Overview

Transfer

Create a transfer transaction:

Rust

NOTE This library has been updated to accept tx data in the form of Borsh-encoded vectors. See ../types/README.md in packages/types for more information on their usage.

// Assume we have a Borsh-encoded message "transfer_msg" and "tx_msg", and "secret" (String):
let Transfer { tx_data } = Transfer::new(transfer_msg)
    .expect("Transfer should instantiate");
let signer = Signer::new(&tx_data);
let transaction = signer.sign(&tx_msg, secret)
    .expect("Should be able to convert to transaction");

let hash = transaction.hash();
let bytes = transaction.bytes();

TypeScript

// Assume we have Borsh-encoded messages "transferMsg" and "txMsg", and secret (string)
const { tx_data } = new Transfer(transferMsg).to_serialized();
const signer = new Signer(tx_data );
const { hash, bytes } = signer.sign(
  txMsg
  secret,
);

IBCTransfer

Create an IBC transfer transaction:

Rust

// Assume we have Borsh-encoded messages "ibc_transfer_msg" and "tx_msg", and "secret" (String):
let IbcTranfer { tx_data } = IbcTransfer::new(ibc_transfer_msg)
    .expect("IbcTransfer should instantiate");
let signer = Signer::new(&tx_data);
let transaction = signer.sign(tx_msg, secret)
    .expect("Should be able to sign transaction");

TypeScript

// Assume we have Borsh-encoded messages "ibcTranferMsg" and "txMsg", and "secret" (String):
const ibcTransfer = new IbcTransfer(
  port,
  channel,
  token,
  sender,
  receiver,
  amount
);
const { hash, bytes } = ibcTransfer.to_tx(
  secret,
  epoch,
  feeAmount,
  gasLimit,
  txCode
);

Account

Create an "init-account" transaction for receiving an established address from an implicit address:

Rust

// Assume we have Borsh-encoded messages "account_msg" and "tx_msg", and "secret" (String):
let Account { tx_data } = Account::new(account_msg, secret);
let signer = Signer::new(&tx_data);
let transaction = signer.sign(tx_msg, secret)
    .expect("Should be able to convert to transaction");

TypeScript

const account = new Account(secret, vpCode);
const { hash, bytes } = account.to_tx(
  secret,
  token,
  epoch,
  feeAmount,
  gasLimit,
  txCode
);
