Introduction

Krypton is a sovereign, EVM-compatible proof-of-stake Layer-1. It runs Berachain's beacon-kit (a CometBFT consensus client, instant single-slot finality) driving bera-reth (a Reth fork, revm EVM) over the standard Engine API, with a sovereign app-layer suite of staking / governance / slashing / reward contracts.

It is EVM-equivalent at the execution layer (it runs revm, the same EVM as a Reth mainnet node), not a from-scratch reimplementation — standard Solidity/Vyper and Foundry work unchanged. The chain differs from Ethereum at the consensus layer (BFT instant finality, not probabilistic) and in a few governed economics (e.g. the base fee is redirected, not burned).

The node types

Role	What it does	Guide
Validator	Signs/proposes blocks; holds (or threshold-signs) the consensus key	Validator
RPC / full node (L5)	Non-validating; serves eth_getProof to edge/light clients + dapps	RPC node
Seed / bootnode	Peer discovery for the network	Seed
Edge node	A verifying light client (not a full node) — turnkey on a Raspberry Pi, also runs on other hardware	Edge node

Supporting services: a block explorer (Blockscout at kryscan.com), monitoring (Prometheus + Grafana), key management (Horcrux threshold signing), and secrets (Vault / KMS).

Networks

Network	Chain ID	Hex	Status
Testnet	473374	0x7391e	the public network these guides target
Mainnet	47337	0xb8e9	reuses the same artifacts; gated on external audit + testnet soak
Devnet	80087	—	local Kurtosis / ephemeral

See Networks & chain IDs for the canonical allocation.
