SimpleHash

SimpleHash is no longer operating as a standalone service. It was a developer API for NFT and token data across many blockchains, Solana included. The crypto wallet [[PROJECT:853]] (Phantom) acquired it in February 2025, and the public API shut down on March 27, 2025.

Status

Phantom announced the acquisition on February 26, 2025, and SimpleHash confirmed it on X the next day. That post is the last one on the account. According to Phantom, SimpleHash had already told its customers that the existing service would be discontinued as the team moved into Phantom. The Block reported that the price was not disclosed.

Migration guides from Alchemy and Goldsky put the end of the service at March 27, 2025. As of September 2026, simplehash.com and its blog pages return HTTP 404 errors, and the documentation site sits behind a password.

What SimpleHash did

SimpleHash was founded in 2022. According to The Block, it raised $500,000 from investors including Y Combinator and Coinbase Ventures. Its product was an indexed data API, so wallets, marketplaces, games and analytics tools could get token and NFT data without running their own indexers.

Phantom and The Block both say it supported more than 80 blockchains and handled thousands of requests per second. Phantom described it as a token data platform with real-time prices, historical data and instant on-chain updates. The API also returned NFT metadata, media and marketplace activity. Alchemy's migration guide lists four areas that customers had to replace: NFT data, token balances and metadata, historical market data, and wallet balance queries across multiple chains. Goldsky called token balance and transfer tracking SimpleHash's core strength. It also noted that some customers took data through a Kafka streaming feed.

SimpleHash also gave tokens spam-detection scores to help flag malicious and fraudulent assets. Phantom named this feature as one reason for the acquisition, since spam tokens and NFTs are a persistent problem for wallet users.

Solana support

Solana was one of SimpleHash's supported chains, with a dedicated Solana NFT API page on its site. SimpleHash announced general availability for Solana compressed NFTs on mainnet, devnet and testnet. The API returned their metadata, media, transaction history and pricing in the same format as regular Solana NFTs. It also showed each NFT's compression status, Merkle root and leaf index. This let developers work with compressed NFTs without parsing the underlying state-compression data themselves.

Acquisition by Phantom

SimpleHash was Phantom's third acquisition in about eight months, after Bitski in May 2024 and the security firm Blowfish in November 2024. Phantom said it bought SimpleHash to make token data more reliable in its wallet: accurate real-time prices, NFT metadata, marketplace activity and spam filtering. The SimpleHash team, led by co-founder Olly Wilson, joined Phantom. Wilson said that joining Phantom would let the team "scale our technology and bring even more powerful Token and NFT data to millions of users."

The technology now runs inside Phantom rather than as a public API. Former SimpleHash customers were directed to other data providers, and several infrastructure companies published migration guides for them.
