Solana Foundation caps its validator delegation program at 12 months and 100 validators

The Solana Foundation has put an expiration date on its help. Under updated rules for its Validator Delegation Program, membership now lasts a maximum of 12 months.

The program will also support no more than 100 validators at a time. Any validator that attracts more than 300,000 SOL in external stake has to leave.

What changed in the delegation program

The new guidelines took effect on November 6, 2026. They apply to the Solana Foundation Delegation Program, usually shortened to SFDP.

Validators are the computers that process transactions and keep the Solana network running. They earn rewards based on how much SOL, the network’s native token, is staked with them.

New validators face a classic chicken-and-egg problem. Nobody wants to stake with an unproven operator, and operators can’t prove themselves without stake. The SFDP has tried to solve that by lending Foundation stake to promising newcomers.

The revised rules set three hard limits:

• Time: participation is capped at 12 months.
• Size: the program will delegate to a maximum of 100 validators.
• Success: validators must exit once their external stake exceeds 300,000 SOL.

Existing participants who already break these limits won’t be cut loose overnight. They will be retired in weekly tranches. They are also allowed to apply again under the new criteria.

The fine print on costs and compliance

The program covers vote costs during a participant’s first 12 months, on a tapering schedule. Coverage starts at 100% and steps down to 0% after that period.

Participants also have to meet a broader set of requirements. Validators can charge a maximum 5% commission, the cut they take from staking rewards before passing the rest to delegators.

They must also meet software requirements. And they face limits on concentration in data centers and ASNs.

An ASN, or autonomous system number, roughly identifies the network provider a server connects through. If too many validators run through the same provider or the same building, a single outage could knock out a big chunk of the network. The concentration limits are meant to spread that risk around.

A shrinking footprint, by design

As of Epoch 1077, 337 validators were participating in the SFDP. Those validators held a combined Foundation stake of approximately 23.74 million SOL. That represents about 5% of total staked SOL on the network.

At the program’s inception, the Foundation’s share was nearly 44%.

The new 100-validator cap sits well below that current headcount of 337. That gap helps explain the weekly tranche approach. Retiring participants gradually avoids a sudden drop in stake for a large group of validators at once.

What this means for validators and the network

The core message is that the SFDP is a launchpad, not a permanent home. The findings describe the changes as reinforcing that mission and signaling a shift toward a more market-driven validator ecosystem.

The 300,000 SOL exit threshold creates a clean dividing line. Validators above it have shown they can stand on their own. Keeping them in the program would tie up Foundation stake that could instead support newer entrants.

The data center and ASN concentration limits stay in place, and the reapplication path remains open for retired participants.
