Submit transaction

This endpoint accepts transaction submissions in two formats.

To submit a transaction as JSON, you must submit a SubmitTransactionRequest. To build this request, do the following:

Encode the transaction as BCS. If you are using a language that has native BCS support, make sure of that library. If not, you may take advantage of /transactions/encode_submission. When using this endpoint, make sure you trust the node you're talking to, as it is possible they could manipulate your request.
Sign the encoded transaction and use it to create a TransactionSignature.
Submit the request. Make sure to use the "application/json" Content-Type.

To submit a transaction as BCS, you must submit a SignedTransaction encoded as BCS. See SignedTransaction in types/src/transaction/mod.rs. Make sure to use the application/x.aptos.signed_transaction+bcs Content-Type.

Body

sender*Address (string (hex))

A hex encoded 32 byte Aptos account address.

This is represented in a string as a 64 character hex string, sometimes shortened by stripping leading 0s, and adding a 0x.

For example, address 0x0000000000000000000000000000000000000000000000000000000000000001 is represented as 0x1.

Example: "0x88fbd33f54e1126269769780feb24480428179f552e2313fbe571b72e62a1ca1 "

sequence_number*U64 (string (uint64))

A string containing a 64-bit unsigned integer.

We represent u64 values as a string to ensure compatibility with languages such as JavaScript that do not parse u64s in JSON natively.

Example: "32425224034"

max_gas_amount*U64 (string (uint64))

A string containing a 64-bit unsigned integer.

We represent u64 values as a string to ensure compatibility with languages such as JavaScript that do not parse u64s in JSON natively.

Example: "32425224034"

gas_unit_price*U64 (string (uint64))

A string containing a 64-bit unsigned integer.

We represent u64 values as a string to ensure compatibility with languages such as JavaScript that do not parse u64s in JSON natively.

Example: "32425224034"

expiration_timestamp_secs*U64 (string (uint64))

A string containing a 64-bit unsigned integer.

We represent u64 values as a string to ensure compatibility with languages such as JavaScript that do not parse u64s in JSON natively.

Example: "32425224034"

payload*TransactionPayload (object)

An enum of the possible transaction payloads

type*string

Example: "entry_function_payload"

function*EntryFunctionId (string)

Entry function id is string representation of a entry function defined on-chain.

Format: {address}::{module name}::{function name}

Both module name and function name are case-sensitive.

Example: "0x1::aptos_coin::transfer"

type_arguments*array of MoveType (string)

Type arguments of the function

itemsMoveType (string)

String representation of an on-chain Move type tag that is exposed in transaction payload. Values: - bool - u8 - u16 - u32 - u64 - u128 - u256 - address - signer - vector: vector<{non-reference MoveTypeId}> - struct: {address}::{module_name}::{struct_name}::<{generic types}>

Vector type value examples:
  - `vector<u8>`
  - `vector<vector<u64>>`
  - `vector<0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>>`

Struct type value examples:
  - `0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>
  - `0x1::account::Account`

Note:
  1. Empty chars should be ignored when comparing 2 struct tag ids.
  2. When used in an URL path, should be encoded by url-encoding (AKA percent-encoding).

arguments*array of any

Arguments of the function

itemsany

signature*TransactionSignature (object)

An enum representing the different transaction signatures available

type*string

Example: "ed25519_signature"

public_key*HexEncodedBytes (string (hex))

All bytes (Vec) data is represented as hex-encoded string prefixed with 0x and fulfilled with two hex digits per byte.

Unlike the Address type, HexEncodedBytes will not trim any zeros.

Example: "0x88fbd33f54e1126269769780feb24480428179f552e2313fbe571b72e62a1ca1 "

signature*HexEncodedBytes (string (hex))

All bytes (Vec) data is represented as hex-encoded string prefixed with 0x and fulfilled with two hex digits per byte.

Unlike the Address type, HexEncodedBytes will not trim any zeros.

Example: "0x88fbd33f54e1126269769780feb24480428179f552e2313fbe571b72e62a1ca1 "
