FAQ
What is SIMD-0437?
A Solana improvement document that reduces lamports_per_byte from 6,960 to 696 in five feature-gated steps: 6,333, 5,080, 2,575, 1,322 and 696. The proposal says each next step is taken only after a risk analysis.
Does it change accounts I already have?
Existing accounts keep the lamports they hold. The proposal notes they are only allowed to reduce their balance to the new, lower minimum — for example by withdrawing the difference where the program allows it.
When is the next step?
The SIMD sets no dates. Each step is activated separately by feature gate. This page reads the rate from the network every hour and shows which step it matches.
Why do articles still say a token account costs 0.00203928 SOL?
That was (128 + 165) × 6,960 lamports before the first step. Once a step is active, a new token account needs less.
