/**
 * Transfers tokens or native currency from one account to another.
 * @param client - The client instance.
 * @param params - The transfer parameters.
 * @returns An array of transfer return types containing transaction hashes.
 *
 * @example
 * Transferring native tokens
 * ```typescript
 * await client.transfer({
 *   from: '0x0000000000000000000000000000000000000000',
 *   to: '0x0000000000000000000000000000000000000000',
 *   amount: 1n,
 * })
 * ```
 *
 * @example
 * Transferring `USDC` tokens on default chain
 * ```typescript
 * await client.transfer({
 *   from: '0x0000000000000000000000000000000000000000',
 *   to: '0x0000000000000000000000000000000000000000',
 *   amount: 1n,
 *   token: client.chain.contracts.USDC,
 * })
 * ```
 *
 * @example
 * Specifying gas fees. Default is to use `HIGH` fee level
 * ```typescript
 * await client.transfer({
 *   from: '0x0000000000000000000000000000000000000000',
 *   to: '0x0000000000000000000000000000000000000000',
 *   amount: 1n,
 *   gas: 100n,
 *   fees: { maxFeePerGas: 200n, maxPriorityFeePerGas: 300n },
 * })
 * ```
 *
 * @example
 * Usage with [LOW](../variables/providers_circle-wallets.LOW.html)
 * ```typescript
 * await client.transfer({
 *   from: '0x0000000000000000000000000000000000000000',
 *   to: '0x0000000000000000000000000000000000000000',
 *   amount: 1n,
 *   fees: LOW,
 * })
 * ```
 *
 * @example
 * Transfer USDC cross-chain using CCTP
 * ```typescript
 * const [ account_1 ] = await client.getAccounts({ address: '0x123', chain: ETH_SEPOLIA })
 * const [ account_2 ] = await client.getAccounts({ address: '0x321', chain: MATIC_AMOY })
 *
 * await client.transfer({
 *   from: account_1,
 *   to: account_2,
 *   amount: '20',
 *   token: ETH_SEPOLIA.contracts.USDC,
 * })
 * ```
