Babylon RPC Endpoint

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

Babylon Genesis is a Cosmos SDK chain that coordinates Bitcoin staking, letting BTC holders stake natively to provide security to proof-of-stake networks without bridging or wrapping. It uses Bitcoin timestamping and slashable self-custodial staking scripts. SwiftNodes provides Babylon RPC across load-balanced nodes.

About Babylon

Babylon's Genesis layer-1 launched on April 10, 2025, alongside the BABY token, built with the Cosmos SDK and CometBFT (Tendermint) consensus. BTC stakers lock bitcoin in self-custodial scripts on the Bitcoin network that can be slashed for misbehavior, with no bridging or wrapped BTC involved.

The chain coordinates Bitcoin Staking and Bitcoin timestamping for secured PoS networks. BABY is used for staking to validators, fees, and governance, while staked BTC contributes to security.

Common Use Cases on Babylon

• Native Bitcoin staking
• Shared security for PoS chains
• Bitcoin timestamping
• BTCfi yield
• Validator staking and governance

Bridging to Babylon

Babylon is IBC-enabled and connects to the Cosmos ecosystem over IBC; Bitcoin staking is done with self-custodial scripts on Bitcoin rather than a bridge.
