The [tapes page](/protocol/architecture/tapes) covers the model behind them. ## create Reserves a tape on-chain and saves its keypair locally. Defaults to 5 GiB for 100 epochs. Pass `--epochs ` for an exact number of epochs, counting the current one, or `--duration` (`12h`, `7d`, `4w`) to buy enough epochs to last that long from now at the network's current epoch duration. The new tape becomes the active tape for later commands unless you pass `--create-only`. This command spends TAPE immediately. It first checks that the wallet holds the TAPE cost and enough SOL for rent and fees, and stops with the amount needed if not. `--dry-run` prints the cost, estimated expiry, and wallet balance without reserving anything. ```bash theme={null} tape create --capacity 100m --duration 7d --create-only --out ./project.tape.json ``` ```text Output theme={null} tape address: E79y5bh5zTLq9h7SgPGRsDpcmTB1oa7YGscFFFiojy2D label: yk5y3rg6cwclvyz7sv763kttt2d2sinpzdm3chuzw72th45s2c3a capacity: 104857600 bytes epochs: active=241 expiry=410 epoch duration: 1h expires: ~2026-09-23 22:00 UTC (in 7d) cost: 0.0161226 TAPE + ~0.00564372 SOL active tape: unchanged ``` The label is the address in a lowercase form, the bucket name S3 tools and subdomain serving use. The expiry time is an estimate from the current epoch duration. The TAPE cost is exact; the SOL figure estimates account rent and transaction fees. Without `--out`, the keypair lands in `~/.tape/cassettes/.json`. Pass `--overwrite-key` to replace an existing file at the same path. ## list Lists every tape owned by the current wallet. ```bash theme={null} tape list ``` ```text Output theme={null} ID ADDRESS USED CAPACITY TRACKS ACTIV EXPIR 4 3fTapeAddressExampleBase58Value111111111111 87342 2147483648 1 12 24 7 9qTapeAddressExampleBase58Value111111111111 0 104857600 0 12 16 ``` ## info Shows a tape's on-chain state, including how many epochs remain and the estimated expiry time. ```bash theme={null} tape info ``` ```text Output theme={null} tape address: E79y5bh5zTLq9h7SgPGRsDpcmTB1oa7YGscFFFiojy2D label: yk5y3rg6cwclvyz7sv763kttt2d2sinpzdm3chuzw72th45s2c3a id: 4077 authority: 5ywthAPoHfzWKhrVNSbo5GFdPDcJy7gbmkyZQ8zSKFzY capacity: 104857600 bytes (562 used, 104857038 free) tracks: 4 next track number: 4 epochs: active=241 expiry=410 current=243 remaining=167 epoch duration: 1h expires: ~2026-09-23 22:00 UTC (in 6d 22h) ``` `remaining` counts epochs from the current one to expiry. Once the current epoch reaches the expiry epoch, `expires` reads `expired`. ## extend Adds epochs to a tape's reservation, either `--epochs ` or enough epochs to add a `--duration` such as `7d`. Extension is permissionless: any wallet can pay to extend any tape, which is how data outlives its original owner ([more on expiry](/protocol/architecture/tapes)). An expired tape cannot be extended. `--dry-run` shows the cost and new expiry without spending. ```bash theme={null} tape extend --duration 7d ``` ```text Output theme={null} tape address: 3fTapeAddressExampleBase58Value111111111111 added epochs: 168 new expiry epoch: 192 epoch duration: 1h expires: ~2026-09-24 08:00 UTC (in 7d 10h) cost: 0.328237056 TAPE + ~0.000005 SOL ``` ## resize Grows a tape's capacity, either by a delta or to a target total. The added capacity is charged for the epochs the reservation has left. `--dry-run` shows the cost without spending. ```bash theme={null} tape resize --add 100m tape resize --to 4g ``` ```text Output theme={null} tape address: 3fTapeAddressExampleBase58Value111111111111 added capacity: 104857600 bytes new capacity: 2252341248 bytes cost: 0.0170766 TAPE + ~0.000005 SOL ``` ## delegate Sets the tape's write delegate: a second key allowed to register, certify, and delete tracks without owning the tape. This is how a hosted S3 gateway writes to your tape without ever holding your keypair ([delegation](/protocol/architecture/tapes#delegation)). ```bash theme={null} tape delegate 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM ``` ```text Output theme={null} tape address: 3fTapeAddressExampleBase58Value111111111111 delegate: 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM ``` ## revoke Removes the tape's current write delegate. ```bash theme={null} tape revoke ``` `info`, `extend`, `resize`, `delegate`, and `revoke` accept `--tape` to target a tape other than the active one; `create` always makes a new one.
