PR-Codex overview

This PR refactors the codebase to replace the usage of web3 with kit.connection.viemClient for transaction handling and account management, enhancing consistency and potentially improving performance.

Detailed summary

• Replaced web3 calls with kit.connection.viemClient.request in various account commands.
• Updated display functions from displaySendTx to displayViemTx.
• Modified account address handling using getAddress instead of toChecksumAddress.
• Refactored transaction handling in dkg commands to use encodeFunctionData and waitForTransactionReceipt.
• Changed test utilities from testLocallyWithWeb3Node to testLocallyWithNode.
• Consistently used newKitFromProvider for initializing kit in tests.

Serialize bigint threshold before logging DKG group data

In the viem path, getBlsKeys decodes the uint256 threshold as a bigint, so JSON.stringify(group) throws TypeError: Do not know how to serialize a BigInt when users run dkg:get --method group. The previous web3 call returned stringified numbers, so this is a regression that makes the group method unusable.

Wait for DKG start tx receipt before printing success

The custom send implementation returns kit.connection.sendTransaction(...), which resolves to a transaction hash, not a mined receipt; displayTx therefore completes as soon as the hash is returned and the command prints DKG Started! before confirmation. On non-instant mining networks (or if the tx later reverts), this can falsely report success and cause subsequent DKG steps to run too early.
