Proposed by Anza, a developer of Solana’s dominant node software client Agave, the SIMD-0266: Efficient Token Program update is expected to bring a radical improvement to token operations on Solana. 
SOLUSD blockchains. Compared to the existing SPL architecture, it could reduce resource utilization by 200 times.
98% Less Resource Usage: Learn about SIMD-0266: Efficient Token Program Upgrade
SIMD-0266: Efficient Token Program, one of the most crucial Solana improvement proposals of 2025, is expected to be a breakthrough in the efficiency of token creation on Solana. SOLUSD. As Anza, Solana infrastructure company and author of the proposal, explains, the savings in IT resources could reach 98%.
1/ SIMD-0266: Efficient Token Program, written by @0x_febo, proposes to replace the current SPL token program with a new version optimized for calculation called p-token. The upgrade will reduce Token CU program usage by up to 98%. Here’s how it works 🧵 pic.twitter.com/5ASETDEYqu
Currently, 10% of block computing units are spent on symbolic program instructions. Designed to replace the SPL standard, p-token will free up almost 12% of block space for other transactions, which, in turn, will increase Solana’s effective transaction throughput.
Namely, new instruction types will be added to handle more complex DeFi structures, thereby saving blockchain computational unit expenses:
New instructions such as Batch and UnwrapLamports further reduce computation for common DeFi models, enabling multiple token operations per CPI and removing the need for temporary native accounts. Programs can now execute complex flows much more efficiently.
Featuring 100% backwards compatibility, the introduction of the p-token will be an immediate upgrade: no changes will be expected for existing SPL tokens.
This, in turn, will pave the way for larger resource allocations for new blocks, with a faster and more capable Solana. SOLUSD as the final objective.
Solana SOLUSD set for crucial Alpenglow upgrade in early 2026
Solana SOLUSD community enthusiasts welcome the new design, emphasizing that it will open up new opportunities for decentralized finance here.
As covered by U.Today previously, Solana SOLUSD is getting closer to its Alpenglow upgrade. Scheduled for early 2026, it is expected to remove historical evidence and replace it with a more effective consensus system.
The security, performance and speed of Solana SOLUSD blockchain will experience considerable growth.
