getTransactionByHash

This method obtains the transaction by hash of the chains passed as parameters.

Inputs

Name	Type	Required	Description
`input`	[ChainHashInput!]!	Yes	List of transaction queries with chain name and transaction hash.

`ChainHashInput` Fields

Name	Type	Required	Description
`chain`	String!	Yes	Chain ID.
`hash`	String!	Yes	Transaction hash.

chain

Type: Chain!

Allowed Values: A chain ID from the list of supported chains.

[!WARNING] This query requires archive data. While it works for all listed supported chains, some chains might fail for older transactions. These limited chains are marked in the supported chains list.

hash

Type: String!

Allowed Values: Any transaction hash as string.

Response

Returns a list of ChainTransactionDetails objects.

`ChainTransactionDetails`

Field	Type	Description
`chain`	String!	The blockchain name.
`hash`	String	The transaction hash.
`transaction`	TransactionDetails	The detailed transaction information (type varies by chain).
`error`	String	Error message if fetching failed.

`TransactionDetails` (Union)

The transaction field is a union type and can be one of the following types depending on the blockchain:

EVMTransactionDetails (Ethereum-compatible chains)
SolanaTransactionDetails (Solana)
TendermintTransactionDetails (Cosmos and Tendermint chains)
