EIP Fun Weekly #91: Enhancing On-Chain Asset Management, Margin Token, Signature Verification
A weekly resource exploring the latest EIPs, ERCs, key updates in the Ethereum protocol.
Welcome to read the 91th issue of EIP Fun Weekly. Let's take a look at what happened in the EIP community last week.
Meeting Updates
Ethereum All Core Developers Execution Call #208
Pectra Upgrade
Pectra Mainnet Activation Date: Tentatively set for April 30, 2025, with final releases due between April 10-14.
Pectra Testing on Hoodi: Testing continues but delayed due to validator deposit backlogs; no critical issues found so far.
Client Configurations Before Upgrades: Proposed EIP 7910 to ensure smooth upgrade deployments by detailing client configurations, still under review.
EOF in Fusaka: Complete EOF proposal moves forward despite opposition, with updates to documentation to reflect it.
Other Information
PeerDAS Updates: Sunnyside Labs working to accelerate PeerDAS implementation, with discussions on how to integrate it into client layers.
Fusaka Scope: Broad support for including EIP 7883 in Fusaka; no new EIPs to be added until PeerDAS and EOF are ready.
History Expiry: Pushed back May 1 deadline for activating history expiry on mainnet until after Pectra upgrade, with focus on Sepolia testnet first.
Protocol Research Calls: New call series starting April 2, 2025, to discuss Ethereum’s long-term future.
Weekly EIP & ERC Highlights
ERC-7908: HD Wallet in Treasury Management
Proposes a standardized method for managing institutional assets on-chain using HD wallets with hierarchical key paths for secure key generation and departmental isolation.
Purpose: Enhance on-chain treasury management by enabling secure, hierarchical key management and departmental isolation, supporting asset security and transaction efficiency in multi-chain environments.
Key Benefits:
Provides secure hierarchical key management for institutional assets.
Ensures departmental isolation and permission control.
Supports multi-chain environments for efficient asset management.
Aligns with BIP-44 standards for deterministic key generation.
Key Components:
Hierarchical deterministic (HD) key paths for asset management.
Entity and department-specific key isolation.
Secure private key generation using a standardized derivation path.
ERC-7909: Margin Token Wrapper
Defines a wrapper contract that converts any ERC-20, ERC-721, or ERC-1155 token into a lockable "margin token" for use as collateral across DEXs.
Purpose: Enhance interoperability and enable the use of any token as collateral by wrapping it into a lockable margin token, allowing for secure and flexible margin management across different DEX protocols.
Key Benefits:
Converts any ERC-20, ERC-721, or ERC-1155 token into a lockable margin token.
Enables cross-protocol interoperability for decentralized margin trading.
Provides a unified wrapper contract for multiple token standards.
Supports token locking with expiration to avoid infinite locking.
Key Components:
MarginTokenWrapper contract: Implements core functionalities such as minting, approving, locking, unlocking, and liquidating tokens.
ApproveLock and PermitLock: Allows for the approval of locking tokens with specific limits and expiration times.
Lock and Unlock operations: Manage locked assets as collateral for margin trading.
Burn function: Enables the conversion of unlocked tokens back into their original form.
ERC-7913: Signature Verifiers
Proposes a standard for verifying signatures from keys without Ethereum addresses, such as those from other cryptographic curves, hardware devices, or email-based systems.
Purpose: Enable the verification of signatures from keys without Ethereum addresses by using verifier contracts, facilitating account abstraction and the integration of diverse cryptographic methods for signing.
Key Benefits:
Extends signature verification to keys without Ethereum addresses, such as non-Ethereum cryptographic curves (e.g., secp256r1, RSA), hardware devices, or emails.
Reduces the need for deploying multiple ERC-1271-compatible contracts by using a small number of verifier contracts.
Facilitates account abstraction and social recovery by decoupling signers from traditional Ethereum addresses.
Backward compatible with Externally Owned Accounts (EOA) and ERC-1271 contracts.
Key Components:
Keys: Represented as
bytesobjects of arbitrary length, such as public keys from P256 or RSA.Verifiers: Smart contracts that handle signature verification for a specific key type, identified by their Ethereum address.
Signer Identification: Signers are identified by a
(verifier, key)pair rather than a fixed on-chain address.
Other EIPs and ERCs:
ERC-7914: An Interface for Transfer From Native
ERC-7920: Composite EIP-712 Signatures
EIP-7921: Skip `JUMPDEST` immediate argument check
