Retrieves the execution status of a quote by its quote ID as well as transaction hashes for user operations

Get quote status

Execution status of the quote. The status progresses through different stages:
- PENDING: Operation has been submitted but processing has not yet begun
- IN_PROGRESS: Currently processing the execution steps of the operation
- EXECUTED: Transaction has been executed on the destination chain but origin chain operations may still be pending
- COMPLETED: All operations on both origin and destination chains have been completed successfully
- REFUNDED: Operation failed at some step, causing the whole operation to be refunded
- FAILED: All steps of the operation failed

Cross Origin Resource Sharing

Predicts the address for a new OneBalance smart account based on the provided EVM-compatible signer addresses (session and admin). This allows you to determine the smart account's on-chain address before its actual deployment. This predicted address serves as a primary identifier for the user within the OneBalance ecosystem.

Predict smart account address

Request a quote for transferring or swapping assets.

Get quote

Prepares the necessary data structure for executing one or more contract calls on a target chain. This endpoint helps construct the appropriate user operation, handles token allowance requirements, and generates a signed quote ready for execution.

Prepare call quote

Gets a quote for arbitrary contract call operations on a specific chain. This endpoint handles the execution of pre-signed user operations with typed data signatures, supporting interactions with smart contracts.

Get call quote

Execute a previously generated quote to transfer funds.

Execute quote

Retrieves the transaction history for an address, including the transaction type and token details.

Get transaction history

Retrieves a list of all aggregated assets currently supported and enabled on the OneBalance platform. Each aggregated asset includes details such as its unique ID, symbol, name, decimals, and the underlying individual assets (chain-specific tokens) that constitute it, identified by their CAIP-19 asset types.


List aggregated assets

Fetches the aggregated balance of all supported assets for a given smart account address, with an option to filter by specific `assetId`s.
