Transforms a generic transaction request into a blockchain-specific transaction with
all necessary parameters populated for the target network.
What this endpoint does:
- Validates transaction data against the specified blockchain network
- Converts generic amounts to blockchain-native units (e.g., 0.1 SUI → 100000000 MIST)
- Calculates and populates network-specific parameters (gas price, gas budget, nonce)
- Transforms generic transaction types to chain-specific types (TRANSFER → SUI_TRANSFER)
- Returns a structured transaction request ready for confirmation and execution
Supported transaction types:
- Native transfers: Send blockchain's native currency (ETH, SUI, MATIC, etc.)
- Token transfers: Send ERC-20 or equivalent tokens
- NFT transfers: Transfer ERC-721/ERC-1155 or equivalent NFTs
- Contract execution: Call smart contract functions
- Multi-transfers: Batch multiple operations (Hedera only)
