Blockchain Integration
Vortum uses ICP's Chain Fusion technology for bridgeless multi-chain integration.
Supported Blockchains
| Blockchain | Status | Assets |
|---|---|---|
| Bitcoin | Live | BTC |
| Solana | Live | SOL, SPL tokens |
| ICP | Live | ICP, ckBTC, ckETH, ICRC tokens |
| Ethereum | Planned | ETH, ERC-20 |
How Chain Fusion Works
Unlike traditional bridges that lock assets on one chain and mint wrapped tokens on another, Chain Fusion enables direct interaction with multiple blockchains from a single smart contract.
Key Benefits:
- No wrapped tokens or bridge contracts
- Assets remain on native chains
- Single unified balance across chains
- Reduced smart contract risk
Deposit Flow
Withdrawal Flow
Bitcoin
Bitcoin integration uses ckBTC and threshold ECDSA signatures.
Features:
- Native BTC deposits (no wrapping required)
- SegWit addresses (lower fees)
- 6 confirmation requirement for security
- Dynamic fee estimation
Deposit Process:
- User receives a unique BTC address
- User sends BTC to the address
- After 6 confirmations, balance is credited
- Funds are available for trading
Solana
Solana integration uses HTTPS outcalls and Ed25519 threshold signatures.
Features:
- Fast finality (~400ms)
- SOL and SPL token support
- Priority fees during congestion
- Automatic token account creation
Deposit Process:
- User receives a unique Solana address
- User sends SOL or SPL tokens
- Transaction confirmed in seconds
- Balance immediately available
ICP Native
Native ICP integration with ICRC token standards.
Features:
- Instant finality
- ICRC-1/ICRC-2 token support
- No external dependencies
- ckBTC, ckETH support
Security
All blockchain interactions use threshold cryptography:
- No single point of failure - Keys are distributed across ICP nodes
- Decentralized signing - Transactions require consensus
- Auditable - All operations recorded on-chain
