• transfer(api: ApiPromise, destination: ChainOrDomain, receiver: string, amount: Amount): Promise<SubmittableExtrinsic>: Creates a transaction to transfer a specified amount to a receiver on a given destination, which can be either the consensus chain or a specific domain.

Types:

• Amount: BigInt | number | string
  Represents the amount to be transferred.

• Consensus: { type: 'consensus' }
  Indicates that the destination is the consensus chain.

• ChainOrDomain: Consensus | Domain
  A union type representing either the consensus chain or a domain.

• Domain: { type: 'domain'; domainId: number }
  Specifies a domain as the destination, identified by a domainId.

---

Usage Example

// For transferring to the consensus chain
await transfer(api, { type: 'consensus' }, 'receiverAddress', amount)

// For transferring to a specific domain
await transfer(api, { type: 'domain', domainId: 1 }, 'receiverAddress', amount)

note

The transfer function returns a Promise that resolves to a SubmittableExtrinsic, which can be signed and submitted to the blockchain.
