Grants ERC-20 allowance to the Boson Protocol contract. Must be called before commit_to_offer or deposit_funds when using non-native exchange tokens, unless you relay in metaTx mode with transferAuthorizations (built with a sign_receive_with_* tool) passed to send_meta_transaction. Returns unsigned transaction data.

Commits to an offer, creating an exchange and minting a voucher NFT. Caller is the buyer (signerAddress) unless 'buyer' param is set. For ERC-20 offers, call approve_exchange_token first. In metaTx mode, you can skip the approval by passing transferAuthorizations (built with a sign_receive_with_* tool) to send_meta_transaction. Returns unsigned transaction data.

Atomically commits to an offer and immediately redeems the voucher in a single transaction via the OrchestrationHandler. Buyer (signerAddress) must already hold any required ERC-20 allowance (approve_exchange_token), or, in metaTx mode, pass transferAuthorizations to send_meta_transaction.

Deposits ERC-20 or native tokens into an entity's protocol treasury (e.g. seller deposit). For ERC-20, call approve_exchange_token first.
