Transaction Types

When requesting a route, the API returns a transactionType field that determines how the transaction should be constructed and submitted on-chain. The type depends on the source chain and whether the route involves DEX swaps.

DEPOSIT_ADDRESS_CALLDATA

• Source chains: All EVMs (except Hedera), XRPL, Solana

• Conditions: Direct route (no DEX swaps)

• Example routes: Ethereum:USDC → Base:ETH, Solana:SOL → Arbitrum:USDC, XRPL:RLUSD → XRPL:XRP

Code examples:

Route	API	SDK
EVM → EVM	evmToEVMSwap	evmToEVMSwap
Solana → EVM	solanaToEVM_Swap	—
XRPL → EVM	xrplToArbitrumSwap	xrplToArbitrumSwap
EVM → XRPL	baseToXrplSwap	baseToXrplSwap
Stellar → EVM	stellarToEVMSwap	stellarToEVMSwap

DEPOSIT_ADDRESS_WITH_SIGNATURE

• Source chains: Hedera

• Conditions: Direct route (no DEX swaps)

• Example routes: Hedera:HBAR → Arbitrum:USDC, Hedera:USDC → Arbitrum:USDC

ON_CHAIN_EXECUTION_WITH_SIGNATURE

• Source chains: Hedera

• Conditions: Pre-hook (DEX swap) + Coral step

• Example route: Hedera:SAUCE → Arbitrum:USDC

ON_CHAIN_EXECUTION

• Source chains: All EVMs (except Hedera), Cosmos

• Conditions: DEX swap as first action (Single-chain DEX swap, Pre-hook (DEX swap) + Coral step, DEX swap + Axelar bridge step)

• Example routes: Arbitrum:USDC → Arbitrum:ETH, Arbitrum:USDT → Base:ETH, Osmosis:USDC → Base:USDC

Code examples:

Route	API	SDK
EVM pre-hook → EVM	evmPrehooktoEVM	evmPrehooktoEVM
Cosmos → EVM	cosmostoEVMSwap	—
Cosmos → EVM (post-hook)	CosmostoEVMPostHook	—

CHAINFLIP_DEPOSIT_ADDRESS

• Source chains: Solana, Bitcoin

• Conditions: Chainflip as first step

• Example routes: Bitcoin:BTC → Arbitrum:ETH, Solana:SOL → Arbitrum:ETH
