Overview

On May 7, 2025, the major Pectra upgrade to the Ethereum network was carried out that brought the following benefits for clients who use ETH or SSV validators.

• Enhanced efficiency and security with validators that can hold more than 32 ETH (up to 2048 ETH)
• Several validators can now be consolidated into one
• Auto-compounded rewards
• Partial top-ups and withdrawals from validators

P2P.ORG has introduced a series of improvements to its staking APIs, enabling clients to take full advantage of the new validator capabilities. These changes include support for both Ethereum and SSV-based validators.

Note that most of these features require updating the validator’s withdrawal credential type from either 0x00 or 0x01 to a new 0x02-type withdrawal credential.

SSV Validator Support under Pectra

P2P.ORG has extended its SSV staking API to fully support the capabilities introduced with the Ethereum Pectra upgrade. This ensures that clients using the SSV network can benefit from the same validator enhancements as native Ethereum staking users.

All SSV staking methods now align with the Ethereum Staking API to offer consistent workflows, regardless of your validator backend. Key updates:

1. Unified flow. Most operations, except validator setup, use the same API methods for both Ethereum and SSV validators
2. Simplified validator setup via the 3.1 Smart Contract. SSV validator creation flow now supports 0x02 withdrawal credentials

Backward Compatibility

All changes are backward compatible with the current 0x01 validator flow and allow seamless migration to the 0x02 type of withdrawal credentials for enhanced functionality.

• Clients currently using the 0x01 validator setup can continue without changes, as well as create new 0x01 validators as before
• All existing methods remain supported
• New functionality is exposed via new API methods or optional parameters in existing methods

This ensures a seamless upgrade path without breaking changes.
