Ephemeral Rollups SDK

SDK for Private Ephemeral Rollups

Overview

Private Ephemeral Rollups are Ephemeral Rollups that enable fine-grained permission over permissioned accounts in a Trusted Execution Environment with compliance at its heart. Each permission account maintains a list of members with specific flags that determine what actions they can perform.

Key Concepts

Permission Account: A PDA that stores access control rules for a specific account
Members: Addresses granted specific permissions via flags
Flags: Bitmasks that define what a member can do (authority, view logs, view balances, etc.)
Public Permissions: When members are set to None, the permissioned account becomes temporarily visible

Member Flags

Member flags define fine-grained permissions for each member. Flags can be combined using bitwise OR to grant multiple permissions. Flag Descriptions:

AUTHORITY: Allows a member to update and delegate permission settings, add/remove other members, and update member flags.
TX_LOGS: Allows a member to view transaction execution logs.
TX_BALANCES: Allows a member to view account balance changes.
TX_MESSAGE: Allows a member to view transaction message data.
ACCOUNT_SIGNATURES: Allows a member to view account signatures

Ephemeral Permission

EphemeralPermission accounts live entirely on the Ephemeral Rollup and are paid for by the delegated PDA — no base-layer permission account to create, delegate, or commit-and-undelegate. Three CPI ops cover the full lifecycle: Create, Update, Close — all PDA-signed by the data account on the ER, via MagicBlock’s Permission Program ACLseoPoyC3cBqoUtkbjZ4aDrkurZW86v19pXz2XQnp1.

Prerequisite — delegate the data PDA. Only the data account is delegated to the TEE validator (on the base layer, via MagicBlock’s Delegation Program DELeGGvXpWV2fqJUhqcF5ZSYMS4JTLjteaAMARRSaeSh). Once delegated, the PDA signs all three permission ops on the ER using its program seeds and pays the ephemeral permission rent — so it must be pre-funded at initialize time. See Quickstart for the end-to-end flow.

These public validators are supported for development. Make sure to add the specific ER validator in your delegation instruction:

Create Ephemeral Permission

Initialize a new EphemeralPermission account on the ER with initial members and the privacy flag. Idempotent — skip if it already exists.

Update Ephemeral Permission

Toggle the privacy flag, or add / remove / re-flag members. Updates take effect immediately on the ER.

Close Ephemeral Permission

Close the EphemeralPermission account on the ER and refund the rent to the data PDA when the permission is no longer needed.

Ephemeral Permission Operations

1. Create Ephemeral Permission
2. Update Ephemeral Permission
3. Close Ephemeral Permission

Initialize a new EphemeralPermission account on the ER via CreateEphemeralPermissionCpi. Payer = the delegated data PDA, which signs with its program seeds and covers the rent from the lamports pre-funded at initialize time.

Use Cases:

Tear down access control once private execution is finished

⬆️ Back to Top

Reference implementations: private-counter/anchor (Anchor) and private-counter/pinocchio.

Best Practices

Authority Management: Always assign AUTHORITY_FLAG to at least one trusted member
Least Privilege: Grant only necessary flags to each member
Real-time Updates: Permissions can be updated in real-time on Private Ephemeral Rollup without undelegating, allowing dynamic access control adjustments
Cleanup: Undelegate and close unused permission accounts to free SOL

Security Considerations

Signer Validation: Only members with AUTHORITY_FLAG or program with permissioned account can authorize changes
Public Accounts: Setting members to None makes the account publicly visible
Default Authority: By default, the owner of the permissioned account is added as permission authority to members of permission account.
Empty Member List: If members field is set to empty list, the permissioned account is fully restricted and private. Only the owner of permissioned account can modify the permission.
Access Auditing: Use member flags to audit and control access
