Particle Network Docs - Chain Abstraction & Universal Accounts

After broadcasting a transaction with sendTransaction(), the SDK will return a detailed object containing its execution status, fee breakdowns, token flows, and analytics. Below is a breakdown of the key fields within this object:

Top-Level Fields

Field	Description
`transactionId`	Unique ID of the transaction (used to query status or activity details)
`mode`	Network mode, typically `"mainnet"` or `"testnet"`
`sender` / `receiver`	Address that initiated and received the transaction (usually same)
`type`	Transaction type (e.g. `"universal"`)
`status`	Execution status code (internal enum)
`tag`	Transaction tag (e.g., `"buy"` or `"swap"`)
`created_at` / `updated_at`	ISO timestamps for lifecycle tracking

fees (Cost Breakdown)

Field	Description
`totals.feeTokenAmountInUSD`	Total fee in USD
`feeTokens[]`	List of tokens used to pay fees, with symbols and USD values
`freeGasFee` / `freeServiceFee`	Whether any component was waived

depositTokens / lendingTokens

Tokens deducted from the user’s account to fund the transaction. Each entry includes:

token.symbol
token.chainId
amount and amountInUSD
Full metadata (decimals, icon, etc.)

tokenChanges (Before/After Effects)

Provides the most useful high-level insight into what changed:

Field	Description
`decr[]`	Tokens deducted from the user (chain, token, amount)
`incr[]`	Tokens received by the user
`swaps[]`	Swap routes (e.g. from USDC to USDT via 1inch)
`tokenBalances[]`	Final post-transaction token balances

Analytics & Valuation

Field	Description
`slippage`	Slippage used for the route (in basis points)
`totalFeeInUSD`	Final USD fee value
`totalDecrAmountInUSD`	Total USD value deducted
`totalIncrAmountInUSD`	Total USD value received
`priceImpact`	Estimated price impact (0 if none)
`minReceiveAmountInUSD`	Minimum expected amount (to be received, post-slippage) in USD
`minReceiveToken`	Token targeted by the buy/swap action

Explorer / Activity Link

You can construct a link to see the activity on UniversalX:

const url = `https://universalx.app/activity/details?id=${transactionId}`;
