Supported Blockchains
BlockVault works with 13 mainnet blockchains out of the box. All of them are derived from the same recovery phrase, so adding a new chain doesn't require a new backup — you already have it.
At a glance
| Blockchain | Family | Native asset | Notable for |
|---|---|---|---|
| Bitcoin | Bitcoin | BTC | The original. Store of value. |
| Counterparty | Bitcoin (layer) | XCP | Issuing tokens and NFTs secured by Bitcoin. |
| Ethereum | EVM | ETH | The hub of DeFi, stablecoins and ERC-20 tokens. |
| Polygon | EVM | MATIC | Cheap and fast Ethereum-compatible payments. |
| BNB Chain | EVM | BNB | Large DEX ecosystem, low fees. |
| Base | EVM | ETH | Coinbase's L2, growing consumer apps. |
| Arbitrum | EVM | ETH | Leading Ethereum L2 for DeFi. |
| Optimism | EVM | ETH | OP Stack L2, public-goods focus. |
| Tempo | EVM | — (no native gas) | Payments L1; fees paid in stablecoins. |
| Solana | Solana | SOL | High-throughput chain for trading and NFTs. |
| dYdX | Cosmos | DYDX | Decentralized perpetual futures. |
| Osmosis | Cosmos | OSMO | Cross-Cosmos DEX. |
| Noble | Cosmos | USDC | Native USDC issuance for the Cosmos ecosystem. |
No testnets. BlockVault is mainnet only.
What you can do on each chain
Every chain supports:
- Receive — generate addresses and QR codes.
- Send — native asset and tokens.
- Balances — native and token balances, refreshed automatically.
- History — recent on-chain activity.
- Assets — view tokens you hold.
- Web3 — sign messages and transactions for dApps.
On EVM chains there is also a DeFi module: curated strategies for lending, staking and farming.
A note on Tempo
Tempo is unusual: it's an EVM-compatible Layer 1 with no native gas token. Instead, fees are paid in approved TIP-20 stablecoins like USDC.e, USDT0, EURC.e, pathUSD or frxUSD.
| Setting | Value |
|---|---|
| Chain ID | 4217 |
| RPC | https://rpc.tempo.xyz |
| Explorer | https://explore.tempo.xyz |
| Derivation | m/44'/60'/0'/0/0 (same as Ethereum) |
| Gas | Paid in stablecoins, no native token |
Your Ethereum address works as your Tempo address — same private key, just a different network.
A note on Counterparty
Counterparty is a token-issuance protocol that lives on top of Bitcoin. Your Bitcoin address is your Counterparty address, and Counterparty transactions are real Bitcoin transactions that carry extra data.
That means Counterparty inherits Bitcoin's security and any token you hold there is provably tied to a Bitcoin UTXO. BlockVault supports browsing assets, sending tokens, and interacting with on-chain dispensers and the DEX.
Adding more chains
The wallet is designed so new chains can be plugged in over time. If a chain matters to enough people, it's a candidate to be added.
