Constants

const TmLsig = `` /* 9365-byte string literal not displayed */

TmLsig is a tinyman lsig contract used in tests/benchmarks

Functions

func CreateTinyManSignedTxGroup

func CreateTinyManSignedTxGroup(tb testing.TB, txns []Txn) ([]transactions.SignedTxn, []*crypto.SignatureSecrets)

CreateTinyManSignedTxGroup repro this tx group by tinyman https://algoexplorer.io/tx/group/d1bUcqFbNZDMIdcreM9Vw2jzOIZIa2UzDgTTlr2Sl4o%3D which is an algo to USDC swap. The source code below is extracted from algoexplorer, which adds some unusual stuff as comments

func Group

func Group(txns ...*Txn) []transactions.SignedTxn

Group turns a list of Txns into a slice of SignedTxns with GroupIDs set properly to make them a transaction group. The input Txns are modified with the calculated GroupID.

Txn exists to simplify writing tests where transaction.Transaction might be unwieldy. Txn simplifies testing in these ways: * Provides a flat structure to simplify object construction. * Defines convenience methods to help setup test state.

func CreateTinyManTxGroup

func CreateTinyManTxGroup(tb testing.TB, randNote bool) []Txn

CreateTinyManTxGroup repro this tx group by tinyman https://algoexplorer.io/tx/group/d1bUcqFbNZDMIdcreM9Vw2jzOIZIa2UzDgTTlr2Sl4o%3D

func (Txn) Args

func (tx Txn) Args(strings ...string) *Txn

Args returns a new Txn with the given strings as app args

func (*Txn) FillDefaults

func (tx *Txn) FillDefaults(params config.ConsensusParams)

FillDefaults populates some obvious defaults from config params, unless they have already been set.

func (Txn) Noted

func (tx Txn) Noted(note string) *Txn

Noted returns a new Txn with the given note field.

func (Txn) SignedTxn

func (tx Txn) SignedTxn() transactions.SignedTxn

SignedTxn produces a unsigned, transactions.SignedTransaction from the fields in this Txn. This seemingly pointless operation exists, again, for convenience when driving tests.

func (Txn) SignedTxnWithAD

func (tx Txn) SignedTxnWithAD() transactions.SignedTxnWithAD

SignedTxnWithAD produces unsigned, transactions.SignedTxnWithAD from the fields in this Txn. This seemingly pointless operation exists, again, for convenience when driving tests.

func (Txn) Txn

func (tx Txn) Txn() transactions.Transaction

Txn produces a transactions.Transaction from the fields in this Txn
