Load ASA configuration and on-chain parameters by asset ID (Algod).

Return one account's balance and frozen flag for an ASA (Algod account info).

List ASA holdings for an account via Indexer (paginated). Optional assetId filter.

Build an unsigned ASA transfer (axfer). Amount is in base units. Optional closeRemainderTo closes the sender holding after transfer.

Build an unsigned ASA opt-in (0-amount self transfer).

Build an unsigned ASA transfer that closes the sender's holding (set closeRemainderTo). Supply full balance as amount.

Read ARC-200 name, symbol, decimals, and totalSupply (ulujs + simulation).

ARC-200 balanceOf(address) as base units (string in response).

ARC-200 allowance(owner, spender) in base units.

ARC-200 hasBalance(address) — whether the account has a non-zero balance box (ulujs dual-schema read).

ARC-200 hasAllowance(owner, spender) — allowance box present / non-zero (ulujs dual-schema read).

Fetch ARC-200 contract events (Transfer + Approval) via indexer (ulujs getEvents).

Simulate ARC-200 transfer and return unsigned txn group as base64 strings (sign with UluWalletMCP).

Simulate ARC-200 transferFrom(spender, from, to, amount); spender signs.

Simulate ARC-200 approve(spender, amount); owner signs.

Build unsigned NT200 withdraw(amount) txn. Withdraws ARC-200 wrapped network tokens or ASAs; token holder must be opted in to the underlying asset. One txn (ulujs CONTRACT + abi.nt200).

Build unsigned NT200 deposit(amount) txn(s). Deposit network token (payment) or ASA (axfer) preceding app call. For network: payment + app call; for ASA: set assetId for axfer + app call. Uses ulujs CONTRACT + abi.nt200.

Build unsigned NT200 createBalanceBox(address) txn(s). Creates a balance box for the specified address if it doesn't exist. May include payment txn for box creation cost. Uses ulujs CONTRACT + abi.nt200.

Aggregate ARC-72 facts: totalSupply; if tokenId set, owner, tokenURI, approved; optional supportsInterface (8-hex selector).

ARC-72 ownerOf(tokenId).

ARC-72 balanceOf(address) — number of NFTs owned.

ARC-72 getApproved(tokenId).

ARC-72 isApprovedForAll(owner, operator).

ARC-72 tokenURI(tokenId) as UTF-8 string (null bytes stripped by ulujs).

ARC-72 totalSupply().

Fetch ARC-72 Transfer, Approval, ApprovalForAll events (ulujs getEvents).

Simulate ARC-72 transferFrom(from, to, tokenId). Signer is sender (owner or approved operator).

Simulate ARC-72 approve(approved, tokenId); owner signs.

Simulate ARC-72 setApprovalForAll(operator, approved). Uses arccjs directly (ulujs wrapper is broken). Owner signs.
