Build the Arbitrum tx that completes a USDC deposit to HL.
Takes the EIP-2612 permit signature returned by /deposit and returns
a fully-encoded Bridge2.batchedDepositWithPermit call. The integrator’s
sponsor wallet (sender) broadcasts the returned tx — Compass does not
broadcast and does not hold gas keys.

Sponsor wallet address that will broadcast the returned tx (used for from and nonce).
Example:
"0x4A83b4413CF41C3244027e1590E35a0F48403F0c"
Response
Successful Response
Fully-encoded Arbitrum tx that completes a HL Bridge2 deposit.
