Aptos RPC Endpoint

Flat-rate Aptos RPC provider and Aptos RPC node access: free tier, no KYC, HTTP.

Aptos is a high-throughput Layer 1 built by former Meta (Diem) engineers, using the Move language and a parallel execution engine (Block-STM). It targets low, predictable latency with sub-second finality and is designed to scale transaction processing across many cores.

About Aptos

Aptos launched mainnet in October 2022. It uses an AptosBFT (Jolteon-based) proof-of-stake consensus and the Block-STM parallel executor, which optimistically runs transactions concurrently and re-executes only on conflict — extracting parallelism without requiring developers to declare dependencies upfront.

Smart contracts are written in Move, a resource-oriented language focused on safe asset handling. Aptos emphasizes upgradeable on-chain modules, a flexible account model with key rotation, and tooling aimed at consumer-scale apps. Developers interact via the Aptos REST API and Move-based SDKs rather than EVM tooling.

Common Use Cases on Aptos

• High-throughput consumer and gaming apps
• DeFi needing fast, predictable finality
• On-chain assets with safe Move resource semantics
• Accounts with native key rotation and flexible auth
• Payments and stablecoin settlement

Aptos Ecosystem

Aptos hosts DEXes and DeFi such as PancakeSwap (Aptos deployment), Thala, LiquidSwap, and Aries Markets, plus a growing NFT and gaming scene. The Aptos Foundation and Aptos Labs maintain the core protocol.
