HyperEVM has implemented two major architectural upgrades in its latest testnet update—Dual-Block Architecture for improved transaction efficiency and Sender-Agnostic Token Transfers for expanded functionality. The changes aim to optimize block speed, transaction scalability, and developer experience on the Hyperliquid Layer 1 blockchain.
Background
- HyperEVM, an Ethereum Virtual Machine (EVM) environment integrated within Hyperliquid’s Layer 1 blockchain, enables developers to run Ethereum-compatible smart contracts with enhanced speed and cost-efficiency.
- Co-founder Jeff announced the latest testnet upgrade on Discord, revealing two significant changes to improve the system’s overall performance and flexibility.
1. Dual-Block Architecture
HyperEVM now splits throughput between:
Small blocks that process transactions at a faster rate for quick confirmations.
Large blocks that operate at a slower rate to accommodate high-value and complex transactions.
The update also introduces separate mempools for each block type, ensuring smoother transaction processing while maintaining on-chain execution integrity.
Initial testnet parameters:
Fast blocks: 2-second duration, 1M gas limit.
Slow blocks: 1-minute duration, 30M gas limit.
2. Sender-Agnostic Token Transfers
Previously, HYPE token transfers were limited to externally owned accounts (EOAs).
Now, a system contract replaces the previous transfer method, allowing smart contracts to initiate HYPE transfers.
The update maintains backward compatibility while adding a minor gas fee for logging transfers.
Why should you pay attention?
- Scalability & Performance: The dual-block system removes the tradeoff between speed and transaction size, benefiting both everyday users and developers.
- Improved Smart Contract Functionality: The new sender-agnostic token transfer system allows automated transactions, expanding DeFi capabilities.
- Testnet Reset & Black Market Response: EVM balances were reset to counter unauthorized black market activities, reinforcing fair use of testnet tokens.
Who said what?
- Hyperliquid Co-Founder Jeff, on testnet optimizations:
“Users want faster blocks for quick confirmations, while builders need larger blocks for complex contract deployments. Instead of a tradeoff, this system allows both.”
- On the token transfer upgrade:
“This change enables smart contracts to send HYPE while maintaining backward compatibility for EOAs.”
- On the testnet balance reset:
“All EVM balances were reset due to previously announced black-market testnet HYPE activity.”
Zooming out
- HyperEVM continues evolving as an Ethereum-compatible blockchain while leveraging Hyperliquid’s high-speed Layer 1 network.
- The dual-block system could influence future EVM architectures, balancing speed and transaction size without compromise.
