Answer 1

For web3.js users:

await connection.getParsedTransactions(signatures, {
  maxSupportedTransactionVersion: 0,
});

See https://docs.solana.com/developing/versioned-transactions for information on transaction versions.

Answer 2

Be sure to add the "maxSupportedTransactionVersion" param to your call to correctly get v0 transactions. That means doing:

curl --location --request POST 'http://api.mainnet-beta.solana.com/' \
  --header 'Content-Type: application/json' --data-raw \
' { "jsonrpc": "2.0", "id": 1, "method": "getConfirmedTransaction", "params": ["5HbX6YFiQJsUhG1RM6YN8KNNY86rEpRJpG9WUWJmirAeiby5B6b6nH5qK43xctCxhecLKCmdKzuA1uFqFrLMfALg", {"encoding: "json", "maxSupportedTransactionVersion":0} ] }

Sorry for the rough formatting, but that should do it! You can learn more about the optional parameters at https://docs.solana.com/developing/clients/jsonrpc-api#gettransaction
