v0.2.0

v0.2.0 - 2026-07-03

🩹 Fixes

• Initial release with EVM-only support and single-network routing.

📖 Changes

What's New:

• Multi-network (EVM + SVM) support: Routes now accept payment from both EVM (Base, etc.) and Solana networks simultaneously, matching @x402/express behaviour.
• TNetworkPayment type -- per-network entry with optional scheme, price, network, payTo, description, and mimeType overrides.
• TRoutePayment type -- replaces the old TX402Config; supports an accepts array for full multi-network control.
• TScheme type -- "exact" | "upto" | "batch-settlement".
• accepts array field on TRoutePayment -- pass an explicit list of network entries for full control.
• config.networks array -- replaces the single network + address pair; supports both EVM and SVM entries project-wide.
• BunAdapter -- new class implementing @x402/core HTTPAdapter directly against Bun.BunRequest, handling headers, method, path, URL, query params, user-agent, and accept header.
• Scheme registration is now driven by the resolved accepts list; every unique network is registered exactly once (EVM registers exact, upto, and batch-settlement; SVM registers exact).
• X402Builder now maintains a static server cache (_serverCache + _initPromises) so each route's x402HTTPResourceServer is initialized only once across all requests, preventing duplicate SVM feePayer lookups.
• Payment flow delegates entirely to @x402/core's x402HTTPResourceServer.processHTTPRequest and processSettlement, replacing the hand-rolled verify/settle/decode chain.
• CORS headers (Access-Control-Allow-Origin: *, Access-Control-Expose-Headers: *) are now attached to all 402 and settlement responses.
• Handler cancellation: if the route handler throws or returns a 4xx/5xx, cancellationDispatcher.cancel() is called before returning.
• Facilitator errors during settlement are caught and returned as 502 JSON responses instead of being re-thrown.
• X402Exception now defaults to error code 502 instead of 402.

Changes:

• config/x402.ts no longer has a version field at all (the old x402Version/version: 1 key is gone project-wide); it now ships with a flat networks array containing Base mainnet (eip155:8453) and Solana mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp) entries instead of a single network + address + testnet block.
• Default scheme is "exact".
• X402Builder resolves networks via a 4-level priority cascade: explicit accepts array -> route single-network shorthand (network + payTo) -> config networks block -> built-in defaults (Base + Polygon + Arbitrum + World Chain for EVM; Solana mainnet for SVM).
• setPaywall() removed; replaced by setRoutePayment(config?: TRoutePayment).
• setConfig() removed; per-route metadata (description, mimeType, scheme, price) are now fields on TRoutePayment.
• setFacilitator() now accepts TFacilitator (a plain { url?: string, createAuthHeaders?: () => Promise<...> } object) instead of the old FacilitatorConfig; defaults to @coinbase/x402 facilitator.
• middleware() return type tightened to Promise<Response>.
• Dependency x402 replaced by @coinbase/x402 ^2.1.0, @x402/core ^2.17.0, @x402/evm ^2.17.0, and @x402/svm ^2.17.0.
• src/types/ directory added; types are now exported from their own module instead of being inlined in builder files.
• Build script now includes a types step (cp -rf src/types dist) so type definitions are copied alongside compiled output.
