What is Ankr?

Ankr is a Web3 infrastructure provider operating a distributed remote procedure call (RPC) network, scaling services, and multichain staking protocols across more than 70 blockchains. Its bare-metal node architecture handles approximately 8 billion daily RPC queries across 30 global regions, maintaining an average response time of 56 milliseconds and 99.99% uptime.

Founding and backing

Ankr was founded in 2017. The project secured early capital through seed and private token sales in 2017 and 2018, raising $15 million and $12 million from investors including Pantera Capital, Bixin Ventures, DHVC, and NGC Ventures. In August 2022, Binance Labs made a strategic investment in the protocol to expand its RPC endpoints and scaling suites.

Core services and developer access

The platform provides public, premium, and enterprise-grade RPC endpoints through its Web3 API, alongside an Advanced API that supports simultaneous queries across 19 mainnet and 7 testnet chains via JavaScript and Python SDKs. Beyond node routing, Ankr provides rollup and sidechain engineering, alongside delegated and liquid staking contracts across nine tokens, including Ethereum, BNB, Avalanche, and Polkadot. In October 2026, Ankr introduced its x402 service on Monad. Autonomous AI agents can query blockchain data through the service and pay per request in USDC without manual account registration or static API keys.

Pricing and resource tiers

Developers can access public RPC lanes for free or subscribe to a Freemium tier providing 200 million API credits each month. Paid monthly plans range from 500 to 3,000 USD, delivering 20% more API credits than pay-as-you-go pricing, with credits pegged to the US dollar and expiring every 30 days. Custom infrastructure solutions are negotiated under enterprise agreements.

Security track record and operational risks

Ankr's staking contracts have undergone third-party audits by Beosin in 2022 and Veridise in 2023. However, the protocol has experienced significant security breaches. In December 2022, a former team member compromised the deployer private key through supply-chain vulnerabilities, minting trillions of unauthorized aBNBc tokens and collapsing the token's market price. In August 2026, an exploit involving the ankrFLOW smart contract resulted in an estimated $9.3 million loss from the external More Markets protocol.

Pros and cons

Pros

  • Free tier includes 200 million API credits every month
  • Node network spans over 70 supported blockchains
  • Low average RPC response time of 56 milliseconds
  • Pay-per-request model allows autonomous access for AI agents in USDC

Cons

  • Compromise of the deployer private key enabled unauthorized aBNBc minting and caused a more than 99% price crash in December 2022
  • Contract exploit on ankrFLOW led to $9.3M drained in August 2026
  • Monthly plan API credits expire after 30 days and do not roll over

Ankr provides distributed high-speed RPC endpoints across 70+ chains, but past smart contract exploits are a material consideration for its liquid staking products.

Founded in 2017, Ankr operates a distributed bare-metal node network spanning over 30 global regions. The platform handles roughly 8 billion daily RPC requests, offering developers low-latency connectivity with an advertised 56 ms average response time and 99.99% uptime SLA on its Web3 API suite. Backed by investors including Binance Labs and Pantera Capital, it has expanded from raw compute infrastructure into node infrastructure, custom rollup engineering, and liquid staking.

Its primary operational strength is broad multichain coverage. Ankr supports more than 70 distinct blockchains, ranging from established EVM networks like Ethereum and Polygon to Sui, Monad, and Robinhood Chain. Developers can use a free tier providing 200 million API credits monthly alongside public RPC lanes. For high-volume applications, paid monthly tiers provide additional API credits, while specialized tooling like Verifiable RPC and the x402 pay-per-request protocol cater to autonomous AI agents needing verifiable chain data without fixed subscriptions.

The main drawback centers on historical security incidents tied to its smart contract infrastructure. In December 2022, an attacker exploited a compromised deployer key to mint 60 trillion unbacked aBNBc tokens, collapsing the asset's price by over 99%. More recently, in August 2026, an exploit involving the ankrFLOW contract led to the loss of approximately $9.3 million from More Markets protocol. While Ankr underwent smart contract audits from firms such as Beosin and Veridise, these incidents highlight risks within its staking protocols.

Ankr suits decentralized application developers seeking cost-effective, low-latency node infrastructure across multiple EVM and non-EVM chains. Teams building high-throughput dApps can take advantage of its distributed bare-metal footprint.

“Not today! Just got the second ANKR Forge Drop. In two months they’ve given me 50,000 ANKR just for holding on the Forge. ANKR is standing out right now compared to my other tokens.”

“So you understand.. and ai knows much more than you do. If they don't connect the token with the company there is no value in the token. The company it's doing well but because the coin is disconnected from the company that's why is not increasing in price.”

“Ankr AMA It’s obvious a lot of people here are wondering where this project is headed. Many of us have been around for years, and while we try to stay optimistic, it’s getting harder when there’s so little communication or real updates from the team. This isn’t a knock on Sergio.”
