chore: update relayer-sdk to 0.4.1 and fix browser mock mode - #43
Merged
Conversation
- @zama-fhe/relayer-sdk → 0.4.1 (all packages) - @fhevm/solidity → ^0.11.1 - @fhevm/hardhat-plugin → ^0.4.2 - @fhevm/mock-utils → ^0.4.2 - ethers → ^6.16.0 (peer dep requirement) - @nomicfoundation/hardhat-ethers → ^3.1.3 (peer dep requirement) - Add turbopack resolveAlias for Node.js built-ins (fixes node-tkms fs error) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The wagmi config only included sepolia, so useSwitchChain had no hardhat chain to switch to. Now both chains and transports are always configured (hardhat transport is harmless in production). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Update relayer-sdk CDN URL to 0.4.1 in layout.tsx and constants.ts - Replace empty-module.js with browser-compatible fs shim that loads WASM files via synchronous XHR from public/ - Copy node-tkms kms_lib_bg.wasm to public/ so the fs shim can serve it - This allows @fhevm/mock-utils to run in the browser, enabling local encrypt/decrypt on hardhat without routing through the remote relayer Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Fix synchronous XHR binary loading using overrideMimeType instead of
responseType (which is not supported for sync XHR)
- Add tfhe_bg.wasm to public/ for browser serving
- Patch node-tkms postinstall to use globalThis.TextEncoder/TextDecoder
instead of require('util') (avoids breaking Privy's isKeyObject)
- Use empty-module.js fs shim in webpack fallback for production builds
