Solana Raises New Stake Account Minimum to 1 SOL After SIMD-0490 Update Now

Solana raises new stake account minimum to 1 SOL after SIMD-0490, while Everstake launches Blockspace access.

Solana has raised the minimum stake delegation for new stake accounts to 1 SOL. The network-level change, known as SIMD-0490, went live on June 18, 2026.

The rule applies only to new stake accounts created after the update. Existing Solana delegations remain unchanged, so current stakers do not need to take action.

The change comes as Solana moves toward lower rent costs across the network. Without a minimum floor, new stake accounts could become very cheap to create.

At the same time, Everstake has introduced Blockspace for Solana transaction access. The product is aimed at validators, traders, searchers, and DeFi protocols.

Solana Adds 1 SOL Rule for New Stake Accounts

Solana now requires at least 1 SOL for every new stake delegation. This rule affects only new stake accounts opened after SIMD-0490 became active.

The change is linked to Solana’s move toward reduced rent costs. Lower rent could make account creation cheaper across the network.

However, very low account costs may create a spam risk. A 1 SOL minimum adds a basic cost barrier for new delegations.

The update does not change existing stake accounts. Users with active delegations can continue staking without adding more SOL.

Existing Solana Stakers Remain Unaffected

Current Solana stakers do not need to adjust their existing delegations. The new minimum applies only to accounts created after June 18, 2026.

This detail is important for users who already delegated SOL. Their current stake accounts remain valid under the previous setup.

However, users opening new stake accounts must follow the new requirement. Any new delegation below 1 SOL will not meet the updated minimum.

The rule may also affect users who split funds across many small accounts. New staking activity may now become more structured across wallets and platforms.

Everstake Launches Blockspace for Solana Access

Everstake also introduced Blockspace, a marketplace for Solana’s inbound transaction path. The product connects validator infrastructure with users seeking better transaction access.

Many failed Solana transactions do not reach a block. Some are dropped at the RPC level or during the QUIC handshake.

Other transactions may fail at the scheduler or after the blockhash window closes. These points can affect traders, searchers, and DeFi protocols during busy periods.

Blockspace presents the inbound path as a two-sided marketplace with four products. 

Validators supply infrastructure, while network users buy aggregated access through the platform.
