Johnny Depp has donated nearly $800,000 to four children's hospitals, including the one Amber Heard had pledged millions of dollars to after selling his NFTs.

The 59-year-old Pirates of the Caribbean star launched his first NFT non-fungible tokens — unique digital assets traded through blockchain technology — titled Never Fear Truth before he and Heard began their defamation trial.

Following his legendary court victory against Heard, Depp sold the Never Fear Truth tokens and donated the proceeds to the Children's Hospital of Los Angeles, Perth Children's Hospital Foundation, the Footprint Coalition, and the Great Ormond Street Hospital Children's Charity.

Though there has been much controversy, Depp's donation is seen as a slight dig at ex-wife Heard, who was supposed to donate millions from her divorce settlement to the Children's Hospital of Los Angeles but failed to do so.

After donating, Depp's company, Never Fear Truth, released a statement, writing:

"We are pleased to be able to confirm that nearly $800,000 (£667,000) in total donations."

Never Fear Truth describes Depp's art as "an important outlet for his creativity" and explains it exists "at the intersection of 'Pop Art' and 'Street Art."

The description of the tokens reads:

"Recognizable images of people in popular culture are recast in vibrant, bright colors; and overlayed with the energy and wit of Street Art."

"The result is a series of iconic images of media figures that have moved beyond the impersonal graphic simplicity of Pop Art. It's Pop Art with feeling."

Depp's fans hailed the actor after his generous donations to charities. Several also dissed Heard for not fulfilling her promise to donate the money.

In 2017, Heard promised to donate $7 million to two charities; The Children's Hospital of Los Angeles and the American Civil Liberties Union (ACLU).

She stated that the money would be split equally between the two charities she had worked with for the past ten years.

She explained:

"Money played no role for me personally and never has, except to the extent that I could donate it to charity and, in doing so, hopefully, help those less able to defend themselves,"

However, during the duo's high-profile defamation trial, it was revealed that the Aquaman actress didn't fulfill her pledge.

A Children's Hospital of Los Angeles representative said they had only received $250,000 directly from Heard since 2017. However, the spokesperson also admitted Heard hadn't worked out a donations schedule.

On the other hand, the chief operating officer and general counsel at ACLU said his charity had received $350,000 directly from Heard and $100,000 from Depp.

Heard ultimately blamed her court battle with ex-husband Depp for the oversight.
