🟣 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.
