Returns the specified transaction. The encoding parameter sets the format of the returned transaction. Can be, "cb58", "hex" or "json". Defaults to "cb58".
The avm.getTx command is used to return a specified transaction. Its encoding parameter determines the returned transaction’s format between:
  • cb58 (default)
  • hex
  • json


txID: string,
encoding: string, //optional
}) -> {
tx: string,
encoding: string,

Request Parameters

  • credentials is a list of this transaction's credentials. Each credential proves that this transaction's creator is allowed to consume one of this transaction's inputs. Each credential is a list of signatures.
  • unsignedTx is the non-signature portion of the transaction.
  • networkID is the ID of the network this transaction happened on. (Avalanche Mainnet is 1.)
  • blockchainID is the ID of the blockchain this transaction happened on. (Avalanche Mainnet X-Chain is 2oYMBNV4eNHyqk2fjjV5nVQLDbtmNJzq5s3qs3Lo6ftnC6FByM.)
  • Each element of outputs is an output (UTXO) of this transaction that is not being exported to another chain.
  • Each element of inputs is an input of this transaction which has not been imported from another chain.
  • Import Transactions have additional fields sourceChain and importedInputs, which specify the blockchain ID that assets are being imported from, and the inputs that are being imported.
  • Export Transactions have additional fields destinationChain and exportedOutputs, which specify the blockchain ID that assets are being exported to, and the UTXOs that are being exported.

Response Parameters

  • assetID: The ID of the asset being transferred. (The Mainnet Avax ID is FvwEAhmxKfeiG8SnEvq42hc6whRyY3EFYAvebMqDNDGCgxN5Z.)
  • fxID: The ID of the FX this output uses.
  • output: The FX-specific contents of this output.
