7b5bb8808fdaedd268a162) 3. This is the validator key that receives the transferred stake. The screenshot below confirms the higher effective balance once the consolidation is credited. [![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-6.png)](https://beaconscan.com/main/validator/0xaff5e9f564f4d4848b08688694060645f6c8067497feaaa1a10c0ec0628c3b95682bd8d15085af723c8bfafb8dc2c4cf) Source: [BeaconScan](https://beaconscan.com/main/validator/0xaff5e9f564f4d4848b08688694060645f6c8067497feaaa1a10c0ec0628c3b95682bd8d15085af723c8bfafb8dc2c4cf) To see how many consolidation requests an EL address has made, use Advanced Filter with the `AND` operator. In this example, the address submitted 8 consolidation requests, resulting in a total effective balance of 256 ETH. ![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-7.png) You can monitor validator consolidations via this dashboard: [![](https://info.etherscan.com/pectra-upgrade-whats-new-and-how-to-track-it-on-etherscan/images/2025/05/image-21.png)](https://www.pectra.info/consolidation) Source: [pectra.info](https://www.pectra.info/consolidation) Fun fact: > 🧐PECTRA/MAXEB TIDBIT🧐 > > Consolidating all Ethereum validators into max-size 2048 ETH validators would take at least 19 months due to the 256 ETH per epoch consolidation churn limit. > > — Jrag.eth (@Jrag0x) [May 7, 2025](https://twitter.com/Jrag0x/status/1920093044658807015?ref_src=twsrc%5Etfw) - Read more about EIP-7251: - [https://www.kiln.fi/post/ethereum-pectra-upgrade---everything-you-need-to-know](https://www.kiln.fi/post/ethereum-pectra-upgrade---everything-you-need-to-know) - [https://x.com/nixorokish/status/1909785898893689161](https://x.com/nixorokish/status/1909785898893689161) - [https://notes.ethereum.org/@fradamt/maxeb-consolidation](https://notes.ethereum.org/@fradamt/maxeb-consolidation) ### 3) [**EIP-7691 Blob Throughput Increase**](https://eips.ethereum.org/EIPS/eip-7691) This change doubles the target blobs per block so that rollups have more cheap space for data availability: - Target blobs per block: 3 → 6 - Maximum blobs per block: 6 → 9 More blobs mean L2s can publish twice the data without competing for calldata, keeping transaction fees low even as activity grows. **Where to see it on Etherscan** On Etherscan, visit [etherscan.io/txsBlobs](https://etherscan.io/txsBlobs) to view blobs posted to Ethereum in real time. Alternatively, you can browse [etherscan.io/blocks](https://etherscan.io/blocks) to view the number of blobs in each block.
