The trial was provoked following the Aquaman actress' 2018 Washington Post op-ed, which spoke about the need for more support for women who faced domestic abuse. She didn't name Depp in the story.
The Pirates of the Caribbean actor has staunchly denied abusing Heard and filed a defamation suit against her in response to the publication of her story.
The trial took place in Virginia, and due to the state laws that permitted it to be livestreamed online, it was carefully followed by people across the globe.
And while some fans rallied together via social media to express their support for Depp, some of them became hostile as they bombarded his daughter, Lily-Rose, with abusive messages on Instagram, as reported by BuzzFeed News.
Aside from a post highlighting her 23rd birthday on May 28, Lily-Rose was not active on her social media account amid the trial.
"Silence, exile, cunning" is paraphrased from the novel A Portrait of the Artist as a Young Man by James Joyce. Depp also has the three words tattooed on his forearm.
A spokesperson for Johnny Depp told Indy100 that the images were not a message to Lily-Rose, who he "loves and adores."
They said that underlying art is Johnny’s art, and he drew the portraits and penned the words themselves as "separate pieces."
"When working with the NFT team, that art was then randomized and edited to create thousands of individual and unique pieces that stem from the same underlying pieces," the spokesperson said.
They added: "The pictures of Lily-Rose with those specific words are an unfortunate coincidence of the randomization, and we are working through our options to try to get them removed as quickly as possible."
Purchasing one of Depp's NFTs gives supporters access to a private Discord group, where they can collaborate on creative projects. Donations are also made to Depp's chosen charities.
"I'm hoping we can form a new friendship group around these NFTs. My involvement in the NFT space is only getting started," Johnny added.
Despite Lily-Rose not speaking out in the most recent case, she defended her father when Amber's allegations against him first came to the surface in 2016.
In a since-deleted Instagram post, she shared a picture of the actor helping her to walk when she was a baby and wrote that her father was "the sweetest, most loving person" she knew and that she, her brother and many others would agree.
Depp shares Lily-Rose and 20-year-old son Jack with his ex Vanessa Paradis. Jack is not featured in any of Depp's NFTs.
