WTF News (Week 9)

Hello and welcome to issue number five of WTF News, our biweekly status update.

Since our last post, we've settled on viem for the time being. It fixed our caching issues, and has excellent TypeScript support!

Code Changes🔗

• Migrate from ethers to viem.
• Pass errors from Ganache over postMessage then the WebSocket.
• Increase the slow test timeout.
• Disable minify by default. Now test source code is understandable in Mocha's HTML output!

New Tests🔗

• eth_getTransactionCount for contract accounts.
• eth_getCode returns the contract's bytecode.
• eth_newBlockFilter returns new blocks.
• eth_getStorageAt can read contract storage.
• eth_getTransactionByBlockHashAndIndex and eth_getTransactionByBlockNumberAndIndex get transactions.
• eth_getTransactionReceipt can get receipts.
• A whole lot of filter tests.

Upstream Issues🔗

• Ganache returns null from several endpoints, and it's unclear if that's allowed in the specification (ethereum/execution-apis#288.)
• Getting transactions by index beyond the end of the block throws an exception (trufflesuite/ganache#4435.)
