View Source Signet.Erc20 (Signet v1.3.8)

A wrapper for an ERC-20 contract, allowing the code to interact by pulling data from the contract, or sending transaction to it.

Summary

Types

call_opts()
exec_opts()

Functions

call_trx(token, call_data, call_opts)
errors()

Returns a list of known error codes (ABI signatures), which can be used when parsing error messages from contract calls.

exec_trx(token, call_data, exec_opts)
transfer(token, destination, amount_wei, exec_opts \\ [])

Executes a transfer transaction.

transfer(token, destination, amount_wei, exec_opts \\ [])

View Source 
@spec transfer(Signet.contract(), Signet.address(), non_neg_integer(), [exec_opts()]) ::
  {:ok, binary()} | {:error, term()}

Executes a transfer transaction.

Arguments:

  • destination: The destination address
  • amount_wei: The amount, in token wei, to transfer.
  • exec_opts: Execution options, such as the gas price for the transaction.
