FuturePass

Calls

create

Create a [FuturePass]learn/glossary) account for the delegator who is able to make calls on behalf of FuturePass.

The dispatch origin for this call must be Signed.

Parameters:

• account: The delegated account for the FuturePass.

Namespace

api.tx.futurepass.create

Type

function create(
  account: SeedPrimitivesSignatureAccountId20
)

migrateEvmFuturepass

This extrinsic migrates EVM-based FuturePass assets to the Substrate-based FuturePass (native).

Parameters:

• owner - The account ID of the owner of the EVM-based FuturePass.

• evm_futurepass - The account ID of the EVM-based FuturePass.

• asset_ids - A vector of asset IDs representing the assets to be migrated.

• collection_ids - A vector of collection IDs representing the NFTs collections to be migrated.

Namespace

api.tx.futurepass.migrateEvmFuturepass

Type

function migrateEvmFuturepass(
  owner: SeedPrimitivesSignatureAccountId20,
  evm_futurepass: SeedPrimitivesSignatureAccountId20,
  asset_ids: Vec<u32>,
  collection_ids: Vec<u32>
)

proxyExtrinsic

Dispatch the given call through FuturePass account. Transaction fees will be paid by the FuturePass. The dispatch origin for this call must be Signed

Parameters:

• futurepass: The FuturePass account through which the call is dispatched

• call: The Call that needs to be dispatched through the FuturePass account

Namespace

api.tx.futurepass.proxyExtrinsic

Type

function proxyExtrinsic(
  futurepass: SeedPrimitivesSignatureAccountId20,
  call: Call
)

registerDelegateWithSignature

Register a delegator to an existing FuturePass account given message parameters for a respective signature.

Note

Note:

• Only FuturePass owner account can add more delegates.

• The signer is recovered from the signature given the message parameters (which are used to reconstruct the message).

You can assume the message is constructed like so:

--- solidity bytes32 message = keccak256(abi.encodePacked(futurepass, delegate, proxyType, deadline)); ethSignedMessage = keccak256(abi.encodePacked("\x19Ethereum Signed Message:\n32", message));

---

The dispatch origin for this call must be Signed.

Parameters:

• futurepass: FuturePass account to register the account as delegate; 20 bytes.

• delegate: The delegated account for the futurepass; 20 bytes.

• proxy_type: Delegate permission level; 1 byte.

• deadline: Deadline for the signature; 4 bytes.

• signature: Signature of the message parameters.

Namespace

api.tx.futurepass.registerDelegateWithSignature

Type

function registerDelegateWithSignature(
  futurepass: SeedPrimitivesSignatureAccountId20,
  delegate: SeedPrimitivesSignatureAccountId20,
  proxy_type: SeedRuntimeImplsProxyType,
  deadline: u32,
  signature: [u8;65]
)

setFuturepassMigrator

Update FuturePass native assets migrator admin account.

The dispatch origin for this call must be sudo/root origin.

Parameters:

• migrator: The new account that will become the FuturePass asset migrator.

Namespace

api.tx.futurepass.setFuturepassMigrator

Type

function setFuturepassMigrator(
  migrator: SeedPrimitivesSignatureAccountId20
)

transferFuturepass

Transfer ownership of a FuturePass to a new account. The new owner must not already own a FuturePass. This removes all delegates from the FuturePass. The new owner will be the only delegate; they can add more delegates.

The dispatch origin for this call must be Signed and must be the current owner of the FuturePass.

Parameters:

• current_owner: The current owner of the FuturePass.

• new_owner: The new account that will become the owner of the FuturePass.

Namespace

api.tx.futurepass.transferFuturepass

Type

function transferFuturepass(
  current_owner: SeedPrimitivesSignatureAccountId20,
  new_owner: Option<SeedPrimitivesSignatureAccountId20>
)

unregisterDelegate

Unregister a delegate from a FuturePass account.

The dispatch origin for this call must be Signed.

Parameters:

• futurepass: FuturePass account to unregister the delegate from.

• delegate: The delegated account for the FuturePass.

Note: If the caller is the FuturePass holder (owner), they can remove any delegate, including themselves. However, if the caller is not the owner, they must be the delegate and can only remove themselves.
