…-foundation#1912) * feat: refactor coinbase/x402 references to x402-foundation/x402 * fix: format * chore: changeset fragments for typescript, python and go
* chore: version typescript packages * chore: version python package * chore: version go package
…d settle (x402-foundation#1922) Made-with: Cursor
* add self-facilitation example * fix: regenerate examples/typescript lockfile against public npm registry Lockfile had tarball URLs pointing to internal Coinbase Artifactory, causing pnpm install to fail with ENOTFOUND in CI where that host is unreachable.
…on#1917) * Migrate to @signinwithethereum/siwe Migrate the SIWE dependency to the Ethereum Identity Foundation package. package.json now depends on @signinwithethereum/siwe; evm.ts import was updated to import SiweMessage from the new package. Added a changeset describing the migration. (pnpm lock updated to reflect the dependency change.) * Add siwe v4.1.0 entries to pnpm-lock Update examples/typescript/pnpm-lock.yaml to add @signinwithethereum/siwe@4.1.0 and @signinwithethereum/siwe-parser@4.1.0. Adds package resolutions and snapshot entries, registers peerDependencies (ethers and viem marked optional), and removes the older siwe@2.3.2 entry in the importer. This pins the example project to the siwe v4 parser/runtime and records its dependency graph in the lockfile.
* feat(specs): add Keeta exact scheme * feat(schemes/keeta): add transaction simulation to verification step This adds a few cheap checks to simulate the transaction and catch invalid blocks early on to prevent the server from doing expensive work unnecessarily.

…n#1967) * feat(bazaar): add MCP resource type support to Go SDK Add MCP tool discovery extensions to the bazaar package, achieving parity with the TypeScript and Python SDKs. Servers can now declare MCP tool discovery extensions alongside HTTP resources, and facilitators can detect and extract them from payment payloads. Co-Authored-By: Claude <noreply@anthropic.com> * fix: gofmt formatting and gocritic if-else-chain lint Co-Authored-By: Claude <noreply@anthropic.com> * fix(bazaar): transport enum, doc examples, inline helper, add negative tests - Fix transport schema enum to include both valid values (streamable-http, sse) instead of only the provided value, matching TypeScript SDK behavior - Fix doc.go examples to use bazaar.BAZAAR.Key() instead of bazaar.BAZAAR - Inline createMcpDiscoveryExtension into DeclareMcpDiscoveryExtension - Add negative validation tests for wrong type and empty toolName - Add edge case tests for whitespace-only toolName and invalid transport Co-Authored-By: Claude <noreply@anthropic.com> * feat(mcp): wire extensions into PaymentWrapper 402 response Add Extensions field to PaymentWrapperConfig and pass it through to the PaymentRequired struct in 402 responses. This brings the MCP payment wrapper to parity with the HTTP middleware's RouteConfig.Extensions support, enabling bazaar discovery extensions in MCP tool responses. - Add Extensions map to PaymentWrapperConfig (types.go) - Set extensions in paymentRequiredResult (server.go) - Add unit tests for extensions present/absent in 402 (server_test.go) - Declare bazaar MCP extension in E2E server (main.go) - Add bazaar extension integration test (mcp_evm_test.go) Co-Authored-By: Claude <noreply@anthropic.com> * feat(mcp): wire TS extensions into 402 responses + Go integration tests Add extensions support to the TS MCP PaymentWrapperConfig and pass it through to createPaymentRequiredResponse so bazaar discovery metadata appears in 402 responses. Wire the E2E server with declareDiscoveryExtension for the get_weather tool. Add Go mocked-transport integration tests (5 cases) covering the full client↔server payment flow to match TS mcp-payment-flow.test.ts coverage. Co-Authored-By: Claude <noreply@anthropic.com> * fix: prettier formatting in MCP test files Co-Authored-By: Claude <noreply@anthropic.com> * fix(bazaar): address PR review feedback from @CarsonRoscoe - Use strings.TrimSpace for toolName validation to reject whitespace-only names - Allow custom transport values through schema validation (only enum for known transports) - Fix whitespace toolName test to assert error instead of success - Remove conditional guard in TS bazaar extension test so assertions always run Co-Authored-By: Claude <noreply@anthropic.com> * fix(bazaar): allow custom transport values in TS to match Go behavior Widen transport type from "streamable-http" | "sse" to string, and only apply enum constraint in schema for known transport values. This matches the Go-side fix so custom transports pass validation in both languages. Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>
…d networks support for Typescript (x402-foundation#1560) * Migrate all code from branch-algorand-v2-typescript-algokit * Update format and lint pass on core and examples * Reformat template files * Update: Coinbase review changes applied * Fix Paywall builder pattern * Update: Reverted e2e/legacy, Remove: src/exact/v1 and src/v1 * Add Faucets URLs to AVM README * Optimizing and shrinking PR * Remove dead import * Add optimization changes related unit tests * Update coinbase review changes applied * Update avm e2e, rebased to latest, linted and formatted * Fix avm template format * Remove python and Go AVM templates, Made AVM optional to facilitator and Add SERVER_ADDRESS * Lint and format * Update: made AVM optional in proxy.ts * Rebased and Replayed some commits * Reset e2e pnpm-lock.yaml * Replayed correct updated lockfiles * Reverted accidentally overwritten files during rebase replay * Revert accidental overwritten files in examples
…rdcoding USDC (x402-foundation#1973) The EVM paywall hardcodes "USDC" as the token label in all display text. The payment requirements already carry the token name in extra.name (populated by the server from the default asset registry), but the paywall ignores it. Read extra.name from the first payment requirement and use it for all user-facing token text. Falls back to "USDC" when extra.name is absent (backward compatible with EIP-3009 tokens). 5 display strings updated: - Header: "please pay $X {tokenName}" (was "USDC") - Testnet prompt: "Need {tokenName} on {chainName}?" (was "USDC") - Balance: "$X {tokenName}" (was "USDC") - Amount row: "$X {tokenName}" (was "USDC") - Error: "Make sure you have {tokenName} on {chainName}" (was "USDC") Regenerated Go, Python, and TS paywall templates.
…ME (x402-foundation#1998) The Go EVM mechanism README (introduced in x402-foundation#1983) listed only 4 chains under "Networks with default assets configured": - Base Mainnet, Base Sepolia, MegaETH Mainnet, Monad Mainnet But `go/mechanisms/evm/constants.go` configures 10, and the main docs table at `docs/core-concepts/network-and-token-support.mdx` lists all 10. Restore parity with the constants and the main docs table, in the same order as the mdx table: - Base, Base Sepolia, Polygon, Arbitrum One, Arbitrum Sepolia, Monad, Stable, Stable Testnet, MegaETH, Mezo Testnet All entries verified against `NetworkConfigs` in `go/mechanisms/evm/constants.go`. Follow-up to x402-foundation#1983 which introduced this README.

…ndation#2013) All direct viem dependencies now resolve to 2.47.12, adding chain definitions for Mezo Testnet (31611), MegaETH (4326), Stable (988/2201), and others that were missing from earlier locked versions. Lockfile-only change. No package.json range changes — all existing ^2.x ranges already accept 2.47.12.
…tion#1688) Implement the spec change from PR x402-foundation#1682, adding optional seller-defined memo support to the SVM exact scheme across all three SDKs. Client changes (TypeScript, Go, Python - both v1 and v2): - When extra.memo is present, use its UTF-8 value as memo instruction data - When absent, fall back to existing random 16-byte nonce behavior - Validate memo does not exceed MAX_MEMO_BYTES (256) limit Facilitator changes (TypeScript, Go, Python - both v1 and v2): - When extra.memo is present in requirements, verify exactly one memo instruction exists and its data matches the expected value - Return specific error codes: memo_count / memo_mismatch Constants added: - MAX_MEMO_BYTES / MaxMemoBytes (256) across all languages - ERR_MEMO_MISMATCH, ERR_MEMO_COUNT (Python/Go) - ErrMemoExceedsMaxSize (Go client) Tests added: - TypeScript: 4 memo tests in duplicateTx.test.ts - Go: TestSellerMemo with 4 subtests in duplicate_tx_test.go - Python: TestSellerMemo class with 4 tests in test_duplicate_tx.py Closes x402-foundation#1682

…ation#1527) Adds wallet-agnostic smart wallet verification to the SVM facilitator. Verifies payment outcomes by inspecting CPI inner instructions from transaction simulation, rather than parsing each wallet type's proprietary instruction format. Works for any smart wallet program (Squads, Swig, SPL Governance, Metaplex Core, etc.) that executes TransferChecked via CPI. Dual-path verification: - Path 1 (static): strict positional instruction validation for standard wallets. Fast, preserves existing behavior. Instruction cap raised 6 -> 7 so Phantom transactions carrying wallet-injected Lighthouse assertions pass statically (see x402-foundation#828, x402-foundation#2097). - Path 2 (simulation): outcome-based verification reached only when Path 1 fails for a recoverable layout reason. Semantic rejections (amount/mint/ recipient/memo mismatch, self-spend, failed simulation) return their real reason instead of being masked behind a smart_wallet_* code. Security model: - Fee payer isolation (fee payer never appears in instruction accounts), resolving Address Lookup Tables first so hidden accounts are caught. - Operator-configurable compute budget caps. - Program allowlist gating which programs reach simulation (Squads x2, Swig, SPL Governance, Metaplex Core, Lighthouse). - Exactly one matching TransferChecked in the CPI trace. - Post-settlement verification (TOCTOU defense): confirms the transfer executed on-chain via inner instructions, with a balance-delta fallback for both SPL Token and Token-2022. - Seller-required memo enforced in Path 2 at parity with Path 1. The internal _verify reports which path validated the payment so settle() knows when post-settlement verification is required without re-deriving it. The constructor requires all four smart-wallet signer methods (including fetchAddressLookupTables) so misconfiguration fails at construction, not at verify time. 15 dedicated smart-wallet tests plus path-classification, ALT-failure, and 7-instruction Phantom coverage. 190/190 passing. Rebased onto current main, preserving the message-hash settlement cache key. Made-with: Claude Code
…ication (x402-foundation#2505) PR x402-foundation#1527 merged without a changeset, so the simulation-based smart wallet verification feature would ship without a version bump or changelog entry. This adds the missing @x402/svm minor changeset. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(evm): add auth-capture client scheme Client-side auth-capture for @x402/evm: detects auth-capture payment requirements and signs the payload (ERC-3009 default, Permit2 alternative) over the payer-agnostic PaymentInfo hash.
