Solana devs are shipping a big efficiency gain next month with zero breaking changes. P-token, coming to mainnet in April, is a drop-in replacement for the SPL token program. The leaner implementation unlocks 19x more efficient transfers, freeing up ~10% of block space. It also adds a new batch instruction. Each CPI call into the token program carries a fixed base cost: if a protocol needs to do five transfers, that’s five separate calls. Batch bundles them into one, so programs pay that cost once regardless of how many transfers are inside.​​​​​​​​​​​​​​​​ Every SPL token transaction on the network is about to get cheaper and more efficient. No migration, no opt-in required. helius.dev/blog/solana-p-tok…
