NEXUS-Dogecoin launches after Zcash. Zcash is the first live chain. Dogecoin support is fully designed and implemented — this page documents what Dogecoin integration will look like at launch.
Overview
NEXUS-Dogecoin brings smart contracts to Dogecoin. Dogecoin’s 1-minute block time makes it the fastest deposit experience in the NEXUS ecosystem — your deposit is confirmed in ~6 minutes vs ~60 minutes for Bitcoin.
Why Dogecoin?
- Fastest confirmations: ~3 minutes (3 blocks × 1 min)
- Lowest fees: ideal for micro-payments and small amounts
- Large, active community
- Real proof-of-work security
How Trust Works on Dogecoin
NEXUS-Dogecoin uses the same trustless security model as Bitcoin:
- ZK-STARK proofs — Every state update has a cryptographic proof of correctness
- Economic bonds — Operators post collateral that is forfeited if they cheat
- Fraud proofs — Anyone can challenge incorrect state with on-chain verification
- Escape hatch — You can always withdraw unilaterally after the timelock

Deposit Guide
1. Get your vault address
const vault = await client.getVaultAddress(20160); // 20,160-block timelock (~2 weeks)
console.log('Send DOGE to:', vault.vaultAddress);
dogecoin-cli sendtoaddress <VAULT_ADDRESS> 1000
const balance = await client.getBalance();
// Balance shown in DOGE units (vDOGE)
Withdrawal Guide
// Returns: { success, txid, status, path, confirmed? }
const result = await client.withdrawFunds(
'D...', // your Dogecoin destination address
100000, // amount
);
console.log('Withdrawal txid:', result.txid);
Confirmation Time Comparison
| Chain | Block Time | Confirmations | Total Wait |

| Bitcoin | 10 min | 6 | ~60 min |
Use Cases Where Dogecoin Shines
Micro-payments
Low fees and fast blocks make DOGE perfect for small transactions — tipping, gaming rewards, micro-payments under $1.
Quick arbitrage
Need to react to a price discrepancy? Dogecoin deposits confirm in 6 minutes.
High-frequency DeFi
More block time = more state commitment opportunities = more granular price tracking.
Meme token launches
Deploy a token, set up liquidity, go. The community is there.
// Deploy a meme token on NEXUS using DOGE
const token = await client.deployContract(memeTokenWasm, [
'ShiNexus', // name
'SHINEX', // symbol
18, // decimals
'1000000000000' // total supply
]);
console.log('Token address:', token.contractId);
