Scanning a transaction

Scan transactions in order to receive recommended actions, tailored warnings and human-readable simulation results explaining what the transaction will do.

const params = {
    chain: 'solana',
    chainId: 101,
    transactions: [
    'AQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABAAIFRcely+GNw4HsXvDZ2vi8ZHSvnfYAbuGTK5XjxGyUJ60JrJ+YHtCWDBeA0FSzvcigxpHxRg4haKu4qFquf9nwtxDLqeLGT1Y9D3jvRn8BJWyEq8LHFGZpD+vfskCcD4EGAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAGp9UXGSxWjuCKhF9z0peIzwNcMUWyGrNE2AYuqUAAAD1D6qTjIhI3IvLaoY+jcKrCp7I8+Di2XK6tV2y4c2liAgMDAgQABAQAAAADAgABDAIAAAAA4fUFAAAAAA==',
