Unified liquidity and cross-chain swaps are V2 features — not yet live. V1 supports smart contracts, deposits, and withdrawals on each chain independently. Cross-chain swapping (BTC ↔ ZEC ↔ DOGE) is coming in V2.
What is Unified Liquidity?
Today, BTC, ZEC, and DOGE each live in separate ecosystems. Swapping between them requires:
- Sell your BTC on a centralized exchange
- Receive ZEC
- Withdraw to your wallet
This involves trusting a third party, paying high fees, and waiting.
NEXUS V2 eliminates this. All three assets are accessible from a single protocol. You express what you want and solvers (automated market participants) compete to give you the best rate — no exchange account needed.
V1 (Current) — Independent Chain Operations
Each chain works fully today, just independently:
| Chain | Deposits | Withdrawals | Smart Contracts |
|---|
| Bitcoin | ✅ | ✅ | ✅ |
| Zcash | ✅ (t-addr) | ✅ (t-addr) | ✅ |
| Dogecoin | ✅ | ✅ | ✅ |
| BTC ↔ ZEC swaps | ❌ V2 | — | — |
| BTC ↔ DOGE swaps | ❌ V2 | — | — |
| ZEC ↔ DOGE swaps | ❌ V2 | — | — |
V2 — Intent Exchange
V2 introduces intent exchange: declare what you want, solvers compete to fill it.
You declare: "Swap 1 BTC for at least 50,000 DOGE"
↓
Solver network sees your intent
↓
Solvers compete to find the best route and rate
↓
Best solver executes the swap across chains
↓
You receive DOGE; solver keeps a small fee
Why Intent Exchange?
| Problem | How Intent Exchange Solves It |
|---|
| Front-running | Intents are committed before execution — no one can trade ahead of you |
| Slippage | Price is locked when you create the intent |
| Counterparty risk | All-or-nothing: you either get the minimum promised or nothing |
| Complexity | You just say what you want — solvers handle routing |
V2 AMM Pools
Alongside intent exchange, V2 introduces on-chain liquidity pools that anyone can provide liquidity to:
BTC/ZEC Pool
BTC/DOGE Pool
ZEC/DOGE Pool
Any Token/vSAT Pool (NEP-20 tokens)
- Earn a share of swap fees (0.3% per swap)
- Deep liquidity = better prices for everyone
- Withdraw any time
Concentrated Liquidity (V3-style)
NEXUS AMM V3 lets liquidity providers choose a price range to concentrate their liquidity in. Liquidity in range earns more fees than spread across all prices — more capital-efficient.
V2 Swap Preview (Code, Not Yet Live)
// This is what V2 swap will look like — not available yet
const intent = await client.createSwapIntent({
fromChain: 'bitcoin',
toChain: 'dogecoin',
fromAmount: '100000000', // 1 BTC in satoshis
minToAmount: '50000000000', // Minimum 500 DOGE (won't execute below this)
recipient: 'DQkw...', // Your Dogecoin address
deadline: Math.floor(Date.now() / 1000) + 3600 // Expires in 1 hour
});
// Wait for a solver to fill your intent
const result = await client.waitForIntentFulfillment(intent.id);
console.log('Received DOGE:', result.amountOut);
