Staking API (2025-03-06)

🟣 Ethereum Staking API Updates

1. Pectra Upgrade Support

Pectra is the next major Ethereum hard fork, combining two key upgrades: The execution layer upgrade (Prague) & The consensus layer upgrade (Electra).

• Increased Validator Limit: Raise maximum effective balance per validator from 32 ETH to 2,048 ETH for auto-compounding rewards.
• Faster Deposits: Validator activation delays now average ~45 minutes, improving onboarding speed.
• Independent Withdrawals: Users can now withdraw staking rewards or exit without needing validator operator action.
• Reduced Slashing Penalties: Slashing penalties reduced 128x for improved validator safety.

We’ve added full support for Pectra in the Ethereum Staking API and Staking In App flow.

2. Updated Stake Flow

• Mainnet, Holesky, and Hoodi network options
• Validator types 0x01 and 0x02
• Flexible validator sizing from 32–2,048 ETH per validator

3. Withdrawals Intent Endpoints

Introduced new /withdrawals-intent endpoints to the Ethereum Staking API, allowing users to define withdrawal parameters before staking. These intents help manage reward withdrawals and exits more effectively:

• Partial withdrawals – withdraw staking rewards while keeping the validator active
• Full exits – exit the validator and withdraw all funds

🔵 Polkadot Staking API Updates

Added a new /bond-extra endpoint, enabling users to bond more tokens to an existing stash account. This increases the DOT stake without the need to re-nominate or unbond.
