The co-founder and chief executive officer of Twitter, Jack Dorsey, was paid a salary of just US$1.40 (€1.24) in 2018.

That is according to a regulatory filing from the US Securities and Exchange Commission (SEC).

The proxy statement read: "As a testament to his commitment to and belief in Twitter's long-term value creation potential, our CEO, Jack Dorsey, declined all compensation and benefits for 2015, 2016 and 2017, and in 2018 he declined all compensation and benefits other than a salary of $1.40."

The document also said this was "at his own recommendation".

It comes ahead of an annual meeting of stockholders on May 20th.

However the very low salary, which some see as a nod to Twitter's original character limit of 140, will not see Mr Dorsey go without.

According to Forbes, he is worth US$5.3bn (€4.7bn).

Twitter previously announced plans to double the character limit allowed in an individual tweet from 140 characters up to 280.

While Mr Dosey himself has also hinted at an edit button for users in the near-future.

Speaking in February, he said: "The reason we don't have it in the first place is we were born on SMS, we were born on text messaging - when you send a text you can't take it back".

"So when you send a tweet it goes to the world instantaneously - you can't take it back".

"But you could build it such that maybe we introduce a five send to 30 second delay in the sending, and within that window you can edit".

He added: "The issue with going longer than that, it takes that real-time nature and the conversational flow out of it."
