Check this yourself

This page reads FastNEAR's public transaction index and stores nothing. This command asks a NEAR archival node for the same transaction and needs no keys.

curl -s https://archival-rpc.testnet.fastnear.com -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"tx","params":{"tx_hash":"77FPrEgDqhxWa2dAB57iyVx9kbBQc3cFu2oqiWDfGqEd","sender_account_id":"kceenwa.testnet","wait_until":"FINAL"}}'

Vouch has its own page because testnet.nearblocks.io stopped indexing on 27 Sep 2026, so it can't show newer transactions.
