The Warriors and Curry's camp have finalized a four-year deal worth $11 million annually, according to the Contra Costa Times, that will take effect starting next season.
Golden State was keen to secure Curry long-term as one of its two cornerstones, alongside center Andrew Bogut, despite Curry's ongoing struggles with ankle problems.
Curry tweeted recognition of the deal and thanks to Warriors ownership Wednesday: "#Dubs Gameday baby. And thanks to Joe Lacob & the Warriors hopefully I can say that for the next 4 yrs. agreed on extension."
Curry missed 40 of 66 games last season and sprained his twice-surgically repaired right ankle again in the preseason. New Warriors general manager Bob Myers and Lacob felt Curry was still worth the risk given the point guard's production when healthy.
The 24-year-old Curry averaged career lows of 14.7 points, 5.3 assists and 3.4 rebounds last season. He has still proven to be one of the NBA's most prolific shooters when he's on the court. Curry has shot 47 percent from the field and 44 percent from 3-point range in his first three seasons.
The Warriors are counting on Curry to form half of the new franchise tandem.
Curry is expected to team with Bogut, who didn't play in the preseason. The team has said Bogut has not had any setbacks on his surgically repaired left ankle, which he fractured on Jan. 25 while with Milwaukee and missed the rest of the season.
Curry sat out the last two exhibitions after he sprained his right ankle at Portland but is expected to play in the season opener. The former Davidson star, drafted seventh overall by the Warriors in 2009, had arthroscopic surgery in April and had surgery to repair a tendon in the ankle in the summer of 2011.
The Bogut-Curry combo has enough support around it for the Warriors to believe they have a strong shot to make the playoffs for only the second time since 1994 -- if all can stay healthy, which hasn't been the case in recent seasons.
First-round picks from 2009 faced a Wednesday midnight deadline to secure a contract extension. Those who don't, in most cases, will become restricted free agents in July.
