UniversalSettle (`exact` rail)

Layout

Rust workspace universalsettle/: api/ (IDL-like API + builders), program/ (cdylib on-chain), cli/ (universalsettle binary).

Commands (from workspace root)

cd universalsettle
cargo test
cargo build --release -p universalsettle-cli

Program-level SBF / test-sbf flows depend on installed Solana/Steel toolchain—follow universalsettle/README.md and universalsettle/scripts/README.md.

Semantics reminders

HTTP POST /settle on pr402 ≠ an on-chain “Settle” instruction; vault flow centers on CreateVault, Sweep, plus admin ops listed in README.

Formatting and Clippy: use x402-rust-solana-workflow.

pr402-buyer

miraland-labs/x402

Integrate an x402 buyer agent on Solana via pr402 (ipay.sh): HTTP 402 challenges, build-exact-payment-tx, PAYMENT-SIGNATURE, MCP tools, createPay402Fetch, and Forge marketplace purchases. Use whenever the user builds a paying agent, auto-pays API calls, handles Payment-Required headers, mentions x402 buyer, pr402 buyer, X402Client, @pr402/client, @pr402/mcp-server, x402-buyer-starter, x402-subscription-client, subscription JWT Bearer, forge-cli, agentic payments, or machine economy. If seller vs buyer is unclear, load **pr402** first.

pr402-seller

miraland-labs/x402

Integrate an x402 seller on Solana via pr402 (ipay.sh): HTTP 402 gates, SplitVault onboarding, PAYMENT-SIGNATURE verify/settle, and discovery enrollment. Use whenever the user monetizes an API, adds pay-per-call, implements HTTP 402, mentions x402 seller, pr402 seller, X402SellerSDK, merchant wallet, SplitVault, x402-resources.json, x402-seller-starter, x402-subscription-starter, subscription, hourly daily monthly JWT subscribe, or exact-rail UniversalSettle. If seller vs buyer is unclear, load **pr402** first.

x402-ecosystem-hub

miraland-labs/x402

Maps the x402 repository as a documentation and coordination hub (not a Cargo/workspace root) linking pr402, on-chain rails, the oracles workspace, starters, and paid-service examples. Use when navigating this repo, explaining ecosystem layout, locating project folders, or choosing which codebase to edit.

x402-rust-solana-workflow

miraland-labs/x402

Runs formatting, Clippy, tests, and builds for Rust crates and Solana program workspaces under the x402 hub. Use when editing any `Cargo.toml` project here, before proposing a PR, or when the user asks for fmt/clippy/test/build commands.
