erc1155

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

An idiomatic gno.land port of the Solidity ERC-1155 multi-token standard. One realm manages many distinct token ids, each with independent fungible balances tracked in an avl.Tree keyed by (owner, id), plus a per-id total supply. It keeps the core ERC-1155 ideas — minting, single transfers, balance and supply queries, and events — while dropping the Solidity-specific machinery (operator approvals, safe-transfer callbacks) that has no analog on gno.land.

Transactions

• Mint(cur realm, to address, id int, amount uint64) — mint amount of token id to to; increases that id's total supply.
• TransferSingle(cur realm, to address, id int, amount uint64) — move amount of token id from the caller to to.

Read-only

• BalanceOf(owner address, id int) uint64 — balance of one owner for one id.
• TotalSupply(id int) uint64 — total minted for a given id.
• Render(path string) — Markdown balances table (owner · id · amount) and a per-id supply table.

Example

Mint(cur, g1owner..., 1, 100)      // 100 units of token #1 to g1owner
Mint(cur, g1owner..., 2, 5)        // 5 units of token #2
TransferSingle(cur, g1other..., 1, 40)  // caller sends 40 of token #1
BalanceOf(g1owner..., 1)           // -> 60
TotalSupply(1)                     // -> 100
