System Overview

SwapBlok is composed of four integrated protocol layers, accessed through a non-custodial embedded wallet:

┌─────────────────────────────────────────────────────────────────────┐
│  LAYER 1: EXTERNAL CHAINS                                           │
│  Ethereum · Solana · Bitcoin · Tron                                 │
│  2MPC dWallet vaults (ika.xyz): user key + network key              │
└──────────────────────────┬──────────────────────────────────────────┘
                           │  Merkle proofs (permissionless relayers)
┌──────────────────────────▼──────────────────────────────────────────┐
│  LAYER 2: SB CHAIN (IMMUTABLE LEDGER)                               │
│  RDPoS Consensus · Wrapped Asset Minting/Burning · Bridge Module    │
└──────────────────────────┬──────────────────────────────────────────┘

└──────────────────────────┬──────────────────────────────────────────┘
                           │
┌──────────────────────────▼──────────────────────────────────────────┐
│  LAYER 4: INCENTIVE LAYER                                           │
│  SBT Token · LP Rewards · Witness Rewards · Governance              │
└─────────────────────────────────────────────────────────────────────┘

All four layers are non-custodial, transparent, and permanently recorded on SB Chain.

Users interact with all four layers through the SwapBlok Wallet, a non-custodial embedded key management system powered by dfns.io (Section 6). The wallet provides a hardware-secured, seed-phrase-free interface to SB Chain while preserving complete user sovereignty over private keys. For cross-chain bridge operations, users additionally connect their external chain wallet (MetaMask, Phantom, or equivalent) for the source-chain signing step.
