Quick Start

Connect wallet and enter a devnet mint.
Initialize Vault, then generate sender keys and initialize your shielded account.
Shield tokens, generate off-chain transfer payload, and submit private transfer.
Apply pending balance on the recipient account, then unshield if you are the recipient owner.
Optional: use Arcium Bridge settle for public SPL settlement after off-chain compute.

Arcium Bridge (Devnet)

Use this to set authorized verifier for bridge settlement.

Private Transfer (Arcium Path)

Sends transfer_private_arcium. Off-chain planner uses crypto_helper for ElGamal ciphertexts and sigma proofs; result_id is derived as SHA-256 over inputs + outputs.
