Wales' players could earn up to £100,000 each if they win the 2011 World Cup in New Zealand, BBC Sport Wales understands.
The Welsh Rugby Union and players' association have struck a payment deal that covers all Test matches until the end of the 2016 season.
Any player who appears in every round of a successful 2011 World Cup campaign would take home £100,000.
The WRU also wants to resurrect its A team to help develop Test players.
A WRU statement read: "This new player contract includes the next two Rugby World Cups in 2011 and 2015, tours to Australia (2012), Japan (2013), South Africa (2014), New Zealand (2016), RBS 6 Nations Tournaments (2012-2016) and all the Autumn internationals and June home fixtures over the next five years.
"The payments to players are based on rewarding success over and above a basic fee.
"The contract identifies and establishes basic match fees, bonuses and commercial player appearances on behalf of the WRU in a unique all-embracing deal.
"This new agreement also assures match funding for players selected for any Wales A games to underline the aim of the WRU to bring back the second tier senior internationals in future and build upon our player pathways."
The deal was concluded by WRU group chief executive Roger Lewis, captain Matthew Rees and Welsh Rugby Players Association chair Gethin Jenkins - the Wales and British and Irish Lions prop.
