The Hardy brothers eventually caught the eyes of the World Wrestling Federation (WWF).
After being signed to a contract in 1998, they were trained by Dory Funk Jr. in his Funkin' Dojo with other notable wrestlers such as Kurt Angle, Christian, Test, and A-Train.
When the team was finally brought up to WWF television, after months of "jobbing" and live events, they formed the acrobatic tag team called the Hardy Boyz.
While feuding with The Brood in mid-1999, they added Michael Hayes as their manager.
On July 5, they won their first WWF Tag Team Championship by defeating the Acolytes, but lost it back to them a month later.
After the dissolution of the Brood, the Hardys joined forces with Gangrel as The New Brood and feuded with Edge and Christian.
This stable did not last long, however, and on October 17, 1999 at No Mercy, the Hardy Boyz won the managerial services of Terri Runnels in the finals of the Terri Invitational Tournament in the WWF's first ever tag team ladder match against Edge and Christian.
They competed in the first ever tag team triple threat ladder match against The Dudley Boyz, and Edge & Christian at WrestleMania 2000, in which Edge & Christian won.
During the match, Hardy performed a Swanton Bomb to Bubba Ray Dudley off a 20-foot ladder.

In 2000, the Hardy Boyz found a new manager in their real-life friend Lita.
Together, the three became known as "Team Xtreme".
They continued their feud with Edge and Christian throughout 2000, defeating them for the WWF Tag Team Championship on two occasions.
At SummerSlam, the Hardy Boyz competed in perhaps the most physically demanding type of match they had competed in thus far- the first ever Tables, Ladders, and Chairs match (TLC match)- in their hometown of Raleigh, for the Tag Team Championship against the Dudley Boyz and Edge & Christian, but were unsuccessful.
The second TLC match at Wrestlemania 17 in Houston, which is regarded as one of the greatest matches in WWE history they faced off once again against Edge & Christian and the Dudley Boyz but lost to the former.

Hardy gained attention for his high risk stunts in the TLC matches, such as doing Swanton Bomb frontflips off of the top steps of 10 and 20 foot high ladders, making a name for himself as one of the most seemingly reckless and unorthodox WWF performers of his time.
In 2001, Hardy received a push as a singles competitor, and he held the Intercontinental (defeating Triple H), Light Heavyweight (defeating Jerry Lynn) and Hardcore Championships (defeating Mike Awesome and Van Dam on two separate occasions).
At the end of 2001, the Hardys began a storyline in which they began to fight, which led to Matt demanding a match at Vengeance, with Lita as the special guest referee.
After Hardy beat Matt by pinfall at Vengeance, while Matt's foot was on the ropes, Hardy and Lita began feuding against Matt.
In the middle of the feud, however, Hardy faced The Undertaker in a Hardcore Championship match and lost.
After the match, The Undertaker was scripted to attack both Hardy and Lita, injuring them.
On the next episode of SmackDown!,
The Undertaker attacked Matt as well, also injuring him, in storyline.
The Hardys and Lita were not seen again until the Royal Rumble, because WWF did not have another storyline for their characters.
The Hardys later came back as a team, and there was never any mention of their previous storyline split.

In early April 2002, the Hardy Boyz began a feud with Brock Lesnar after Lesnar gave Matt an F-5 on the steel entrance ramp, which led to an angered Hardy seeking revenge on Lesnar.
At Backlash, Hardy faced-off against Lesnar in Lesnar's first televised match.
Lesnar dominated Hardy and won the match by knockout.
Lesnar and the Hardys continued to feud over the next few weeks, with the Hardys coming out victorious only once by disqualification.
At Judgment Day, Lesnar gained the upper hand on the Hardy Boyz before tagging his partner, Paul Heyman, in to claim the win for the team.
In July 2002, Hardy won his third Hardcore Championship by defeating Bradshaw.
