The **default is `"Mesh"`**, which uses `alternative` — NOT `constructor`: + +| Format | Keyword | Field Values | Example | +|--------|---------|-------------|---------| +| `"Mesh"` (default) | `alternative` | Primitives directly | `{ alternative: 0, fields: [42, "hex"] }` | +| `"JSON"` (cardano-cli) | `constructor` | Typed wrappers | `{ constructor: 0, fields: [{ int: 42 }, { bytes: "hex" }] }` | +| `"CBOR"` | N/A | Hex string | `"d8799f182aff"` | + +**Wrong:** +```typescript +// WRONG - "constructor" with default Mesh type +.txOutInlineDatumValue({ constructor: 0, fields: [{ int: 42 }] }) +``` + +**Correct:** +```typescript +import { mConStr0 } from '@meshsdk/common'; + +// Option 1: Mesh format with "alternative" +.txOutInlineDatumValue({ alternative: 0, fields: [42] }) + +// Option 2: Use Mesh helper +.txOutInlineDatumValue(mConStr0([42])) + +// Option 3: If you MUST use "constructor", specify "JSON" type explicitly +.txOutInlineDatumValue({ constructor: 0, fields: [{ int: 42 }] }, "JSON") +``` + +--- + +### Missing "JSON" Type Parameter for JSON-Format Datums + +**Issue:** Datum appears correct but script validation fails or datum doesn't match expected hash. + +**Cause:** Using JSON-format datum helpers (`conStr0()`, `integer()`, etc.) without specifying `"JSON"` as the type parameter.

The **default is `"Mesh"`**, which uses `alternative` — NOT `constructor`: + +| Format | Keyword | Field Values | Example | +|--------|---------|-------------|---------| +| `"Mesh"` (default) | `alternative` | Primitives directly | `{ alternative: 0, fields: [42, "hex"] }` | +| `"JSON"` (cardano-cli) | `constructor` | Typed wrappers | `{ constructor: 0, fields: [{ int: 42 }, { bytes: "hex" }] }` | +| `"CBOR"` | N/A | Hex string | `"d8799f182aff"` | + +**Wrong:** +```typescript +// WRONG - "constructor" with default Mesh type +.txOutInlineDatumValue({ constructor: 0, fields: [{ int: 42 }] }) +``` + +**Correct:** +```typescript +import { mConStr0 } from '@meshsdk/common'; + +// Option 1: Mesh format with "alternative" +.txOutInlineDatumValue({ alternative: 0, fields: [42] }) + +// Option 2: Use Mesh helper +.txOutInlineDatumValue(mConStr0([42])) + +// Option 3: If you MUST use "constructor", specify "JSON" type explicitly +.txOutInlineDatumValue({ constructor: 0, fields: [{ int: 42 }] }, "JSON") +``` + +--- + +### Missing "JSON" Type Parameter for JSON-Format Datums + +**Issue:** Datum appears correct but script validation fails or datum doesn't match expected hash. + +**Cause:** Using JSON-format datum helpers (`conStr0()`, `integer()`, etc.) without specifying `"JSON"` as the type parameter.

The facilitator rejects with +`REQUIREMENTS_MISMATCH` if `paymentPayload.accepted` doesn't exactly match it — this is what stops a client +from building a payload against terms it invented itself (a trivial amount, its own address, or, for `masumi`, +substituted admin keys) instead of what was actually offered. + +## Masumi escrow lifecycle (spend side) + +Beyond locking a payment into the `masumi` escrow, `src/masumi/spend/` implements every way +funds can legitimately leave it, matching `vested_pay.ak`'s full action set: + +```ts +import { + buildSubmitResultTx, buildWithdrawTx, buildAuthorizeRefundTx, // seller actions + buildSetRefundRequestedTx, buildAuthorizeWithdrawalTx, buildWithdrawRefundTx, // buyer actions + buildWithdrawDisputedTx, signAdminIntent, verifyAdminSignature, // admin-quorum settlement +} from "@meshsdk/x402"; + +// e.g. seller delivers, then withdraws once the buyer has authorized it (or unlock_time has passed): +const tx = await buildSubmitResultTx(escrowUtxo, currentDatum, resultHashHex, sellerWallet, deployment, { + fetcher, evaluator, currentSlot, // `evaluator` is required here (unlike client/build.ts's ChainContext) - +}); // spending a script needs real ExUnits estimation, not just fee calc. +``` + +Each builder takes the escrow's current `UTxO` + its parsed datum (`parseMasumiLockDatum`), the relevant +wallet, the `MasumiDeployment` the escrow was locked under, and a `SpendContext`. `buildWithdrawDisputedTx` +is the odd one out: it has no buyer/seller signer at all, gated instead by an M-of-N CIP-8 admin-signature +quorum (`adminVkeys`/`requiredAdmins` on the deployment) — collect each admin's signature separately via +`signAdminIntent`, verify with `verifyAdminSignature`, then pass the collected set in. + +Live-validated end to end against the real deployed `vested_pay` contract on preprod (not just unit-tested): +lock → SubmitResult → SetRefundRequested → AuthorizeWithdrawal → Withdraw; lock → AuthorizeRefund → +WithdrawRefund; and `WithdrawDisputed` against a custom 1-of-1 test deployment. See +`test/integration/masumi-*-live.integration.test.ts`. + +## Attribution + +The Masumi `vested_pay` escrow support (`src/masumi/`) ports several files near-verbatim from +[`x402-foundation/x402`](https://github.com/x402-foundation/x402) (Apache-2.0), adapted to Mesh's +primitives in place of Evolution SDK, so the two implementations agree byte-for-byte on the +compiled validator, digests, and deadline/collateral math: `blueprintCode.ts`, `constants.ts`, +`jcs.ts`, parts of `terms.ts` (from `digests.ts`), `datum.ts`, `lock.ts`, and `escrow-address.ts` +(from `blueprint.ts`). See each file's header comment for its specific source path. + +## Testing + +`npm test` runs the full unit test suite (client/facilitator/masumi end-to-end flows for all three +`assetTransferMethod`s, facilitator rule isolation, settlement idempotency, COSE signature binding, byte-exact +CIP-8 vectors) against an in-memory fetcher/wallet — no live network, no credentials required. This is the +project's primary correctness gate and is expected to stay green with no live-chain dependency. + +`npm run test:integration` runs live Cardano preprod tests — real transactions against the real deployed +`vested_pay` contract, not mocks — covering the payment lock for all three methods plus the full masumi spend +lifecycle described above. It needs a `.env` with a preprod Blockfrost project ID and a funded preprod wallet +mnemonic, neither of which this repo provides or should ever have committed to it (`.env` is gitignored). Not +part of the default `npm test`/CI loop, since it costs real (test) ADA and takes tens of minutes end to end — +run it deliberately, not on every change. + +[meshjs.dev](https://meshjs.dev/) diff --git a/packages/mesh-x402/jest.config.ts b/packages/mesh-x402/jest.config.ts new file mode 100644 index 000000000..e049d81f5 --- /dev/null +++ b/packages/mesh-x402/jest.config.ts @@ -0,0 +1,21 @@ +import type { Config } from "jest"; + +const jestConfig: Config = { + clearMocks: true, + maxWorkers: 1, + testEnvironment: "node", + testMatch: ["**/packages/**/*.test.ts"], + testPathIgnorePatterns: ["/node_modules/", "\\.integration\\.test\\.ts$"], + setupFiles: ["dotenv/config"], + preset: "ts-jest", + moduleNameMapper: { + "^(\\.{1,2}/.*)\\.js$": "$1", + }, + transform: { + "^.+\\.[jt]s?$": "ts-jest", + }, + transformIgnorePatterns: ["/node_modules/(?!@meshsdk/.*)"], + passWithNoTests: true, +}; + +export default jestConfig; diff --git a/packages/mesh-x402/jest.integration.config.ts b/packages/mesh-x402/jest.integration.config.ts new file mode 100644 index 000000000..3e2faeae4 --- /dev/null +++ b/packages/mesh-x402/jest.integration.config.ts @@ -0,0 +1,11 @@ +import type { Config } from "jest"; + +import base from "./jest.config"; + +const jestConfig: Config = { + ...base, + testMatch: ["**/packages/**/*.integration.test.ts"], + testPathIgnorePatterns: ["/node_modules/"], +}; + +export default jestConfig; diff --git a/packages/mesh-x402/package.json b/packages/mesh-x402/package.json new file mode 100644 index 000000000..52a08bfe8 --- /dev/null +++ b/packages/mesh-x402/package.json @@ -0,0 +1,63 @@ +{ + "name": "@meshsdk/x402", + "version": "1.9.1", + "description": "x402 payments (Cardano exact scheme) - https://meshjs.dev/apis/x402", + "main": "./dist/index.cjs", + "browser": "./dist/index.js", + "module": "./dist/index.js", + "types": "./dist/index.d.ts", + "type": "module", + "exports": { + ".": { + "types": "./dist/index.d.ts", + "import": "./dist/index.js", + "require": "./dist/index.cjs" + } + }, + "files": [ + "dist/**" + ], + "scripts": { + "build:mesh": "tsup src/index.ts --format esm,cjs --dts", + "clean": "rm -rf .turbo && rm -rf dist && rm -rf node_modules", + "dev": "tsup src/index.ts --format esm,cjs --watch --dts", + "format": "prettier --check . --ignore-path ../../.gitignore", + "lint": "eslint", + "pack": "npm pack --pack-destination=./dist", + "test": "jest", + "test:integration": "jest --config jest.integration.config.ts" + }, + "devDependencies": { + "@meshsdk/configs": "*", + "@meshsdk/provider": "^1.9.0-beta.105", + "@types/node": "^20.11.0", + "dotenv": "^16.4.5", + "eslint": "^8.57.0", + "tsup": "^8.0.2", + "typescript": "^5.3.3" + }, + "dependencies": { + "@harmoniclabs/cbor": "1.6.0", + "@harmoniclabs/plutus-data": "1.2.6", + "@meshsdk/common": "1.9.1", + "@meshsdk/core-cst": "1.9.1", + "@meshsdk/transaction": "1.9.1", + "@meshsdk/wallet": "1.9.1", + "@noble/hashes": "^1.5.0", + "hono": "^4.6.0" + }, + "prettier": "@meshsdk/configs/prettier", + "publishConfig": { + "access": "public" + }, + "license": "Apache-2.0", + "keywords": [ + "cardano", + "ada", + "web3", + "blockchain", + "sdk", + "x402", + "payments" + ] +} diff --git a/packages/mesh-x402/src/client/build.ts b/packages/mesh-x402/src/client/build.ts new file mode 100644 index 000000000..e93a41ede --- /dev/null +++ b/packages/mesh-x402/src/client/build.ts @@ -0,0 +1,114 @@ +import { MeshTxBuilder } from "@meshsdk/transaction"; +import { MeshWallet } from "@meshsdk/wallet"; +import { IFetcher, Protocol } from "@meshsdk/common"; +import { deserializeTx } from "@meshsdk/core-cst"; + +import { toMeshUnit } from "../types/asset"; +import { + getAssetTransferMethod, + PaymentRequirements, + PaymentRequirementsExtraScript, + ResourceInfo, +} from "../types/payment-requirements"; +import { PaymentPayload } from "../types/payment-payload"; +import { X402Error } from "../types/errors"; +import { buildMasumiEscrowPayment } from "./masumi"; +import { buildScriptOutputDatum, resolveScriptAddress } from "../script"; + +/** + * Chain context a caller must supply to build a payment: the current tip's slot (for TTL) + * and the live protocol parameters (for min-UTXO/fee-aware balancing).
