key

key formats a token id into a zero-padded, lexicographically-sortable key.

Mint

Mint creates the next token id and assigns it to \`to\`. Only sequential minting is supported (id is returned via the Mint event).

Transfer

Transfer moves token \`id\` from the caller to \`to\`. The caller must own the token (approvals are cleared on transfer).

Approve

Approve grants \`spender\` the right to transfer token \`id\`. Only the current owner may approve.

ownerOf

approvedOf

balanceOf

balanceOf returns how many tokens \`owner\` holds.

exists

exists reports whether token \`id\` has been minted (and not since moved away).

totalSupply

totalSupply returns the number of tokens in circulation.

OwnerOf

BalanceOf

BalanceOf is the exported read-only accessor for balanceOf.

TotalSupply

TotalSupply is the exported read-only accessor for totalSupply.

Render
