Babylon RPC Endpoint

Fast, flat-rate Babylon RPC node provider — 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.

Network: Babylon

Type: Non-EVM

Slug: babylon

Native token: BABY (Babylon)

Block time: ~6 seconds

Finality: Single-block deterministic finality via CometBFT once a block is committed; Bitcoin timestamping additionally anchors checkpoints to Bitcoin.

Mainnet: April 10, 2025

Category: Cosmos SDK Bitcoin staking chain (CometBFT)

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

Note: Babylon uses its own RPC methods. Refer to the official Babylon documentation for available methods.

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.

Frequently Asked Questions: Babylon

How is Babylon queried?

Babylon exposes CometBFT RPC plus Cosmos SDK REST and gRPC endpoints, including modules covering BTC staking, finality providers, and Bitcoin checkpointing.

Does Babylon have an EVM chain ID?

No. Babylon Genesis is a non-EVM Cosmos SDK chain and uses a Cosmos chain-id string (bbn-1) rather than an EVM chain ID.

What are the BABY token decimals?

BABY uses 6 decimals; the base denomination is ubbn, where 1 BABY = 1,000,000 ubbn.

Is staked Bitcoin bridged or wrapped?

No. Bitcoin is staked through self-custodial scripts directly on the Bitcoin network; it is not bridged or converted into a wrapped token.
