All 3 SNP enactment candidates person predicted that Scotland tin beryllium an autarkic state wrong 5 years if they triumph the contest.
Ash Regan, Humza Yousaf and Kate Forbes were speaking arsenic they faced each different successful a BBC Scotland TV debate.
Mr Yousaf said helium believed the state "can and volition be" autarkic by 2028 successful effect to a question from an assemblage member.
Ms Regan and Ms Forbes some said they believed the same.
The enactment contention was sparked by Nicola Sturgeon's astonishment announcement that she was quitting arsenic some SNP person and Scotland's archetypal curate aft 8 years successful the roles.
Recent polls person enactment enactment for independency astatine broadly the aforesaid level arsenic it was erstwhile Ms Sturgeon succeeded Alex Salmond aft the referendum successful 2014, which saw Scottish voters cull independency by 55% to 45%.
That is contempt the turbulence successful UK authorities successful caller years that saw the state permission the EU contempt Scotland voting overwhelmingly successful favour of remaining and Boris Johnson's often chaotic clip arsenic premier minister.
The Supreme Court has besides ruled that the Scottish Parliament does not person the powerfulness to clasp a referendum without the statement of the UK authorities - which has repeatedly made wide that it has nary volition of granting ceremonial consent done a Section 30 order.
Mr Yousaf, the wellness caput who is the bookies favourite to triumph the contention and is wide viewed arsenic being Ms Sturgeon's preferred candidate, told the Debate Night Special that helium believed helium could physique sustained bulk enactment for independency that would spot those governmental obstacles disappear.
He added: "I would privation to beryllium the 1 who delivers independence, but to bash that you've got to halt talking astir process and speech astir policy.
"We person got to animate radical with a imaginativeness for independence. We person to marque definite that we're not obsessing astir Section 30s and de facto referendums due to the fact that radical conscionable don't get inspired by that."
Who are the SNP candidates?
Ms Forbes, the concern caput who is presently seen arsenic being Mr Yousaf's closest challenger for the leadership, said she believed the dial could beryllium shifted successful favour of independency by gathering a lawsuit connected the issues that radical were acrophobic about.
Using the illustration of the outgo of surviving crisis, she said: "People can't spend adjacent month's vigor measure successful a state that is affluent successful vigor successful presumption of lipid and state and successful presumption of our renewables. It doesn't stack up due to the fact that the decisions are being made far, acold distant from those that are astir affected.
"I deliberation we should beryllium utilizing each antiauthoritarian opportunities to run for and marque the lawsuit for independency but successful a mode that is respectful of the reasons wherefore radical whitethorn not beryllium persuaded".
Meanwhile, Ms Regan outlined her plans for what she calls a Voter Empowerment Mechanism that "just uses the ballot container to let the radical of Scotland to accidental erstwhile they are acceptable to beryllium independent".
She added: "You tin usage each and each election. So you could commencement with the adjacent predetermination and past the Scottish predetermination aft that. And it's determination successful the inheritance and past the radical of Scotland determine erstwhile they're acceptable to go independent."
Ms Regan discontinue arsenic the country's assemblage information curate implicit the government's arguable sex designation plans, and is seen arsenic being the outsider successful the contest.
The candidates besides faced questions connected topics including NHS waiting lists - with 1 assemblage subordinate saying her hubby has chronic wellness problems and is facing a six-year waiting database - arsenic good arsenic the authorities of Scotland's acquisition strategy and the government's arguable Deposit Return Scheme.
This has, broadly, been a statement focused connected argumentation alternatively than property - thing summed up erstwhile Humza Yousaf said helium was "not going to beryllium present and slag disconnected colleagues successful government".
He did clash with Kate Forbes implicit her attack to business, but that was teed up by the assemblage much than the candidates themselves.
When fixed the chance, the trio person not sought to onshore punches connected each other. The cross-examination information of the statement was notably little fiery than successful erstwhile events.
That whitethorn beryllium successful portion due to the fact that yellow-on-yellow attacks are greeted with glee by absorption parties, but it is besides a people of however the candidates person developed their approach.
Rather than seeking to savage Humza Yousaf successful the cross-examination section, this clip Kate Forbes asked policy-laden questions which promoted her ain strengths connected economical issues.
Ash Regan brought up sex betterment - again, thing she sees arsenic a spot of her ain campaign.
Humza Yousaf was really ticked disconnected by Stephen Jardine for talking astir his ain policies astatine magnitude erstwhile helium was meant to beryllium questioning Kate Forbes.
This whitethorn beryllium due to the fact that of the fearfulness that mud thrown present could inactive beryllium stuck erstwhile aboriginal elections rotation around.
But it whitethorn besides beryllium due to the fact that this contention uses a azygous transferable ballot strategy - and successful a choky contest, second-preference votes could crook retired to beryllium crucial.
It whitethorn beryllium much profitable to marque friends than to effort to sound retired opponents entirely.
Voting successful the SNP enactment election, which is utilizing the azygous transferable ballot system, opened connected Monday with the victor to beryllium announced connected 27 March.
The SNP has refused to corroborate precisely however galore enactment members volition beryllium capable to instrumentality portion successful the vote, with its Westminster person Stephen Flynn telling BBC Scotland earlier connected Tuesday that helium had "no idea" and that "I deliberation the past clip I heard it was astir 100,000."
The SNP said its rank had reached 125,000 by 2019, but the Electoral Commission put the fig astatine 104,000 2 years later.
The Mail connected Sunday has reported that Southampton-based polling steadfast Mi-Voice, which is overseeing the enactment vote, has been fixed the names of conscionable 78,000 members by the SNP.
If this is correct, it would suggest that the enactment whitethorn person mislaid astir 50,000 members implicit the past 4 years. The paper besides reported that Mi-Voice expected astir 54,000 members to really taxable a vote.
Polling adept Prof Sir John Curtice has said Mr Yousaf currently appears to beryllium the astir popular of the 3 candidates among the SNP members who volition beryllium picking the caller leader, with Ms Forbes 2nd and Ms Regan third.
But Ms Forbes seems to beryllium much fashionable than her rivals with some SNP voters and the nationalist arsenic a whole, Sir John said.
He added that it "looks arsenic though determination is plentifulness to play for" and that "maybe everything could crook connected the chartless 2nd preferences of Ms Regan's supporters".
Whoever wins the SNP enactment contention volition look a Scottish Parliament ballot connected 28 March to corroborate them arsenic the caller archetypal minister, earlier being sworn into bureau the pursuing day.
