**Introducing SIMD-0266: The Efficient Token Program Upgrade Set to Transform Solana Token Operations**
Proposed by Anza, the developer behind Solana’s dominant node software client Agave, the SIMD-0266: Efficient Token Program update promises to bring radical improvements to token operations on Solana (SOL) blockchains. Compared to the existing SPL architecture, this upgrade could reduce resource usage by an astonishing 200 times.
### 98% Less Resource Usage with SIMD-0266
SIMD-0266 is poised to become one of the most crucial Solana improvement proposals of 2025 and is expected to revolutionize the efficiency of token creation on Solana. According to Anza, a leading Solana infrastructure company and the proposal’s author, this update could achieve up to a 98% economy in compute resource usage.
Currently, approximately 10% of block compute units are consumed by token program instructions. By replacing the SPL standard with the new p-token, nearly 12% of block space can be freed up for other transactions. This enhancement, in turn, will significantly boost Solana’s effective transaction throughput.
### New Instructions for Complex DeFi Operations
The upgrade introduces new instruction types such as **Batch** and **UnwrapLamports**, designed to reduce compute usage for common DeFi patterns. These instructions enable multiple token operations per cross-program invocation (CPI) and eliminate the need for temporary native accounts. As a result, programs can execute complex flows far more efficiently than before.
### 100% Backward Compatibility
One of the key benefits of the p-token introduction is its complete backward compatibility. This means it will be a seamless, drop-in upgrade requiring no changes to existing SPL tokens. The backward-compatible design paves the way for larger resource allocations for new blocks, ultimately contributing to a faster and better-performing Solana blockchain.

### Looking Ahead: Solana’s Alpenglow Upgrade in Early 2026
The Solana community has warmly welcomed the SIMD-0266 design, recognizing its potential to unlock new opportunities in decentralized finance (DeFi). Meanwhile, Solana is also progressing toward its much-anticipated **Alpenglow upgrade**, scheduled for early 2026.
The Alpenglow upgrade will retire the current proof of history (PoH) mechanism and replace it with a more efficient consensus scheme. This change is expected to bring massive improvements in security, performance, and speed to the Solana blockchain, marking a significant milestone for the network’s future.
