tape write puts data on the active tape. It takes a file path, an inline message, or stdin.
Writing needs a connection, a signing key, and a reserved tape. For Tapenet, complete
the wallet and funding setup, then follow the
CLI quickstart to reserve a tape.
The write command
Three input forms, one command:Output
--tape to target a tape other than the active one.
Size decides what happens. Inputs up to 825 bytes are written inside the transaction itself and return when the Solana write finalizes. Larger inputs up to 64 MiB become one certified track and return its address. Files over 64 MiB are written as streams and return a stream-manifest address. Those thresholds are CLI defaults, and the writing page explains the paths behind them; tracks covers the vocabulary.
Certification is part of the flow. When the command returns an address for a coded write, the track is certified: the network has proven it holds your data.
Named objects
tape write stores raw data by address. To store under a name, so the data shows up in listings, use tape object put instead. The objects page covers those commands.
