Canto RPC Endpoint

Fast, flat-rate Canto RPC node provider — free tier, no KYC, HTTP & WebSocket.

Canto is an EVM-compatible Layer 1 built with the Cosmos SDK and CometBFT (Tendermint), focused on providing DeFi primitives such as a DEX, lending market, and the NOTE unit of account as free public infrastructure. SwiftNodes provides Canto mainnet RPC over HTTP and WebSocket.

About Canto

Canto launched in August 2022 with no presale, foundation, or venture backing. It uses Tendermint-based proof-of-stake consensus, giving fast block times and instant BFT finality, and exposes an Ethereum-compatible EVM.

Canto's design centers on Free Public Infrastructure (FPI): the Canto DEX, the Canto Lending Market, and the NOTE cryptodollar are built into the chain as public goods. The team explored migrating to a Polygon CDK Layer 2 in 2023 but reversed course in 2024, remaining a Cosmos-based Layer 1.

Common Use Cases on Canto

• Free public DeFi (DEX and lending)
• NOTE stablecoin / unit of account
• Permissionless smart contracts
• Cosmos IBC transfers
• Real-world-asset experimentation

Canto Ecosystem

Built around the native Canto DEX, Canto Lending Market, and NOTE; the broader ecosystem includes third-party DeFi protocols deployed on the EVM.
