Encode submission
This endpoint accepts an EncodeSubmissionRequest, which internally is a UserTransactionRequestInner (and optionally secondary signers) encoded as JSON, validates the request format, and then returns that request encoded in BCS. The client can then use this to create a transaction signature to be used in a SubmitTransactionRequest, which it then passes to the /transactions POST endpoint.
To be clear, this endpoint makes it possible to submit transaction requests to the API from languages that do not have library support for BCS. If you are using an SDK that has BCS support, such as the official Rust, TypeScript, or Python SDKs, you do not need to use this endpoint.
To sign a message using the response from this endpoint:
- Decode the hex encoded string in the response to bytes.
- Sign the bytes to create the signature.
- Use that as the signature field in something like Ed25519Signature, which you then use to build a TransactionSignature.

Body
Request to encode a submission
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.
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.

An enum of the possible transaction payloads
Secondary signer accounts of the request for Multi-agent
Response
All bytes (Vec<u8>) 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.
