From e210fda77049bfede41ec31c961867166d9af3c0 Mon Sep 17 00:00:00 2001 From: A1igator Date: Fri, 8 May 2026 20:25:53 -0700 Subject: [PATCH] initial pilot implementation: 6 Anchor programs Faithful SVM port of base/commerce-payments authCapture primitives plus x402r-specific extensions: programs/auth-capture-escrow AuthCaptureEscrow analog: 6 lifecycle instructions + protocol-fee config init. CPIs into ITokenCollector for fund moves. programs/spl-token-collector ITokenCollector for SPL Token. Two instructions: collect_authorize + collect_refund. Future Token-2022, bridge, streaming collectors slot in via the same interface. programs/payment-operator x402r factory + slot dispatch. One program acting as factory of per-merchant OperatorState PDAs (whose addresses double as paymentInfo.operator). Wraps escrow ixs with pre-action conditions + post-action hooks via invoke_signed CPI. programs/static-address-condition Generic ICondition reference impl. programs/receiver-condition Stateless ICondition (= payment_info.receiver). programs/payer-condition Stateless ICondition (= payment_info.payer). Plus tests/, fuzz/, migrations/, codama/ scaffolding. Architectural symmetry table is in README.md. Spec lives at x402r-scheme/specs/schemes/authCapture/scheme_authCapture_svm.md. Pilot, unaudited. Mainnet usage at users' own risk. Every Rust source file carries SPDX-License-Identifier: BUSL-1.1, matching x402r-contracts. Each Cargo.toml declares license = "BUSL-1.1".
