The Solana Foundation Delegation Program (SFDP) is the Foundation-run bootstrapping program that provides new and ongoing validators with residual Foundation delegation, stake matching against external delegations, and tapered vote transaction cost coverage in exchange for meeting ongoing performance and infrastructure compliance thresholds. It is the primary path by which a new Solana validator reaches profitability before accumulating sufficient external delegated stake to cover its operating costs.
The program is operated by the Solana Foundation; the canonical reference is solana.org/delegation-criteria. Participation is conditional on meeting performance, commission, and infrastructure thresholds reviewed each epoch.
What SFDP provides
SFDP distributes Foundation-controlled stake across qualifying participants in two distinct mechanisms:
Residual delegation
A baseline allocation of Foundation stake distributed across all qualifying participants. This component is independent of the validator's external stake; it provides a floor of delegation that sustains the validator while it acquires direct delegators. As of epoch 971, residual delegation per qualifying validator is in the range of ~15,000 SOL (per Solana Foundation delegation dashboard).
Stake matching
The Foundation matches external (non-Foundation) stake delegated to a participating validator at a 1:1 ratio, capped at 100,000 SOL of matched stake. Matching mechanics:
- Validator with 0 SOL external stake: 0 SOL matched, receives only residual delegation.
- Validator with 50,000 SOL external stake: 50,000 SOL matched (1:1), plus residual.
- Validator with 100,000 SOL external stake: 100,000 SOL matched (1:1, at the cap), plus residual.
- Validator with 100,000-1,000,000 SOL external stake: matching remains at the 100,000 SOL cap; no further matching is added.
- Validator with >1,000,000 SOL external stake: no Foundation delegation, neither matching nor residual.
Stakers should note these are the current figures. Outdated third-party content still circulates "0.5× stake matching up to 50,000 SOL" — that figure is obsolete; the current parameter is 1:1 up to 100,000 SOL per the Foundation's published delegation criteria.
Vote transaction cost coverage
Solana validators currently pay approximately 1.1 SOL per day in vote transaction fees (per Helius validator economics primer at epoch 971), eliminated only when Alpenglow deploys. SFDP covers these costs on a tapered schedule, expressed in epochs since the validator's program enrollment:
| Epoch range from enrollment | Vote cost coverage |
|---|---|
| 0-45 | 100% |
| 46-90 | 75% |
| 91-135 | 50% |
| 136-180 | 25% |
| 181+ | 0% |
180 epochs is approximately 12 months at the current ~2-day epoch cadence. After month 12, the validator absorbs its own vote costs in full. The taper schedule is intentional: SFDP bootstraps a validator through its early operating period when external stake is below break-even, then withdraws subsidy as the validator either reaches self-sustaining stake or exits.
Performance thresholds
A participating validator must meet the following per-epoch:
- Vote credits at or above 97% of cluster average (mainnet); ≥85% in 5 of last 10 epochs (testnet).
- Skip rate within network average + 5 percentage points. At a network median of 0.14% (per Stakewiz, epoch 971), this places the SFDP-acceptable upper bound at approximately 5.14%.
- Base commission at or below 5%.
- Jito MEV commission at or below 10%.
- Metric reporting in 8 of the last 10 epochs (testnet eligibility prerequisite).
A validator failing a threshold loses SFDP eligibility for the affected epoch; reinstatement requires meeting the threshold for at least 5 of the most recent 10 epochs.
Infrastructure thresholds (effective May 1, 2026)
These thresholds entered force at May 1, 2026 and apply to all SFDP participants:
- ASN concentration below 25% of network stake — the validator's hosting ASN may not carry more than a quarter of network stake.
- Data center concentration at or below 15% — the validator's specific data center may not carry more than 15% of network stake.
- Transaction processing rules — FIFO or priority-fee-ordered scheduling within 50ms windows; shreds released every 50ms or per coalesced erasure batch; no TPU censorship; no TPU delay beyond 50ms. These govern the validator's TPU (Transaction Processing Unit) behavior during leader slots.
These rules are why TeraSwitch's AS20326 — currently ~29% of network stake (per Validators.app, May 2026) — is a material flag for SFDP-participating validators hosted there. Operators in AS20326 must migrate or accept SFDP ineligibility once the threshold takes effect. Live enforcement state of these rules is tracked in the SFDP 2026 Rules Tracker.
Offboarding policy ("1-on, 3-off")
The Foundation cycles SFDP participants: validators may be retired from the program after 18 months on mainnet if their external stake remains below 5,000 SOL. The shorthand is "1-on, 3-off" — one in, three rotated out. This is a cycling mechanism, not a performance penalty; a validator can be retired despite meeting all performance thresholds simply by failing to grow external stake to the 5,000 SOL minimum within the window.
The 5,000 SOL threshold replaces older "1,000 SOL" figures still circulating in third-party content; the actual current threshold is 5,000 SOL per the Foundation's published criteria.
Status terminology
When citing a validator's SFDP relationship, use precise terms:
- In SFDP — currently receiving Foundation delegation and vote-cost coverage.
- Eligible but not enrolled — meets the criteria but has not been onboarded.
- Never enrolled — has not been admitted to the program.
- Offboarded — was previously in SFDP, has been removed under the cycling policy or for unrecoverable threshold failure.
These are distinct states; conflating them obscures what the validator's actual situation is.
What SFDP is not
- Not a Foundation endorsement. SFDP is a stake bootstrapping program with objective thresholds; participation is not an editorial seal of approval.
- Not the same as Wiz Score. A validator can hold a high Wiz Score and be outside SFDP, or vice versa. The two scoring systems are independent.
- Not the same as stake pool inclusion. Marinade SAM, Jito Stake Pool, and SolBlaze each have their own selection criteria distinct from SFDP.
