  • Magic Link embedded wallets: the Content Security Policy allow-list that causes [-32603] Failed to fetch, and pinning the absolute Hashio relay URL.
  • ~900k gas for HBAR transfers and contract writes through the relay — 120k reverts on-chain while the client reports success.
  • HTS transfers must target the ECDSA evm_address alias, never the long-zero form, or the token precompile reverts with empty data.
  • Verifying USDC from the Transfer log on /contracts/results/{hash}, plus mirror-node polling and revert decoding into human sentences.
  • x402 profile on Hedera, the bespoke mandate-vault pattern, Sourcify v2 verification for HashScan, and the A2A / AP2 / UCP + RFC 9421 layer.
