Solana ID

Solana ID was an on-chain identity and reputation platform built on Solana. The team shut it down in September 2026, citing an unresolved cold-start problem in its two-sided marketplace model.

What Solana ID Did

Solana ID let users aggregate wallets across multiple blockchains and blend that on-chain history with off-chain data feeds to generate a single portable reputation score it called a SOLID score. The score served as a credentialing layer: partner dApps could query a user's SOLID score to gate airdrops, early access, discounts, and loyalty rewards without seeing raw personal data. The privacy architecture used zero-knowledge proofs to verify claims about a user's on-chain activity without exposing the underlying wallet addresses or transaction history to third parties.

The $SOLID token powered a Data-2-Earn loop. When a verifier queried a user's data through the protocol, half the protocol revenue accrued to users who had consented to share that data, paid in $SOLID. Users could also stake $SOLID to underwrite their own reputation, creating a slashing-style penalty for anyone attempting to game their score.

Milestones

The project received a Solana Foundation instant grant and was backed by Mina Protocol and Superteam. It entered the Jupiter LFG Launchpad community vote in its second round and participated in the Colosseum Arena Renaissance hackathon. At peak, the team reported more than 10,000 active users. Integrations included the Adrena perpetuals exchange, the SP3ND Amazon-linked spending card, and the KAST payment app.

Why It Failed

In the team's own accounting, Solana ID was a classic two-sided marketplace that could not bootstrap both sides fast enough. Without a sufficient volume of projects running active data-query campaigns, users had no reward flow. Without a large enough base of active, scored users, projects saw limited reason to run campaigns. The team concluded that the bottleneck was structural and could not be resolved in time to reach the liquidity threshold where both sides would self-sustain.

Shutdown Details

The team announced in September 2026 that the Solana ID Hub, API, and Display Network would go offline at the end of the month. User data will be deleted by the end of 2026; the project's email lists will also be deleted unless users opt in to a successor newsletter.

On the token side, the team burned its entire company treasury allocation of $SOLID, representing 73.78% of total supply, according to the project's own announcement. Liquidity pools were locked rather than drained, leaving $SOLID tradeable on-chain after the application layer disappears. The team noted it is open to acquisition offers on the brand and technology.

The shutdown announcement included an explicit scam warning: Solana ID will never ask users to connect a wallet to claim $SOLID tokens.
