From 49843d8a2061220706260cf0eabd042cfeaa1f5f Mon Sep 17 00:00:00 2001 From: 0xfnzero <0xfnzero@users.noreply.github.com> Date: Fri, 8 May 2026 23:23:39 +0800 Subject: [PATCH] fix(pump): default token program to legacy SPL Token instead of Token-2022 The `effective_pump_mint_token_program` helper was defaulting to TOKEN_PROGRAM_2022 when `token_program` was Pubkey::default(), causing Anchor error 0xbbf (account owned by wrong program) for all legacy PumpFun coins whose ATAs are owned by the original Token Program. Fall back to TOKEN_PROGRAM (legacy) when no explicit token program is provided. Token-2022 must be set explicitly for create_v2 coins.
