Builds and signs a transaction, to be ready to be passed to JSON-RPC.

Optionally takes a callback to modify the transaction before it is signed.

Examples

iex> signer_proc = Signet.Test.Signer.start_signer()
iex> {:ok, signed_trx} = Signet.Transaction.build_signed_trx(<<1::160>>, 5, {"baz(uint,address)", [50, :binary.decode_unsigned(<<1::160>>)]}, {50, :gwei}, 100_000, 0, signer: signer_proc, chain_id: :goerli)
iex> {:ok, signer} = Signet.Transaction.V1.recover_signer(signed_trx, 5)
iex> Signet.Hex.to_address(signer)

Builds and signs a V2 transaction, to be ready to be passed to JSON-RPC.

Optionally takes a callback to modify the transaction before it is signed.

Examples

iex> {:ok, signer} = Signet.Transaction.V2.recover_signer(signed_trx)
iex> Signet.Hex.to_address(signer)
"0x63Cc7c25e0cdb121aBb0fE477a6b9901889F99A7"
