❗️OFAC Screening

As part of our compliance requirements, any API requests made to a sanctioned address will be automatically blocked. This screening applies to all write operations made through our APIs, including but not limited to:

• Sending transactions
• Staking actions
• Smart contract interactions

🚧

Read-only requests that do not involve written actions to the blockchain will not be affected.

We recommend that you ensure your applications do not interact with any addresses included on any sanctions lists. If you have questions or need support, please contact us.

🆕 Ethereum Staking API updates

• Now supporting the Hoodi testnet.
• Included gasEstimate in withdrawal responses for both full exits and partial withdrawals, helping users anticipate transaction costs.

🟣 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.

• 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.

🚧 Batch insert support for Solana withdrawal intents

Refactored StoreSolanaWithdrawalIntent to support batch insertion of large numbers of withdrawal intents. Intents are now grouped (e.g., 1,000 per batch) and inserted in bulk to improve performance and efficiency.

🚀 Improvement on Staking Endpoint

signed-voluntary-exit endpoint now accepts both lowercase and uppercase validator addresses for ownership validation.

✅ Staking POL via the BD app

Improved handling of Solana withdrawal intents to ensure accurate status updates for stake accounts, including better validation and processing of pending and executed intents.

Login to the Blockdaemon app to try it out and refer to the doc here.

✅ Staking POL via the BD app

Resolved an issue where users withdrawing Polygon via the BD app received MATIC tokens instead of POL.

⚙️ Ethereum Endpoint Update

We've updated the description of Ethereum - Generate a Signed Voluntary Exit Message as user can now generate the exit message before the validator is activated, as long as it has a status on-chain. Note that the message cannot be broadcast in this state.

✅ Updated API Endpoint

• [Polygon] Fix the contract address for bootstrapping intent on the mainnet.
• Learn more in the Post Bootstrapping Intent.
