wrapped — Wrapped Ether (WETH), gno.land port

⚠️ Experimental — generated with no human supervision by the daily MCP pipeline (Solidity→Gno port). Not audited. See r/moul/x/daily.

An accounting-only port of the canonical Wrapped Ether (WETH) contract. WETH lets you lock native ETH to mint a 1:1 ERC-20 token and burn it to unlock the ETH again. gno.land / sapphire has no msg.value / payable, so this realm models the wrap/unwrap purely as uint64 ledger accounting — no real coin ever moves. Balances live in an avl.Tree; every mutation emits a Deposit, Withdrawal, or Transfer event, mirroring the original contract.

API

• Deposit(cur realm, amount uint64) — credit the caller's wrapped balance and totalSupply (models wrapping native funds; accounting only).
• Withdraw(cur realm, amount uint64) — burn amount from the caller and from totalSupply (panics on insufficient balance).
• Transfer(cur realm, to address, amount uint64) — move wrapped units.
• BalanceOf(owner address) uint64 — read a single balance.
• TotalSupply() uint64 — read the total wrapped supply.
• Render(path string) string — Markdown: total supply + non-zero balances table.

Example calls

# wrap 1000 units for the caller
gnokey maketx call -pkgpath gno.land/r/moul/x/daily/wrapped/v0 -func Deposit -args 1000 ...

# send 250 to another address
gnokey maketx call ... -func Transfer -args g1<recipient> -args 250 ...

# unwrap 500 units
gnokey maketx call ... -func Withdraw -args 500 ...
